The canceled funding includes noteworthy grants such as the $331 million award to Exxon Mobil, which sought to transition from natural gas to hydrogen in its Texas chemical facility. Additionally, $540 million in grants aimed at Calpine, a leading electricity producer, for carbon capture projects in California and Texas have also been terminated.

Energy Secretary Chris Wright stated that the terminated projects failed to adequately serve the energy requirements of Americans and were deemed unlikely to yield a positive return on taxpayer investment. Wright criticized the prior administration for inadequate financial scrutiny during the grant review process, highlighting that many of the awards were approved hastily between the November elections and the new administration's inauguration in January.

This funding cut reflects a broader reevaluation of strategies intended to mitigate climate change, as the Biden administration continues to navigate complex energy and environmental landscapes amidst evolving economic conditions.
