Every Indian kitchen knows the ritual: watching the LPG cylinder gauge, calling for a refill, and hoping the price has not moved again. Greenvize, a Faridabad clean-tech startup, has built a stove that simply steps out of that ritual altogether. Its hydrogen stove makes its own cooking fuel, on the spot, from water — no cylinder to order, no refill to chase, no queue to stand in.
The idea is beautifully direct. Inside the unit, a built-in proton exchange membrane (PEM) electrolyser splits distilled or reverse-osmosis water into hydrogen and oxygen using electricity. The hydrogen is generated on demand the moment the stove is switched on — the company says generation starts within about 30 seconds — and passes through safety and conditioning stages, including a bubbler, a buffer tank and a multi-stage flame back arrestor, before reaching a catalytic burner that produces a clean, smokeless flame. The only combustion by-product is water vapour, and the oxygen released along the way goes back into the kitchen air.
The numbers are what make it feel like a genuine kitchen appliance rather than a laboratory curiosity. The company says around 100 millilitres of water and roughly 1 kWh of electricity deliver up to six hours of continuous cooking, and the domestic models carry a 3-litre water tank. Because the fuel is made as it is used, there is no stored hydrogen in the standard configuration, and the stove works with ordinary utensils and everyday cooking — roti, sabzi and all — rather than asking the cook to change how they cook. The company says a typical induction cooktop would use roughly 9–12 kWh for the same six hours, against about 1 kWh for its system.
This is already cooking real meals in real kitchens. GreenVize SPC Techno Pvt Ltd, the company behind the stove, made its first sale in March 2026 to the Indian Army, and the company says that stove is now in use at high altitudes in Jammu. A household in Bihar’s Vaishali district bought the double-burner model and, as reported by The Indian Express, its owner calls the design simple and says he no longer worries about gas running out or getting expensive. A restaurant in Khliehtyrshi, in Meghalaya’s West Jaintia Hills, has been running Greenvize’s commercial stoves for months and says they cook quicker than the LPG stoves they replaced.
Greenvize offers the stove as a single-burner model at Rs 1,05,000 plus GST and a double-burner model at Rs 1,50,000 plus GST, with a commercial stove at Rs 3,50,000. The company, registered in January 2025, was co-founded by Sanjeev Choudhary, a mechanical engineer with an M.Tech in design engineering, who set out to build a practical hydrogen system that India would not need to import anything for. Beyond cooking, Greenvize also builds hydrogen dispensers, hydrogen fuel-cell systems, biomass power plants and pressure-swing adsorption oxygen and nitrogen generators, and its hydrogen cooktops were presented as a case study at a Bureau of Indian Standards workshop in August 2026.
What comes next is a smarter stove: the company says it aims to add Wi-Fi connectivity, app control and voice integration, and to take the stovetop to other countries, starting with the Maldives. For now, though, the achievement is already sitting on the countertop — a familiar stainless-steel stove, with two golden burners, quietly turning a glass of water and a trickle of electricity into dinner, and freeing one more Indian kitchen from the cylinder.
