An anonymous reader writes: One of the major issues with renewable energy technologies like solar and wind power is that energy generation tends to be intermittent — i.e. the sun doesn’t always shine and the wind doesn’t always blow. Therefore, in order for such technologies to be capable of meeting our needs without the support of fossil fuels, we need to find effective and commercially viable ways to store energy. Highview Power Storage recently unveiled a new tech that holds great promise for energy storage — the CryoEnergy System (CES). CES takes excess energy generated and uses it to run refrigeration units which cool air down to a temperature of -196C (-320.8F), at which point it liquefies. The liquid air, also known as cryogen, can be stored in an insulated tank, and at times of peak-demand, when the direst output of existing energy sources cannot meet the demands of a power grid, this liquid air is released to generate energy.
