Open-source modeling of the future role of renewable hydrogen in Germany and Europe

In the project "Open Hydrogen Modeling", we expand and link three Berlin-based open-source models: the Global Gas Market Model (GGM), the Global Energy System Model (GENeSYS-MOD), and the electricity sector model DIETER. We investigate the prospects of the hydrogen markets in creation, ranging from the global market to the European and German market. We are particularly interested in the interaction of renewable-based hydrogen with the electricity sector and the influence of competing flexibility options such as electricity storage and sector-coupling, and in the resulting needs for additional deployment of renewable generators. We also look at the arbitrage between natural gas-based and renewable electricity-based hydrogen, in particular in the global context.
