Project Description
The project involves the construction of a 2 MW photovoltaic (PV) plant coupled with a 430-kW proton exchange membrane (PEM) electrolyser. This system will facilitate the daily production of approximately 200 kg of hydrogen. The plant uses thermal conversion (gasification) to turn organic material, such as non-recyclable plastics, sludge, and textiles, into hydrogen and carbon black. It consists of three main systems: thermal conversion, cleaning and cooling, and hydrogen preparation. The plant is also capable of processing wastewater sludge. The estimated yearly production of hydrogen is 80 tonnes. Additionally, the project plans to install 200 kW fuel cells along with hydrogen storage. The electricity produced from the 2 MW PV system will be used to power the PEM electrolyser. The stored hydrogen will also be used in fuel cells for electricity production when necessary, creating a small microgrid within an industrial area in Zagreb, Croatia.
Key Metrics
Technology: Gasification, PV system, PEM electrolyser, and fuel cells.
Hydrogen Production: 200 kg per day, 80 tonnes per year.
Plant Capacity: 2 MW PV system, 430 kW PEM electrolyser, and 200 kW fuel cells.
Impact and Benefits
The testbed project will create a sustainable energy source for the industrial area, reducing reliance on conventional energy grids. The gasification plant tackles the problem of non-recyclable organic waste while providing clean hydrogen for energy use. The stored hydrogen can be used for fuel cell electricity generation, enabling greater energy autonomy in the local industry.
Current Status
The plant’s construction is underway, with the PV and PEM systems being installed. No specific challenges have been reported at this stage. Future milestones include commissioning the PEM electrolyser and completing hydrogen storage installation.
Progress Highlights
The project has demonstrated how waste2energy plants can help industries transition toward self-sufficiency while managing organic waste sustainably. Early successes show that the model could be replicated in other industrial settings across Europe, enhancing local energy resilience.
Future Plans
Upcoming steps include completing the hydrogen storage system, integrating the 200 kW fuel cells, and operationalizing the microgrid. The project aims to contribute to the region’s broader hydrogen economy, with potential expansions based on the plant’s performance.
