Research report published: Short study - Provision of hydrogen with low GHG footprint (possibilities - state of development - costs).

Hydrogen is already a key component in the energy and chemical sectors. Its importance will continue to grow in the coming years as part of the necessary reduction in greenhouse gas emissions (→ H2 strategy). The most economical and currently most widely used way to generate H2 is by reforming natural gas (gray H2).


In the current economic policy discussion, water electrolysis using electricity from renewable sources is particularly favored as a sustainable option for H2 production (green H2). However, H2 can also be produced from fossil natural gas with a greatly reduced greenhouse gas footprint. To do this, the carbon chemically bound in the raw material must be captured and permanently deposited (blue H2).
