  • Why the water isn’t killing the fire?

    Could be anything from sodium to calcium carbide to fluorine. :) Sodium makes hydrogen with water, carbide makes acetylene with water, and flouride just oxidizes water by grabbing hydrogen away from oxygen.

    If the character’s plan is to try fascism next, I think they’re into fairly agressive substances. :P


  • I mean sure, if you’re at such extreme latitudes that you have months of total darkness, then solar will have a problem there. Maybe small modular reactors make sense for those niche applications.

    Currently, solar still makes economic sense, but from April to October. Lots of it was built rather fast, now the adoption is slowing since the grid can’t accept it everywhere.

    Consequently, summer is when oil shale miners rest and prepare for the next season.

    Since the goal is to get rid of mining oil shale, big plans exist to install a lot of wind power. Sadly, this has gone embarrassingly slow, and it cannot cover winter consumption, and there is not enough storage.

    As a result, some companies and building out storage, but only enough to last a few hours.

    …and in the next country southwards, there is a huge gas reservoir that could accept methane, enough to last the whole winter, but nobody has a good enough handle on methanation to renewably produce a considerable quantity and store it there. :o

    With regard to reactors, it seems likely that getting one would take 10 years and the local country here doesn’t even have legislation built out for nuclear power. They’re drafting it. Starting from zero is quite slow.



  • Since 2021, nearly 4 full years, the world has closed less than 1% of active coal power plants.

    Closing will come later, when alternatives are widely available. What renewable energy does currently - at least here - is forcing those plants temporarily out of the market, especially during summer months and windy weather. The plants will exist and stay ready in case of need for well over a decade, maybe even two - but they will start up ever more rarely.

    Technically, the deal is: we don’t have seasonal energy storage. Short term storage is being built - enough to stabilize the grid for a cold windless hour, then a day, then a week… that’s about as far as one can go with batteries and pumped hydro.

    To really get the goods one has to add seasonal storage or on-demand nuclear generation. The bad news is that technologies for seasonal storage aren’t fully mature yet, while nuclear is expensive and slow to build. There’s electrolysis and methanation, there’s iron reduction, there are flow batteries of various sorts, there’s seasonal thermal storage already (a quarter step in the right direction)…

    …but getting the mixture right takes time. Instead of looking at the number of closed plants, one should look at the sum of emissions. To remain hopeful, the sum should stop growing very soon.
