The European Union is in the final stages of developing its Delegated Act on Low Carbon Fuels as a crucial element of its hydrogen policy, with the potential to significantly advance the EU's decarbonisation agenda. This act is essential in establishing the foundation for Europe's hydrogen industry and determining how effectively the EU can achieve its climate goals. The act aims to define a methodology for calculating greenhouse gas emissions related to low-carbon hydrogen production, with a focus on achieving a substantial reduction of at least 70% compared to fossil fuels. The article emphasizes the importance of considering all climate warming emissions, including carbon dioxide, methane, and hydrogen, and incorporating them into calculations from the beginning to prevent potential challenges in the future. There is a call for the use of the latest science and data, comprehensive climate accounting methods, and robust monitoring and verification to ensure the credibility of the act. The discussion also highlights the significance of accurately factoring in the warming potential of methane and hydrogen emissions over different timescales and leveraging new technologies like MethaneSAT and advanced sensors for precise data collection. Additionally, the article stresses the need for a realistic approach to Carbon Capture and Storage credits in the act, especially concerning blue hydrogen production. The emphasis is on being forward-thinking in policymaking to address challenges effectively and align with EU climate commitments.
