Current li-ion pricing is $19 per kwh (BYD's latest cell's pricing), so a single battery that covers all 4TWh would come in at 76 billion dollars. Still a shit ton but reasonable.
To get a sense of scale, when accounting for round trip efficiency of li-ion batteries and gravity batteries, a single 18650 battery has about the same energy as lifting 100kg by 50 meters. A single cell is about $5 in…
