But where do we store the energy is the question. Without storage renewables aren't that useful.
Pumped hydro, hydrogen, batteries. The solutions are readily deployable and economcally viable.
Are they, though? Can you list some bigger storage facilities based on either H or batteries? Like ones that would power a city for few days, for example.
I can't but it's also not necessary. There are no conditions were no energy from renewables is produced. You have to cover peaks and shift electricity around a bit. The missing parts are interconnection and, dependend on price, overbuilding.
I can guarantee you that there are conditions when sun and wind aren't producing a thing or very low output, like during night you are at mercy of wind (hydro is another story, is more stable but even there we experience droughts). So, what do you do when all three (night, no wind and drought) hit you like for a week?
Edit: typo
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....
Now you are getting away from arguments...
You think? I'm saying that we can have a strategy, but that doesn't guarantee the outcome. Again, show me a city scale energy storage today. So, until we have one, it's vaporware. Basically this strategy is based on what exactly? Hope?
The strategy is being implemented, infrastructure being build. Electrolysers and hydrogen ready NGs are planed and build. New NG infrastructure is hydrogen ready. What else are you expecting? Should things magically materialise?
Let's continue the conversation after a couple of years?
Ok, have it your way. Hydrogen Supply Outlook 2024: A Reality Check
Awesome, I win! But seriously, I do hope we pull something off ASAP, being hydrogen or some sort of battery or whatever.
Have you read the article? Hydrogen is developed... fast...
