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
