Solar power works finished under NRRP-linked grant
Croatian oil company INA has completed the installation of solar panels at its Rijeka refinery, a milestone in the development of Croatia’s first commercial-scale green hydrogen facility. The company said construction and installation activities for the 11 MW solar power plant were finalized at the end of June. The works were carried out in line with initial requirements under a €15 million grant agreement financed through Croatia’s National Recovery and Resilience Plan.
Renewable electricity to feed electrolyser for hydrogen output
The solar plant is set to provide renewable electricity to an electrolyser producing green hydrogen, forming the core of the new production system. When fully operational, the facility is expected to generate around 1,500 tons of hydrogen annually. The produced hydrogen is planned for both market supply and internal use in refinery processes.
Commissioning phase underway; electrolyser installation continues
Mechanical installation of the solar system has been completed, and the project is now moving into its final commissioning phase. This phase includes technical testing and system validation before full operation begins. Installation of the electrolyser is continuing in parallel, with completion planned by the end of 2026.
Končar delivers project with total investment near €61 million
The project is being delivered by Croatian engineering company Končar, acting as main contractor. Total investment is approximately €61 million. INA CEO Zsuzsanna Ortutay described the initiative as one of the company’s flagship sustainability projects.
Stated aims for emissions, refinery efficiency and hydrogen economy
Ortutay said the green hydrogen facility will contribute to reducing greenhouse gas emissions, improving refinery efficiency, and supporting development of Croatia’s emerging hydrogen economy.
