The Department of Energy, through the Pacific Northwest National Laboratory (PNNL), is seeking information from developers and manufacturers regarding small-scale current energy devices intended for coastal aquaculture operations. The objective of this Request for Information (RFI) is to explore the feasibility of integrating current energy technologies to power aquaculture systems, such as shellfish tumblers and environmental monitoring sensors, using energy harvested from marine resources. This initiative is significant as it aims to assess the potential for co-locating marine energy resources with aquaculture, ultimately supporting future demonstration projects. Interested parties should submit their responses via email to Laurie Martin and Jay Wertenberger by 5:00 pm PDT on June 6, 2025, with the RFI open for responses from April 14 to June 6, 2025. For further inquiries, Laurie Martin can be reached at laurie.martin@pnnl.gov or 509-372-4071, and Jay Wertenberger at jay.wertenberger@pnnl.gov or 509-375-2117.
