The 2023 CEF Energy call for works and studies for cross-border renewable energy projects has led to the selection of five new Actions that aim to support the delivery of such projects. The awarded Actions involve five EU countries – Estonia, Latvia, The Netherlands, Germany, and Poland – and cover sectors like offshore and onshore wind, biomass, district heating, and green hydrogen/ammonia. Notable projects include SLOWP, which focuses on building an offshore wind park in Estonian coastal waters by 2030, and ULP-RES, aiming to establish a greenfield onshore wind farm in Estonia and Latvia. Another project, UNITED HEAT, targets deep decarbonisation of district heat production in Görlitz/Zgorzelec, with funding for technical studies and works on biomass heating and district heating infrastructure. The CICERONE-Ammonia project, part of a wider initiative, plans to create a renewable hydrogen value chain in Europe, integrating renewables from Spain. These initiatives, supported by a total of EUR 67.4 million from the CB RES window under CEF Energy, play a crucial role in promoting cross-border cooperation in renewable energy and contributing to the EU's decarbonisation strategy and energy market integration.
