The problem is that this design has competition from other methods of energy storage which are generally preferable. A pressure-storage system inherently needs two tanks, one for the liquid under pressure and one for the liquid not under pressure, so for starters you''ve made it larger. For mechanical energy storage, flywheels
"Storage" refers to technologies that can capture electricity, store it as another form of energy (chemical, thermal, mechanical), and then release it for use when it is needed. Lithium-ion batteries are one such technology. Although using energy storage is never 100% efficient—some energy is always lost in converting energy and
