The specific power for a fixed-speed compressor is measured under laboratory conditions on a lossless system with the compressor fully loaded (its most efficient point). This is not typically a real-life situation. In real life, a plant air system has some losses that need to be considered.
(Specific power is like a gas-mileage rating for compressors, calculating the energy input compared to the flow output.) If we do a little calculating, we find that the 30 cfm required by the one hp air motor will cause the air compressor to consume 7.5 kW, about 10 times as much as the motor power output. But the story gets worse!
Compressed-air energy storage can also be employed on a smaller scale, such as exploited by air cars and air-driven locomotives, and can use high-strength (e.g., carbon-fiber) air-storage tanks.
The design exergy efficiency and NPV of the system are 66.99 % and 12.25 M$. Compressed air energy storage (CAES) is one of the important means to solve the instability of power generation in renewable energy systems.
Compressed-air-energy storage (CAES) is a way to store energy for later use using compressed air. At a utility scale, energy generated during periods of low demand can be released during peak load periods. The first utility-scale CAES project was in the Huntorf power plant in Elsfleth, Germany, and is still operational as of 2024.
implying that we can get 1kWhr power output from a single cylinder of high pressure air. A 300 cuf tank thus gives 10 minutes, about, of 1 hp power. With radial piston motor - at 10-20 the efficiency, easily gives 1 hp hr. Let's get specifics. 6 cylinders would thus give 1 hp hr.
