I have read both government studies on energy storage solutions and studies done by financial advisors to people who invest in the energy sector. The issue is always the high cost, with only specific places and situations where it is economical viable. In particular, if you can discharge the storage 365 days a year from 100% to 0%, selling at fairly high peak price, and do so for a capacity of 1-6hrs (depending on location and peak price), then it can be made profitable to operate a storage solution (depend also a bit on subsidies). Every other solution has yet to be found economical viable, and all of those other solutions are significant more expensive than nuclear. There are some alternative use cases. If you can convert the energy directly to a substance that an industry consume, like hydrogen in steel production, then the economics start to shift a bit. Hydrogen is produce today through natural gas, and if we include the carbon tax and introduce some subsidies to those who want to use renewables, then green hydrogen can be made to price match grey hydrogen in steel manufacturing. It not perfect, and its not storage, but it does reduce the use of fossil fuels. Burning the hydrogen for power however is still several times more expensive than nuclear, and I don't think people are willing to pay that kind of money in order to avoid nuclear power. The current way most governments seem to operate is to build out renewable generating capacity while also build out equal or greater amount of fossil fuel generating capacity. Looking at the Ukraine war, looking at the climate, and just looking at air pollution or graphs over fossil fuel usage, I am not optimistic that the current strategy are working at all. If anything it look exactly what the fossil fuel lobbying are pushing which is a future where they still hold a significant position and where the high peak price results in about as much profits as in the past but for a significant less amount of actually product.
