Until renewable energy inputs approach the base load, there’s nothing to store.
After that, hydrogen is an awful storage medium because it’s so permiable. Even if you’re focused on long term energy storage needs, sodium and nickel batteries are proving far more efficient than hydrogen cells. We’ve known that since the 90s, but continue to invest wasted billion after wasted billion in a dead end technology.
You were also decrying them spending money on battery storage. Yes there will be batteries needed if you want to implement large scale renewables, which it seems is happening even without subsidies. We need batteries for battery electric trains and cars too. Hydrogen isn’t necessarily good enough for grid storage, though maybe it could be one day. It seems it might be an option for vehicles in the cases where batteries don’t work such as in cold weather or for vehicles that need to travel great distances. Batteries also aren’t an option for planes yet and hydrogen could help here too.
You also complain about them spending money on advanced nuclear reactors. You need nuclear until you have sufficient grid storage. That’s an unfortunate fact.
I am against them using money on carbon capture from fossil fuel plants. Direct air carbon capture could actually be useful technology though. If not today then someday in the future. We won’t know if we don’t put money towards it.
Batteries on trains are not really needed if the rail is electrified. In Europe we have them everywhere. And better public transport reduces the need for cars. And ebikes can be the solution for many uses. It only takes thinking outside the car box.
Electrified rail is expensive and has safety issues. It’s the best option for long distances for sure, but here in the UK we are still trying to electrify the main rail lines, the branch lines and city lines aren’t even in the cards. Being able to recharge trains at stations with rapid charging is the best option for branch and commuter rail services not already on electrified rail (most of them). If we can do that using something other than lithium batteries that would be great. Sodium seems promising. Also I am in Europe you muppet. It also doesn’t solve grid scale storage, which is something we need. I am hoping iron oxide batteries work out for the grid scale storage tbh.

I don’t even drive and even I know cars, lorries, tractors, and so on are all necessary in some parts of society. You can’t use public transport if you are miles away from the next house or the nearest town. Rural areas need transport too.

Relative to the volume spent on generation, yes.

Given the abject failure of Westinghouse to produce a reliable mass production model, it’s an enormous waste of investment.
If nothing else, we’d be better of someone buying existing designs from Areva. But we don’t do that, because we insist on “Buy American” legislation that doesn’t get us any actual product.

Not relative to simply reducing the volume of carbon produced, by shifting the composition of the grid.

You understand that there are already too many greenhouse gases, right? By the time we do all of this there will be even more. It’s not like the grid is the only (or even the majority) of greenhouse gases. How do you account for both all the past emmisions and all the future emissions plus emissions from other sources?

The main alternatives being French and Chinese reactor designs. I can understand why the USA doesn’t want to use Chinese reactors, we in the UK made a similar decision and went with French designs instead if I am remembering correctly. I wouldn’t be against the USA using French designs. The thing is though I can’t see how more research could possibly be a bad thing, we have much work to do in both fission and fusion technologies. Putting all our bets in China or France might not be the best idea.
