H2 Ludbreg

Located in northern Croatia, our Ludbreg project is currently under development and stands as one of the first green hydrogen production initiatives in the country. It aims to establish a scalable model for industrial decarbonization using locally available renewable energy.

The planned facility includes a 5 MW PEM electrolyzer, powered entirely by certified green electricity delivered through long-term power purchase agreements. A 30 MWh battery energy storage system (BESS) will support price optimization and ensure stable energy supply to the electrolyzer through energy arbitrage.

In addition to clean hydrogen production, the project is being designed with a holistic approach to energy efficiency. We are actively exploring ways to utilize all by-product energy streams, including waste heat, in alignment with circular energy principles and local sustainability opportunities.

The Ludbreg project reflects Solarwatt’s commitment to accelerating the green transition in Croatia by developing flexible, future-ready hydrogen infrastructure.
