No dominant option for future German hydrogen imports – Researchers
No dominant option for future German hydrogen imports – researchers.
Germany will be able to procure the necessary volumes of hydrogen imports by 2030 if it quickly sets the right infrastructural, legal and entrepreneurial path, found a team of researchers from “Energy Systems of the Future” (ESYS). ) in an analysis.
The team looked at the different import options – from pipeline transporting the gas to liquefied hydrogen or shipping the fuel as ammonia – and found there was no alternative. dominant.
ESYS, which is an initiative of the German Academies of Sciences, writes:
All options have specific strengths and weaknesses as well as different implementation horizons and requirements, so they must ultimately be established on a case-by-case and application-specific basis.
For example, a system of import by shipment of green ammonia – to be used as a raw material for example in the chemical and fertilizer industry – could be put in place almost immediately. Large volumes of pure hydrogen could also be imported through refurbished gas pipelines within 3-5 years.
The transport of liquid hydrogen by ships is still far from being the case, however, say the researchers. They call this a “good option” from 2030, but point out that the necessary liquid hydrogen tankers are still in the development phase and that it is currently not possible to predict when large enough fleets of vessels will be available to commercial transport of liquid hydrogen.
The analysis is based on calculations on the costs and energy efficiency of the respective transport chains, as well as on qualitative criteria, including environmental impacts, existing infrastructure and political and legal feasibility.
In the fight against climate change, hydrogen made from renewable electricity is seen as an essential tool to decarbonize sectors with particularly stubborn emissions, such as heavy industry and aviation. Germany is about to import the lion’s share of its future green hydrogen needs because it does not have the space to generate additional renewable energy.
Current scenarios predict domestic demand for hydrogen and its synthetic products of around 45 to 110 terawatt hours (TWh) by 2030, rising to 400 to 700 TWh by 2045, ESYS said.
