https://newatlas.com/energy/highest-density-lithium-battery
Tesla battery apparently have a density of 244-296 Wh/Kg, so does that mean 1000 metic tonnes of of batteries at 289.6 Wh would be enough to provide annual storage here? That doesn't seem infeasible or unreasonable for something potentially so beneficial.
Lithium battery is usually not what's is used for grid scale batteries. The new natrium batteries could do that and are made from far cheaper and more abundant materials. The energy saving concrete also promises to be a good solution when used instead of regular concrete and candy be built directly beneath renewable power plants.
Nice, sounds even better!
Over production of energy may well be cheaper than battery storage anyway
Terrawatt is 10^12 so 1000 tonnes of battery would give you around 200MWh of storage. To get to 2000 TWh you are looking at 10,000,000,000 tonnes of Li-ion batteries. For a bit of scale, thats like turning around 10% of mount Everest into battery.
