Zero emission aircraft: ammonia for aviation

This week, Reaction Engines announced a “ground-breaking study” on ammonia as a fuel for zero-emission aircraft. This will soon be followed by a demonstration project, “integrating the technology into a ground-based test engine.” The study combines Reaction Engines’ heat exchanger technology with the ammonia cracking technology being developed by the UK’s Science and Technology Facilities Council (STFC). By partially cracking green ammonia to hydrogen, the resulting ammonia fuel mix “mimics jet fuel,” making it possible to adapt existing engines and aircraft to use zero-emission fuels. “This means a fast transition to a sustainable aviation future is possible at low cost.”

Carbon Free liquid fuel for tomorrow’s piston and turbine generators

In the 1960s the US Army and University of California modified and flew military helicopter and fixed-wing turbine aircraft by burning pure ammonia. The plan was to generate NH3 from local air & water in remote locations, sparing little expense by modifying only the engine’s firebox and air intake. We’re all here to reduce the cost of air travel, placate noise complainers, and grab our share of the massive growth of future airline cash-flow. Nonsense. The real goal is not fuel efficiency but Carbon-free air travel; electric-hybrids with current engine-generators. Americans bought 6,000,000,000 pounds of liquid NH3 last year.
