The Advanced Research Projects Agency – Energy (ARPA-E) is offering a funding opportunity titled "Harnessing Autonomy for Energy Joint Ventures Offshore (HAEJO SBIR/STTR)" aimed at supporting the development of technologies for offshore seaweed cultivation, which has the potential to serve as a renewable biomass source. The program seeks to significantly reduce the costs associated with seaweed production while fostering a robust market for biomass and energy-centric applications, focusing on the development of sensors for real-time monitoring, engineering offshore infrastructure, and discovering new biostimulant applications from seaweed. With an estimated total program funding of $25 million, the agency anticipates awarding between 15 grants, with individual awards ranging from $314,363 to $4,505,859. Interested applicants must submit concept papers by February 13, 2025, and can find additional information and application materials through the ARPA-E eXCHANGE platform.
