Real-Time Power Supply for eFuels (RePoSe)
According to scientific and political consensus, the production of power-to-liquid (PtL) only makes ecological sense if renewable electricity is used. The challenge with so-called "green" electricity, however, is that in Germany the energy generated in this way is not continuously available, as it is mainly obtained from wind power and photovoltaic systems. There is a need for further expansion here. The RePoSe project is dedicated to the goal of researching the operation of a power-to-liquid plant with variable power availability and supply and to verify the theoretical concept on the basis of the practical operation of such a plant.
Essential aspects to be investigated are the optimization of the size of the hydrogen buffer storage, the effects of different current profiles and the use of short-term power forecasts for the control of the entire plant and the interaction of buffer storage and semi-variable production, the analysis of the degeneration of functional materials and the analysis of the stressed system components from the real use phase with regard to aging and damage mechanisms.
