Ammonia Marine Engine CF08_2
Project duration: 04/2021–03/2024
Aim of Project:
On the way to implementing the energy transition, shipping must also be transformed into an emission-free and climate-neutral area of mobility. The use of “green” ammonia as a carbon-free fuel offers the potential to contribute to achieving this goal for future shipping. Against this background, the focus of the subproject is the systematic analysis and experimental testing of a novel ammonia cracker gas engine system suitable for the operation of an inland vessel.
In addition to developing an ammonia-hydrogen combustion concept, the project will also develop and verify an ammonia cracker for generating hydrogen from the ammonia for marine applications. Based on experimental investigations on a single-cylinder research engine, a suitable method for energy conversion in the propulsion engine is derived and optimized by accompanying simulation. On this basis, a full engine concept will be developed which, in conjunction with the developed ammonia cracker, will be transferred to a test facility and investigated for operation in an inland waterway vessel. In addition to the optimization of the plant operation and the determination of the operating limits, another focus is on the simulation-based optimization of the overall energetic system through the thermal coupling of the prime mover and the ammonia cracker. Based on the provided process simulation models as well as the experimental data of the individual systems and the overall plant, the proposed new drive concept will be finally evaluated from a technical and economic point of view. The project will create the basis for using “green” ammonia within climate-neutral shipping.
