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.

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.”

Kanin Energy raises up to $100M for waste-heat-to-power projects

fresh funding

Kanin Energy, a member of the Greentown Labs climatech and energy incubator in Houston, recently raised as much as $100 million in capital to grow its energy-as-a-service platform.

S2G Investments led a round of up to $50 million, and the Canada Growth Fund chipped in an additional $50 million. The money will primarily support Kanin’s development and operation of waste-heat-to-power projects.

Kanin—founded in 2020 in Calgary, Alberta, Canada—builds and runs onsite power assets for large-scale energy users. The startup says its energy-as-a-service offering lowers power costs, boosts power reliability and decreases emissions.

The company operates a waste-heat-to-power project at Ohio’s University of Dayton. The project supplies zero-emission electricity.

Kanin has a pipeline of projects totaling about 50 megawatts of capacity. This includes a waste-heat-to-power plant at the Phillips 66 Mewbourn gas-processing plant near Greeley, Colorado.

“Kanin was built on the belief that industrial facilities already hold the solution to their own energy challenges, they just need the right partner to execute,” Janice Tran, CEO of Kanin, who is based in Houston, said in a release. “At a time when power costs continue to rise, [our] solutions are an important tool for our industrial customers to manage their costs, operations, and emissions.”

Marisa Sweeney, principal at S2G, says waste heat is a largely underused resource for lowering power costs, alleviating grid congestion and improving power reliability.

The waste-heat-to-power process captures thermal energy from industrial activities and converts it to electricity. This happens without using extra fuel or generating more emissions.

Kanin says up to 58 percent of energy consumed by industrial processes is lost as waste heat. This heat winds up in the atmosphere at thousands of facilities in North America, including oil-and-gas operations, cement plants, and steel mills, the startup says.

Kanin was founded in 2020 in Calgary, Alberta, Canada. It opened offices at Greentown Labs Houston in July 2022.
