Energy storage liquid cooling related standards

What are the minimum energy performance standards for industrial cooling equipment?

New industrial cooling equipment must meet new minimum energy performance standards (MEPS). Process chillers must meet Seasonal Energy Performance Ratio (SEPR) metrics and comfort chillers must meet new Seasonal Energy Efficiency Ratio (SEER) values.

Are liquid air energy storage systems economically viable?

“Liquid air energy storage” (LAES) systems have been built, so the technology is technically feasible. Moreover, LAES systems are totally clean and can be sited nearly anywhere, storing vast amounts of electricity for days or longer and delivering it when it’s needed. But there haven’t been conclusive studies of its economic viability.

Could liquid air energy storage be a low-cost option?

New research finds liquid air energy storage could be the lowest-cost option for ensuring a continuous power supply on a future grid dominated by carbon-free but intermittent sources of electricity.

Is LCoS a good option for liquid air storage?

On that measure, the LAES technology excels. The researchers’ model yielded an LCOS for liquid air storage of about $60 per megawatt-hour, regardless of the decarbonization scenario. That LCOS is about a third that of lithium-ion battery storage and half that of pumped hydro.

What is long-duration energy storage?

Some methods of achieving “long-duration energy storage” are promising. For example, with pumped hydro energy storage, water is pumped from a lake to another, higher lake when there’s extra electricity and released back down through power-generating turbines when more electricity is needed.

What is levelized cost of Storage (LCOS)?

As a result, a different measure — the “levelized cost of storage” (LCOS) — is typically used to compare the costs of different storage technologies. In simple terms, the LCOS is the cost of storing each unit of energy over the lifetime of a project, not accounting for any income that results. On that measure, the LAES technology excels.
