Ammonia Fuel Uses1. Internal Combustion Engine (ICE)
– Diesel: NH3 gas mixed with intake air– Spark-ignition: 70%+ NH3 plus
gasoline, ethanol, propane, NG, hydrogen– NOx ~ ¼ gasoline engines
2. Combustion Turbines3. Direct Ammonia Fuel Cells:
– Combined heat + power (CHP)– No NOx
4. Reform (“crack”) to liberate hydrogen for fuel cells: 2NH3 3H2 + N2

NH3 Synthesis Plant Cost3,000 tpd NH3 = 675 tpd H2 @ 80% efficiency:
Need TWO plants for 2,000 MW windplant
• Industry sources:– 2,000 mtd NH3, NG source, all costs $500M– 2,200 mtd NH3, NG source, all costs $466M– 140 mmscfd H2 plant costs ~ $200M– NG conversion, all processes: ~ 60% of total capital cost– Delete NG conversion, must add N2 plant (ASP) (estim: $75M)
• 3,000 tpd NH3 plant, from renewable-source H2, costs:– NG conversion (SMR +) $ 0– H-B reactor $ 225 M– Balance Of Plant $ 75 M– Add Air Separation Plant, for N2 $ 75 M– Add H2 compressor (30 100 bar) $ 5 M
TOTAL $ 380 MTWO PLANTS $ 760 M

Opportunities• Collaboration
– International: “Run world on renewables”– RE systems: sources to end uses, firm and dispatchable– USA lead ? Korea ?– R&D– Demonstrations & pilot plants
• Solid State Ammonia Synthesis (SSAS)– RE electricity + water + N2 NH3
– Proof-of-concept pilot plant– Technical + economic promise?– Several processes ?
• NHThree LLC patented PCC• Hydrogen Engine Center lithium• Other ?
• End use: stationary, transportation, fertilizer• Commercialization

Humanity’s Goal A global, sustainable,
benign-source, equitable, energy economy
• CANNOT with only electricity transmission
• “Transmission” must includeGH2, NH3, other

Beyond “Smart Grid”• Primarily DSM• More vulnerable to cyberattack ?• Adds no physical:
– Transmission, gathering, distribution– Storage
• Next big thing; panacea• Running the world on renewables ?• Must think:
– Beyond electricity– Complete energy systems
