Using the above methodology, I ran numbers for a desalination factobattery and it's really bad, like two orders of magnitude more expensive than just buying a Li battery to buffer the unreliable energy and running desal 24/7.
- ChuckMcM 3y agoThis right here. Even low grade continual energy supply is better for desal.
- BurningFrog 3y agoBy "battery" here, I just mean a dam that holds a few days worth of fresh water.
- brilee 3y agoI think you misunderstood the comment. I agree there has to be a buffer somewhere. You're arguing that we can get a free buffer by piping the water behind a reservoir, but the cost is that the very capital-expensive desalination plant will be idle half of the time. I'm proposing that the more economical option is to buy a lithium ion battery to buffer the renewables and run the desal plant 24/7. (You can still pipe the water behind a reservoir if you want)

- BurningFrog 3y agoI see. It's better to have a half as big plant running 24/7 with a battery. Thanks for educating me!
