DOE grants Houston-area energy tech co. over $5M for rare earth elements study

The Woodlands-based Tetra Technologies, an energy technology and services company, has picked up nearly $5.4 million in U.S. Department of Energy funding to study the recovery of rare earth elements and other critical minerals from coal byproducts in Pennsylvania.

The funding also will enable Tetra to explore converting coal byproducts, known as underclay, into clays that could be sold. In addition to the DOE funding, the company also secured about $1.3 million for a total of $6.7 million.

Publicly traded Tetra got the funding as part of a more than $17 million package aimed at designing and building facilities to produce rare earth elements, along with other critical minerals and materials, from coal resources. The Department of Energy (DOE) says these minerals and materials will go toward generating clean energy.

Rare earth elements can be derived from the country’s more than 250 billion tons of coal reserves, over 4 billion tons of waste coal, and about 2 billion tons of coal ash, according to DOE.

Clean energy fixtures like solar plants, wind farms, and electric vehicles generally require more minerals to build than their fossil-fuel-based counterparts, according to the International Energy Agency. For example, a typical electric car requires six times the mineral resources of a conventional car and an onshore wind plant requires nine times more mineral resources than a gas-fired plant.

The American Geosciences Institute says rare earth elements, a set of 17 metallic elements, also are an essential component of many tech-dependent products. These include cell phones, flat-screen TVs, and radar and sonar systems.

China is the top country for production of rare earth elements, with the U.S. far behind at No. 2.

Software giant Microsoft is negotiating exclusively with Houston-based oil and gas titan Chevron and investment firm Engine No. 1 about the development of a $7 billion power plant in West Texas that would supply electricity for a Microsoft data center campus.

The proposed natural-gas-fired plant initially would generate 2,500 megawatts of electricity, Bloomberg reports. The plant would be built near Pecos, a Permian Basin city, in an area where Microsoft plans to build a 2,500-megawatt data center campus on a 7,000-acre site.

A deal with Microsoft would secure a long-term customer for the plant’s output and help finance its construction, Bloomberg says. The project, expected to be producing power by 2030, still requires tax and environmental approvals as well an agreement to terms among Chevron, Engine No. 1, and Microsoft.

In a statement issued after Bloomberg reported the news, Chevron acknowledged it was in exclusive talks with Engine No. 1 and Microsoft, but the oil and gas company offered no details.

Chevron says the proposed plant “reflects an emerging shift in how power for AI is being developed, bringing energy supply closer to demand through co-located, behind-the-meter generation to deliver reliability while helping avoid added strain on regional electricity systems. It pairs sustained, always-on demand from advanced computing with proven capability to design, build, and operate large-scale energy infrastructure.”

Development of gas-powered electrical plants for AI data centers represents a new—and potentially lucrative— business line for Chevron. In 2025, Chevron, Engine No. 1 and GE Vernova announced a partnership to produce natural gas for AI data centers in the U.S.

Chevron’s collaboration with Engine No. 1 has already secured an order for seven large natural gas turbines from GE Vernova, according to Bloomberg.

“Energy is the key to America’s AI dominance,” Chris James, founder and chief investment officer of Engine No. 1, said last year. “By using abundant domestic natural gas to generate electricity directly connected to data centers, we can secure AI leadership, drive productivity gains across our economy, and restore America’s standing as an industrial superpower.”
