Compressed-air is a versatile commodity for energy storage and automation. Compressed air is a vital part of pneumatic systems.

Storage in Caves

Natural caves and lava tubes are possible locations for compressed air storage. If the walls are lined with an impermeable membrane, the structure of the surrounding rock may be sufficient to contain the pressure. The entrances to the cave or tube are the only areas that need to be strengthened. Compressed air storage can be about 40% efficient in the best conditions. Some forms of adiabatic compressed air storage might reach about 70%.[1]


Methods to manage condensation must be included in any design, and may even be integrated into ISRU plans.
