Compressed Air Basics
storage costs are already below the 2020 targets, compression costs—which comprise 55% to 65% of CSD—are unlikely to decrease by 50%, which is the estimated cost reduction needed to meet the targets. The future version of the HDSAM model projects that capital costs for the compressor will drop significantly while …
By Ron Marshall Something about the compressed-air-system energy equation doesn''t appear to add up. Compared to what goes into the compressors, little energy is delivered at the far end of the system. Figuring It Out To realize the impact of this, you must do some calculations. Let''s take a vane-style air motor as an example, […]

Recovering compression waste heat using latent thermal energy storage (LTES) is a promising method to enhance the round-trip efficiency of compressed air energy storage (CAES) systems.
Thus: a system where we heat the air for an air engine (heat added to keep it isothermal) - 1.5kWhr is the available energy. A 33% effcient air engine gets us 500Whr. This is not bad, worth pursuing. Essentially: 1/2kWhr of storage for a $300 tank cost. This
Our base case for Compressed Air Energy Storage costs require a 26c/kWh storage spread to generate a 10% IRR at a $1,350/kW CAES facility, with 63% round-trip efficiency, charging and discharging 365 days per year. Our numbers are based on top-down project data and bottom up calculations, both for CAES capex (in $/kW) and CAES efficiency (in …
