Croatia is transforming its energy sector by diversifying away from fossil fuels, leveraging significant renewable potential (hydro, wind, solar), and strengthening energy security through LNG infrastructure. The country targets 42.5% renewable energy in gross final consumption by 2030, supported by new investments in solar, geothermal, and plans for a 30% nuclear share by 2040.

Efforts are focused on modernizing the power grid, enhancing energy efficiency in buildings (40-80% funding rates), and developing hydrogen-ready pipelines to connect with neighbors like Slovenia and Hungary.

Croatia is rapidly advancing a hydrogen economy by 2050. The Hydrogen Strategy of the Republic of Croatia until 2050 outlines a clear path for using renewable and low-carbon hydrogen, aiming for 32+ pilot projects to establish a sustainable, integrated hydrogen ecosystem.

The national oil company, INA, is developing a 10 MW electrolyzer with a 10+ MW solar plant in Rijeka to produce 4,000 kg of green hydrogen daily, supported by a network of 10+ filling stations.

Croatia, along with Slovenia and Italy (Friuli Venezia Giulia), is part of the North Adriatic Hydrogen Valley project, aiming for regional cooperation on hydrogen production and use.
