Trump administration to claw back $3.7B in clean energy and manufacturing awards

by | May 30, 2025 | Technology

The Department of Energy announced today that it would be clawing back $3.7 billion worth of awards made under the Biden administration for clean energy and manufacturing. Large corporations and growing startups were caught up in the decision.

Energy secretary Chris Wright said the moves were “due diligence” on the part of the Trump administration. His statement did not cite specific reasons why the projects were canceled, but pointed to a memorandum he issued on May 15, which suggests that the department may attempt to use its audit powers to rescind the awards. 

In total, 24 projects are affected by the move, including ones being developed by oil and gas giant Exxon Mobil, food manufacturer Kraft Heinz, industrial heat startup Skyven, cement and alumina startup Brimstone, and cement startup Sublime Systems.

Here’s a sampling of some of the awards in jeopardy:

American Cast Iron Pipe Company (metal manufacturing): $75 million

Brimstone Energy (low-carbon materials): $189 million 

Calpine’s Baytown Energy Center (natural gas power plant): $270 million

Calpine’s Sutter Energy Center (natural gas power plant): $270 million 

Eastman Chemical Company’s Longview Plant (molecular plastic recycling): $375 million

Exxon Mobil’s Baytown Olefins Plant (chemical plant): $331.9 million

Skyven Technologies (heat pump steam generation): $15.3 million

Sublime Systems (low carbon cement): $86.9 million

Sublime told TechCrunch that it was caught off guard.

“Sublime was surprised and disappointed to receive the news about the termination of our Industrial Demonstrations Program award, given the clear progress we’ve made in scaling our American-invented technology, partnering with some of the Western World’s largest cement producers, and generating a bankable customer base,” spokesperson Rob Kreis said via email. The startup is evaluating its options to continue scaling up its operations.

Brimstone is hopeful that things can be resolved with the DOE.

“Given our project’s strong alignment with President Trump’s priority to increase U.S. production of critical minerals, we believe this was a misunderstanding. Brimstone’s Rock Refinery represents the only economically viable way to produce the critical mineral alumina in the U.S. from U.S.-mined rocks,” Brimstone spokesperson Liza Darwin told TechCrunch via email …
