The EU's legislative hydrogen and gas decarbonisation package, effective from August 4, 2024, includes the Regulation on the internal markets for renewable gas, natural gas, and hydrogen (H2 Regulation) and the Directive on common rules for these markets (H2 Directive). The package updates gas market regulations to fit the EU's energy mix objectives for 2050, with a focus on renewable and low-carbon gases. Hydrogen is highlighted as vital for decarbonising heavy transport sectors and energy-intensive industries where electrification is challenging. While renewable hydrogen remains limited, the H2 Directive stresses the role of low-carbon hydrogen in meeting climate goals. Key aspects include incentivising renewable gas usage, restricting new natural gas contracts post-2049, and defining low-carbon gas criteria. The package also outlines a dedicated regulatory framework for hydrogen infrastructure development, ensuring fair access and operational guidelines. These measures aim to steer the gas industry towards a greener future in alignment with the EU's climate targets.
