The MethQuest research project is about creating new processes for generating renewable gas fuels andprogressing existing technologies. The MethMare group is working on propulsion systems for ships usingthese fuels. A very promising marine gas engine concept is the direct injection of methane with a small amountof diesel for ignition whereby unwanted methane slip remains negligible. Therefore a cryogenic high pressurefuel gas system with safe and high dynamic system performance is needed.At the ILK in Dresden, a container-based test bench has been designed and built to emulate the methane gassystem with nitrogen at a pressure of more than 400 bar, a mass flow of up 500 kg/h and the needed highdynamics in pressure and mass-flow load. The performance of the system, including a cryogenic high-pressurepump and a special double tube safety heat exchanger have been investigated. The measurement results areshown and compared with simulation data for the system setup. An outlook to future prediction of systembehaviour and application is given.
