The federal government has canceled more than $700 million in funding for three clean energy projects in the Houston area.

In all, the U.S. Department of Energy (DOE) recently wiped out $3.7 billion in funding for 24 carbon capture and decarbonization projects across the country.

Houston-area projects that took a hit are:

It’s unclear how the loss of federal funding will affect the three Houston-area projects.

All $3.7 billion from the DOE was awarded in 2024 and 2025 during the Biden administration—in some cases days before President Trump took office.

“While the previous administration failed to conduct a thorough financial review before signing away billions of taxpayer dollars, the Trump administration is doing our due diligence to ensure we are utilizing taxpayer dollars to strengthen our national security, bolster affordable, reliable energy sources, and advance projects that generate the highest possible return on investment,” U.S. Energy Secretary Chris Wright said in a release.

Advocates for clean energy sharply criticized the DOE’s action:

  • Jessie Stolark, executive director of the Carbon Capture Coalition, said cancellation of the 24 DOE-funded projects “is a major step backward in the nationwide deployment of carbon management technologies. It is hugely disappointing to see these projects canceled — projects that had already progressed through a rigorous, months-long review process by technical experts at DOE.”
  • Iliana Paul, deputy director for the Sierra Club’s industrial transformation campaign, complained that the Trump administration “killed dozens of major investments in American competitiveness, good jobs, and cleaner air to support Trump’s tax cuts and line the pockets of billionaires. These projects were not just pro-climate; they were pro-jobs, pro-innovation, and pro-public health. American workers, fenceline communities, and forward-thinking companies have had the rug pulled out from under them.”
  • Conrad Schneider, senior U.S. director of the Clean Air Taskforce, said the DOE’s move “is bad for U.S. competitiveness in the global market and also directly contradictory to the administration’s stated goals of supporting energy production and environmental innovation. Canceling cutting-edge technology demonstrations, including support for carbon capture and storage projects, undercuts U.S. competitiveness at a time when there is a growing global market for cleaner industrial products and technologies.”

Houston joint venture secures $5.2M for AI-powered methane tracking tech

fresh funds

Houston-based Envana Software Solutions has received more than $5.2 million in federal and non-federal funding to support the development of technology for the oil and gas sector to monitor and reduce methane emissions.

Thanks to the work backed by the new funding, Envana says its suite of emissions management software will become the industry's first technology to allow an oil and gas company to obtain a full inventory of greenhouse gases.

The funding comes from a more than $4.2 million grant from the U.S. Department of Energy (DOE) and more than $1 million in non-federal funding.

“Methane is many times more potent than carbon dioxide and is responsible for approximately one-third of the warming from greenhouse gases occurring today,” Brad Crabtree, assistant secretary at DOE, said in 2024.

With the funding, Envana will expand artificial intelligence (AI) and physics-based models to help detect and track methane emissions at oil and gas facilities.

“We’re excited to strengthen our position as a leader in emissions and carbon management by integrating critical scientific and operational capabilities. These advancements will empower operators to achieve their methane mitigation targets, fulfill their sustainability objectives, and uphold their ESG commitments with greater efficiency and impact,” says Nagaraj Srinivasan, co-lead director of Envana.

In conjunction with this newly funded project, Envana will team up with universities and industry associations in Texas to:

  • Advance work on the mitigation of methane emissions
  • Set up internship programs
  • Boost workforce development
  • Promote environmental causes

Envana, a software-as-a-service (SaaS) startup, provides emissions management technology to forecast, track, measure and report industrial data for greenhouse gas emissions.

Founded in 2023, Envana is a joint venture between Houston-based Halliburton, a provider of products and services for the energy industry, and New York City-based Siguler Guff, a private equity firm. Siguler Gulf maintains an office in Houston.

“Envana provides breakthrough SaaS emissions management solutions and is the latest example of how innovation adds to sustainability in the oil and gas industry,” Rami Yassine, a senior vice president at Halliburton, said when the joint venture was announced.

Houston's hydrogen revolution gets up to $1.2B federal boost to power Gulf Coast’s clean energy future

HyVelocity funding

The emerging low-carbon hydrogen ecosystem in Houston and along the Texas Gulf Coast is getting as much as a $1.2 billion lift from the federal government.

The U.S. Department of Energy funding, announced November 20, is earmarked for the new HyVelocity Hub. The hub — backed by energy companies, schools, nonprofits, and other organizations — will serve the country’s biggest hydrogen-producing area. The region earns that status thanks to more than 1,000 miles of dedicated hydrogen pipelines and almost 50 hydrogen production plants.

“The HyVelocity Hub demonstrates the power of collaboration in catalyzing economic growth and creating value for communities as we build a regional hydrogen economy that delivers benefits to Gulf Coast communities,” says Paula Gant, president and CEO of Des Plaines, Illinois-based GTI Energy, which is administering the hub.

HyVelocity, which aims to become the largest hydrogen hub in the country, has already received about $22 million of the $1.2 billion in federal funding to kickstart the project.

Organizers of the hydrogen project include:

  • Arlington, Virginia-based AES Corp.
  • Air Liquide, whose U.S. headquarters is in Houston
  • Chevron, which is moving its headquarters to Houston
  • Spring-based ExxonMobil
  • Lake Mary, Florida-based Mitsubishi Power Americas
  • Denmark-based Ørsted
  • Center for Houston’s Future
  • Houston Advanced Research Center
  • University of Texas at Austin

The hub’s primary contractor is HyVelocity LLC. The company says the hub could reduce carbon dioxide emissions by up to seven million metric tons per year and create as many as 45,000 over the life of the project.

HyVelocity is looking at several locations in the Houston area and along the Gulf Coast for large-scale production of hydrogen. The process will rely on water from electrolysis along with natural gas from carbon capture and storage. To improve distribution and lower storage costs, the hub envisions creating a hydrogen pipeline system.

Clean hydrogen generated by the hub will help power fuel-cell electric trucks, factories, ammonia plants, refineries, petrochemical facilities, and marine fuel operations.

DOE dishes out funding to 2 Houston carbon caption projects

ccus news

Two Houston companies have received federal funding to develop carbon capture and storage projects.

Evergreen Sequestration Hub LLC, a partnership of Houston-based Trace Carbon Solutions and Jacksonville, Mississippi-based Molpus Woodlands Group, got more than $27.8 million from the U.S. Department of Energy for its Evergreen Sequestration Hub project in Louisiana. DOE says the project is valued at $34.8 million.

The hub will be built on about 20,000 acres of timberland in Louisiana’s Calcasieu and Beauregard parishes for an unidentified customer. It’ll be capable of storing about 250 million metric tons of carbon dioxide.

Trace Carbon Solutions, a subsidiary of Trace Midstream Partners, is developing CCS assets and supporting midstream infrastructure across North America. Molpus, an investment advisory firm, buys, manages, and sells timberland as an investment vehicle for pension funds, college endowments, foundations, insurance companies, and high-net-worth investors.

Another Houston company, RPS Expansion LLC, has received $9 million from the DOE to expand the River Parish Sequestration Project. Following the expansion, the project will be able to store up to 384 million metric tons of carbon dioxide. The CCUS hub is between Baton Rouge and New Orleans.

DOE says the River Parish expansion is valued at $11.8 million.

Also receiving DOE funding is a CCUS project to be developed off the coast of Corpus Christi. The developer is the Southern States Energy Board, based in Peachtree Corners, Georgia.

DOE is chipping in more than $51.1 million for the nearly $64 million hub. It’s estimated that about 35 million metric tons of carbon dioxide emissions are released each year from about 50 industrial and power facilities within a 100-mile radius of Mustang Island. Port Aransas is located on the 18-mile-long island.

In all, DOE recently allocated $518 million to 23 CCUS projects in the U.S.

“The funding … will help ensure that carbon storage projects — crucial to slashing harmful carbon pollution — are designed, built, and operated safely and responsibly across all phases of development to deliver healthier communities as well as high-quality American jobs,” Brad Crabtree, assistant DOE secretary for fossil energy and carbon management, says in a news release.

Carbon removal industry calls on U.S. government for regulation in new industry report

by the numbers

The unregulated carbon dioxide removal industry is calling on the U.S. government to implement standards and regulations to boost transparency and confidence in the sector that's been flooded with billions of dollars in federal funding and private investment.

A report Wednesday by the Carbon Removal Alliance, a nonprofit representing the industry, outlined recommendations to improve monitoring, reporting, and verification. Currently the only regulations in the U.S. are related to safety of these projects. Some of the biggest industry players, including Heirloom and Climeworks, are alliance members.

“I think it’s rare for an industry to call for regulation of itself and I think that is a signal of why this is so important,” said Giana Amador, executive director of the alliance. Amador said monitoring, reporting and verification are like “climate receipts” that confirm the amount of carbon removed as well as how long it can actually be stored underground.

Without federal regulation, she said “it really hurts competition and it forces these companies into sort of a marketing arms race instead of being able to focus their efforts on making sure that there really is a demonstrable climate impact.”

The nonprofit defines carbon removal as any solution that captures carbon dioxide from the atmosphere and stores it permanently. One of the most popular technologies is direct air capture, which filters air, extracts carbon dioxide and puts it underground.

The Inflation Reduction Act and the Bipartisan Infrastructure Law have provided around $12 billion for carbon management projects in the U.S. Some of this funding supports the development of four Regional Direct Air Capture Hubs at commercial scale that will capture at least 1 million tons of carbon dioxide annually. Two hubs are slated to be built in Texas and Louisiana.

Some climate scientists say direct air capture is too expensive, far from being scaled and can be used as an excuse by the oil and gas industry to keep polluting.

Gernot Wagner, a climate economist at Columbia Business School at Columbia University, said this is the “moral hazard” of direct air capture — removing carbon from the atmosphere could be utilized by the oil and gas industry to continue polluting.

“It does not mean that the underlying technology is not a good thing,” said Wagner. Direct air capture “decreases emissions, but in the long run also extends the life of any one particular coal plant or gas plant.”

In 2023, Occidental Petroleum Corporation purchased the direct air capture company, Carbon Engineering Ltd, for $1.1 billion. In a news release, Occidental CEO Vicki Hollub said, “Together, Occidental and Carbon Engineering can accelerate plans to globally deploy (the) technology at a climate-relevant scale and make (it) the preferred solution for businesses seeking to remove their hard-to-abate emissions.”

Jonathan Foley, executive director of Project Drawdown, doesn't consider carbon dioxide removal technologies to be a true climate solution.

“I do welcome at least some interventions from the federal government to monitor and verify and evaluate the performance of these proposed carbon removal schemes, because it’s kind of the Wild West out there,” said Foley.

“But considering it can cost ten to 100 times more to try to remove a ton of carbon rather than prevent it, how is that even remotely conscionable to spend public dollars on this kind of stuff?” he said.

Katharine Hayhoe, chief scientist of The Nature Conservancy and a distinguished professor at Texas Tech University, said standards for the direct carbon capture industry “are very badly needed” because of the level of government subsidies and private investment. She said there's no single fix for the climate crisis, and many strategies are needed.

Hayhoe said these include improving the efficiency of energy systems, transitioning to clean energy, weaning the world off fossil fuels and maintaining healthy ecosystems to trap carbon dioxide. On the other hand, she said, carbon removal technologies are “very high hanging fruit.”

"It takes a lot of money and a lot of energy to get to the top of the tree. That’s the carbon capture solution,” said Hayhoe. “Of course we need every fruit on the tree. But doesn’t it make sense to pick up the fruit on the ground, to prioritize that?”

Other climate scientists are entirely opposed to this technology.

“It should be banned,” said Mark Z. Jacobson, professor of civil and environmental engineering at Stanford University.

Carbon removal technologies indirectly increase the amount of carbon dioxide in the atmosphere, Jacobson said. The reason, he said, is that even in cases where direct air capture facilities are powered by renewable energy, the clean energy is being used for carbon removal instead of replacing a fossil fuel source.

“When you just look at the capture equipment, you get a (carbon) reduction," Jacobson said. "But when you look at the bigger system, you’re increasing.”

New report maps Houston workforce development strategies as companies transition to cleaner energy

to-do list

The University of Houston’s Energy University latest study with UH’s Division of Energy and Innovation with stakeholders from the energy industry, academia have released findings from a collaborative white paper, titled "Workforce Development for the Future of Energy.”

UH Energy’s workforce analysis found that the greatest workforce gains occur with an “all-of-the-above” strategy to address the global shift towards low-carbon energy solutions. This would balance electrification and increased attention to renewables with liquid fuels, biomass, hydrogen, carbon capture, utilization and storage commonly known as CCUS, and carbon dioxide removal, according to a news release.

The authors of the paper believe this would support economic and employment growth, which would leverage workers from traditional energy sectors that may lose jobs during the transition.

The emerging hydrogen ecosystem is expected to create about 180,000 new jobs in the greater Houston area, which will offer an average annual income of approximately $75,000. Currently, 40 percent of Houston’s employment is tied to the energy sector.

“To sustain the Houston region’s growth, it’s important that we broaden workforce participation and opportunities,” Ramanan Krishnamoorti, vice president of energy and innovation at UH, says in a news release. “Ensuring workforce readiness for new energy jobs and making sure we include disadvantaged communities is crucial.”

Some of the key takeaways include strategies that include partnering for success, hands-on training programs, flexible education pathways, comprehensive support services, and early and ongoing outreach initiatives.

“The greater Houston area’s journey towards a low-carbon future is both a challenge and an opportunity,” Krishnamoorti continues. “The region’s ability to adapt and lead in this new era will depend on its commitment to collaboration, innovation, and inclusivity. By preparing its workforce, engaging its communities, and leveraging its industrial heritage, we can redefine our region and continue to thrive as a global energy leader.”

The study was backed by federal funding from the Department of the Treasury through the State of Texas under the Resources and Ecosystems Sustainability, Tourist Opportunities, and Revived Economies of the Gulf Coast States Act of 2012.

UH researchers make breakthrough in cutting carbon capture costs

Carbon breakthrough

A team of researchers at the University of Houston has made two breakthroughs in addressing climate change and potentially reducing the cost of capturing harmful emissions from power plants.

Led by Professor Mim Rahimi at UH’s Cullen College of Engineering, the team released two significant publications that made significant strides relating to carbon capture processes. The first, published in Nature Communications, introduced a membraneless electrochemical process that cuts energy requirements and costs for amine-based carbon dioxide capture during the acid gas sweetening process. Another, featured on the cover of ES&T Engineering, demonstrated a vanadium redox flow system capable of both capturing carbon and storing renewable energy.

“These publications reflect our group’s commitment to fundamental electrochemical innovation and real-world applicability,” Rahimi said in a news release. “From membraneless systems to scalable flow systems, we’re charting pathways to decarbonize hard-to-abate sectors and support the transition to a low-carbon economy.”

According to the researchers, the “A Membraneless Electrochemically Mediated Amine Regeneration for Carbon Capture” research paper marked the beginning of the team’s first focus. The research examined the replacement of costly ion-exchange membranes with gas diffusion electrodes. They found that the membranes were the most expensive part of the system, and they were also a major cause of performance issues and high maintenance costs.

The researchers achieved more than 90 percent CO2 removal (nearly 50 percent more than traditional approaches) by engineering the gas diffusion electrodes. According to PhD student and co-author of the paper Ahmad Hassan, the capture costs approximately $70 per metric ton of CO2, which is competitive with other innovative scrubbing techniques.

“By removing the membrane and the associated hardware, we’ve streamlined the EMAR workflow and dramatically cut energy use,” Hassan said in the news release. “This opens the door to retrofitting existing industrial exhaust systems with a compact, low-cost carbon capture module.”

The second breakthrough, published by PhD student Mohsen Afshari, displayed a reversible flow battery architecture that absorbs CO2 during charging and releases it upon discharge. The results suggested that the technology could potentially provide carbon removal and grid balancing when used with intermittent renewables, such as solar or wind power.

“Integrating carbon capture directly into a redox flow battery lets us tackle two challenges in one device,” Afshari said in the release. “Our front-cover feature highlights its potential to smooth out renewable generation while sequestering CO2.”

As electric bills rise, evidence mounts that data centers share blame

Data Talk

Amid rising electric bills, states are under pressure to insulate regular household and business ratepayers from the costs of feeding Big Tech's energy-hungry data centers.

It's not clear that any state has a solution and the actual effect of data centers on electricity bills is difficult to pin down. Some critics question whether states have the spine to take a hard line against tech behemoths like Microsoft, Google, Amazon and Meta.

But more than a dozen states have begun taking steps as data centers drive a rapid build-out of power plants and transmission lines.

That has meant pressuring the nation's biggest power grid operator to clamp down on price increases, studying the effect of data centers on electricity bills or pushing data center owners to pay a larger share of local transmission costs.

Rising power bills are “something legislators have been hearing a lot about. It’s something we’ve been hearing a lot about. More people are speaking out at the public utility commission in the past year than I’ve ever seen before,” said Charlotte Shuff of the Oregon Citizens’ Utility Board, a consumer advocacy group. “There’s a massive outcry.”

Not the typical electric customer

Some data centers could require more electricity than cities the size of Pittsburgh, Cleveland or New Orleans, and make huge factories look tiny by comparison. That's pushing policymakers to rethink a system that, historically, has spread transmission costs among classes of consumers that are proportional to electricity use.

“A lot of this infrastructure, billions of dollars of it, is being built just for a few customers and a few facilities and these happen to be the wealthiest companies in the world,” said Ari Peskoe, who directs the Electricity Law Initiative at Harvard University. “I think some of the fundamental assumptions behind all this just kind of breaks down.”

A fix, Peskoe said, is a “can of worms" that pits ratepayer classes against one another.

Some officials downplay the role of data centers in pushing up electric bills.

Tricia Pridemore, who sits on Georgia’s Public Service Commission and is president of the National Association of Regulatory Utility Commissioners, pointed to an already tightened electricity supply and increasing costs for power lines, utility poles, transformers and generators as utilities replace aging equipment or harden it against extreme weather.

The data centers needed to accommodate the artificial intelligence boom are still in the regulatory planning stages, Pridemore said, and the Data Center Coalition, which represents Big Tech firms and data center developers, has said its members are committed to paying their fair share.

But growing evidence suggests that the electricity bills of some Americans are rising to subsidize the massive energy needs of Big Tech as the U.S. competes in a race against China for artificial intelligence superiority.

Data and analytics firm Wood Mackenzie published a report in recent weeks that suggested 20 proposed or effective specialized rates for data centers in 16 states it studied aren’t nearly enough to cover the cost of a new natural gas power plant.

In other words, unless utilities negotiate higher specialized rates, other ratepayer classes — residential, commercial and industrial — are likely paying for data center power needs.

Meanwhile, Monitoring Analytics, the independent market watchdog for the mid-Atlantic grid, produced research in June showing that 70% — or $9.3 billion — of last year's increased electricity cost was the result of data center demand.

States are responding

Last year, five governors led by Pennsylvania's Josh Shapiro began pushing back against power prices set by the mid-Atlantic grid operator, PJM Interconnection, after that amount spiked nearly sevenfold. They warned of customers “paying billions more than is necessary.”

PJM has yet to propose ways to guarantee that data centers pay their freight, but Monitoring Analytics is floating the idea that data centers should be required to procure their own power.

In a filing last month, it said that would avoid a "massive wealth transfer” from average people to tech companies.

At least a dozen states are eyeing ways to make data centers pay higher local transmission costs.

In Oregon, a data center hot spot, lawmakers passed legislation in June ordering state utility regulators to develop new — presumably higher — power rates for data centers.

The Oregon Citizens’ Utility Board says there is clear evidence that costs to serve data centers are being spread across all customers — at a time when some electric bills there are up 50% over the past four years and utilities are disconnecting more people than ever.

New Jersey’s governor signed legislation last month commissioning state utility regulators to study whether ratepayers are being hit with “unreasonable rate increases” to connect data centers and to develop a specialized rate to charge data centers.

In some other states, like Texas and Utah, governors and lawmakers are trying to avoid a supply-and-demand crisis that leaves ratepayers on the hook — or in the dark.

Doubts about states protecting ratepayers

In Indiana, state utility regulators approved a settlement between Indiana Michigan Power Co., Amazon, Google, Microsoft and consumer advocates that set parameters for data center payments for service.

Kerwin Olsen, of the Citizens Action Council of Indiana, a consumer advocacy group, signed the settlement and called it a “pretty good deal” that contained more consumer protections than what state lawmakers passed.

But, he said, state law doesn't force large power users like data centers to publicly reveal their electric usage, so pinning down whether they're paying their fair share of transmission costs "will be a challenge.”

In a March report, the Environmental and Energy Law Program at Harvard University questioned the motivation of utilities and regulators to shield ratepayers from footing the cost of electricity for data centers.

Both utilities and states have incentives to attract big customers like data centers, it said.

To do it, utilities — which must get their rates approved by regulators — can offer “special deals to favored customers” like a data center and effectively shift the costs of those discounts to regular ratepayers, the authors wrote. Many state laws can shield disclosure of those rates, they said.

In Pennsylvania, an emerging data center hot spot, the state utility commission is drafting a model rate structure for utilities to consider adopting. An overarching goal is to get data center developers to put their money where their mouth is.

“We’re talking about real transmission upgrades, potentially hundreds of millions of dollars,” commission chairman Stephen DeFrank said. “And that’s what you don’t want the ratepayer to get stuck paying for."
