The Advanced Research Projects Agency – Energy (ARPA-E) is offering a funding opportunity titled "Technologies to Emend and Obviate Synthetic Nitrogen’s Toll on Emissions" (TEOSYNTE), aimed at reducing nitrous oxide (N2O) emissions from U.S. ethanol production crops, specifically corn and sorghum, by 50%. Proposals are sought that utilize innovative plant and microbial bio-design strategies to decrease reliance on synthetic nitrogen fertilizers while maintaining crop yields, with a focus on achieving significant economic improvements and sustainability. This initiative aligns with national goals to enhance agricultural practices and reduce greenhouse gas emissions, with a total funding pool of approximately $36 million available for selected projects. Interested applicants must submit their proposals through the ARPA-E eXCHANGE by 9:30 a.m. Eastern Time on August 13, 2024, and can direct inquiries to arpa-e-co@hq.doe.gov for further information.
