Energy Required to Compress Oxygen into a 10mL Canister up to 60 bar: Isothermal vs. Adiabatic Limits

This technical brief evaluates the energy required to compress oxygen into a 10 mL rigid canister at 60 bar. Using ideal gas assumptions, the isothermal work is approximately 246 J, while the reversible adiabatic work is around 333 J. Accounting for real-world compressor inefficiencies (40–60%), the electrical energy per fill ranges between 400–800 J. The paper outlines key assumptions, compares thermodynamic pathways, and includes safety considerations for high-pressure oxygen storage. This analysis supports safe, small-scale experimentation with pressure-driven energy systems.
