Nuclear is simply incompatible with renewables, if the price tag is of any concern to you. Nuclear reactors take long and cost a lot to build, still aren’t cheap to operate if you include the infrastructure cost of getting, handling and storing the fuel, can’t respond to changing demand quickly and are centralized.
Nuclear power plants need subsidies over their whole life, mainly to handle the risk inherent with nuclear fuel and the finincial risk of having to handle spent fuel for centuries to come. Nuclear power plants need to run at full power, which costs money every time renewables are pushing the energy price into the negatives. Nuclear power plants need a centralized power grid.
Renewables work in exactly the opposite way. They are cheap to build and maintain, they are variable and decentralized. So to use renewables effectively, you need to build a decentralized grid and ideally on-premise energy storage.
Renewable energy simply wins in terms of cost, risk-management and scalability. So the energy grid of the future will be purpose-built to accomodate renewable energy. Trying to force nuclear energy generation into that mix only makes sense, if you have a clear, non-monetary reason to do so, like enriching uranium for bombs. For strictly commercial use, nuclear power is dead.
Because hydrogen-ready power plants are not the same as natural gas power plants, as hydrogen gas is not a drop-in replacement for natural gas. And right now, when natural gas is still relatively cheap and renewable energy is not yet absolutely dominating the energy mix, politicians are fearing the cost of building the infrastructure for generating, transporting, storing and burning hydrogen gas.
In the future, hydrogen gas plants promise to be the best fit to pair renewable energy with, but right now the cost of it and the availability of fossil fuels do not force the hand of the people responsible for planning the future of the energy grid.
