lmao, you say shit study but you suggest using green h2 as backup which not only isn't economically feasible (for now at least) but current generators are either using a mix with gas or use pure h2 with huge nox releases due to high temp burning. Not just that, most lcoe costs magically assume that 4h storage is enough. Look at yesterday's Germany generation and tell me how 4h storage will be enough there. Or maybe I should link to amount of subsidies Germany is pouring each year in renewables like https://www.bloomberg.com/news/articles/2024-05-29/germany-s... or like https://www.reuters.com/business/energy/germany-looks-specia... It's funny that when I ask ren-bros how much subsidies edf in France is getting they are either silent or are linking to price shielding that's totally unrelated and is present in most eu countries after russia's invasion. Renewable bros as usual are dunking on nuclear and promoting their clean supply like a mecca without facing hard reality - most renewables now are subsidized by fossils and will be in any close future

That's poor logic, h2 as a last-2%er doesn't need to be feasible until we've gotten to the 98% mark. And honestly, h2 feasibility is a function of cheap energy anyway, which probably means midday solar while solar farms are chasing dusk prices.

not, h2 feasibility in the context of power generation depends on many more factors, including how frequent the plant is used when day hours will be mostly tapped by solar generation and how you'll do price compensation. And in the context of h2 for renewables as a peaker, it'll need to be much more than 2%. And again, the emission problem for h2 generation isn't solved yet beyond fuel cells
