The U.S. Department of Energy (DOE) is considering rescinding over $1.5 billion in funding for clean energy initiatives, including carbon capture and long-duration battery storage projects, sparking significant opposition from lawmakers, industry leaders, and environmental advocates.

This potential rollback targets projects funded under the 2022 Inflation Reduction Act and the 2021 Infrastructure Investment and Jobs Act, raising questions about the administration's commitment to clean energy and the legal obligations to uphold congressional appropriations.

The DOE's proposed cuts could affect several key initiatives:

• Carbon Capture Projects: Four pilot projects and three full-scale demonstrations across California, Texas, and North Dakota, totaling approximately $1.2 billion, are at risk.

• Long-Duration Battery Storage Projects: Six out of nine projects, including those by NextEra and Westinghouse, which collectively received $350 million, may face funding reductions.

These technologies are crucial for integrating renewable energy into the power grid and decarbonizing electricity.

Startups like ReJoule and Smartville are already experiencing operational challenges due to funding uncertainty.

A group of Democratic senators, including Martin Heinrich and Patty Murray, sent a letter to Energy Secretary Chris Wright on April 2, 2025, urging adherence to legal obligations to fund clean energy initiatives as mandated by existing laws. The senators emphasized that the Constitution mandates the executive branch to faithfully execute laws enacted by Congress, including the obligation to spend appropriated funds.

"Our Constitution gives Congress the power of the purse and exclusive power to appropriate funds," the senators stated in their letter, emphasizing the executive branch's duty to execute laws enacted by Congress.

The proposed funding cuts raise questions about the administration's adherence to constitutional mandates regarding the execution of congressionally appropriated funds. Reducing support for carbon capture and battery storage projects could hinder progress toward decarbonizing the power grid and meeting climate change mitigation goals. Startups and established companies involved in these projects may face operational challenges, potentially leading to job losses and reduced innovation in the clean energy sector.

The DOE's consideration of rescinding funding for critical clean energy projects has ignited a multifaceted debate encompassing legal obligations, environmental priorities, and economic impacts. As the administration reviews these initiatives, stakeholders across the political and industrial spectrum continue to advocate for the preservation of investments that are pivotal to the nation's clean energy future.
