Kostnad för Liquid-air storage

Kostnaden för Liquid-air storage ligger runt 90 öre per kWh idag. Om 10 år kanske man är nere på 45 öre per kWh.

For a 100MW system, we are already touching [a levelized cost of storage (LCOS) of] $100 per MWh today,” chief executive Javier Cavada tells Recharge. “In ten years from now, I can see that being $50/MWh. That's very doable.”
By comparison, a new pumped-hydro plant would have an LCOS of $152-198 per MWh, with a comparable lithium-ion system costing $285-581/MWh, according to analyst Lazard.
With a new gas-peaker plant having a levelized cost of energy of $156-210/MWh, and wind power at $30-60/MWh (according to Lazard), it may already cheaper to balance the grid using wind-powered liquid-air storage than fossil-fuel technology. And if the LAES system is “charged” using wind power that would otherwise be curtailed, the wholesale price of that power would be close to zero.
And renewables backed up by LAES could soon be cheaper than new dispatchable coal-fired power plants, which currently cost $60-140/MWh (according to Lazard).
In 2022, we will be building 20 [liquid-air storage] plants of 100MW each,” says Cavada. “We will be the biggest energy-storage company on the planet, that’s for sure.”
