Solar panel installation has been completed at INA’s Rijeka Refinery for its first commercial green hydrogen production facility.
This also fulfils the initial contractual obligations under the 15 million euro co-financing agreement provided through Croatia’s National Recovery and Resilience Plan (NRRP). The 11 MW solar power plant will generate renewable electricity to power the electrolyser.
Before commissioning, the plant will undergo final testing and all required technical verification procedures. Installation of the electrolyser is also ongoing, with completion expected by the end of 2026.

KONČAR is the project’s main contractor, with an investment valued at approximately 61 million euros.
The facility is expected to produce approximately 1,500 tonnes of green hydrogen annually, with the first molecules scheduled to be produced in 2027. Upon completion, the green hydrogen will be supplied to the market, primarily for use in the transport sector, while also supporting the refining processes at the Rijeka Refinery.
