On 5 December 2025, the consortium comprising KONČAR Inc. and Siemens Energy Ltd. signed a contract with the client INA d.d. for the implementation of the project titled Design of the detailed execution project, procurement, delivery and installation of equipment and materials, construction works, and commissioning of the hydrogen production, distribution and storage facility on a turnkey basis for the Hydrogen Project. The total value of the contracted works amounts to EUR 22,5 million.

The project encompasses the construction of a facility equipped with electrolyzers, integrated control and monitoring systems, and the full suite of supporting infrastructure necessary to ensure safe and reliable operation. It also includes the installation of comprehensive safety, grounding, communication, fire protection, and explosion-proof systems, in strict compliance with safety standards governing hydrogen technologies.

As the first green hydrogen production facility in Croatia, this project marks a major step forward for KONČAR Group and its strategic focus on sustainable energy. Through this initiative, KONČAR affirms its role in advancing innovative, low-emission technologies, boosting energy efficiency, and supporting the decarbonisation of the industrial sector.

Green hydrogen is intended for use in transportation

The green hydrogen that would be produced is intended for the market, primarily for transportation purposes, and it could also be used in the refinery’s production process. The company recalled that, by a decision of the Ministry of Economy, it received a EUR 15 million grant from the National Recovery and Resilience Plan.

The program is for the production and distribution of hydrogen in transportation.

The hydrogen market in Croatia is in an early development phase. INA’s plant could produce about 1,500 tons of green hydrogen annually.

Of note, Croatia adopted a hydrogen strategy in 2022. The government subsidizes the installation of chargers for hydrogen fueled vehicles.
