Indian Startup Greenvize Launches Compact PEM Electrolyser-Integrated Hydrogen Cooking System

Indian clean-tech startup Greenvize has launched a compact hydrogen-based cooking system designed for residential and commercial kitchens. The appliance integrates a proton exchange membrane (PEM) electrolyser directly into the cooking unit, enabling on-site hydrogen generation from water without requiring storage or distribution infrastructure.

The system generates hydrogen on-demand through electrolysis when activated, splitting water molecules into hydrogen and oxygen. The hydrogen serves as cooking fuel while producing only water vapor as exhaust, with oxygen released into the kitchen environment.

According to founder Sanjeev Choudhary, the system requires approximately 100 ml of distilled or reverse osmosis water and 1 kWh of electricity to deliver six hours of continuous cooking. The unit can be paired with rooftop solar panels for off-grid operation powered entirely by renewable energy.

Greenvize positions the hydrogen cooking system as an alternative to liquefied petroleum gas (LPG) and induction cooking, particularly for hotels and community kitchens. The company claims efficiency advantages over induction cooktops, which consume 9-12 kWh for six hours of operation compared to the hydrogen system's 1 kWh requirement.

The system operates with standard cooking utensils and traditional cooking techniques, addressing limitations of induction cooktops that require compatible magnetic cookware. Single-burner units are priced at INR 1,05,000 ($1,128) plus GST, while double-burner units cost INR 1,50,000 plus GST.

The system can also be configured with hydrogen storage in compressed gas cylinders or low-pressure buffer tanks for off-peak production scenarios.
