The demonstration unit, dubbed “DOM H2”, was developed by an interdisciplinary AGH team led by Professor Magdalena Dudek in partnership with energy group ZEPAK and engineering firm PAK Serwis.

Electricity is produced by a 6.4 kW photovoltaic array mounted on the roof of a modified shipping container. Surplus power charges lithium batteries and runs an electrolyzer that splits water to generate hydrogen, which is stored in tanks.
During sun-poor winter months, the hydrogen feeds a fuel cell that supplies both electricity and heat to household appliances such as refrigerators, washing machines and lighting, the researchers said.
AGH built a laboratory to test the integrated PV-battery-electrolyzer-fuel-cell system using standard domestic loads.
The consortium says the concept could be adapted for mobile hotels, emergency power for mass events, or rapid-deployment units for disaster-response teams.
The prototype was shown publicly this month at the Net Zero Energy & H2POLAND 2025 fair in Poznań, one of central Europe’s main hydrogen-technology exhibitions.
