Load flexibility - the problem of a fluctuating energy supply

Both scientists and politicians agree that the production of synthetic fuels via power-to-liquid (PtL) processes only makes sense ecologically if regeneratively generated, green electricity is used. However, a fundamental problem with renewable electricity is that in Germany it is mainly generated from wind power and photovoltaic (PV) plants, where energy is not continuously available.  
Although it is generally agreed that these very fluctuations in energy supply must be taken into account, the economic and technical aspects have not been scientifically investigated to date. This is where the RePoSe project steps in:  
The research project RePoSe stands for Renewable Power Supply for eFuels and deals with the topic of load flexibility. Together with the two Fraunhofer Institutes LBF and IWKS, the Competence Center for Climate and Noise Protection in Air Traffic of the State of Hesse CENA and the Provadis School of International Management and Technology, INERATEC is researching and testing the operation of a PtL plant under the conditions of variable power availability and supply based on renewable energies. 
The aim is to investigate the essential point of fluctuation and variability of power availability in an industrial scale. This is to avoid mismanagement that would occur if these aspects were neglected. Furthermore, general knowledge on the operation of a PtL plant under the conditions of a variable power supply will be generated. 
Thanks to INERATEC's pioneer project in Frankfurt, we can offer this industrial scale: the module being researched in the RePoSe project is part of our e-Fuel pioneer plant. Of course, load flexibility is also of great importance for our plant in Frankfurt, in order to be able to operate it as efficiently as possible from 2024 onwards.  
Here you can see the foundation already poured for the plant unit used in the RePoSe project: 

Project RePoSe is funded with a total of 3.425.491 euros by the Federal Ministry for Digital and Transport as part of the Funding Programme Renewable Fuels. The funding guideline for the development of renewable fuels is coordinated by NOW GmbH and supported by the project management agencies VDI/VDE Innovation + Technik GmbH and Fachagentur Nachwachsende Rohstoffe e. V. (Agency for Renewable Resources).
