In 2024, the energy landscape in the Central and Eastern European (CEE) region witnessed notable transformations driven by advancements in nuclear energy and liquefied natural gas (LNG) infrastructure. Nuclear energy, particularly the adoption of Small Modular Reactors (SMRs), took center stage in countries like the Czech Republic, Bulgaria, Poland, Romania, and Serbia. These nations made substantial progress in nuclear projects, signaling a resurgence of nuclear power in the region. Simultaneously, LNG infrastructure expansion played a critical role in enhancing energy security across the CEE region. Major milestones included the commissioning of the Alexandroupolis LNG Terminal in Greece and advancements in LNG infrastructure in Poland and Hungary. These developments aimed to secure long-term LNG supplies and diversify energy sources in the region. Poland emerged as a leader in the oil and gas sector, with significant achievements in exploration activities and gas pipeline projects. The country solidified its position by securing new licenses, confirming substantial reserves, and advancing key infrastructure projects with neighboring countries. Furthermore, the European Commission's initiative to establish a European Industrial Alliance for SMRs showcased a collective effort to accelerate the deployment of small modular reactors across Europe by the early 2030s. This initiative reflects a broader support for nuclear energy and signifies a shift towards sustainable and diversified energy sources in the CEE region.
