GreenHub is a CO2-free electricity generator that uses hydrogen fuel cells. The system provides clean energy independently of the power grid, utilizing an electrochemical cell with a polymer electrolyte, and is equipped with a safety system powered by SafetyBoard technology. The system’s only byproduct is pure demineralized water. The device is designed exclusively for indoor use or in protected outdoor areas.
