Calculations for a 1kWhr System
- From Compressed Air Energy Storage results, it takes 170 cubic meters of air to deliver 1kWhr of usable stored energy.
Calculator
See https://www.tribology-abc.com/abc/thermodynamics.htm
According to the calculator, a 50 l tank of air at 3000 psi will release about 0.5kWhr via adiabatic expansion, and 2.5x this with isothermal expansion.
Cylinder Sourcing
- Firefighter supply - 300 cf $300 [1]
- 250 cf - $285 [2]
- 250 cf = $330 [3] K size?
- T-size 300 cf - [4]
- T goes up to 390 cf - [5]
Compressor
- Scuba compressor - $243, 1800W - [6]
