It'd probably be helpful to elaborate, rather than just insist that the above commenter is wrong and loosely suggest at other solutions.
Things like hydrogen storage, synthetic methane, and thermal storage remain in the prototyping phase. I think it's not correct to say that they can, seeing as there isn't even a commercial market for these technologies let alone one that we know will scale. By comparison countries have already powered >80% of their electricity with nuclear.
It's clear than nuclear power can completely replace fossil fuels. Renewables might be able to replace it, but that's a gamble based on assuming a new storage solution will work excellent. Not just better, but truly blows-everything-else-out-of-the-water phenomenal. When the stakes at play are stopping climate change, this is a very risky assumption to make.
Really? What company can I call up and buy 50 GWh of storage from? That's only 6 minutes worth of storage for the USA.
I'd say if we could provision 1 hour's worth of storage over the span of a decade, that'd amount to a demonstration of economic feasibility. But few of these upcoming technologies are making it out of the prototyping stage, let alone commerical success on this scale.
There isn't a company you can call up because projects of this magnitude aren't quoted over the phone to internet forums users.
50 GWh is stored in ~30,000 barrels of synthetic fuel. GWh is an incomplete way to specify storage, there are different technologies for the different ways storage may be needed, depending on what resources are on the grid: short term to handle the peaks of everyone microwaving their breakfast and coffee at 7am or long term storage to handle a once every few decades event like a Texas snow storm.
No one is presently making these because the policy of the grid was developed around power plants that dig stuff out of the ground and burn it - the markets are based on bidding with the assumption every power plant will have a marginal cost of generation relative to the cost of its fuel. This policy doesn't reflect the nature of renewables which besides their capital cost have very low to 0 marginal cost of production. This has disrupted the energy markets in many ways and policy is still being developed to incentivize storage capacity.
The point is that saying "No one is presently making these" on one hand, and claiming that they're within existing industrial capacity is contradictory. Energy markets like Hawaii and California are already hitting situations where energy cost is near zero due to overproduction from intermittent sources. But the promise that entrepreneurs will store this energy and put it back on the grid later has yet to pan out - contrary to the insistence of storage evangelists, hydrogen storage, synthetic methane, thermal batteries, and whatnot are a lot harder to build than one might think.
It's not contradictory. The storage is not being done now not because it's impossible, but because the market conditions that would cause it (specifically, high carbon taxes) aren't there yet. Something like pumped thermal storage requires no new technology. It's just putting together things we can already build.
I'm glad you can google "energy storage" and click on one of the first links but literally none of these are currently capable of replacing baseload nuclear and fossil fuel energy generation.
You can listen to the people who work in this industry and have studied it deeply or you can keep googling furiously for webpages that support your magical thinking.
I didn't "furiously google" anything I "calmly referenced" some of the MANY notes I have from following articles, podcasts, and journals in this field, which I have spent most of my career in.
In fact, I didn't see ANY links from you supporting your nonsense about renewables not working, despite them working in many places across the globe.
>literally none of these are currently capable of replacing baseload nuclear and fossil fuel energy generation.
Literally STORAGE will never replace GENERATION, they are two different concepts which most people understand but you apparently don't. STORAGE can supplement INTERMITTENT GENERATION to create DISPATCHABLE GENERATION for far cheaper than nuclear plants.
