OVERVIEWPropulsion of commercial vessels using solar energy based on Li-ion battery storage is limited to port stay use due to higher per kwhr cost and high power demand. Authors are proposing an alternative way of using hydrogen fuel generated by electrolysis of sea water powered from solar PV technology. Solar powered boat MS-Turanor design is taken for comparison purpose. Hydrogen can be freely generated & stored easily in compressed form in bigger tanks enough for a week long main propulsion of cargo ships. Cost per ton per mile is lesser than Li-ion use.
