NOT SURE OF THIS, NEED TO CHECK IF THIS IS A REPEAT
The method, proposed by a team at Northwestern University, suggests that after “burning” traditional carbon-based fuels, the fuel cell generates concentrated CO2 that can be stored on-board the ship. From there, the CO2 can either be sequestered or recycled into renewable hydrocarbon fuel. The solid oxide fuel cell is critical because it burns the fuel with pure oxygen, yielding a concentrated CO2 product that is storable,” said Travis Schmauss, a PhD candidate in Barnett’s research group. “If we just burned the fuel with air, it would be heavily diluted with nitrogen, yielding too much gas to store. When the concentrated CO2 is compressed, it can be stored in a volume not much larger than that needed for the fuel, which saves space.
