Haryana startup’s stove makes its own hydrogen from water to cook with

GreenVize says its plug-and-play unit needs about 100 ml of water and 1 kWh of electricity for six hours of cooking, though it costs up to ₹1,50,000.

A Haryana-based clean-tech startup has launched a cooking stove that makes its own hydrogen from water. GreenVize describes it as a compact hydrogen-based system for residential and commercial kitchens. The unit is at an early stage. It speaks to India’s search for cooking fuels that do not depend on LPG cylinders.

How the stove works

The stove has a proton exchange membrane (PEM) electrolyser built into it. This produces hydrogen from water on site, so no storage or distribution network is needed. Hydrogen generation starts as soon as the stove is switched on, so fuel is supplied in real time. The only product of combustion is water vapour.

The key figures come from the company. Founder Sanjeev Choudhary says the system needs about 100 ml of purified water and roughly 1 kWh of electricity for six hours of continuous operation. One kilowatt-hour is what a 1,000-watt appliance uses in an hour.

The company has also explained the physics. According to its explanation, 100 ml of water holds about 0.36 kWh of theoretical energy and yields about 0.22 kWh of usable heat. It reaches four to six hours of practical cooking because cooking is intermittent, with an average load of 40–70 W, and because it uses catalytic combustion. In other words, the six-hour figure assumes ordinary household cooking patterns rather than a burner running flat out.

The comparison with induction is the company’s own framing. One induction burner draws about 1.5–2 kW, which adds up to 9–12 kWh over six hours. I found no independent testing of these figures.

Price and who it is for

A single-burner unit costs ₹1,05,000 and a double-burner unit ₹1,50,000. That is far above the cost of an ordinary gas stove. The company pitches it mainly at high-footfall venues such as hotels and restaurants. It is also being explored for large-scale cooking. GreenVize was founded in 2024.

The company says the stove can work without a grid connection. It can be integrated with solar panels. Choudhary has said it can also be configured with hydrogen storage, so that hydrogen is produced during off-peak hours or when solar power is available and used later.

What this means for India

The stove arrives as India explores hydrogen for everyday uses. In 2024, NTPC’s research arm demonstrated hydrogen cooking at Greater Noida with a purpose-built burner. It noted that hydrogen’s flame is almost invisible and that hydrogen cannot be premixed with air. In December 2025, IIT (ISM) Dhanbad and Indian Oil signed a ₹76.42-lakh agreement for a solar hydrogen cooking system for rural communities. At current prices GreenVize’s unit suits commercial kitchens, not most homes.

What to watch

Independent efficiency tests and safety certification will matter before any wider rollout. Running costs will depend on local electricity tariffs and on how often users must buy purified water. The price also needs to fall well below ₹1 lakh before households can consider it. For now the stove shows that on-site hydrogen cooking can be packaged into a single appliance made in India.
