Analysis and Dialogue on GHG accounting methodologies

Interest in the topic of green hydrogen and power-to-x remains high internationally due to its relevance for the decarbonisation of hard-to-abate sectors. To ensure that switching to renewable fuels contributes to meeting the climate goals, there is a need for a set of robust standards and procedures governing their production. Renewable Energy Directive (RED II) and the two supplementing delegated acts published in early 2023 lay out the requirements for renewable hydrogen and its downstream products in the EU. With the expectation that these rules will apply for the imported hydrogen and its downstream products as well, they have international applications. In 2023, the PtX Hub organised a series of workshops for its international partners to present and discuss the relevant developments, and commissioned the consortium consisting of adelphi, Ecologic Institute and Öko-Institut to support it. 

To this end, the consortium provided expertise in the fields of hydrogen policy and greenhouse gas calculations. Different methodologies for greenhouse gas accounting for hydrogen and its downstream products have been analysed, as well as standards, certificates and other policy tools. Briefings and presentations for the international audience ahave been prepared on behalf of the PtX Hub, and nine digital dialogues with key international partners have been carried out. adelphi focused on the delegated act supplementing the Article 28 of the Renewable Energy Directive.
