> Green hydrogen is scalable at about $400/MWh presently and this is decreasing rapidly. This was a wakeup call that doing so is needed. Ammonia is not far behind. Realistic projections for the next 8 years are around $100/MWh. The present price is obviously too high. I fully support any investment into this kind of tech, including from the government(s), though in my experience, even when tech is available, it takes time to roll it out. Maybe by 2050 we will have the ability to provide stable, fully renewable energy at $50/MWh or below, without being limited in how much we can roll out due to some rare mineral or industrial capacity. But we KNOW we have the tech to produce nuclear at such levels (or below) already. In my opinion, we should do both, and if, 30-40 years from now, some nuclear plant companies go bankrupt, so be it.

Re.

Look at the quarterly tab. And these claims that the prices can go down are contingent on serial production. 30-40 years is the time window at which significant capacity starts being made, not finishing. What matters is Joules before 2050 not starting at 2060, and even the most optimistic projections have them costing on the order of $200-500/MWh with nuclear.

  > Re. French nuclear saving the day: When supply cannot meet demand, prices do not represent production costs. Building a nuclear plant takes about 5 years. In situations with sufficient sense of urgency, construction speeds can be ramped up surprisingly quickly. From 1940 to 1944 US federal spending went up about ninefold (while GDP almost doubled as a result) The liberty ships were the most obvious example. Initially it took 230 days to build them (in 1941), in 1943 it took 39 days. A more modern example is the number of cars built by Tesla each year. From 2013 to 2023, the number of cars built per year will have increased by a factor of about 100x. Similar economies of scale are available for energy plants, if we choose to. For solar panels and batteries, we're already seeing this. If the political will was there today to vastly expand the amount of nuclear power, we would be able to produce A LOT within 10-15 years. The same goes for renewables, of course, as long as raw materials and technologies are available.
