I’m not 100% sure what you’re asking, but from Wikipedia:
...current best processes for water electrolysis have an effective electrical efficiency of 70-80%,[38][39][40] so that producing 1 kg of hydrogen (which has a specific energy of 143 MJ/kg or about 40 kWh/kg) requires 50–55 kWh of electricity. At an electricity cost of $0.06/kWh, as set out in the Department of Energy hydrogen production targets for 2015[41], the hydrogen cost is $3/kg. https://en.m.wikipedia.org/wiki/Hydrogen_economy
Some quick googling indicates a kilogram of hydrogen seller for around $14, give or take.
There is inefficiency in hydrogen storage, but it should keep longer than a lithium ion battery.
How much cost of running machines for hydrolysis is currently payed for the electricity?
