Emission-free and highly emission-reduced rail traffic on non-electrified lines
The Bavarian Ministry of Economic Affairs, Regional Development and Energy is funding the research and development of the Liquid-Organic-Hydrogen-Carrier (LOHC)-technology for mobile use using the example of rail vehicle technology with over €28 million between 2019 and 2023 in order to achieve emission-free or highly emission-reduced rail traffic on non-electrified lines.
The aim is to refuel the train directly with the hydrogen-charged LOHC-carrier. The hydrogen is then released on board the train and converted into electricity in a fuel cell. One of the aims of the project is to adapt the equipment needed to release the hydrogen for mobile applications. In addition to on-board catalytic dehydrogenation, the researchers are also pursuing a particularly innovative approach: the development of a direct LOHC-fuel cell for mobile applications. The direct fuel cell generates electrical energy directly from charged LOHC. An additional apparatus for the catalytic release of the hydrogen gas on board the train would then be omitted.
