The European Union has officially recognized three voluntary certification systems for renewable fuels of non-biological origin (RFNBO), operated by REDcert, ISCC, and CertifHY. These certifications ensure the sustainability of green hydrogen production, allowing for auditing and the issuance of Proof of Sustainability certificates. In Germany, these systems enable national producers to qualify for financial incentives like a 3-euro bonus per kilogram of renewable hydrogen under the THG quota, supporting local production and the EU's decarbonization goals. The recognition of these certification systems aims to harmonize standards across Europe, enhancing investor and industrial confidence and accelerating infrastructure development for the energy transition. Producers anticipate that the measure will improve their competitiveness by facilitating access to funding and local incentive programs. This strategic milestone highlights the importance of hydrogen in achieving climate targets for 2030 and beyond, making renewable hydrogen more attractive in industrial and political projects across the continent.
