3. Sizing of Hydrogen Compressor
The compressor is chosen based on the requirements for the inlet and outlet pressures (30
bar inlet and 200 bar outlet) and gas flow rate (0.00262 kg/ s). Hence, taking a reasonable
efficiency value of 0.6, the rated power of the compressor will be 13.22 kW as obtained
by (23) as shown as follows:
The compressor will run whenever the electrolyzer is at work. The power to operate the
compressor will be derived from the PV modules.
