The Advanced Research Projects Agency – Energy (ARPA-E) is offering a Funding Opportunity Announcement (FOA) titled "Grid-Free Renewable Energy Enabling New Ways to Economical Liquids and Long-Term Storage" (GREENWELLS), aimed at developing technologies that convert renewable energy and carbon dioxide into sustainable carbon-containing liquids. The program seeks to support experimental systems that can dynamically operate to maximize energy efficiency and minimize capital expenditures, particularly in sectors that are challenging to decarbonize, such as aviation and heavy-duty transportation. With approximately $38 million in funding available, ARPA-E expects to award around 15 grants, with individual awards ranging from $1 million to $5 million. Interested applicants must submit their proposals through the ARPA-E eXCHANGE platform by 9:30 a.m. Eastern Time on April 18, 2024, and can find additional information and guidance on the application process at https://arpa-e-foa.energy.gov.
