China is doing so many big things with their power infrastructure recently, they’re obviously very keen to get away from oil
I like that its green, but is really more strategic on their part. China has just a small fraction of domestic petroleum production of other countries like the USA or Russia. This means China is vulnerable to other countries that they depend on for petroleum imports to feed their people and produce economically.
Every effort to shift energy production (and storage) to domestic ways means less dependence on other nation’s energy exports.
Why though? The main benefit of solid state is the energy density, which is not at all important for a stationary, grid-connected system. It’s also super expensive. Why not just stick with sodium-ion batteries for the grid which are way cheaper per kWh?
“A single charge can store up to 200,000 kWh of electricity, brining the annual discharge to more than 60 million kWh.”
You know, we do have SI prefixes too. They are also free to use.
Sadly we can’t buy that things yet for home or office bc it’s still expensive
