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.
Rough Calculations
- Air tools require 30 cfm for 1 hp [1]
- 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. Not great, but we can get much better efficiencies from a better air engine.
Air Engine
- Rotary air engine - [2]
- 0,75 hp $200 30 cfm [3]
- Rotary vane, 1.8 hp $200 [4]
- Radial Piston Motor - 20x more efficient at full load than rotary! [5]
- Radial vs axial piston motors - [6]
Cylinder Sourcing
- Firefighter supply - 300 cf $300 [7]
- 250 cf - $285 [8]
- 250 cf = $330 [9] K size?
- T-size 300 cf - [10]
- T goes up to 390 cf - [11]
Compressor
- Scuba compressor - $243, 1800W - [12]
Technical
- Compressed Air Index - [13]
