CENA Hessen is the project coordinator for RePoSe and is investigating the optimization of synthesis plant downtime and hydrogen storage sizing in this project. This includes obtaining and analyzing data on power availability from renewable generation, performing the optimization calculations, and the practical operation of a hydrogen storage facility.
As part of the project, Fraunhofer IWKS will investigate the system components replaced at specified intervals and their wear as well as any fatigue phenomena that may occur (cracking, surface damage) metallographically, structurally, microstructurally, and morphologically. This gives the opportunity to carry out targeted optimizations on the materials used and to investigate the effects from operation in combination with the effects of hydrogen.
Fraunhofer LBF is investigating the reliability of the system under variable loads. This includes the measurement and evaluation of local stresses on the plant, the derivation of fault-effect relationships for the evaluation of failure scenarios and their effects on the operating time as well as on plant efficiency and safety. Cyclic analyses of the polymeric and metallic materials used will be used to evaluate material degradation caused by the plant's contact media.
Ineratec GmbH plans to build a pioneering power-to-liquid (PtL) plant for generating e-fuels at Industriepark Höchst. It will produce up to 2,500 tons or 4.6 million liters of INERATEC e-fuels annually from up to 8,000 tons of biogenic CO2 and renewable electricity. The pioneer plant is made up of individual, standardized modules. One of these modules is to be incorporated into the RePoSe project in order to test a volatile power supply.
Provadis School of International Management & Technology AG will perform a life cycle analysis as part of the RePoSe research project. This will quantify the environmental impacts, such as the CO2 footprint and the use of resources, in detail and in relation to each process step. This makes it possible to identify at an early stage which process steps have a high environmental impact so that measures can be taken to reduce them. In addition, it can be deduced whether there are ecological advantages compared to continuous processes.
