As data centers continue to boom throughout Texas, a new report from the Houston Advanced Research Center (HARC) warns that the trend could strain the state’s water supply.

HARC estimates Texas data centers used 25 billion gallons of water in 2025—and that the demand for water will continue to rise to meet the needs of the 464 data centers currently in Texas, as well as 70 additional sites currently under development.

In the report, titled “Thirsty Data and the Lone Star State: The Impact of Data Center Growth on Texas’ Water Supply,” The Woodlands-based nonprofit says that water use for cooling data centers is expected to double or triple by 2028 on the national level. If projections hold, the total annual water use for data centers in Texas will increase by 0.5 percent to 2.7 percent by 2030, or to between 29 billion and 161 billion gallons of water consumed.

Data centers often use water for cooling, though water demand is dependent on the type of cooling used, the size and type of the data center. Although used water can be reused, some new water withdrawals are always needed to replace evaporated water and other systems’ water losses. Water is also used to cool the power plants that generate electricity used by the data centers.

The HARC report offers guidance to address the overall concerns of water demands by data centers, including:

Dry cooling methods
Increased reliance on wind and solar energy sources
Alternative water supplies, like treated wastewater or brackish water for cooling
Adjusted operating schedules to accommodate water usage
Partnering with local companies to develop projects that reduce water leaks
Companies creating their own water infrastructure investments

The report goes on to explain that the Texas State Water Plan, produced by the Texas Water Development Board, projects shortages of 1.6 trillion gallons by 2030 and 2.3 trillion gallons by 2070. HARC posits that the recent surge in water demand from AI data centers is not fully reflected in those projections.

"Texas water plans always look backward, not forward," the report reads. "That means the 2027 water plan, which is in development now, will be based on 2026 regional water plans that do not include forecasted data center water use. Data centers that began operation in 2025 will not be added to the State Water Plan until 2032."

Currently, there are no state regulations that require data centers to report how much water they use. However, the Public Utility Commission of Texas (PUC) plans to survey operators of data centers and cryptocurrency mining facilities on their water consumption, cooling methods and electricity sources this spring. It is expected to release the results by the end of the year. The companies will have six weeks to respond. The Texas Water Development Board will assist the PUCT on the questions.

“I think we all recognize the importance of data centers and the technology they support and what they give to our modern-day life,” PUC Commissioner Courtney Hjaltman said during the last commission meeting. “Texans, regulators and the legislature really need that understanding of data centers, really need to understand the water they’re using so that we can plan and create the Texas we want.”

DOE proposes cutting $1.2 billion in funding for hydrogen hub

funding cuts

The U.S. Department of Energy has proposed cutting $1.2 billion in funding for the HyVelocity Gulf Coast Hydrogen Hub, a clean energy project backed by AES, Air Liquide, Chevron, ExxonMobil, Mitsubishi Power Americas and Ørsted.

The HyVelocity project, which would produce clean hydrogen, appears on a new list of proposed DOE funding cancellations. The list was obtained by Latitude Media.

As of November, HyVelocity had already received $22 million of the potential $1.2 billion in DOE funding.

Other than the six main corporate backers, supporters of HyVelocity include the Center for Houston’s Future, Houston Advanced Research Center, Port Houston, University of Texas at Austin, Shell, the Texas governor’s office, Texas congressional delegation, and the City of Fort Worth.

Kristine Cone, a spokeswoman for GTI Energy, the hub’s administrator, told EnergyCapital that it hadn’t gotten an update from DOE about the hub’s status.

The list also shows the Magnolia Sequestration Hub in Louisiana, being developed by Occidental Petroleum subsidiary 1PointFive, could lose nearly $19.8 million in federal funding and the subsidiary’s South Texas Direct Air Capture (DAC) Hub on the King Ranch in Kleberg County could lose $50 million. In September, 1Point5 announced the $50 million award for its South Texas hub would be the first installment of up to $500 million in federal funding for the project.

Other possible DOE funding losses for Houston-area companies on the list include:

A little over $100 million earmarked for Houston-based BP Carbon Solutions to develop carbon storage projects
$100 million earmarked for Dow to produce battery-grade solvents for lithium-ion batteries. Dow operates chemical plants in Deer Park and LaPorte
$39 million earmarked for Daikin Comfort Technologies North America to produce energy-efficient heat pumps. The HVAC company operates the Daikin Texas Technology Park in Waller
Nearly $6 million earmarked for Houston-based Baker Hughes Energy Transition to reduce methane emissions from flares
$3 million earmarked for Spring-based Chevron to explore development of a DAC hub in Northern California
Nearly $2.9 million earmarked for Houston-based geothermal energy startup Fervo Energy’s geothermal plant in Utah

Houston-area selected among 7 regions for $7B federal hydrogen hub investment

HyVelocity

Not only has a Houston-area project been announced as one of the seven regions to receive a part of the $7 billion in Bipartisan Infrastructure Law funding to advance domestic hydrogen production — but the Bayou City is getting one of the largest pieces of the pie.

President Biden and Energy Secretary Jennifer Granholm named the seven regions to receive funding in a White House statement today. The Gulf Coast's project, HyVelocity Hydrogen Hub, will receive up to $1.2 billion — the most any hub will receive, per the release.

“As I’ve stated repeatedly over the past years, we are uniquely positioned to lead a transformational clean hydrogen hub that will deliver economic growth and good jobs, including in historically underserved communities," Houston Mayor Sylvester Turner says in a news release. "HyVelocity will also help scale up national and world clean hydrogen economies, resulting in significant decarbonization gains. I’d also like to thank all the partners who came together to create HyVelocity Hub in a true spirit of public-private collaboration.”

Backed by industry partners AES Corporation, Air Liquide, Chevron, ExxonMobil, Mitsubishi Power Americas, Ørsted, and Sempra Infrastructure, the HyVelocity Hydrogen Hub will connect more than 1,000 miles of hydrogen pipelines, 48 hydrogen production facilities, and dozens of hydrogen end-use applications across Texas and Southwest Louisiana. The hub is planning for large-scale hydrogen production through both natural gas with carbon capture and renewables-powered electrolysis.

The project is spearheaded by GTI Energy and other organizing participants, including the University of Texas at Austin, The Center for Houston’s Future, Houston Advanced Research Center, and around 90 other supporting partners from academia, industry, government, and beyond.

“Prioritizing strong community engagement and demonstrating an innovation ecosystem, the HyVelocity Hub will improve local air quality and create equitable access to clean, reliable, affordable energy for communities across the Gulf Coast region,” says Paula A. Gant, president and CEO of GTI Energy, in a news release.

According to the White House's announcement, the hub will create 45,000 direct jobs — 35,000 in construction jobs and 10,000 permanent jobs. The other selected hubs — and the impact they are expected to have, include:

Tied with HyVelocity in terms of funding amount, the California Hydrogen Hub — Alliance for Renewable Clean Hydrogen Energy Systems (ARCHES) — will also receive up to $1.2 billion to create 220,000 direct jobs—130,000 in construction jobs and 90,000 permanent jobs. The project is expected to target decarbonizing public transportation, heavy duty trucking, and port operations.
The Midwest Alliance for Clean Hydrogen (MachH2), spanning Illinois, Indiana, and Michigan, will receive up to $1 billion. This region's efforts will be directed at optimizing hydrogen use in steel and glass production, power generation, refining, heavy-duty transportation, and sustainable aviation fuel. It's expected to create 13,600 direct jobs—12,100 in construction jobs and 1,500 permanent jobs.
Receiving up to $1 billion and targeting Washington, Oregon, and Montana, the Pacific Northwest Hydrogen Hub — named PNW H2— will produce clean hydrogen from renewable sources and will create over 10,000 direct jobs—8,050 in construction jobs and 350 permanent jobs.
The Appalachian Regional Clean Hydrogen Hub (ARCH2), which will be located in West Virginia, Ohio, and Pennsylvania, will tap into existing infrastructure to use low-cost natural gas to produce low-cost clean hydrogen and permanently and safely store the associated carbon emissions. The project, which will receive up to $925 million, will create 21,000 direct jobs—including more than 18,000 in construction and more than 3,000 permanent jobs.
Spanning Minnesota, North Dakota, and South Dakota, the Heartland Hydrogen Hub will receive up to $925 million and create around 3,880 direct jobs–3,067 in construction jobs and 703 permanent jobs — to decarbonize the agricultural sector’s production of fertilizer, decrease the regional cost of clean hydrogen, and advance hydrogen use in electric generation and for cold climate space heating.
Lastly, the Mid-Atlantic Clean Hydrogen Hub (MACH2), which will include Pennsylvania, Delaware, and New Jersey, hopes to repurposing historic oil infrastructure to develop renewable hydrogen production facilities from renewable and nuclear electricity. The hub, which will receive up to $750 million, anticipates creating 20,800 direct jobs—14,400 in construction jobs and 6,400 permanent jobs.

These seven clean hydrogen hubs are expected to catalyze more than $40 billion in private investment, per the White house, and bring the total public and private investment in hydrogen hubs to nearly $50 billion. Collectively, they aim to produce more than three million metric tons of clean hydrogen annually — which reaches nearly one third of the 2030 U.S. clean hydrogen production goal. Additionally, the hubs will eliminate 25 million metric tons of carbon dioxide emissions from end uses each year. That's roughly equivalent to annual emissions of over 5.5 million gasoline-powered cars.

“Unlocking the full potential of hydrogen—a versatile fuel that can be made from almost any energy resource in virtually every part of the country—is crucial to achieving President Biden’s goal of American industry powered by American clean energy, ensuring less volatility and more affordable clean energy options for American families and businesses,” U.S. Secretary of Energy Jennifer M. Granholm says in the release. “With this historic investment, the Biden-Harris Administration is laying the foundation for a new, American-led industry that will propel the global clean energy transition while creating high quality jobs and delivering healthier communities in every pocket of the nation.”

HyVelocity has been a vision amongst Houston energy leaders for over a year, announcing its bid for regional hydrogen hub funding last November. Another Houston-based clean energy project was recently named a semi-finalist for National Science Foundation funding.

“We are excited to get to work making HyVelocity come to life,” Brett Perlman, president and CEO of Center for Houston’s Future, says in the release. “We look forward to spurring economic growth and development, creating jobs, and reducing emissions in ways that will benefit local communities and the Gulf Coast region as a whole. HyVelocity will be a model for creating a clean hydrogen ecosystem in an inclusive and equitable manner.”

Experts: How to better prepare Houston to combat climate related challenges

guest column

Houston is no stranger to hurricanes, and in recent years winter storms have become an increasing concern. Following the winter freeze in 2021, more than 4 million Texans were left without power, water, or heat. The state’s infrastructure system was adversely impacted concurrently — including workplaces, hospitals, transportation, homes, drinking water distribution, electric power generation, agriculture, and grocery stores. Now, a new potential disaster is on the horizon. Recent research shows Houston is most likely to be affected by wildfires, a climate-related challenge that our city has not previously faced.

According to the Gensler Research Institute’s 2022 U.S. Climate Action Survey, since 2019, only 18 percent of Americans believe their communities are built to withstand climate change. The good news is Americans overwhelmingly agree that addressing climate change is urgent. The question many are asking is — “How can we take action to better prepare buildings and cities to weather the climate challenge?” The solution is simple. In order to understand where we need to go, we must understand how we got here.

With a population that has more than doubled in the past 50 years, it is challenging for most Houstonians to imagine a time when The Bayou City was nothing more than agricultural lands and oil fields. Today, Houston is known for being the fourth-most populous city in the United States. It is a sprawling concrete jungle home to the world’s largest concentration of healthcare and research institutions. When reflecting on the past 50 years, one can’t help but evaluate the city’s successes and shortcomings. While Houston has succeeded in becoming a diverse, international city, we have sacrificed the very ecology that once made up one of the country’s most productive agricultural areas. By 1980, Houston possessed the least amount of green space per person in the country.

As new developments popped up across the city, it became difficult to convince developers to pursue third-party certifications such as LEED, a globally recognized symbol of sustainability that provides the framework for designing healthy, efficient, carbon saving buildings. We can credit Hines with being one of the few developers in Houston to prioritize green design during the early-2000s. City leaders also began advocating for resilient strategies and more green space to attract and retain international talent and businesses. In recent years, we have seen an increase in buildings that are achieving LEED certification, and soon it will become the baseline.

An example of a project leading the way for resilient design is The Houston Advanced Research Center (HARC). In 2017 the organization completed work on its LEED Platinum Certified headquarters which was designed to meet the ENERGY STAR certification rate of 99 (out of 100). This means that the building is more efficient than 99 percent of all office buildings in the United States. Skanska is another construction and development company bringing a sustainable mindset to downtown Houston with its work on Bank of America Tower. In 2019, the 775,000 square foot building became the largest LEED v4 Platinum Core and Shell certified project in the world to date and was developed with harvesting technology that will significantly reduce energy usage.

It’s also important to understand the impact that the climate crisis is having on people. 91 percent of U.S. Gen Z/Millennials have been affected by extreme weather events since 2019, the most of any generation. These experiences have resulted in two generations preparing to react and combat climate change and has encouraged a spirit of transparency among companies who choose to share their environmental goals and strategies.

For architects and designers, addressing building and energy codes is proving to be the next big design consideration. As codes progress in the coming years, the result will be more unique and unexpected building designs.

When reimagining the use of buildings, Architects Paulina Abella and Tayler Trojcak propose an experimental process for repurposing vacant buildings called High Hackers. The concept provides an opportunity for developers to offer prime downtown real estate to people with diverse skill sets, whom they call “hackers,” to pursue projects shaped by their individual ideas. These hackers—makers, artists, and academics—will work alongside one another in spaces that encourage them to coexist with creatives from other fields and disciplines. More importantly, it fosters a collaborative, organic, and innovative workflow.

When examining how you can better prepare and respond to ongoing climate-related challenges, we encourage prioritizing marginalized communities that are already experiencing most of the negative impacts. Promoting awareness and optimism in our communities is another simple yet effective way to make a difference. For businesses, creating a sense of continuity in the face of climate events, investing in energy and resource efficiency and adaptation, and addressing insurability and the long-term value of real estate will ultimately help lead Houston and its community members toward a place of preparedness and resiliency.

How can Houston's energy transition be built with the city's communities in mind? Through trust, public education, and intention, according to a panel of experts. Photo via Getty Images

Why it would be 'potentially catastrophic' not to include communities in the energy transition

overheard

As the energy sector transitions toward a more sustainable future, a Houston organization is driving forward the idea to do so with a community-based approach, as some experts discussed at a recent breakfast panel.

The Center for Houston's Future hosted a breakfast discussion on August 10, entitled "Building a Community-Based Approach to the Energy Transition," sponsored by BP Energy. The conversation covered various ways corporations, organizations, and individuals could work together to build this approach, including through education, upskilling, collaborations, and more.

The event kicked off with a keynote address from Brad Townsend, vice president of policy and outreach at the Center for Climate and Energy Solutions, who set the scene for the discussion.

“The energy transition offers an opportunity to build a thriving, just, and resilient net-zero economy that can benefit companies and communities alike" he says to the crowd. "It’s the chance to raise jobs standards and safely through local and federal policies, employ a practice change, cross-sector collaboration, and worker training.

“It's also an opportunity to diversify the workforce to better reflect local communities, including in Houston," he continues. "If we approach this engagement however as a box checking exercise or unwilling to really provide communities an opportunity to help shape projects, we’re destined to fail. Being genuinely open to feedback from communities and actively incorporating them into the decision-making process is foundational to generating the community buy-in that will be crucial to a successful energy transition.”

Here were some of the key takeaways from the event.

"When we talk about Houston we need to be cognizant that it is a huge geographical area, and you cannot speak to Houston as a monolith. You can't even speak to individual communities as single entities."

— Anne Bartlett, vice president of industry and community resources at Brazosport College.

"Our responsibility is to recognize and really understand our communities not just from labor market data perspective, but also by having conversations with people who know what’s happening on the ground," she continues. "Our charge is to recognize that yes, this is a regional opportunity but it really does need to be situationalized in our specific communities and recognize the strengths and the opportunities that are present in all of those."

"One of the opportunities and challenges that's part of this massive energy transition, which I think will not only bring about investments of billions of dollars but potentially trillions of dollars, is to utilize these significant investments as an opportunity to not only transform how we make, use, and transport energy, but also uplift these communities that are adjacent to the facilities where hydrogen and other resources will be will be produced."

— John Hall, president and CEO of Houston Advanced Research Center.

"We (need to) use this entire transformational effort to open the doors of opportunity for every community," he adds.

“While it is the right thing to do to bring in the full breath of diversity that we have, it's (also) absolutely necessary.”

— Mark Crawford, senior vice president at BP Energy.

"We're in in Houston. We are the most diverse city in the United States, and the United States is becoming more and more diverse," he explains.

"It is important to bring holistic solutions to communities. ... We can't do everything, but there are organizations working on the ground that are doing really great work. It's about companies going in and partnering with stakeholders on the ground who understand the communities so that we are bringing these wrap-around services."

— Crawford continues, noting that it's on companies like BP to tap into and support local entities.

“There's a fundamental shift that needs to happen in the way that we're talking about these jobs to really encourage young people to take advantage of resources that are made available, because we can integrate that into the educational curriculum, but unless students and young people are willing to move in that direction it's not going to make a difference.”

— Townsend says on the panel, addressing the sentiment that young people are told job security comes only with a college degree. The panelists agree this isn't the case anymore, yet that message is still being conveyed.

“I think it's really important to pull back and recognize the opportunity that's in the K-12 space — not only with the children and making sure that they're aware that these careers even exist, but perhaps just as importantly with their parents.”

— Bartlett says, adding that these kids will be the ones in thes jobs in 10 or so years, so that message needs to start being conveyed now.

“All of these things cost money. There are dollars that are out there right now that we are not leveraging — there are dollars that are available through the Texas Workforce Commission, through Chambers of Commerce. So, we're not talking about having to reinvent the wheel and having to go to our industry partners with palms up, we're talking about leveraging the resources that are already out there in a wiser way.”

— Bartlett says about the feasibility of workforce development programs.

“It would be unfortunate — (and) it would be potentially catastrophic — if we see the trillions and trillions of dollars invested over the next 20 years, and we have left behind 25 percent or more of citizens.”

— Hall says, emphasizing how important working with communities — and hearing their concerns — is to this process.

He later adds that he's worked with community leaders, and he knows they are optimistic — as is he — about this process. “These are not peculiar human beings. They have the same hopes and dreams that we have, and if we will take the step to just reach out and connect and communicate with sincerity, then those barriers are easier to overcome.”

The convergence of green banking with evergreen experimentation in support of a growing green economy sounds like just the right shade of green. Photo by micheile henderson/Unsplash

Green banking meets evergreen R&D with recent MOU

MONEY + MATTER

The term “Energy Transition” doesn’t merely imply change, it demands it. And with change comes another kind of change–usually of the dollars and cents kind.

While many aspire to embrace more sustainable and cleaner energy solutions in their communities, the affluence needed to deploy necessary infrastructure often sits just outside of reach. Until now, that is.

With the rise of “green banking,” securing financing for the adoption of energy efficiency, implementation of decarbonization technologies, and broader provision of renewable energy is now more accessible. Funds at green banks, backed by a blend of public and philanthropic contributions, tap into the modern trend of crowdfunding to support egalitarian and climate improvement efforts.

However, green bank financing is structured with repayment of–or a return on–capital expected at the end of the term, meaning approval tends only to be granted to proven and established projects well past the research and development stage. Given the Energy Transition is, for the most part, still in its infancy, clearing such hurdles can be difficult.

But Houston is full of dreamers and doers; researchers and entrepreneurs eager to tackle the next big challenge. It would come as no surprise then, that Texas’ first green bank, the Clean Energy Fund of Texas (“CEFTx”), bucks tradition with a novel Memorandum Of Understanding (“MOU”) co-signed by the Houston Advanced Research Center (“HARC”) to finance efforts staunchly entrenched in R&D activity.

As the Energy Transition foothold grows, Houstonians are compelled not just to invest in green initiatives, but to drive them. Which only makes sense, considering the deep expertise in energy innovation led most recently by the Houston-area shale revolutionaries from Mitchell Energy. Established over 40 years ago by George P. Mitchell himself, HARC plants the seeds of transformation at the intersection of science, resilience, sustainability, and the environment.

Per the March 29 news release from CEFTx, John Hall, President & CEO of HARC says, “We are excited to join forces with the team at Clean Energy Fund of Texas as they drive green investment in low-income and disadvantaged communities. Our research expertise and experience in managing state and federal grants will be a true benefit to Texans.”

The recent MOU brings Energy Transition visionaries the capital necessary to explore, test, develop, and deploy innovative solutions from conception to maturity. Entrepreneurs at all stages of the business lifecycle are encouraged to apply for funding on the CEFTx website or connect with HARC at an upcoming event to discover how the two entities can take ideas from dream to reality.

“It’s an honor to work with the esteemed researchers at HARC, who have been studying sustainability for decades,” says Stephen Brown of CEFTx in the release. “Together we can be even more effective at kickstarting investments in solar power, retrofits, and other technologies that help create the green workforce of tomorrow.”

The fresh approach to funding set up by CEFTx and HARC positions new companies to succeed and enables existing companies to progress in the transition to a more sustainable #futureofenergy. It’s just the sort of sense that is needed to truly drive change.

Houston solar manufacturer expands facility, production capacity

houston expansion

Solar tracking and manufacturing company PV Hardware USA is increasing its production capacity and expanding its Houston facility in an effort to meet growing demands.

The move marks the company's third expansion in the Houston area in three years. PV Hardware reports a 400 percent surge in national market growth over the past three years, as solar-based projects have been pivotal in energy resilience efforts.

PV Hardware plans to increase the capacity at its Houston facility by 42 percent, according to a news release. With the additional capacity, PV Hardware expects a 35 percent increase in production of pre-assembled parts. The company has not announced whether any additional employees will be hired or the costs of expansion.

In September, the company completed its new dedicated pre-assembly facility, which will help migrate difficult assembly into an easier manufacturing setting. The new pre-assembly area will also assist with streamlined field installation, enhanced schedule predictability and reduction of manual labor.

Citybiz reports that the expansion totals approximately 34,200 square feet.

PV Hardware USA aims to make solar installation more efficient. For large-scale solar projects, PV Hardware USA’s pre-assembly process helps to relieve assembly work done by installation teams. According to PV Hardware USA, it reduces the number of on-site components by 70 percent.

“Traditionally, manufacturers pushed the assembly burden onto the jobsite,” Rodolfo Bitar, vice president of business development for PVH USA, told Renewable Energy Magazine. “We ask a different question: what work can be done more efficiently before the equipment ever leaves the factory? By managing the assembly of 188 loose parts per row in our controlled manufacturing environment, we remove field complexity and make installation highly predictable.”

PV Hardware USA produces single-axis solar trackers made in Texas and has supplied over 52 gigawatts of solar trackers worldwide.

“The expanded presence in Texas underscores a long-term commitment: bringing world-class solar expertise to local American manufacturing, supporting communities, and serving as a reliable partner through the clean energy transition,” the company said in the release.

In July of 2025, the company opened its 95,000-square-foot facility, which was the second Houston location following its initial $30 million U.S. manufacturing facility, which, at 50,000 square feet, is one of America's largest solar tracker manufacturing facilities.

Gulf of Mexico marine life dramatically declined after BP spill, study says

Gulf Life

In a deep, dark part of the Gulf of Mexico, the number of marine animals plummeted by about 60% in the years following the 2010 Deepwater Horizon explosion, a new study found.

In a crucial part of the Gulf between the light surface and the darkest depths, where the BP-operated well failed and dumped 134 million gallons of oil, the number of fish found dropped by 63.5% from the year after the spill to 2015. Crustaceans, including shrimp and krill, a key food for whales, went down 62%, and larger animals like squid and octopuses fell 59.7%, according to a study published Monday in the journal PNAS.

And those populations haven't come close to recovering, the study found.

Researchers focused on the ocean's “twilight zone,” a vast area above the seafloor, where much of the surface marine life, including dolphins and whales, feast on creatures. Yet little is known about this gigantic ecosystem, and this region of the Gulf had not been studied before the 2010 spill, said study lead author Tracey Sutton, a biological oceanographer at Nova Southeastern University.

A 2011 post-spill exploration cited in the research, which used six sets of nets at different depths and acoustic sonar, gave scientists a good sense of how much sea life was in the area between the surface and 5,000 feet deep (1,500 meters). They returned to the same place with the same equipment three-and-a-half years later and found sea life was between one-third and one-quarter of what it was in 2011.

“We saw this big decline,” Sutton said. “The question was then why? So we looked at all of the natural variables we thought could account for it, namely temperature, oxygen supply and food. None of those vary with the decline. The event that did was the oil spill. So we think that’s the most likely cause of the decline.”

Researchers kept on sampling since 2015 and the low populations remained, with a slight rise in 2022 and 2023 that did not prove statistically significant or lasting, Sutton said.

Documenting the decline

Sutton's team documented the population declines with three different lines of evidence: what they caught in the nets, what their acoustic sonar found and genetic studies showing the species losing genetic diversity because of inbreeding.

A lot of marine life died instantly after the explosion, which killed 11 workers, and from nearly five months of leaking oil and gas. Those pollutants got stored in the eggs of survivors and subsequent generations of critters got more compromised and weaker, Sutton said.

BP spokesperson Paul Takahashi said the accident “forever changed” the company: “We have made many changes intended to help prevent an event like this from ever happening again.”

Both the oil and the dispersants used to clean the spill hurt fish, but in different ways, said study co-author Isabel Romero, a chemical oceanographer at the University of South Carolina. Oil is more toxic and an overall threat, but the dispersant breaks the oil into smaller droplets, increasing the exposure of animals that live in the deeper water column, she said.

Dispersants caused many problems, and new studies show that in future accidents, it would be better to avoid those chemicals and instead add agents that increase oil-munching microbes, said former National Science Foundation Director Rita Colwell, a University of Maryland environmental microbiologist who headed a 10-year, $500 million BP-funded program to study spill effects.

Sutton said his team couldn’t prove an exact causal link to the BP oil spill, but by eliminating the other possibilities and looking at the timing, it’s logically clear that the spill caused the problem.

The krill population dropped 72%. Lanternfish — odd fish with blue-green lights embedded over their bodies — are a third of what they used to be, Sutton said. The stunning but scary dragonfish — with sharp teeth, light organs and a lure attached to its head — also had big losses, he said.

“These are foundational species,” Sutton said. “They're the things most things eat. So it's no wonder that we had wholesale changes across the community.”

The inner ocean is more unknown than outer space

Scientists learned much about this unexplored area of the Gulf.

“One of our biggest findings from the whole thing is how connected the whole oceanic Gulf is from top to bottom because the animals move up and down,” Sutton said. “There are predators at the top that dive deep. Lots of things that are deep that come up at night. So the system is one very large pulsing system, rather than just a layered system like people might have thought beforehand.”

Outside scientists were especially bothered by where the spill damaged.

“We know more about space in some ways than we do about the inner ocean. Because we can’t see these regions, there is a tendency to assume everything is fine, but here we have a clear result showing that something went very wrong," Scripps Institution of Oceanography marine scientist Kaitlin Frasier said in an email.

Frasier, who wasn't part of the study released Monday, published a post-spill study in 2024 looking at Gulf of Mexico whales and dolphins, finding population drops as high as 83%.

“It’s shocking how a single failure in a drilling rig can have this vast and sustained impact over thousands of square kilometers, with little visible recovery over 13 years after the spill,” said Dalhousie University marine scientist Boris Worm, who wasn't part of the study. “It is important that we see this, because for the longest time these consequences were completely out of sight and out of mind.”

Worm and Colwell said this damage should be kept in mind as the world talks about deep-sea mining and increased oil drilling in deep waters.

According to the company, methane emissions are vented from most oil and gas facilities due to safety protocols, and operators are not able to capture the gas cost-effectively, leading operators to emit more than 14 million metric tons of methane per year in the U.S. and Canada. Founded in 2022, Capwell specializes in low and intermittent flow vents for methane capture.

The company began as a University of Pennsylvania senior design project led by CEO Andrew Lane. It has since participated in programs with Greentown Labs, the Rice Clean Energy Accelerator and the Creative Destruction Lab Energy Cohort at Texas A&M University. The company moved to Houston in 2023 and raised a pre-seed round. It deployed two commercial units this year, according to its application.

FlowCellutions

Energytech startup FlowCellutions is developing a chemistry-agnostic diagnostics platform for flow and metal-air batteries supporting data centers and critical infrastructure. The platform is designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from approximately seven years to more than 30 years. It has deployed four paid pilots and plans to take insights from the programs to develop its next-gen sensor platform technology.

CEO Becca Segel founded the company in 2022. It is a member of Greentown Labs, and Segel was a 2025 Activate Fellow. The company has raised over $2 million in non-dilutive funding and received a $1.5 million NSF SBIR Fast-Track award earlier this year.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A this month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Mars Materials

Clean chemical manufacturing business Mars Materials is working to convert captured carbon into resources, such as carbon fiber and wastewater treatment chemicals. The company develops and produces its drop-in chemical products in Houston and uses an in-licensed process for the National Renewable Energy Lab to produce acrylonitrile, which is used to produce plastics, synthetic fibers, and rubbers.

Founded in 2019 by CEO Aaron Fitzgerald, CTO Kristian Gubsch, and vice president of operations Trey Sheridan, the company has secured over $7.2M in financing and is backed by Bill Gates’ Breakthrough Energy, Shell, Black & Veatch, and other organizations. It won in the Minority-founded Business Category in last year's Houston Innovation Awards.

Solidec

Chemical manufacturing company Solidec has developed autonomous generators that extract molecules from water and air and convert them into pure chemicals and fuels that are free of carbon emissions on-site, eliminating the need for transport, storage, and permitting. The company was founded around innovations developed by Rice University associate professor Haotian Wang.

The company was selected for the Chevron Technology Ventures’ Catalyst Program, Greentown Labs, NSF I-Corps and was part of the first cohort of the Activate Houston program. It won first place at the 2024 startup pitch competition at CERAWeek. Solidec was founded in 2023 by Wang, who serves as an advisor, CEO Ryan DuChanois, and CTO Yang Xia. It closed a $2.5 million seed round in 2025.
