In order to meet the European Green Deal and REPowerEU objectives, the CESEC region needs to step up the efforts for renewable energy deployment, including renewable and low-carbon gases. In order to do so, an adequate network of infrastructure, alongside a fit-for-purpose regulatory framework, needs to be developed. In this context, DG ENER has commissioned a study to Grant Thornton in association with AF Mercados EMI (ENER/C4/2021-444 - CESEC’s region potential for renewable and low-carbon gas deployment in the context of infrastructure development) aiming at exploring the potential for the production and deployment of renewable and low-carbon gases (renewable hydrogen and biomethane specifically), as well as their integration in the CESEC region. In accordance with the increasing importance of hydrogen and biomethane in Europe, the 2013 TEN-E Regulation (REGULATION (EU) No 347/2013) has been revised to introduce new infrastructure categories and end policy and financial support to cross-border natural gas infrastructure.
