Extracting H2 and O2 from plain water has an efficiency of over 80% from energy delivered by solar energy which is for free even if solar panel efficiency is now around 22%

Salt water with nickel sponge sulfate cover are closer to 90% (I know a start up claiming over 88% efficiency)

sciencedirect.com

Efficiency of producing Liquid organic hydrogen carriers (LOHC) depends on the formulation
Present fuel cells for electricity are at an efficiency below 60%

Efficiency of H2 electrical power station in a combined cycle setup are over 80% in Germany

Overall efficiency is slightly over 65% and water in the oceans is for free.

Best NG combined cycle power station is at 60% but extracting NG cost also $$$ not for free

Best internal combustion engine below 60% but above 50% on selective engines

Weak link in H2 use are: is its flammability as gas and the low efficiency of the known fuel cells.

So it is for all of to judge what is better

Since 2015 and also in my 2016 presentation at Eilat Eilot I claimed that hydrocarbon and NG days are numbered

At the time many were asking what I am smoking - well I do not smoke - 3 to 4 years later I am proven right
