As I stood on the platform at the world’s largest stock exchange to ring the closing bell, surrounded by 130 people from across the energy industry, I saw it clearly: how the private sector will play a major role in getting us to an era of net zero. The people who power the energy industry will do the hard work. We’ve already begun. And we’re unafraid of the long journey ahead — something more than 40 of us exemplified that weekend by running a marathon.

The trip to New York City days ago was an exhilarating whirlwind. But it was also something much more: A chance to show the markets, the nation, and the world that Houston is leading the energy transition. (It didn’t hurt that we popped up on Good Morning America.)

From the beginning, the idea behind this pair of events — ringing the bell at the New York Stock Exchange and running the TCS New York City Marathon — was aimed at sending crucial messages. That recognizing climate change and building solutions is an obligation and an opportunity. That the energy industry understands this. That investors have good reason to support climate tech, one of the most exciting and fastest growing sectors. And, last but not least, that people’s perceptions of Houston as being all about oil and gas are simply wrong.

The dozens of us who gathered came from across the country and around the world, But by far, the largest contingent was from right here in Houston. Executives, engineers, entrepreneurs, and other innovators took part. People spearheading projects in every facet of energy, from wind to solar, carbon capture, and other methods of dramatically reducing carbon emissions. All as one team.

Those who traveled from “the energy capital” knew how important it was to highlight our Houston pride. As a new report from the Texas Climate Tech Collective points out, the biggest problem in the city’s climate tech ecosystem is its image. “Outsider perceptions of Houston often draw on negative stereotypes,” the report explains. “The number one disadvantage survey respondents chose – even more than access to VC capital – was Houston’s anti-climate reputation outside the state.”

It’s a problem I’ve been trying to combat for years, including through op-eds in national and international media outlets. Fortunately, the idea is starting to get through. Just days ago, the Financial Times reported that Houston claimed the top spot in this year’s FT-Nikkei Investing in America rankings by “moving beyond oil.” Our city, the paper said, “has become a hub for green energy innovation by building on its hydrocarbon past.”

Houston, and Texas a whole, should be immensely proud of this. But the energy industry has a long history of failing to tell its own stories. It’s time to change that. In fact, the recommendations in the collective’s report include “campaigning to improve Houston’s reputation, improving promotion of Houston’s energy transition initiatives and accomplishments, educating politicians and consumers, reversing anti-climate perception.”

Building bridges

All of the challenges we face, including the perception problem, will only be overcome if we work together. So the era of siloes must end. Climate change is an “all hands on deck” situation. This means companies large and small, as well as businesses focusing on all forms of energy, need to develop a “one-team” mentality.

We also need to step up our engagement with public sector entities. A great deal of public sector investment is being poured into renewable energy programs. Since I’ve served as an ambassador to the Department of Energy’s Equity in Energy initiative and a member of the National Petroleum Council, I’ve met many people in government who are eager to cooperate with us to help ensure that the United States leads the way in the energy transition.

The need for building these kinds of bridges is another reason that many of the participants in our Women & Allies in Energy team saw the New York City marathon as such a strong metaphor. It’s known for its bridges. And having run across all of them — and stopped for a quick selfie on the toughest one of all, the Queensboro Bridge — I’m reminded of their importance. I was happy to see that another recommendation in the collective’s report speaks directly to this. It calls for, “Building bridges between public and private, energy corporates and startups, universities and startups, and startups and mentors; seeking partnerships with other ecosystems; improving resources for early stage startups.”

We also need to build bridges among groups of people. More than ever, the industry needs diversity, equity and inclusion. (See my recent piece for Fast Company about why the C-Suite should double down, not shy away from, DEI.) We need to welcome people with all sorts of backgrounds, experiences, and perspectives. The greatest form of capital the energy sector has in building the future is not financial. It’s human capital. And the greatest natural resource we have is not one form of energy. It’s the people whose hard work, creativity, collaboration, and grit will get us to the finish line.

To help make all this happen, I’m calling for Houston to come together on climate change. Capitalizing on the annual Climate Week in New York City, and building on an event the City of Houston organized in 2021, let’s bring all industries and all people together next fall to show that we recognize climate reality, and are ready to take action together.

The next generation

While I did have the chance to lead the delegation at the NYSE closing bell, I did not hold the gavel — at least, not by myself. Instead, I handed it to my 12-year-old daughter, Ally. (Yes, her name is a big part of the inspiration behind our company name, ALLY Energy.)

As leaders in energy, we have to keep our eyes firmly focused on the next generation. This means not only giving them a strong supply of energy and healthier conditions on the planet. It also means giving them future job opportunities.

It’s up to us to build the pipeline for future talent. We need to improve STEAM (science, technology, engineering, arts and math) education. And we need to demonstrate to people who are currently underrepresented in our industry — such as women and members of minority groups — that they have a future in the world’s most exciting industry.

We can do this. We can get out of our bubble, show our Houston pride to the world, and lead the way to “energy 2.0” — an era of plentiful energy supplies and net-zero emissions. After all, dozens of us have returned from New York City with a mission: capitalize on all that momentum, join together as a team, and run the race to net zero.

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.

These 5 trailblazing Houston startups are leading the energy transition

meet the finalists

Houston is home to a growing number of startups reshaping what it means to be called the "Energy Capital of the World."

As part of the 2026 Houston Innovation Awards, our Energy Transition Business category honors those innovative startups that are providing solutions within renewables, climatetech, clean energy, alternative materials, circular economy and more.

Five clean energy startups have been named finalists for the 2026 award. The finalists, selected by our esteemed panel of judges, range from a lower-emission steel producer to a diagnostics platform developer working to support batteries used in data centers.

Read more about these innovative businesses, their initiatives, and their inspirational founders below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Capwell Services

Methane capture company Capwell Services works to eliminate vented oil and gas emissions economically for operators. 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.
