In connection with the energy transition, green hydrogen will play a central role as a storage and carrier medium. However, only if hydrogen is obtained from renewable energies. TÜV SÜD provides the corresponding proof with the updated GreenHydrogen certification.
Worldwide, more than 600 billion cubic meters of hydrogen are produced, which are mainly intended for the chemical industry. In the future, hydrogen will also be used to store renewable energies and in the transport sector. “Green hydrogen plays a crucial role in connection with the energy transition,” says Klaus Nürnberger, Head of Energy Certification at TÜV SÜD Industrie Service GmbH. “This applies especially to the area of the much-cited traffic turnaround, where hydrogen and fuel cell technology complements battery-assisted electromobility.”

With the GreenHydrogen certification (TÜV SÜD Standard CMS 70, Version 01/2020 “Generation of Green Hydrogen”), TÜV SÜD provides evidence that regeneratively produced hydrogen has significantly lower greenhouse gas emissions than conventionally produced hydrogen or as fossil fuels. A prerequisite for the award of the Green Hydrogen certificate is that green hydrogen has a greenhouse gas reduction potential of at least 60 percent compared to the fossil comparison value. If green hydrogen is generated by electrolysis, the GHG reduction potential must be as high as 75 percent. The comparison is based on the current values of the Renewable Energy Directive II (RED II) and the values for conventional hydrogen produced using natural gas reforming. In addition, Qualities that go beyond the legal requirements, for example with regard to the use of electricity from renewable energies or the use of biomethane. Another component of the GreenHydrogen certification is a robust monitoring system of the certificate holders to guarantee the certified quality and delivery quantities.
The certified amounts of GreenHydrogen can be registered in the certificate of origin system for hydrogen from renewable energies supported by the European Union – CertifHy. According to Klaus Nürnberger, the H2-HKN system simplifies the transferability of green hydrogen in the European Union from the producer to the user.
