There are rarely shortages of electricity in the US. There were some in California during Covid, and the state had to do rolling blackouts. But no, there are rarely shortages of electricity. Yes, someone could use more of it than we could

And are we currently using any of these caverns for electrolysis and grid storage? All you said is that we have a big cavern that we could fill with hydrogen. I'm asking if anybody is actually building hydrogen grid storage at any sign

"Demand shaping" is a nice euphemism for energy shortages. And if we demand shaping we're just externalizing the cost to consumers that need to buy their own energy storage or change their energy usage patterns to accommodate

It's not "nothing can be invented". It's "come back to me after it's invented, not before". And uranium seawater extraction already exists: https://www.forbes.com/sites/jamesconca&#x

Right, and what company can I call right now to install 50GWh of hydrogen storage? It's existing technology, but it's a novel application of that technology. We haven't used hydrogen electrolysis as a form of grid storage bef

None of those other battery chemistries are seeing the massive growth that lithium ion batteries have experienced. The nuclear "stans" are just pointing out that these are potential solutions, not actual solutions. If iron oxide b

Hydrogen storage remains in the prototyping phase. We have no significant amount of hydrogen grid storage. Like thermal batteries or synthetic methane, hydrogen represents a potential storage solution but not one that we know will scale and

Nowhere in the interview you linked to did the Minnesota governor say that the journalist was arrested for filming, either. The CNN journalist was far from the only person arrested. If the cops were arresting people for filming, not for vio

This thread seems to be triggering rate limiting: What "hard evidence" contradicts it? Can you provide evidence that no such dispersal order was given? Or that they were arrested prior to such order, or curfew? In fact the source

Nuclear fuel can also be recycled. Again, the energy density of fission is such that producing the same amoy of energy results in orders of magnitude less waste. Decommissioning nuclear plants doesn't change this figure.

Germany, Japan, Sweden, Korea, Ukraine, Belgium, Spain, Finland, and Argentina form a non-exhaustive list of countries that have built reactors without weapons. The reactor designs are often licensed, but reactors are constructed on site. I

And we also have examples of France's Messmer plan. And the US nuclear boom during the 1970s. But I'm sure you're prepared to hand-wave away these examples, too. Countries have built nuclear power beyond 80% of total energy

Right. If we build nuclear plants to fulfill peak energy demand (which coincides with a lack of energy production from solar) then there's not reason not to just run the nuclear plants 24/7 and skip building solar altogether. This

What do you mean by 17GW of storage in the pipeline? I'm not seeing this in your sources. Watts isn't a measurement of storage, storage is measured in watt-hours. To put the mismatch between available storage and required storage

Sure, but there's also the mining and purification of silicon to produce solar power. Same with the mining and purification of steel and aluminum to produce windmills. The energy density of uranium is much, much greater than all of the

Cost overruns have been the norm, but nuclear power generation at scale during the 1970s was still at most half as expensive as the Votgle and Flamanville projects that you like to cherry-pick. The atrophy of the nuclear supply chain is pre

The entirety of the United States' nuclear waste from power generation occupies a volume the footprint of a football field, and less than 10 yards high [1]. The main draw of nuclear power is it's waste: there's so little

So it nuclear costs as much as offshore wind, but it's not intermittent? That's very strong advantage: non-intermittent generation avoids the need to overproduce and store energy.

A nuclear plant costs the same to run at full capacity all year round as it does to run it at partial capacity. Just run the plant at full capacity all year round, and save money by building less solar.

But the point is, we have built nuclear at scale. And built it at scale. France has over 70% of its electricity coming from nuclear, Belgium over 50%. The US is at ~10%. We've encountered the emergent issues, and fixed them. Cost est

Resorting to ad hominems only demonstrates that you're not interested in engaging productively. So this claim about having infrastructure to manipulate hydrogen is referring to the chemical industry, where hydrogen frequently used as a
