The ERDF and the CEF also provide full or large grant subsidies to the “new trio” sectors. The ERDF primarily finances structural adjustments and transformations in disadvantaged regions to reduce the development gap with other EU areas. From 2021 to 2027, it focuses on promoting a green and low-emission transition,[6] allocating EUR 104.3 billion to subsidize projects such as energy transition and sustainable urban mobility.[7] The CEF mainly supports the development of high-performance, sustainable, and interconnected trans-European networks across transport, energy, and digital service sectors.[8] From 2021 to 2022, the fund awarded EUR 1.66 billion in grants to 18 energy projects, including 5 electricity projects, 4 carbon dioxide projects, 3 natural gas projects, 1 smart grid project, and 5 cross-border renewable energy projects.[9]
