PRODUCTION CAPACITY HYDROGEN ENERGY SYSTEMS Production Capacity § Colocation into new production facility § Manufacturing space increased by 5 x § Adoption of semi-automated stack component preparation § Increase of power on-site to allow testing of larger systems § Heads of terms agreed § Costs in-line with expectations Production capacity in the current S 2 facility Production capacity based on standard 10 MW stack skids and 2 MW standard modules

PRODUCTION CAPACITY HYDROGEN ENERGY SYSTEMS ITM Electrolyser Cost Projections § Expect system sizes to grow over time § Larger scale enable cost reduction § Larger volume enable efficiencies § Continuous technology improvements § Sensitive to scope of supply <€ 1, 000/k. W today @ MW scale | <€ 800/k. W @ 10 MW | <€ 500/k. W by mid 2020’s

ELECTROLYSER SYSTEM COST CONSIDERATIONS HYDROGEN ENERGY SYSTEMS ITM Electrolyser Cost § Op. Ex more important than Cap. Ex § Example TCO for 10 MW system: Capex is 15 -25% of TCO Total Op. Ex is 75 -85% Electricity price is 80 -90% of Op. Ex • Cost of electricity is primary factor for cost of hydrogen ($/kg) Cost reduction will come via volume manufacture BUT more important is Power density of systems to reduce capex and net price of electricity. Factors of total cost of ownership
