Storage is a solvable problem. Whereas we don’t have the resources to power the world with nuclear plants.

Storage is a solvable problem

I’m not convinced it is. Storage technologies exist for sure, but the general public seems to grossly underestimate the scale of storage required to match grid demand and renewables only production.

I think you underestimate how much storage power is currently being build and how many different technologies are available. In Germany alone there currently are 61 projects planed and in the approval phase boasting a combined 180 Gigawatts of potential power until 2030. Those of them that are meant to be build at old nuclear power plants (the grid connection is already available there) are expected to deliver 25% of the necessary storage capacity. In addition all electric vehicles that are assumed to be on the road until 2030 add another potential 100GW of power.

Of course these numbers are theoretical as not every EV will be connected to a bidirectional charger and surely some projects will fail or delay, however given the massive development in this sector and new, innovative tech (not just batteries but f.e. a concrete ball placed 800m below sea level, expected to store energy extremely well at 5.8ct / kilowatt) there’s very much reason for optimism here.

It’s also a funny sidenote that France, a country with a strong nuclear strategy, frequently buys power from Germany because it’s so much cheaper.

It’s not just power that’s needed (MW), also stored energy (MWh).

Germany consumes on average 1.4TWh of electricity a day (1). Imagine bridging even a short dunkelflaute of 2 days.

Worldwide lithium ion battery production is 4TWh a year (2).

It’s also a funny sidenote that France, a country with a strong nuclear strategy, frequently buys power from Germany because it’s so much cheaper.

Isn’t that normal? The problems with renewables isn’t that they generate cheap power, when they are generating. Today windmills even need to be equipped with remote shutdown, to prevent overproduction.

The problems arise when they aren’t generating.

Another important note about France: They are the second country alongside Germany heavily pushing for an upscaled green hydrogen market in the EU. Because -just like renewables- nuclear production doesn’t match the demand pattern at all. Thus it’s completely uneconomical without long-term storage.

The fact that we seem to constantly discuss nuclear vs. renewables is proof that it’s mostly lobbying bullshit. Because in reality they don’t compete. It’s either renewables+short-term storage+long-term-term storage or renewables+nuclear+long-term storage. Those are the only two viable models.

Ok but maybe a counterpoint is we are overestimating the ability of the atmosphere and ocean to absorb CO2 and maintain a habitable planet. I’d rather store isotopes in the earth (where they came from anyway) than carbon in the air.

Again: This is just the beginning! We’re like five years into at the beginning of an energy revolution and you are drumming against it because you’re “not convinced”, rooting for stuff we already discarded because it’s uncontrollable and will poison our planet for centuries. Get out of the way, boomer!

Germany has over 400 MW of solar-plus-storage projects under development, with notable installations like a 100 MW/200 MWh battery system in Bavaria. This is way more than even the green minister of economic affairs set as a goal for 2045. California leads globally with 6,600 MW of battery storage already operational and an additional 1,900 MW expected by year-end, totaling 8,500 MW. By 2045, California aims to expand its capacity to 52,000 MW. Australia is also scaling rapidly, with around 9 GW of utility-scale battery projects underway or completed. Soon EV batteries get to feed energy back into the grid, we’re becoming one huge decentralized batterie mosaic. It’s gonna be beautiful!

Exactly, after working on it for over 30.

It seems like theyre not even planning on going fossil free.

That quote, again, not mentioning stored energy. How do they not understand that storage needs to be specified in both power and energy?

Not in this economy. We need change in consumption too. Make loads opportunistic. Have extra energy - heat more water. Or heat homes. There was video on Technology Connected about it.

The second half if most important. It doesn’t produce enough electricity. Renewables are getting cheaper and cheaper and are taking up the mantle to take over majority of power production in some nations. But it is harder to monetize and can be democratized and made pretty easily. It’s like weed. It can be taken away from bigger producers and therefore there is significant push back/lobbying against it.
