SWITCH is working on a 150-passenger, 25-knot catamaran to build for SF Bay Ferry, using the same GHstorage and fuel cell equipment 2as the first vessel. SWITCHhasfocusedonhydrogen for its potential to serve as an option where other solutions arent viable due to space and weight constraints. They find hydrogen as a fuel source can sup-port greater range and power require-ments due to its high energy density.
