Aspects of Ammonia as Green Fuel for Propulsion Systems of Inland Water Vessels
Energy Technology, Volume 13, Issue 2, February 2025.Within the CAMPFIRE project, an ammonia‐powered propulsion concept is being developed for use in inland water vessels. The core of the system is an ammonia‐fueled high‐speed engine that drives a generator. A cracker splits some of the ammonia into hydrogen and nitrogen to ensure better ignition and efficient combustion.
