Major Investment in Energy Infrastructure
On March 10, 2026, Croatia inaugurated its upgraded heavy residue processing plant at the Rijeka Oil Refinery, marking a significant milestone in the country's energy sector. This project, valued at approximately 700 million euros, is considered one of the largest industrial investments in Croatia's recent history. The upgrade includes the installation of a Delayed Coking Unit (DCU), which enhances the refinery's ability to process heavier crude oil and increases the production of high-value fuels such as diesel and gasoline.
Details of the Upgrade
The Rijeka Refinery, owned by the Croatian oil company INA, which is partially controlled by the Hungarian oil group MOL, can now process up to four million tons of crude oil annually. This upgrade is expected to boost diesel production by around 30%, significantly reducing the need for imported vacuum gas oil, primarily sourced from Russia. The construction involved over 10,000 tons of steel and 60,000 cubic meters of concrete, illustrating the scale of the project.
Broader Implications for Energy Security
The completion of the refinery upgrade comes at a time of geopolitical instability, particularly due to ongoing conflicts in Iran that have impacted global oil supply chains. Croatian Minister of Economy Ante Šušnjar emphasized the importance of this project for national energy security, stating, “Strong and reliable infrastructure means greater security, more stable supply and a more resilient economy.” He noted that the modernization process had been lengthy, with multiple ministers overseeing its development since its inception.
Future Developments
In addition to the refinery upgrade, INA is investing in a green hydrogen plant at the site, supported by a 15-million-euro grant under the National Recovery and Resilience Plan. This facility, expected to be operational by the end of 2026, will include a 10-megawatt electrolyser and an 11-megawatt solar plant, contributing to Croatia's transition towards a lower-carbon economy.
Regional Perspectives
Levente Magyar, Deputy Minister of Foreign Affairs and Trade of Hungary, highlighted the regional significance of the project, stating, “This is a great day for the energy security of our region because we deeply believe that energy security in this region is indivisible.” His remarks reflect a shared commitment to enhancing energy sovereignty and security among neighboring countries.
Official Statements & Responses
Minister Ante Šušnjar remarked on the project's role in reinforcing Croatia's energy infrastructure, asserting that it would benefit not only the Croatian economy but also its regional partners. Zsuzsanna Ortutay, President of the Management Board of INA, reiterated the importance of the upgrade for maintaining competitiveness in the energy market.
Criticism & Opposition
While the upgrade has been largely celebrated, some critics have pointed to the slow pace of modernization and the reliance on foreign investment as potential vulnerabilities in Croatia's energy strategy. However, the overall sentiment among officials remains positive, focusing on the benefits of enhanced energy security and economic resilience.
What's Next
As the Rijeka Refinery begins operations at full capacity, stakeholders will monitor its impact on Croatia's energy landscape and its role in regional energy security amidst ongoing geopolitical challenges.
