Gold H2, a Houston-based producer of clean hydrogen, is teaming up with a major U.S.-based oil and gas company as the first step in launching a 12-month series of pilot projects.

The tentative agreement with the unnamed oil and gas company kicks off the availability of the startup’s Black 2 Gold microbial technology. The technology underpins the startup’s biotech process for converting crude oil into proprietary Gold Hydrogen.

The cleantech startup plans to sign up several oil and gas companies for the pilot program. Gold H2 says it’s been in discussions with companies in North America, Latin America, India, Eastern Europe and the Middle East.

The pilot program is aimed at demonstrating how Gold H2’s technology can transform old oil wells into hydrogen-generating assets. Gold H2, a spinout of Houston-based biotech company Cemvita, says the technology is capable of producing hydrogen that’s cheaper and cleaner than ever before.

“This business model will reshape the traditional oil and gas industry landscape by further accelerating the clean energy transition and creating new economic opportunities in areas that were previously dismissed as unviable,” Gold H2 says in a news release.

The start of the Black 2 Gold demonstrations follows the recent hiring of oil and gas industry veteran Prabhdeep Singh Sekhon as CEO.

“With the proliferation of AI, growth of data centers, and a national boom in industrial manufacturing underway, affordable … carbon-free energy is more paramount than ever,” says Rayyan Islam, co-founder and general partner at venture capital firm 8090 Industries, an investor in Gold H2. “We’re investing in Gold H2, as we know they’ll play a pivotal role in unleashing a new dawn for energy abundance in partnership with the oil industry.”

ExxonMobil extends European fuel cell pilot project

next step

The Esso fuel business of Spring-based ExxonMobil is forging ahead with a pilot project at its Dutch refinery in Rotterdam to test technology aimed at reducing carbon emissions and simultaneously generating electricity and hydrogen.

The pilot project is a cornerstone of an extended agreement between ExxonMobil Technology and Engineering and Danbury, Connecticut-based clean energy company FuelCell Energy. The deal is now set to expire at the end of 2026.

ExxonMobil and FuelCell announced the pilot project in 2023.

“The unique advantage of this technology is that it not only captures CO2 but also produces low-carbon power, heat, and hydrogen as co-products,” Geoff Richardson, senior vice president of ExxonMobil Low Carbon Solutions, said last year.

The Rotterdam facility, which opened in 1960, will be the first location in the world to test the technology. The technology eventually could be rolled out at additional ExxonMobil sites.

The European Union is among the funders of the pilot project. FuelCell is making carbonate fuel cells for the project at its manufacturing plant in Torrington, Connecticut.

The extended agreement enables FuelCell to incorporate elements of the jointly developed technology into carbon capture products currently being marketed to customers. ExxonMobil and FuelCell are working on formalizing an arrangement for selling the new technology.

“The technology, which captures carbon while simultaneously generating electricity and hydrogen, could improve the economics of carbon capture and could potentially lower the barrier to broader adoption of carbon capture in the marketplace,” according to a FuelCell news release.

FuelCell says its 10-year partnership with ExxonMobil has focused on developing technology that reduces carbon emissions from emission-intensive sectors while generating electricity and hydrogen in the process — “something that no other fuel cell technology or conventional absorption systems can do.”

Houston-based geothermal energy startup releases promising results of Texas pilot

hot off the press

As it seeks an additional $30 million in series A funding, Houston startup Sage Geosystems has released promising results from a test of its technology for underground storage of geothermal energy.

Sage says the pilot project, conducted at a Shell-drilled oil well in the Rio Grande Valley’s Starr County, showed the company’s long-term energy storage can compete on a cost basis with lithium-ion battery storage, hydropower storage, and natural gas-powered peaker plants. Peaker plants supply power during periods of peak energy demand.

Furthermore, Sage’s geothermal technology will provide more power capacity at half the cost of other advanced geothermal systems, the company says.

Sage’s storage system retrofits oil and gas wells with the company’s geothermal technology. But the company says its technology “can be deployed virtually anywhere.”

The system relies on mechanical storage instead of battery storage. In mechanical storage, heat, water, or air works in tandem with compressors, turbines, and other machinery. By contrast, battery storage depends on chemistry to get the job done.

“We have cracked the code to provide the perfect complement to renewable energy. … The opportunities for our energy storage to provide power are significant — from remote mining operations to data centers to solving energy poverty in remote locations,” former Shell executive Cindy Taff, CEO of Sage, says in a September 12 news release.

Sage says its storage capacity can be connected to existing power grids, or it can develop microgrids that harness stored energy.

An August 2023 article in The New York Times explained that Sage “is pursuing fracked wells that act as batteries. When there’s surplus electricity on the grid, water gets pumped into the well. In times of need, pressure and heat in the fractures pushes water back up, delivering energy.”

The pilot project, a joint venture between Sage and the Bureau of Economic Ecology at the University of Texas at Austin, was performed as part of a feasibility study financed by the Air Force. Now that the test results are in, Sage plans to build a prototype geothermal project at the Air Force’s Ellington Field Joint Reserve Base in Houston.

Sage says another feasibility study is underway in the Middle East in partnership with an unnamed oil and gas company.

Founded in 2020, Sage plans to raise another $30 million to accompany its previous series A funding.

The Virya climate fund and Houston-based drilling contractor Nabors Industries helped finance the pilot project in Starr County.

Last year, Sage announced it received an undisclosed amount of equity from Houston-based Ignis H2 Energy, a geothermal exploration and development company, and Dutch energy company Geolog International. Also last year, Sage said Nabors and Virya had teamed up for a $12 million investment in the startup.

What EPA’s carbon capture and storage permitting announcement means for Texas

The View From HETI

Earlier this month, Texas was granted authority by the federal government for permitting carbon capture and storage (CCS) projects. This move could help the U.S. cut emissions while staying competitive in the global energy game.

In June, the U.S. Environmental Protection Agency (EPA) proposed approving Texas’ request for permitting authority under the Safe Drinking Water Act (SDWA) for Class VI underground injection wells for carbon capture and storage (CCS) in the state under a process called “primacy.” The State of Texas already has permitting authority for other injection wells (Classes I-V). In November, the EPA announced final approval of Texas’ primacy request.

Why This Matters for Texas

Texas is the headquarters for virtually every segment of the energy industry. According to the U.S. Energy Information Administration, Texas is the top crude oil- and natural-gas producing state in the nation. The state has more crude oil refineries and refining capacity than any other state in the nation. Texas produces more electricity than any other state, and the demand for electricity will grow with the development of data centers and artificial intelligence (AI). Simply put, Texas is the backbone of the nation’s energy security and competitiveness. For the nation’s economic competitiveness, it is important that Texas continue to produce more energy with less emissions. CCS is widely regarded as necessary to continue to lower the emissions intensity of the U.S. industrial sector for critical products including power generation, refining, chemicals, steel, cement and other products that our country and world demand.

The Greater Houston Partnership’s Houston Energy Transition Initiative (HETI) has supported efforts to bring CCUS to a broader commercial scale since the initiative’s inception.

“Texas is uniquely positioned to deploy CCUS at scale, with world-class geology, a skilled workforce, and strong infrastructure. We applaud the EPA for granting Texas the authority to permit wells for CCUS, which we believe will result in safe and efficient permitting while advancing technologies that strengthen Texas’ leadership in the global energy market,” said Jane Stricker, Executive Director of HETI and Senior Vice President, Energy Transition at the Greater Houston Partnership.

What is Primacy, and Why is it Important?

Primacy grants permitting authority for Class VI wells for CCS to the Texas Railroad Commission instead of the EPA. Texas is required to follow the same strict standards the EPA uses. The EPA has reviewed Texas’ application and determined it meets those requirements.

Research suggests that Texas has strong geological formations for CO2 storage, a world-class, highly skilled workforce, and robust infrastructure primed for the deployment of CCS. However, federal permitting delays are stalling billions of dollars of private sector investment. There are currently 257 applications under review, nearly one-quarter of which are located in Texas, with some applications surpassing the EPA’s target review period of 24 months. This creates uncertainty for developers and investors and keeps thousands of potential jobs out of reach. By transferring permitting to the state, Texas will apply local resources to issue Class VI permits across the states in a timely manner.

Texas joins North Dakota, Wyoming, Louisiana, West Virginia and Arizona with the authority for regulating Class VI wells.

Is CCS safe?

A 2025 study by Texas A&M University reviewed operational history and academic literature on CCS in the United States. The study analyzed common concerns related to CCS efficacy and safety and found that CCS reduces pollutants including carbon dioxide, particulate matter, sulfur oxides and nitrogen oxides. The research found that the risks of CCS present a low probability of impacting human life and can be effectively managed through existing state and federal regulations and technical monitoring and safety protocols.

What’s Next?

The final rule granting Texas’ primacy will become effective 30 days after publication in the Federal Register. Once in effect, the Texas Railroad Commission will be responsible for permitting wells for carbon capture, use and storage and enforcing their safe operation.

Houston energy expert: How the U.S. can turn carbon into growth

Guets Column

For the past 40 years, climate policy has often felt like two steps forward, one step back. Regulations shift with politics, incentives get diluted, and long-term aspirations like net-zero by 2050 seem increasingly out of reach. Yet greenhouse gases continue to rise, and the challenges they pose are not going away.

This matters because the costs are real. Extreme weather is already straining U.S. power grids, damaging homes, and disrupting supply chains. Communities are spending more on recovery while businesses face rising risks to operations and assets. So, how can the U.S. prepare and respond?

The Baker Institute Center for Energy Studies (CES) points to two complementary strategies. First, invest in large-scale public adaptation to protect communities and infrastructure. Second, reframe carbon as a resource, not just a waste stream to be reduced.

Why Focusing on Emissions Alone Falls Short

Peter Hartley argues that decades of global efforts to curb emissions have done little to slow the rise of CO₂. International cooperation is difficult, the costs are felt immediately, and the technologies needed are often expensive. Emissions reduction has been the central policy tool for decades, and it has been neither sufficient nor effective.

One practical response is adaptation, which means preparing for climate impacts we can’t avoid. Some of these measures are private, taken by households or businesses to reduce their own risks, such as farmers shifting crop types, property owners installing fire-resistant materials, or families improving insulation. Others are public goods that require policy action. These include building stronger levees and flood defenses, reinforcing power grids, upgrading water systems, revising building codes, and planning for wildfire risks. Such efforts protect people today while reducing long-term costs, and they work regardless of the source of extreme weather. Adaptation also does not depend on global consensus; each country, state, or city can act in its own interest. Many of these measures even deliver benefits beyond weather resilience, such as stronger infrastructure and improved security against broader threats.

McKinsey research reinforces this logic. Without a rapid scale-up of climate adaptation, the U.S. will face serious socioeconomic risks. These include damage to infrastructure and property from storms, floods, and heat waves, as well as greater stress on vulnerable populations and disrupted supply chains.

Making Carbon Work for Us

While adaptation addresses immediate risks, Ken Medlock points to a longer-term opportunity: turning carbon into value.

Carbon can serve as a building block for advanced materials in construction, transportation, power transmission, and agriculture. Biochar to improve soils, carbon composites for stronger and lighter products, and next-generation fuels are all examples. As Ken points out, carbon-to-value strategies can extend into construction and infrastructure. Beyond creating new markets, carbon conversion could deliver lighter and more resilient materials, helping the U.S. build infrastructure that is stronger, longer-lasting, and better able to withstand climate stress.

A carbon-to-value economy can help the U.S. strengthen its manufacturing base and position itself as a global supplier of advanced materials.

These solutions are not yet economic at scale, but smart policies can change that. Expanding the 45Q tax credit to cover carbon use in materials, funding research at DOE labs and universities, and supporting early markets would help create the conditions for growth.

Conclusion

Instead of choosing between “doing nothing” and “net zero at any cost,” we need a third approach that invests in both climate resilience and carbon conversion.

Public adaptation strengthens and improves the infrastructure we rely on every day, including levees, power grids, water systems, and building standards that protect communities from climate shocks. Carbon-to-value strategies can complement these efforts by creating lighter, more resilient carbon-based infrastructure.

CES suggests this combination is a pragmatic way forward. As Peter emphasizes, adaptation works because it is in each nation’s self-interest. And as Ken reminds us, “The U.S. has a comparative advantage in carbon. Leveraging it to its fullest extent puts the U.S. in a position of strength now and well into the future.”
