Evaluation of operation safety of energy release
Liquefied air energy storage (LAES) is an energy storage technology based on CAES technology, which uses liquid air for power storage [7, 8]. LAES technology overcomes the technical defects of traditional CAES, such as dependence on supplementary combustion of fossil fuels and limitation of special geological conditions.
Vacuum Energy Storage | DIY Solar Power Forum
That''s about $5,000 in concrete. If we stopped there it would be $84/kWh. Everything else is probably fairly cheap, let''s say another $5000 for the turbine, excavation (depends on terrain, could be as low as $400 for soft soil), plumbing, etc. So, $10,000 for 60 kWh storage, which brings us to $170 kWh storage.
