PtX‐Plus: Synergies Through Coupling of PtX Facilities with a Biorefinery

In order to meet the climate targets, both the German Federal Government's National Hydrogen Strategy and the EU Commission's Green Deal [2] rely on so‐called green hydrogen. Conversion to hydrogen and chemical products (Power‐to‐X, PtX) is ideal for storing volatile amounts of electricity from wind and solar energy. If suitable biocatalytic facilities are added to this route, the product range can be controlled such that – under suitable boundary conditions – the production network can be operated economically, while adding value to unit operations that are already installed (Power‐to‐X‐Plus, PtX‐Plus). Biotechnological processes could complement the conversion of renewable energy into hydrogen and chemical products (Power‐to‐X) in such a way that the resulting production network can not only be operated economically, but can also add value to existing plants (Power‐to‐X‐Plus).
