The focus on electricity is probably secondary: Any energy source can be converted into electric energy.
The focus on fuel cells is probably secondary, too: Hydrogen can simply drive combustion engines as well; if the hydrogen and oxygen sources are sustainable, then the combustion engine will be as sustainable as the fuel cell (minus potential efficiency ...

A residential hydrogen-fuel-cell is a solid-oxide-fuel-cell which makes a lot of heat when it produces electricity.
The waste heat has obvious uses for the house or building but also the most likely source of hydrogen is to steam propane or natural-gas. So there is plenty of heat for that process once the fuel-cell is running. The only thing needed is the ...

No. There is no readily available supply of net-positive-energy hydrogen on Earth, where most human power usage takes place. Hydrogen fuel cells may be a useful component of a total energy system but they are not a source of generation capacity. Hydrogen is more like a battery than a supply of energy. Hydrogen can be liberated from water by using energy. ...

As far as Europe is concerned, more than half the new generating capacity installed in 2018 was wind turbine, the the amount installed in the first 6 months of 2019 is increased relative to 2018. In the US, AWEA is reporting that the 3rd quarter rate of installation of new wind turbines was, at just under 2GW, "highest third quarter on record". Doesn't look ...
