Proton Exchange Membrane (PEM) electrolyzer system
PEM is the natural choice for our
future renewable energy system
• Incredibly fast start-up and
shut-down
• Highest operational flexibility
• Cold start capability
PEM is clean by nature
• No CO2 emissions, unlike SMR1,
which emits 8-10 kg CO2 for each
kg of hydrogen
• There is nothing except water,
hydrogen and oxygen in the system
• Highest hydrogen purity >99.9%
• Oxygen as the only “contaminant”
• No aggressive chemical electrolyte
(e.g. KOH in Alkaline systems)
PEM is competitive
• Competitive hydrogen price per kg
at green electricity prices below
3 ct/ kWh
• Small footprint compared to Alkaline
systems
• Significantly lower OPEX2 compared
to Alkaline systems due to
maintenance-free stack
1) SMR: Steam Methane Reforming; 2) OPEX: Operational Expenses
