The European Union has introduced the Fourth Gas Package, comprised of Regulation 2024/1789 and Directive 2024/1788, to revamp the gas regulatory framework. These regulations, effective from August 4, 2024, focus on promoting renewable gas, natural gas, and hydrogen markets while upholding key principles like third-party access and consumer protection. Emphasizing the reduction of greenhouse gas emissions and bolstering security of energy supply, the legislation aims to drive the transition to climate neutrality by fostering a robust hydrogen market. The new framework includes provisions for renewable gas, low-carbon hydrogen, and synthetic gaseous fuel, all with stringent emission reduction thresholds. Notably, hydrogen's quality standards will be defined through a technical standardization process to ensure market efficiency. Tariff incentives, firm capacity requirements, and access regulations for renewable and low-carbon gases are central to the package. System operators are entrusted with facilitating the connection of production facilities and ensuring transparent access procedures. Member States are mandated to enable access to renewable and low-carbon gases, emphasizing a shift towards sustainable energy sources. While some climate-related derogations allow for refusal of network access under specific conditions, the overall focus remains on promoting cleaner energy and driving decarbonization efforts across the EU.
