Spark-Ignited Ammonia Engines and Gensets
The Hydrogen Engine Center (HEC) is developing ammonia-hydrogen and ammonia-propane spark ignited engines, with the goal of achieving a super-efficient 100% ammonia engine in the near future.
HEC currently is operating an ammonia-propane engine in California which is powering an irrigation system.
