EU delegated act for the requirements of electricity to producegreen hydrogen in the transport sector

▪ Current Status and Scope of the Delegated Act

• Due to RED II’s scope the delegated act so far is applicable on the transport sector

• Up coming RED III will set targets for the industry sector and therefore the delegated act may also be the bases to define criteria for green hydrogen in general

▪ Criteria for green hydrogen set by delegated act

• Green hydrogen can only be produced from renewable electricity

• Electricity needs to be produced by additional RES which has not been commissioned 12 month before commissioning of the electrolyzer

• No state aid for renewables (e.g. EEG) has been provided

• Electrolyzer and RES need to be situated in the same or neighbouring (if there are no congestions) bidding zones

• Synchronicity of Electrolyzer and RES on 15min scheme
