To be able to operate positive energy districts (PED) in an energy- and resource-efficient manner, technologies are necessary that manage the generation, storage and use of renewable energy as required.
Reversibly operated high-temperature fuel cells (rSOC) can be seen as a link between electricity, heating and gas grids. In fuel cell mode, they enable the highly efficient production of electricity and heat (e.g. from natural gas) and, in electrolysis mode, they offer the possibility of producing hydrogen.
The rSOC technology can make a significant contribution to the efficient use of fossil fuels and the expansion of regenerative energy systems. In order to accelerate their commercialization, however, reliability and durability must be increased, among other things.
The overarching goal of CELL4LIFE - the development of economic operating and business models for the use of rSOC technology in neighborhoods - is to be achieved through the following procedure:
- Research into the optimal mode of operation to minimize degradation
- Development of a predictive control strategy with the inclusion of artificial intelligence
- Best possible use of existing supply and consumer infrastructure
- Determination of the maximum possible substitution of natural gas with hydrogen with decentralized feeding into the natural gas network
- Optimization of hydrogen production in an rSOC system
- Optimization of the transient operation of the rSOC system
- Demonstration of the system in the form of a laboratory prototype
