Yes, that shit study which models supplying the entire grid with one energy source and lithium storage through all weather conditions.
I would suggest reading the study I linked so you can see the difference in methodology when credible researches in the field tackle similar questions.
The credible studies are focused on simulating the energy system and market with real world constraints. Which apparently works out way cheaper when not involving nuclear in the picture.
That entire report is an exercise in selectively choosing data to misrepresent renewables and present nuclear power in the best possible light and wishful thinking.
To the degree that the prominent "renewables vs. nuclear" graph they keep repeating on the webpage and figure 6 in the report is straight up misleading.
This is the source:
What is different about different net-zero carbon electricity systems?
Utilizing storage costs from 2018 and then of course making the comparison against the model not incorporating any hydrogen derived zero carbon fuel to solve seasonal problems.
Which is todays suggestion for solving the final 1-2% requiring seasonal storage in the late 2030s.
Something akin to todays peaker plants financed on capacity because they run too little to be economical on their own, but zero carbon.
Would they have chosen the ReBF model the difference between made up optimal nuclear power and 2018 renewables would be: $80-94/MWh and $82-102/MWh.
It is essentially: Nukebros writes reports for nukebros, they confirm their own bias. Simply an attempt to justify another massive round of government subsidies on nuclear power.
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
>you suggest using green h2 as backup which not only isn't economically feasible (for now at least)
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
