Sustainably or renewably produced hydrogen is often referred to as green. However, the fact is that hydrogen is always colourless.

Nevertheless, the European Commission, the German government and other institutions have attempted to legally define criteria for climate-friendly and sustainable hydrogen production. As is so often the case in an environmental context, the term ‘green’ is used symbolically. But what does green hydrogen actually mean?

In the legal text, the term ‘green’ only appears in the EEG and the GEG. In the EEG – the law regulating the production and use of renewable energies – it refers exclusively to hydrogen produced by electrolysis using renewable electricity. In the GEG, on the other hand, the term refers to passages in RED II that also define sustainability criteria for biomass.

The recognition and transparent classification of our reformer technology for producing hydrogen from biogas is of particular interest. Our sister company BtX energy GmbH has therefore compiled some key facts to clarify the central question: Green hydrogen from biogas
