Overview

Croatia’s national oil company, INA, has completed the installation of an 11 MW solar power plant at its Rijeka refinery, marking a critical first step towards the country’s first commercial green hydrogen production facility. This €15 million project, co-financed by Croatia’s National Recovery and Resilience Plan, will integrate electrolyzers by late 2026 to produce approximately 1,500 tons of green hydrogen annually, primarily targeting the transport sector for significant decarbonization impact.

In Depth

Background

In alignment with broader European Union climate objectives, Croatia is actively accelerating the decarbonization of its energy mix and transitioning towards renewable energy sources. This initiative is a crucial component of INA’s strategic efforts to reduce fossil fuel dependency and introduce sustainable fuel alternatives. The project’s significant co-financing from Croatia’s National Recovery and Resilience Plan (NRRP) underscores its instrumental role in enabling large-scale green energy projects and supporting member states’ contributions to the ambitious EU Green Deal objectives.

Key Findings

Croatia’s national energy company, INA, has successfully completed the installation of an 11 MW solar power plant at its Rijeka refinery. This landmark installation constitutes the crucial first phase for what is set to become the country’s initial commercial green hydrogen production facility. The solar plant will provide dedicated renewable electricity to the planned electrolyzer system, representing a significant milestone in INA’s overarching decarbonization strategy.

Technical Details

The 11 MW solar photovoltaic plant, now fully operational, is specifically engineered to power an adjacent electrolyzer system. This electrolyzer system is slated for installation by the end of 2026. Once fully commissioned, the facility is projected to produce approximately 1,500 tons of green hydrogen annually. A substantial portion of this output is specifically earmarked for the decarbonization of the transport sector, with a particular focus on heavy-duty and public transportation. The entire project benefits from a €15 million co-financing agreement through Croatia’s National Recovery and Resilience Plan.

Strategic Significance & Outlook

The successful completion of the solar plant at the Rijeka refinery marks a pivotal step towards establishing Croatia’s nascent green hydrogen economy. While the initial annual production capacity of 1,500 tons will address a segment of domestic transport sector demand, it also lays foundational groundwork for broader green hydrogen adoption across other industrial sectors. This project’s success is anticipated to stimulate future investments and foster further development of essential hydrogen infrastructure, positioning Croatia as a key clean energy leader within the region. Moreover, it serves as an exemplary model for similar green hydrogen integration initiatives at other refinery sites globally.
