CertifHy guarantees green hydrogen
CertifHy was presented at the end of October; it is a plan for an EU-wide certification system for green hydrogen that can count on broad support.
The use of hydrogen gas in industry or for transport, for example, can contribute to the greening of energy management, certainly when it is produced sustainably. That is why CertifHy was presented at the end of October; it is a plan for an EU-wide certification system for green hydrogen that can count on broad support.
"The demand for hydrogen is growing in industry. And as soon as driving on hydrogen becomes attractive, the demand will rise even further." This statement comes from Marc Londo, senior researcher at the Policy Studies Unit of ECN. "The use of hydrogen contributes primarily to the greening of energy management if it is sustainably produced. This is the aim when using energy generated from wind, biomass or biogas to produce hydrogen. But how does the buyer of the hydrogen know whether the gas is produced sustainably? There is not a good certification system yet."
ECN set up the CertifHy project in a consortium with Hinicio, TÜV SÜD and Ludwig Bölkow Systemtechnik, working with dozens of European industrial partners. A definition of sustainable hydrogen was formulated first, then a structure designed for the organisation of the certification, and finally a roadmap prepared for its realisation. At the end of October the first EU-wide 'Guarantee of Origin' (GO) system for hydrogen was presented.
Just like with green electricity, the challenge is how to show the buyer how green the supplied hydrogen is. "Guarantees of Origin are important to prove to consumers and companies how green their hydrogen is," explained Londo. "That way, they can advertise their product as 'green', for example. Guarantees of Origin can thus contribute to the energy transition, but the certification needs to be properly arranged. ECN is happy to help out with that."
"To set up the organisation, we drew on lessons from the past, for example the GO systems for green electricity," said Londo. ECN also led the preparation of the roadmap. Next year the certification system will be set up and pilots will have to be conducted to test the method in practice, confirmed Londo. "The practical tests will probably uncover the necessary technical issues. I expect that ECN will play a role in resolving them."
