    The problem is that there are currently no good (cheap, scalable) technologies to store these large amounts of electrical energy.

      There are several lines of storage research that only need to be ramped up to mass production at this point. Since stationary storage doesn’t have the weight restrictions that electric car batteries do, there are many different viable options. Flow batteries, sodium batteries, pumping water uphill, big tower of concrete blocks on pullies, hydrogen electrolysis, big ceramic block that gets hot. Some will work wherever, others are only viable in certain situations, but there are many options and we only need one of them to work at scale.

      When nuclear tries to make improvements, it tends to do one thing per decade. If it fails, wait another decade to try the next thing. Last decade, it was the AP1000 reactor. It was hoped it would make a single, repeatable design that would avoid the boutique engineering that caused budget and schedule overruns in the past. Didn’t work out that way. This decade, it’s Small Modular Reactors. The recent collapse of the Utah project doesn’t give much hope for it.

      Even if it does, it won’t be proven out before 2030. We’ll want to be on 90% clean electrical technology by then if we have even a hope of keeping climate change at bay. There is no longer a path with nuclear that could do so. Given project construction times, the clock ran out already.

        While I don’t disagree that it’s going to be too late, I do think SMRs are likely to go the distance, at least abroad.

        The reality is that we aren’t going to hit 90% carbon free by 2030 without a huge social and political shift. There’s just no way that is happening in 6 years. I really hate being a downer about it but I think we need to face the facts on it.

      Pumped hydro works well for storage, although it basically has the same problem as hydro power - it’s only available in places with water and elevation changes.

          Here’s the summary for the wikipedia article you mentioned in your comment:

          Kruonis Pumped Storage Plant (the KPSP) is located near Kruonis, Lithuania, 34 km (21 mi) east of Kaunas. Its main purpose is to provide grid energy storage. It operates in conjunction with the Kaunas Hydroelectric Power Plant. During periods of low demand, usually at night, Kruonis PSHP raises water from the lower Kaunas reservoir to the upper one using cheap surplus energy. The station is designed to have an installed capacity of 1,600 MW but only four 225 MW generators are currently operational. With a fully filled upper reservoir the plant can generate 900 MW for about 12 hours. The KPSP uses hydro-resources of artificial water pools existing at different geographical levels. The electricity from this power plant is supplied to a 330 kV electricity line to Elektrėnai, where the largest fossil fuel plant in Lithuania is operating, and Kaunas. During a surplus of electricity generation, the KPSP uses the surplus electricity to pump water from the lower pool to the upper pool. During an electricity output deficit, the Kruonis PSP operates as a regular hydro power plant, letting water flow from the upper pool to the lower pool to generate additional electricity. With a fully filled upper reservoir the plant can generate 900 MW for about 12 hours. Kruonis Plant is the only pumped-storage station in the Baltic states.The Kruonis PSP Industrial Park and Kruonis Technology Park were created as the location, infrastructure and low electricity price are attractive for data centers.A neighbourhood for workers of the Kruonis pumped storage plant plant was built in the 1980s and early 1990s in Elektrėnai, expanding this city of specialists in energetics by area and inhabitants roughly twice.

          Interesting! Still way too much elevation needed to be useful for us in Holland though. 😆

      If every home was a battery instead of an armory that would be a really cool redundant storage infrastructure. Likely not financially viable compared to centralized storage but it would be kind of cool if their was no immediate central reliance on power so any interruption in power generation could withstand say 1 week of storage reserves nation wide before outages started trickling off to support say hospitals, heating above 40 degrees, etc. Entirely too complicated I’m sure but just a neat thought I had after reading your comment.

        It does not make sense to compare the price of energy storage (lithium batteries), with the price for generating electricity (nuclear energy), or do you mean something else?

          People have a hard-on about nuclear being “baseload” power and renewables being intermittent. Solar/wind plus batteries to add dispatchability is a valid comparison to nuclear if you only want to talk about baseload.
