In the EU, hydrogen. Either by fuel cell or burnt in hydogen ready NG plants. Wouldn’t be my first choice but thats whats gonna happen.
Could be, however hydrogen is really tough to handle plus green generation is around 50% efficiency (something like that). Also imagine having huge hydrogen volume and there is a spark…
Well… It’s the current strategy.
Also, the same could be said about NG [efficiency about 30%-55% and also a little bit flameable].
Strategy doesn’t mean it will be actually implemented or it’s the best. For example, Ursula instructed the transportation guy to try to implement Hyperloop. Shall I say more? :) There is also strategy to ditch fossil fuel cars soon…
