> But I've never heard that batteries are not "scalable," when they are actually one of the most incredibly scalable technologies out there. Want a few watt hours? No problem. Want 10GWh? No problem. Want to distribute a MWh at every distribution station across a country? No problem. Its actually massively difficult challenge both from a production and supply chain perspective. Lithium itself plentiful but getting it into the battery is a long way. Its more like specialty chemicals, even the 'Lithium majors' have had massive problems getting new plants online and producing high quality lithium. Battery plants are incredibly complex mass manufacturing operations and even small manufacturing problems can leave to burning cars. Scaling these is very difficult and only a few companies are really producing lithium batteries at scale. Lithium batteries in Grid operation have never been deployed at '10GWh' so if it was 'no problem' then somebody might have done it. The challenge of producing enough batteries (and renewables), lithium or otherwise to have a 100% reliable electricity grid (even if there are 2 weeks without wind) is gigantic and to me it actually seems far harder then just building nuclear plants. > Coal is already a dead man walking. Look at China, India and Indonesia and then rethink your statement. It just so happens that US and Western Europe are not the only places in the world.
