>vehement hatred most other green people display towards nuclear (whether it is fission or fusion) is mind-boggling.

The hatred is understandable when you read stuff like this: https://www.theguardian.com/business/2023/dec/05/sellafield-...

One example of many many many. It really seems like replacing one problem with another.

That being said, my main problems with nuclear are 1) we solve the current acute problem much faster with solar+storage than with nuclear and 2) nuclear power drains much of same money that could be spent on solar+storage and 3) nuclear guarantees large expenses for future generations for the foreseeable future.

>We will not have the grid storage to do baseload via renewable+batteries.

Sure we will if we build it - there are no technical hurdles whatsoever to build all the storage we need, both batteries and gas are viable, and we also have pumped storage and other mechanisms. Moreover, since we have at least 10x the workforce with the required skillset to build storage than we have workers who can make nuclear plants, we can mobilize many more at once.

Seriously - if you want to reduce emissions right now, you need to subsidize storage. Green hydrogen, pumped storage, batteries, everything.

If we do this, not only will it start making a difference immediately, but 5 years from now we will have reduced emissions by the same amount as a bunch of nuclear power plants. Effects will be noticeable from year 1.

Meanwhile not a single nuclear power plant will be built in 5 years.

If the whole western world, China, Japan and Australia all want to switch to grid storage, we cant in a hundred years scale up production enough, especially because ’everything’ else in the world also needs batteries.

Building enough grid storage is a pie in the sky. Don’t fall for it- enough people do and we are all screwed.

I disagree. Making hydrogen and batteries is already so cheap that companies that need lots of energy are doing it for entirely financial and self-serving reasons. You can make hydrogen gas from water using things you have in a typical kitchen drawer.

It is by now technically cheaper for a steel mill to make it's own energy than to buy energy, even if they buy it from a nuclear plant that has already been built, and they can do it in 1-2 years. Once they have done it, they no longer use centrally produced energy, leaving more for the rest of us. Multiply this with thousands of large energy consuming companies everywhere and you have made real progress very fast.

Battery production capacity has grown exponentially and will continue to get cheaper thanks to the electric car transition. Cars get recycled and the batteries can be repurposed to storage, and in a few years when electric cars are the standard, the sales will plummet from the peak leaving enormous capacity available for grid storage. The latest battery chemistries in use in cars today use the most abundant elements on earth.

So, there are no logistical limits, no technological limits, no limited resources to prevent this from happening today, the limits are instead things like battery storage being taxed both when it stores energy and when it delivers energy, private producers being taxed on their own production and so on.

Such regulations are put in place to prevent the loss of control over a major part of the economy, and is IMO the main obstacle to solving the problem.

Talking about making nuclear plants is a nice way for politicians to keep control of the electricity money fountain, but nuclear power is IMO a very poor solution to the problem of fossil fuels since it will always be very expensive, slow to deploy, and a very bad problem all by itself.

where does all the copper and lithium come from to enable this mass electrification and storage of energy?

Let's hope we don't need too much cobalt too?

>where does all the copper and lithium come from to enable this mass electrification and storage of energy? Let's hope we don't need too much cobalt too?

We will save copper since electricity can be produced close to where it's being consumed, eliminating millions of miles of powerlines from central powerplants to everywhere else.

We need no lithium or copper at all in order to create hydrogen, ammonia or methane, and no lithium for iron-air batteries which are more suited for grid storage than lithium-ion.

We probably won't need any cobalt at all for grid storage, it is even being eliminated in electric cars already.
