Externet Posted January 4, 2020 Posted January 4, 2020 Hi. How many kilowattshour are needed to create 1 Kg of hydrogen ? ----> https://news.stanford.edu/2019/03/18/new-way-generate-hydrogen-fuel-seawater/ Do not see much news of the electric vehicle Quantino these days . Another flop ?
swansont Posted January 4, 2020 Posted January 4, 2020 IIRC electrolysis is ~1.25 eV, so it would be 7.5 x 10^26 eV for a kg. That’s 120 MJ, or 33.3 kWh 2
