The initiative – GET H2
To establish the core for a nationwide hydrogen infrastructure in order to make an efficient implementation of the energy transition possible. This is the goal of the GET H2 initiative. The initiative was launched by the companies RWE Generation SE, Siemens, ENERTRAG, Stadtwerke Lingen, Hydrogenious LOHC Technologies, Nowega as well as Forschungszentrum Jülich and IKEM – Institute for Climate Protection, Energy and Mobility.
The vision – A nationwide H2-infrastructure for Germany
Germany has set itself the target of reducing CO2 emissions by 80-95 percent (compared to 1990). In order to achieve this, further key technologies are needed in addition to the expansion of renewable energy generation and the electricity infrastructure. The conversion of electricity generated by renewable energies into hydrogen (H2) – power-to-gas – is a decisive factor. Together with the transport and storage of H2 in existing infrastructures, this creates a key to a successful energy transition. GET H2 is focusing on the development of a nationwide H2 infrastructure with the coupling of all sectors. The goal is to combine regions with a high share of renewable energies from wind and solar sources with H2 production on an industrial scale.
The principle is easy:
- Electricity from renewable energies is converted to H2.
- The green H2 is distributed via the existing gas infrastructure.
- In the industrial, transport and heating sectors, green H2 is used as a CO2-free energy source. In industry, it replaces H2 produced from fossil fuels.
- H2 that is not used directly is stored efficiently in existing underground storage facilities.
- During dark doldrums or winter times H2 can be used for re-electrification in a gas turbine.
The following graph shows an abstract representation of a possible course of the nationwide H2 infrastructure. Concrete courses, which mainly work with existing infrastructures, are being planned.
Necessary political support for green H2
The market launch of green H2, the establishment of an H2 infrastructure, the realization of the advantages of PtG technology, the establishment of a new economic sector – all this can be achieved with the support of a comprehensive package of measures:
- Adaptation of the tax and levy system to sector coupling requirements
- Maintaining or expanding incentives for green H2 technologies and their use
- Consistent consideration of H2 in EnWG, directives and gas market regulations
- Implementation of tradable guarantees of origin that provide information on the decarbonization contribution of H2 and can be offset against CO2 reduction targets – preferably CertifHy
- Supplement of the technical rules and regulations (DVGW) for pure H2 infrastructure
- Supplementing the Gas Network Development Plan for the transparent development of H2 infrastructure
