Ocean water is going to be turned into lithium for LiFePO4 cells bank on it.
There is on avg 10kg of metallic lithium in a 80kWh pack. The Saudis have a way to get lithium metal from water at $5 per kg of Lithium in energy costs with the byproducts worth more than the lithium itself. Check out the science in my other post.
I also have solar panels my leased model S was getting the equivalent of 27 cents per gallon in fuel costs buying back off peak power. Texas is a netmeter State I could have got those kWh back in a net meter agreement at zero cost but I’d rather sell peak power during the day directly to ERCOT and then buy back whole sale power at night for the TDU charge plus whole sale rate which I can get at for 3.2 to 3.6 cents almost every night.
Even without ocean lithium there is so much in the shale well flow back brines that the USA will never run out. UT Austin is already commercializing their tech to do just this.
That’s pretty awesome and clever.
