Economical production and transport are the key challenges for green hydrogen. GENIUShy offers an integrated solution for the industry and the energy sector.

Large quantities of hydrogen must be imported to ensure a climate-neutral energy supply for German industry. Efficient transport using hydrogen carriers such as ammonia or methanol is the key.

Hydrogen has the highest mass-specific energy density and burns without CO2 emissions. There is no alternative to hydrogen for the energy transformation. The European energy system can only be decarbonised with green hydrogen, as conventional or “grey” hydrogen is produced by steam reforming from fossil fuels (usually natural gas).

Green hydrogen requires electricity from renewable energy sources such as photovoltaic, wind, biomass or hydroelectric power plants. However, these sources are only available to a very limited extent in Germany and large parts of Europe for the economic and continuous production of hydrogen. It is necessary to import hydrogen from windy and sunny regions. The direct import of hydrogen through pipelines can be realised economically for distances of up to around 5,000 km. In addition, hydrogen will be imported by sea.

The challenge in storing and transporting hydrogen is its very low volume-specific energy density. This task can be solved by using suitable hydrogen carriers with a higher energy density, such as ammonia or methanol. Ammonia is already being transported by sea in very large quantities, as it can be liquefied at a pressure of 9 bar at 20°C and is therefore very easy to handle. This makes ammonia an ideal hydrogen storage medium for long transport routes.
