Houston microgrid company scores $2.1M grant for hydrogen blending tech research

fresh funding

A Houston-based provider of electric microgrids has scooped up a $2.1 million grant from the California Energy Commission for development of technology aimed at reducing greenhouse gasses and other natural gas emissions.

Enchanted Rock shares the grant with the University of California Riverside, or UCR.

“This is an exciting opportunity to further advance the potential use of hydrogen fuel blends for commercialization and market adoption,” Thomas McAndrew, founder and CEO of Enchanted Rock, says in a news release. “We believe in using the cleanest fuel available without compromising on reliability or performance for our customers and are dedicated to helping California, and the nation, achieve its climate and energy goals.”

The use of a hydrogen and natural gas blend for fueling generators shows promise for reducing emissions and improving efficiency, according to Enchanted Rock. The company says the funding will enable it to identify the ideal blend of natural gas and hydrogen for operating a natural generator while improving performance and minimizing emissions.

As part of the grant, UCR’s College of Engineering-Center for Environmental Research and Technology (CE-CERT) will play a key role in measuring emissions and combustion performance. Meanwhile, Palomar College in San Marcos, California, will host a field demonstration site.

”Hydrogen is one of the ‘low-hanging fruit’ solutions to decarbonize our transportation system and other sectors where emissions are hard to abate, and it can serve as a zero-carbon green fuel for internal combustion off-road and highway engines,” says UCR professor Georgios Karavalakis.

Founded in 2006, Enchanted Rock specializes in electrical-resiliency-as-a-service for sectors such as health care, manufacturing, and government infrastructure. The company’s dual-purpose microgrids rely on natural gas and renewable natural gas to produce lower carbon emissions and air pollutants than diesel generators.

In December, Enchanted Rock said it had teamed up with U.S. Energy to supply renewable natural gas for Microsoft’s new data center in San Jose, California, during grid outages and when businesses are directed to reduce power usage.

sustainable support

Microsoft is one step closer to its goals of being carbon negative by 2030 thanks to a new initiative involving a Houston energy company.

Houston-based Enchanted Rock has teamed up to provide its electrical resiliency-as-a-service and ultra-low-emission generators to Microsoft’s new data center in San Jose, California.

Along with Wisconsin-based U.S. Energy, a vertically integrated energy solutions provider, the partnership will procure renewable natural gas for the data center during grid outages and when California’s Base Interruptible Power is activated. Previously, Microsoft announced its plans for carbon neutrality by 2030.

“Enchanted Rock has always been committed to using the cleanest fuel available without compromising on reliability for our customers,” Thomas McAndrew, founder and CEO of Enchanted Rock, says in a news release. “After announcing our renewable natural gas solution in 2021 and this particular Microsoft data center project in 2022, we’re proud to be taking this important next step toward seeing this key technology in operation."

Enchanted Rock, founded in 2006, provides microgrid technology that use natural gas and renewable natural gas, providing for lower emissions and pollution than diesel generators. The company also provides a software platform, GraniteEcosystem, for users for constant management, analytics, and more.

The RNG for the will be delivered by U.S. Energy and sourced from diverted food waste. Per the release, the agreement allows for flexibility in the amount of RNG supplied, which is scheduled to begin being procured by early 2026, so that the initiative will meet its evolving standards for emissions reduction.

“Energy resilience is crucial with data centers like this one,” president of U.S. Energy, Mike Koel, says in the release. “Through our portfolio of 40 renewable natural gas projects, we’re able to ensure our customers have the supply needed to meet any additionality requirements. As we continue to grow our portfolio, our partnership with Enchanted Rock will help more organizations take that next step in their carbon reduction goals.”

ENGIE strikes clean energy deal with Houston biomanufacturer

energy match

ENGIE North America has signed an agreement with Aker BioMarine to supply around-the-clock, Texas-sourced clean energy to the Norwegian company's Houston manufacturing facility.

The deal is through ENGIE's 24/7 offering, which allows users to "match electricity consumption with local renewable generation on an hourly basis," rather than annual renewable energy matching, according to a news release.

Houston-based ENGIE NA will match 90% of Aker BioMarine's hourly electricity consumption at its Houston facility through renewable energy certificates that link electricity consumed to clean power generated. The renewable energy will be sourced largely from ENGIE's Impact Solar Project in Lamar County, Texas.

“Working with companies that have made sustainability a core part of their strategy is essential to delivering meaningful progress,” Taymur Bunkheila, regional VP and retail supply lead for ENGIE’s U.S. 24/7 product, said in the release. “By aligning energy solutions with operational needs, we can help organizations improve transparency, strengthen accountability, and deliver measurable outcomes. This agreement demonstrates how companies can take practical steps today while building toward long-term sustainability objectives.”

Aker BioMarine, which develops sustainable marine-based ingredients, processes the majority of its krill and algae products at its Houston facility. The company says the deal with ENGIE marks an important step in reducing the environmental footprint of its operations.

“Through this agreement, we expect to reduce our Scope 2 emissions, marking an important milestone in our broader sustainability journey,” Matts Johansen, CEO at Aker BioMarine, added in the release. “ENGIE has delivered an affordable, innovative and transparent solution that allows us to match our electricity consumption for our Houston manufacturing facility with renewable power generation. The transparent data ENGIE provides strengthens our climate reporting while helping us continue delivering high-quality products with a lower environmental footprint."

ENGIE has more than 11 gigawatts of renewable energy projects in operation or under construction in the U.S. and Canada. The company is targeting 95 gigawatts by 2030

ExxonMobil announces date to move legal headquarters to Texas

save the date

Energy giant Exxon Mobil Corp. has set a date to move its legal headquarters to Texas.

The Spring-based company announced this week that the redomiciliation from New Jersey to Texas is expected to be effective July 1. Exxon's board of directors unanimously recommended redomiciling in the Lone Star State in March, and shareholders approved the move to Texas at the company’s annual meeting in May.

As part of the move, ExxonMobil Holdings Corp. will replace Exxon Mobil Corp. of New Jersey and become the publicly traded parent company. Exxon reports that its shares will continue to trade on the New York Stock Exchange under the ticker symbol “XOM,” and that shareholders do not need to take action.

At the time of the recommendation, Exxon said the move would not affect business operations, management, strategy, assets or employee locations.

Exxon Chairman and CEO Darren Woods added that the redomiciliation was in part due to Texas' business-friendly environment and policies.

"Over the past several years, Texas has made a noticeable effort to embrace the business community. In doing so, it has created a policy and regulatory environment that can allow the company to maximize shareholder value,” Woods said in a news release. "Aligning our legal home with our operating home, in a state that understands our business and has a stake in the company’s success, is important.”

The Associated Press reports that about 30 percent of Exxon's employees work in Texas. Exxon's legal headquarters has been based in New Jersey since 1882, when it was Standard Oil Company.

Exxon moved its operational headquarters from Irving, Texas, to the Houston area in 2023.

Exxon was the highest-ranking Houston-area company on this year's Fortune 500 list, coming in at No. 9. Houston tied with Chicago for the second-most Fortune 500 headquarters on this year's list, with Texas leading the nation for the most Fortune 500 headquarters (57).

“Texas is the undisputed headquarters of headquarters,” Gov. Greg Abbott said in a news release. “The world’s leading businesses invest with confidence in Texas because of our welcoming business climate, predictable regulatory environment, and skilled and growing workforce. People and businesses are choosing Texas because Texas works.”

Houston startups named to World Economic Forum cohort for carbon removal, clean technologies

top honor

Two Houston-based startups have been selected to join the World Economic Forum's Technology Pioneers community.

The two-year program aims to help mission-driven, early-stage start-ups scale their innovations through multi-stakeholder initiatives, co-creating partnerships and other gatherings for community members. One-hundred startups are selected each year from around the globe, this year hailing from 23 countries and working in AI, energy, space, biotech markets and more.

Cleantech startup Vaulted Deep was one of 11 energy and climate companies to be named to the cohort. Julia Reichelstein and Omar Abou-Sayed founded the company in 2023. Its technology injects excess organic waste underground to remove carbon dioxide from the atmosphere.

Last year, Vaulted Deep inked a 12-year deal with Microsoft to remove up to 4.9 million metric tons of carbon dioxide from the environment.

The startup has earned several accolades in recent years, including a No. 3 spot on Fast Company’s list of the World’s Most Innovative Companies of 2026. It was also recently named to market intelligence and advisory firm Cleantech Group's annual Global Cleantech 100 list for a second year in a row.

"Waste management is one of the world's great invisible infrastructure systems ... The need for new infrastructure is growing as disposal challenges become more complex and regulations evolve. Vaulted is building the first new disposal pathway for organic waste in decades by putting it deep underground, permanently," the company shared in a LinkedIn post. "This year, we're joining the World Economic Forum's 2026 Tech Pioneers alongside innovators working on the many interconnected challenges shaping our future."

Houston-based Venus Aerospace was also selected to join the cohort, along with six other spacetech companies. The company was founded in 2020 by Sassie and Andrew Duggleby.

The startup specializes in next-generation rocket engine propulsion as a cleaner alternative to traditional combustion engines. The company's rotating detonation rocket engine (RDRE) burns fuel more efficiently and completed a successful high-thrust test flight last year. Venus says it’s the only company in the world that makes a flight-proven, high-thrust RDRE with a “clear path to scaled production.”

"Frontier technologies matter most when they expand what people, industries, and nations can do," Sassie Duggleby, co-founder and CEO of Venus, said in a news release. "For Venus, RDRE does not just represent a more efficient engine. It is a foundation for faster movement, more capable space systems, and new forms of connectivity across the planet. Being named a Technology Pioneer validates the potential of this technology to help shape a future where distance is less limiting."
