$500 KWh is still much more expensive nuclear. Furthermore competition with electric vehicles isn't going to decrease battery cost, it's going to increase it. More demand for a constrained supply leads to higher prices. Wind is al

Nickel-Iron batteries have 10-20 times less energy density and are more difficult to manufacture. You might get a battery that lasts 30-50 years instead of 5-10 years but at a cost increase that's greater than the gain in number of cyc

The batteries need to be replaced every 5 to 10 years depending on how many cycles they can endure. By comparison, the AP-1000 is rated to last 60 years. Furthermore you're being very pessimistic with the $20 billion dollar cost estima

Peak demand for electricity occurs in the evening. If you're going to fulfill this demand with nuclear power, the just run the nuclear power plants at full capacity all day and don't bother with any storage or solar panels.

Nuclear waste sits in sealed concrete containers, and is stored by burying it in bedrock with no aquifer. There's so little of it that we can store it securely. Solar panels on the other hand... https://www.sciencedirect.com

You use the word "smart grid" as though it just automatically makes electricity usage go down. A smart grid works by redistributing load to when there is power. A smart grid almost always needs storage, unless it's doing simp

Electrifying heating doesn't improve this situation, it worsens it drastically. People come back home after work and turn on the heat or AC right as the sun goes down. A big part of why renewable generation is so high in Germany is bec

The enormous capital costs demonstrates how expensive it makes solar and wind in simple terms. Even if we measure in terms of cost per watt hour stored and drawn over the lifetime of the batter it's still hugely expensive. Most batteri

> A battery for 100/kwh can be used several 100 to 1000s of cycles. You're making the same error as reitzensteinm. The fact that you can charge and discharge a 1 KWh battery a thousand times doesn't make it a 1 MWh battery

by Manfredo_1 6y ago
No, that's not this works. Batteries currently cost ~$150 to $250 per KWh. As in, if you want to store one kilowatt hour, you need to spend $150 to $250 dollars on batteries. If you want to store one megawatt hour, then that's $15

Sure, a terrorist's goal is to create terror. But a higher body count is by far the most reliable way to generate more terror. Sure, a few people killed in a particularly gruesome way might create more terror than a numerically larger

by Manfredo_1 6y ago
The surface storage isn't at temperature, though. Waste is cooled off in a pool of water until it's cooled, before it's placed in dry storage. Sure, rupturing that would release toxic materials out into the surrounding area.

By "cultural changes" you mean energy shortages. Realistically, this would most likely result in leaders getting elected out of office and resuming the use of fossil fuels. Regular blackouts are immensely unpopular.

The US has about 8 seconds worth of battery storage. By comparison, to use renewables for 80% of our electricity we would need 12 hours of energy storage. For 100%, 3 weeks of storage [1]. 1 hour of energy storage in the US is 500 GWh. This

France's peak energy consumption is more than 40% higher than it's trough energy demand [1]. Most years France generates ~10% of its energy from fossil fuels. Nuclear was indeed used to supply a substantial part of the peak energy

This is just factually wrong. France had generated the majority of it's electricity from nuclear since the 80s, and Belgium now generates the majority of it's power from nuclear. Nuclear had repeatedly been used to satisfy peak de
