you’ll recall how the Snowy hydro scheme works by pumping water higher during periods of low electricity demand then releasing it during high demand periods. So simple, so effective, but unfortunately it’s likely coal-fired power that’s used.
same concept, different technology: the Chinese are doing it with compressed air, which is stored during periods of low power demand, then used to rotate generators when demand picks up, according to a report on Google News feed today.
air can be compressed during periods of low power demand. It’s just like a battery, except it’s compressed air.
for me, it’s face palm slap: the idea was just sitting there, in plain view.
