The evolving landscape of liquefied natural gas (LNG) infrastructure in South-East Europe is increasingly influenced by regulatory frameworks aimed at decarbonisation. The Council of European Energy Regulators (CEER) has released a report that, while not specifically targeting the region, outlines significant implications for countries reliant on LNG as a critical component of their energy security and industrial competitiveness. As these nations navigate the transition to a lower-carbon economy, understanding the regulatory shifts and their impact on LNG terminals becomes essential.
South-East Europe presents unique challenges compared to the more established gas markets in north-western Europe. The region has a lower density of pipeline infrastructure, limited storage capacities, and minimal domestic gas production. Consequently, LNG terminals in adjacent EU member states play a pivotal role in ensuring gas availability and flexibility. The CEER report provides insights into how these terminals may adapt over the next decade, which is crucial for regional stakeholders.
Central to the CEER analysis is the recognition that LNG terminals are transitioning from traditional fossil fuel infrastructures to multi-molecule facilities. This shift allows them to accommodate not only natural gas but also low-carbon alternatives such as biomethane, synthetic methane, liquefied hydrogen, ammonia, and even captured carbon dioxide for export. For South-East Europe, where LNG access points are limited yet strategically positioned along EU energy corridors, this evolution is particularly pertinent.
The Croatian terminal on Krk Island and the Greek LNG system centered around Revythoussa are two key gateways in the region. The Krk terminal has expanded its regasification capacity to approximately 6 billion cubic meters (bcm) per year, facilitating supply not just to Croatia but also to Hungary and Slovenia, thereby enhancing regional energy security. This terminal is expected to implement measures aimed at reducing emissions through electrification and optimizing operations, positioning it as a potential hub for future synthetic methane imports.
For countries in South-East Europe that depend on Croatian gas flows for winter supply stability or as a buffer against pipeline disruptions, the CEER report offers reassurance that decarbonised LNG will not equate to reduced availability. Instead, it suggests that these terminals will remain vital assets for security of supply well into the 2030s, countering concerns about potential gas shortages linked to decarbonisation efforts.
Meanwhile, the Greek LNG system serves as a crucial southern gateway for gas imports into Greece and neighboring countries like Bulgaria. Notably, initiatives such as ApolloCO₂ aim to leverage Revythoussa’s capabilities for carbon dioxide logistics—enabling the collection and maritime export of captured CO₂ from various industrial sources across South-East Europe. This development could be instrumental in maintaining industrial operations amid stringent EU climate policies.
The CEER report also addresses the potential for hydrogen and its carriers within LNG infrastructure. While it stops short of designating LNG terminals as hydrogen hubs, it acknowledges the feasibility of adapting these sites for ammonia and liquefied hydrogen imports. Given Greece’s strategic location along key Mediterranean shipping routes and Balkan energy corridors, it is well-positioned to facilitate the entry of low-carbon molecules into South-East Europe from diverse global sources.
In terms of regulatory implications, the CEER emphasizes the need for national regulators in South-East Europe to avoid constraining terminal adaptations through restrictive tariff or licensing regimes. This guidance is particularly relevant in a region where regulatory frameworks often prioritize cost containment over transformative change. To enable investments in electrification and CO₂ handling at LNG terminals, predictable regulatory cost recovery mechanisms will be essential.
From a market perspective, LNG terminals play a critical role in price formation and volatility management within smaller South-East European gas markets that are susceptible to external shocks. The flexibility offered by LNG imports has already proven effective in mitigating extreme price fluctuations in recent years. The CEER’s endorsement of these terminals as long-term assets underscores their ongoing importance even as decarbonisation progresses.
While the CEER report does not prescribe a singular pathway for South-East Europe’s energy transition, it presents various technological and regulatory options that can be tailored to regional needs. For Western Balkan countries seeking deeper integration with EU markets, aligning with EU standards on emissions accounting and infrastructure interoperability will be increasingly vital.
As industrial stakeholders face pressures from EU carbon pricing mechanisms, LNG terminals evolving into multi-molecule hubs could support credible decarbonisation strategies for gas-based processes—provided lifecycle emissions can be effectively monitored and verified. This places LNG infrastructure within a broader compliance framework rather than relegating it to a transitional phase.
In conclusion, while the CEER’s report on LNG terminal decarbonisation does not serve as an explicit strategy document for South-East Europe, its findings resonate throughout the region. The limited number of LNG gateways underscores the significance of each regulatory decision impacting these assets. Decarbonisation does not diminish their strategic value; rather, it redefines it amidst emerging challenges and opportunities in cleaner energy supplies and industrial resilience.
