The operating grants mainly concern grants towards the construction of our hydrogen transmission network (same as in 2024). An amount of € 22.3 million (2024: € 17.7 million) concerns a DAEB grant from the Dutch State to cover start-up losses in the development of the national hydrogen network. A total amount of € 17.1 million (2024: € 0) relates to a contribution from the German amortisation fund to cover costs during the development phase of the German hydrogen network. The amortisation fund imposes a conditional obligation on us that we have explained in note 28 ‘Off-balance sheet assets and obligations’.
