Plankton Power: Organic Matter Harnessed In Underwater Fuel Cells

Summary:
ONR’s oceanic fuel cell is called OSCAR (Ocean Sediment Carbon Aerobic Reactor). Organic matter in the sediment serves as the fuel which is connected to dissolved oxygen in the sea water by electrodes, allowing electrons to flow in the same manner as a conventional fuel cell. Microorganisms that naturally inhabit the sediment and sea water speed up the electron flow.

For hundreds of millions of years, plankton — those tiny drifting sea creatures found throughout the ocean – have been raining unceasingly on the sea floor as individuals die. There they’ve been deposited as organic (reduced carbon) matter in the sediment.
