- pfdietz 4y agoFortunately, that very rarely happens, so backing it up with gas turbine plants (burning hydrogen, ultimately) is cheaper than dealing with the 365/24/7 high cost of nuclear.
- Paradigma11 4y agoNice, i would have guessed that duplicating the production infrastructure and the added loss of hydrogen transformation would be more problematic. Do you have any actual numbers at hand? "...is cheaper..." is a bit vague.
- pfdietz 4y agoI'll point to the simulation site I always link to: https://model.energy/ https://model.energy/ This uses real weather data for various countries and optimize solar + wind + batteries + hydrogen to provide a constant output at minimum cost. The results are interesting. You can tweak the cost assumptions.
