Reply to comment by The_Countess in Egypt inked deals on renewable energy, green hydrogen worth $119 bln by Wagamaga

Green hydrogen only makes sense if you scale your generation for winter needs, and therefore have excess in summer that you can't use otherwise.

And it only makes sense for stuff that you can't power otherwise. (ie efuel kerosene for aviation)

Well with renewables, there's a lot of fluctuation all the time. If solar and wind are able to power the entire country on a calm and cloudy day, there's going to a lot of excess during windy sunny days. Green hydrogen generation would ideally utilize these peaks.
