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. Behind the initiative are companies and institutions that are actively committed to creating a competitive hydrogen market and to making the necessary adjustments to the legal and regulatory framework. In several projects, the partners of the initiative are driving forward the development of the technologies and their market launch and are planning the implementation of infrastructures for the production, acceptance, transport and storage of green hydrogen (H2).
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 (wind and sun) is converted into H2.
- H2 is transported via a separate infrastructure, for whose development the existing gas infrastructure is used.
- In the industry, transport and heating sectors, green H2 is used as a CO2-free raw material, fuel and energy source. In industry, it replaces, among other things, fossil generated H2.
- Green H2 is used as the basis for the production of e-fuels, especially for aircraft and rail vehicles.
- H2 not directly used is efficiently stored in existing underground salt caverns.
- In times of darkness, when no wind is blowing and no sun is shining, the H2 can be used for re-electrification, e.g. via 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.
