Modular systems reduce business risk
● Cost $10M’s instead of $1000M● Add units as need increases● Deploy near end-use● Deploy near clean energy
VS
Increase number of modular units
Increase unit size
Two ways to increase capacity

Unit size & mass prod. reduce NH3 cost
● Assumes 65% CF, $0.01/kWh● Unit size dictated by capex and desired initial NH3 cost● Mass production continues to drive down cost

Synthesis tech refinement continues
● Lower capex membrane-less H2
● Variable-power membrane N2 ● Better adsorbent material & process● Capex – operating pressure – NH3 cost

“Rapid Ramp” demonstrated
● 75% H2, 25% N2
● Flow increased by opening recirculator throttle valve
● Rate follows flow very closely● Rate ramp rate = flow ramp rate
