The European Commission is in the last stages of defining the EU's low-carbon hydrogen, a pivotal move in the transition towards sustainable energy sources. The EU's renewable energy framework mandates a shift towards 'green' hydrogen, prompting the need for clear definitions. The proposed 'low-carbon' criteria center around emissions reduction, with a requirement that hydrogen emits only 30% of the fuel it replaces. Various methods, including accounting for the CO2 intensity of electricity production, are being considered. These methods aim to favor hydrogen production during renewable energy peaks, promoting cleaner energy practices. Legal certainty for producers and users is emphasized, with Jens Geier highlighting the importance of flexibility for future enhancements. The final proposal will undergo evaluation by EU countries and the European Parliament, marking a crucial step in shaping the EU's hydrogen economy.
