The energy transition is considered a catalyst for the supply of clean, secure and affordable energy in Germany. In the fight against climate change, hydrogen made with renewable electricity (green hydrogen) is increasingly regarded as the solution for the decarbonisation of industry sectors with particularly high emissions, such as heavy industry and aviation. Green hydrogen is also regarded as an alternative to the support for carbon capture and storage (CCS), which is required when producing hydrogen from natural gas.
Germany has ambitions to become a leader in green hydrogen associated technologies, and the German Government recently published its National Hydrogen Strategy (NWS) setting out its plans to fulfil these ambitions. But what is the current state of play and what are the Government’s plans to implement the NWS.
Hydrogen will play a key role in the energy transition in Germany and in Europe. The German Government is committed to supporting both the development of the hydrogen infrastructure in Germany and also across Europe, however, the German legal framework has yet to fully reflect this commitment. Decarbonisation of the German energy mix is also costly and the Government will want to make sure that sufficient incentives are created for investors.
PRODUCTION OF HYDROGEN IN GERMANY
1Green hydrogen is zero carbon hydrogen produced through electrolysis using renewable energies.
TRANSPORT AND STORAGE OF HYDROGEN IN GERMANY
USE OF HYDROGEN IN GERMANY
Possible applications of hydrogen include rail transport, road transport, aviation, shipping and other industries:
In rail transport, hydrogen is particularly attractive for tracks that have no overhead contact line
In public road and freight road transport, hydrogen would also prove advantageous in comparison with electric vehicles as the charging times and weight of the batteries needed for electric vehicles are not always economically feasible
For road travel, there are currently only a total of 87 hydrogen filling stations across the country. The German Automobile Club ADAC estimates that about 1,000 stations are required to secure nationwide supply
Thyssen-Krupp is aiming to produce climate-neutral steel by 2050 and has begun a project on the use of green hydrogen in blast furnaces. In cooperation with RWE, the transportation of green hydrogen from Lingen is envisaged once the hydrogen network is established
Uniper wants to increase the use of hydrogen in electricity production and, in cooperation with Siemens, is examining how gas power plants can become more environmentally friendly. Converting excess green electrical energy into energy-rich hydrogen and methane that can be stored and then used to power fuel cells can help with the energy turnaround
THE FEDERAL GOVERNMENT’S STRATEGY
On 10 June 2020, the German Government adopted its national hydrogen strategy NWS:
According to the NWS, only green hydrogen is sustainable in the long term and should therefore be promoted by the NWS. Due to Germany's close integration with the European energy supply infrastructure however, and in view of the increase in demand for energy in Germany, CO2-neutral hydrogen (blue2 and turquoise3 hydrogen) may also be used, at least temporarily.
By 2030, hydrogen production plants with a total capacity of up to 5GW are to be built. By 2035, and at the latest 2040, 10GW should be installed. These projections were the subject of controversial discussions that continued up to the end of the NWS negotiations and it cannot therefore be excluded that these figures will be adjusted in the future.
The Government expects that about 90TWh to 110TWh of hydrogen will be needed in Germany by 2030; 5GW corresponds to a green hydrogen production of 14TWh, for which 20TWh of electricity from renewable energies is required. As hydrogen demand cannot be met through domestic hydrogen production alone, the further demand will need to be covered through imports. The potential for the production of hydrogen in other countries should therefore be developed, especially within the EU.
It is envisaged that green hydrogen production will be exempt from the EEG levy; it must be ensured that the levy does not increase as a consequence.
Opportunities for new businesses and cooperation models between operators of electrolysers and TSOs in line with the regulatory unbundling regime will be developed.
A further objective under the NWS is the exploration of potential tendering schemes for the production of green hydrogen, e.g. to help decarbonise the chemical and steel industries.
In an initial reaction to the NWS, the German Chamber of Industry and Commerce criticised the exclusive commitment within the NWS to green hydrogen, and demanded more openness towards blue and turquoise hydrogen as it is considered green hydrogen cannot cover the potential demand for hydrogen in Germany in the foreseeable future.
On 3 June 2020, the federal cabinet (Bundeskabinett) passed a draft of the Wind Energy at Sea Act (Windenergie-auf-See-Gesetz), which envisages the possibility of constructing offshore wind farms that do not require connection to the electricity grid. Instead, the electricity generated in these offshore wind farms is to be used directly at sea without using the grid, e.g. through the operation of an offshore electrolysis plant for the production of green hydrogen.
Although the construction and operation of offshore electrolysers is much more expensive compared to onshore facilities, the additional cost is compensated by the saving in investment costs for connection to the electricity grid. Such electrolysers could also be operated using other facilities including oil and gas platforms.
2Blue hydrogen is hydrogen where the emerging CO2 is captured and stored during its production.
3Turquoise hydrogen is hydrogen that is produced by the thermal cracking of methane and solid carbon is produced instead of CO2
