The Advanced Research Projects Agency - Energy (ARPA-E) is issuing a Request for Information (RFI) focused on engineering solutions to harvest biomass carbon for durable removal and storage, aimed at informing potential future programs. This initiative seeks input on innovative technologies that enhance carbon capture through photosynthesis, addressing the need to remove approximately 500 million tons of carbon dioxide equivalents annually by 2050 to meet national net-zero targets. The RFI emphasizes the importance of improving biomass yield, processing methods for carbon storage durability, and sustainable nutrient management, while also considering economic sustainability and environmental impacts. Interested parties are encouraged to submit their responses in PDF format to ARPA-E-RFI@hq.doe.gov by 5:00 p.m. Eastern Time on September 27, 2024, with further details available at https://arpa-e-foa.energy.gov.
