Current hydrogen applications: • Petrochemical industry

o hydrodealkylation o hydrodesulfurisation o hydrocracking

• Chemical industry o hydrogenation o chemical production (e.g ammonia & methanol)

• Metallurgy o shielding gas

• Semicon industry • Electricity production

o coolant in gas turbine

Annually > 70 million ton of hydrogen is utilized ~ 2% is produced by water electrolysis
