Some of the more likely routes, with clearer cheaper cost curves than advanced nuclear or SMRs:&lt;p&gt;1) advanced geothermal (using drilling tech developed within the last decade, not the older ones)&lt;p&gt;2) flow batteries&lt;p&gt;3) chemical storage of electricity, whether as ammonia, hydrogen, methanol, or whatever tech path becomes cheapest.&lt;p&gt;4) for cold climates: district&amp;#x2F;neighborhood heating with massive seasonal storage&lt;p&gt;All of these are being developed, and experiencing falling prices on the tech. In contrast, building the same nuclear reactor design gets more expensive successive time it is built.  This is true even of France&amp;#x27;s builds in 70s.&lt;p&gt;If we are betting on future tech, nuclear is not in the cards. It would have been great it nuclear had put coal out of business in the 1980s, rather than having a ton of build delays in the 1970s that jacked up nuclear&amp;#x27;s price. But it&amp;#x27;s ship has sailed, until nuclear can build.&lt;p&gt;If France completes a single reactor by their planned 2035 date, I will be seriously impressed. However, 1GW in 13 years is not a climate solution.</text><parent_chain><item><author>visarga</author><text>Once a few years, we get a few weeks without much wind and solar. What do we do then?

There is constant exchange of excess energy between the countries anyway. Regardless of that, there are other options too. Like water or geothermal depending on the country. Sometimes there even will be too much energy. I can imagine this being used to make some hydrogen for later use.</text><parent_chain><item><author>visarga</author><text>Once a few years, we get a few weeks without much wind and solar.
