Hydrogen from renewable sources plays a significant role for the envisaged decarbonization/defossilization of our energy system. Here, three basic functionalities can be distinguished:
1. Hydrogen as energy carrier and/or intermediate for mobility
2. Large-scale interim storage of energy and
3. Replacement of hydrogen and other educts obtained from fossil fuels and used in the raw materials industry and the chemical industry.
As the energy revolution progresses, the said measures together with other decarbonization measures, for example in the thermal area, are realised in a certain order. This order is determined, among others, by the specific CO2 savings of the respective measure (measured in tons of CO2 saved per renewable MWh) and the respective CO2 avoidance costs.
Structure of the research society
The above context leads to a very diversified need for research and development that is currently addressed by different actors around the world and particularly in Germany. Around 20 research teams from Lower Saxony are also involved in these endeavours that concentrate on the following six important focus areas:
