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
