“Green hydrogen”, is also incredibly inefficient in its own right. Approximately a 70 percent loss of energy compared to 15-20 percent for battery storage. It would literally be just as efficient to burn natural gas in a power station (with a 50+ percent efficiency, modern power turbines are very efficient) and use that power to charge a battery. The entire “hydrogen economy” has been a pipe dream by either complete morons or fraudsters (probably both). (Hydrogen aeroplanes might actually work, but that is by combustion and jet engines are already very efficient).
