At the Fuel Cells and Hydrogen for Maritime and Harbour Applications Workshop in Venice, Italy on June 14, 2013, Joe’s presentation focused on the opportunity for fuel cells to replace marine diesel generators for port and ship power, based in part on his and Aaron Harris’ report on the same topic.
