Food Security via Clean Energy

Alex Lightman

The talk will show why food security is as important as national security, and how the transition from brown NH3 to green NH3 (produced with renewable energy and without carbon) is necessary for food security. This transition will set the stage for green NH3 to be used for energy storage and then a fuel source.

Ammonia as an Energy Carrier for Renewable Energy

Ken-ichi Aika

At present, ammonia is mostly formed through reforming of natural gas (CH4). A 1,000 ton per day plant is said to consume about 35 GJ of natural gas to produce 1 ton of ammonia (22.5 GJ of enthalpy). About 50% of extra energy is wasted. If 1 ton ammonia is produced through water electrolysis, 22.5 GJ of electricity is necessary theoretically. Here again, extra electric energy must be wasted. The author discusses roughly how the efficiency depends upon the process size and the renewable energy cost.
