You can run power to gas and then burn the hydrogen and still come out ahead of nuclear plants today. They are completely irrelevant.

No point comparing like for like. The end game is a stabile balanced grid. If that is fulfilled by 100% intermittent or 100% deterministically dispatchable does not affect anything in regards to the end user. All they want is reliably the c

So I guess the next goal here is a startup to implement this as a smart contract to go full circle. The market will do it because any transaction fee is a hindrance to it's liquidity and is a possibility to undercut someone else.

Unsubsidized on-shore wind and solar is the by far cheapest sources of energy today. They are down at the marginal cost of existing, paid of, traditional power plants. That is where the current explosion in renewable growth is coming from.

We've had fast reactors since the 70s. It is simply that they are even less economical than regular nuclear power plants, and those are already completely uncompetitive compared to renewables. > Breeder reactors are costly to build

They do. This graph shows the nuclear "baseload" being crowded out of the market by cheaper renewables. (Or in this case mostly coal, but they are about equal on the electricity market in terms in inflexibility and cost structure.

The thing is, they don't complement each other at all. They both compete for the same share of the market: the cheapest most inflexible power generation. Renewables win there and force nuclear plants to be more flexible. Due to the ext

It is more expensive. The reason why Lithuania and Poland built LNG terminals is not because it is economical or fun compared to pipelines. It is a pure sunk cost. The reason is to secure their supply incase Russia wants to exert influence

Is not that the thing? Working in software I am already competing with the world. My job could get out-sourced tomorrow, but apparently that does not happen. See the difference? Value vs. cost. Very different.
