Green Hydrogen Economy: Holy Roman Empire?

We model the green hydrogen value chain: harnessing renewable energy, electrolysing water, storing the hydrogen, then generating usable power in a fuel cell. Today’s costs are very high, at 64c/kWh. Even by 2050, our best case scenario is 14c/kWh, which elevates household electricity bills by $440-990/year compared with decarbonizing natural gas.
