To extract 1kg of hydrogen with electrolysis you need ~50 kWh with inefficiencies (39.4 with no losses)[0], while one kilo of hydrogen only has 33.6 kWh[1]-roughly 1.17kWh to produce 1 kWh worth of hydrogen (no losses). For diesel, it seems to be quite similar-roughly 1.18 kWh per 1 kWh, however in reality at current efficiencies for hydrogen it is more like 1.5 kWh/1kWh. It seems companies need more incentive to switch to hydrolysis based solutions to cancel out the much higher costs of hydrogen storage [0] https://www.weforum.org/agenda/2023/09/seawater-electrolysis...
