New Kitchen Stove Uses Water to Cook Food Instead of Natural Gas

Greenvize has introduced a compact hydrogen cooking stove designed for homes and commercial kitchens, capable of generating its own fuel from water.

The system integrates a proton exchange membrane (PEM) electrolyzer directly into a standard cooking unit, allowing users to produce hydrogen on demand.

On-Demand Hydrogen Generation

The stove splits water into hydrogen and oxygen through electrolysis. The hydrogen is immediately used as a cooking fuel, while water vapor is released as the only exhaust.

The unit also releases oxygen during operation, which the company says can improve air quality in the surrounding environment. Notably, the system does not require external storage or fuel distribution infrastructure in its standard configuration.

Power and Water Requirements

According to Greenvize director and co-founder Sanjeev Choudhary, the system requires about 100 milliliters of distilled or reverse osmosis water and approximately one kilowatt-hour (kWh) of electricity to begin hydrogen production.

This input can support up to six hours of continuous cooking. The unit can also be paired with rooftop solar panels, making it suitable for areas with unstable electricity supply or limited access to gas networks.

Optional Storage and Customization

While the base system generates and consumes hydrogen in real time, Greenvize offers optional storage configurations. These allow hydrogen to be produced during off-peak hours or periods of solar generation and used later during high-demand periods.

Storage options include compressed gas cylinders operating at 200 to 300 bar, as well as low-pressure buffer tanks for short-term use. The company said it can customize storage solutions based on specific client requirements.

Energy Efficiency and Use Cases

Choudhary said the system offers a different approach to energy use compared to traditional induction cooktops, which can consume up to two kilowatts per burner and around 12 kWh over six hours.

In contrast, the hydrogen system converts electricity into fuel that is burned directly. The unit features stainless-steel construction and integrated safety systems, supporting continuous use in demanding environments.

Greenvize is targeting high-demand settings such as hotels, community kitchens, and rural areas, where reliability and flexibility are essential.

Pricing and Availability

The single-burner version of the hydrogen stove is priced at $1,128 plus GST, while the double-burner model costs around $1,610 plus GST.

The company said the product aligns with India’s National Green Hydrogen Mission, which aims to support a transition toward more sustainable energy systems.
