Collaboration to evaluate feasibility of powering offshore fish farms with marine energy

Determining the potential of powering offshore fish farms with ocean thermal energy conversion.

Researchers with Argonne, Florida Atlantic University, PCCI, Inc., and Gulfstream Agriculture, LLC, are using feasibility analysis and system modeling to determine the potential of powering offshore fish farms with ocean thermal energy conversion. Anticipated global growth of offshore aquaculture — which has typically relied on diesel-electric generators to meet its energy needs for monitoring and surveying instruments, automated harvesting/processing, and equipment such as pumps and lights — presents an opportunity to reduce greenhouse gas emissions by switching to renewable sources. Marine renewable energy (energy from waves, tides, currents, and ocean gradients) can support the expansion and decarbonization of seafood production and ecosystem restoration by providing power to ocean farms, including shellfish, seaweed and finfish. Argonne Energy Systems Scientist Tianqi Hong is principal investigator for the project, which is funded with $250,000 from the Department of Energy Office of Energy Efficiency and Renewable Energy-Water Power Technologies Office.
