Ohmium International, a prominent green hydrogen company, has been chosen to supply proton exchange membrane (PEM) electrolyzers for Croatia's first green hydrogen project at the INA Rijeka Refinery in Kostrena. The project, led by IVICOM in collaboration with INA and the Croatian government, aims to establish a 10MW green hydrogen plant that will utilize solar power to produce green hydrogen. This effort is a part of Croatia's strategy to achieve climate neutrality by 2050 by installing 70 MW of hydrogen production facilities by 2030 and scaling up to 2750 MW by 2050. The project is financed through the Croatian government's Recovery and Resilience Facility, highlighting the commitment to sustainable energy practices. The partnership between IVICOM and Ohmium is essential for the successful realization of this project, which underscores the significance of green hydrogen innovation for the future. Ohmium's advanced PEM electrolyzer technology will play a crucial role in decarbonizing the Rijeka Refinery and supporting Croatia's transition towards sustainable energy sources. This initiative not only contributes to decarbonization but also sets an example for green projects and innovation in Europe, showcasing the potential of green hydrogen in refinery operations and transportation sectors.
