Various climate neutrality scenarios identify hydrogen as an important energy source for achieving climate neutrality. Depending on the scenario, the demand of the sectors and the regional distribution of these differ. The research report “Regionalization of Hydrogen Scenarios – A comparative analysis of demand, infrastructure and supply” examines the extent to which the approved hydrogen core network can cover these differences. Depending on the demand scenario, more than three quarters of regional hydrogen demand by 2045 could occur in districts that could have a good or very good connection to the hydrogen core network. However, depending on the scenario, around one-sixth of demand could arise in districts that are not connected to the hydrogen core network and would therefore be dependent on local hydrogen production.
There are currently plans to build 10 GW of electrolysis capacity in Germany by 2030. Depending on capacity utilization, these electrolysers could produce between 14 and 28 TWh of hydrogen per year. However, 85 percent of production is planned in districts that could have a very good connection to the core grid. Based on the assumptions made, only around 1 percent of the hydrogen would be produced in districts that would not have access to the core grid in the current planning. This would only cover a fraction of the scenario-based demand in these poorly connected regions.
