Hydrogen is an important building block for achieving climate neutrality. The sooner climate neutrality is to be achieved, the sooner hydrogen has to be utilized. Thus, the role of hydrogen in the future energy system needs to be determined with high priority.
This is reflected in the growing number of national and regional hydrogen strategies. In Germany, a national hydrogen council was launched in mid-2020. In addition, a large number of publications have appeared on the fascinating element hydrogen and its future potential as an energy carrier and feedstock.
How can Germany become climate neutral by 2045 with the help of hydrogen?
This question is answered by our energy team together with the project partners from the Öko-Institut and the Wuppertal Institut in the study "Climate Neutral Germany". In the climate-neutral scenario, considerable amounts of greenhouse gas-neutral hydrogen are used, as the following figure shows.
The project team, consisting of engineers and economists, comes to the conclusion that a hydrogen demand of 63 terawatt hours (calorific value) could already emerge by 2030. By comparison, today's demand for natural gas is about 860 terawatt hours.
By 2045, domestic hydrogen demand will rise to 265 terawatt hours. This corresponds to less than one third of today's natural gas consumption in Germany.
Possible areas of application for hydrogen
- For electricity and district heating generation and power backup in the electricity sector
- As a reducing agent in the steel industry for the production of decarbonised steel
- In the chemistry sector as a molecular building block and
- For use as fuel in the transport sector (e.g. heavy-duty vehicles, aviation, ships).
