Compressed air energy storage (CAES) is an energy storage technology whereby air is compressed to high pressures using off-peak energy and stored until such time as energy is needed from the store, at which point the air is allowed to flow out of the store and into a turbine (or any other expanding device), which drives an electric generator.
During deflation, the air was released straight to atmosphere, as the aim of the test was just to exercise the Energy Bags and assess their design; obviously the high-pressure air released from an Energy Bag in an energy storage plant would enter an expander-generator set to generate electricity. Fig. 11. Pressure vs. time for the two bags.
Since the pressure of inlet air is higher than pressure in the cylinder, which makes the pressure gradient large and the airflow speed fast when the air enters the expander. Hence, this kinetic energy converts into internal energy in the cylinder, and the temperature rises rapidly.
The isothermal compression efficiency is increased 21.1 %, the compressor power is decreased 18.87 kW and the isothermality is increased 28 % as the ML increases from 0.5 to 15. This means that with more water droplets sprayed into the cylinder, the compression resembles an isothermal process more closely.
Hence, this kinetic energy converts into internal energy in the cylinder, and the temperature rises rapidly. After that, the inlet flow rate decreases, the piston moves downward, and the air releases heat to the residual droplets.
Conclusions This paper has described the design and testing of three prototype Energy Bags: cable-reinforced fabric vessels used for underwater compressed air energy storage. Firstly, two 1.8 m diameter Energy Bags were installed in a tank of fresh water and cycled 425 times.
