Correct. It will take around 10-20 years for this happen at current scaling of grid storage. In the meantime it doesn't make sense to scale up new gas, coal, or nuclear, as they won't have a decent ROI over their lifespan.
- pabs3 2y agoAt least in Australia, the oversupply of rooftop solar is already getting to be enough of a problem that its a signal to investors that getting into grid scale batteries could be profitable, and to home owners that house scale batteries are a good idea.
- h0l0cube 2y agoSodium-ion battery packs are starting to enter the market, and are already quite cheap. I think within a couple of years the economics will be difficult to resist.
- defrost 2y ago> and to home owners that house scale batteries are a good idea. There's a middle ground to exploit for business that I've seen few (although some) examples of in Australia - "neighbourhood" batteries that cover 200 homes or so. Good for small towns, developments, suburbs, etc - about $1 million (AUD) as I recall, decent economics - work with grid provider to soak charge container sized battery from surrounding solar, feedback on demand, etc.
