What does the Hydrogen cooker change?
Unlike traditional LPG cooking stoves, which use fossil fuels, this cooker uses a typical plug-and-play type of setup; however, it has a catalytic burner burning hydrogen instead of propane.
The hydrogen stove burner has been designed to have a high heat-producing capability with its tabletop unit comprised entirely of stainless steel; the design incorporates a double burner system design for efficient heat distribution. Although it also has a pendal like a normal gas stove, the way it functions internally has completely altered our energy consumption model.
How it works
The foundation element of the hydrogen cooking technology is the generation of hydrogen using electrolysis of water.
Burning of hydrogen using a catalytic burner: The cooking stove has an adjustable gas flow through a regulated flow pattern, which will give consistent, near-zero gas consumption.
Zero ground emissions: Most importantly, there is zero carbon dioxide (CO₂), zero carbon monoxide (CO), and zero visible smoking emissions when cooking with hydrogen.
The low-noise operation engineered for indoor use
Designed specifically for indoor applications, this appliance has been engineered to run silently and without vibration typically associated with industrial fuels.
Beyond the home: Greater & strategic applications
While technologies developed for home use can easily be scaled up to support larger-scale applications, the rollout is targeting larger sectors of clean-energy pilot projects. Below are just some applications currently under research:
Community kitchens & canteens: High-volume cooking with no carbon emissions.
Defense & remote locations: Fuel sovereignty in locations with limited access to liquefied petroleum gas (LPG).
Research institutions: Testing hydrogen as a standard source of energy.
Safety first: Engineered for hydrogen stability
Due to the volatility of hydrogen, the manufacturers of this product have instituted a multi-tier safety architecture. The appliance is also outfitted with:
Flame arrestors: To minimise the the risk of backfire and maintain the stability of flames.
Automated pressure control systems: To ensure consistent delivery of fuel.
Hydrogen-compatible valve components: Designed to reduce the risk of leaks.
The cost of innovation: The price of adoption
With a current retail price of 150,000 INR (approximately $3,650), this appliance is currently being marketed as a premium product for organisations and government pilot programs rather than households.
While it is unlikely that this stove will replace the traditional LPG cylinder in every Indian household overnight, the advent of such technology represents a significant milestone for the National Green Hydrogen Mission. Adoption will depend on the long-term sustainability of hydrogen.
The introduction of hydrogen cooking stoves in India marks a major shift from traditional LPG (Liquefied Petroleum Gas) to a system that literally uses water as fuel.
In March and April 2026, Indian clean-tech startups like Greenvize and Last Mile Energy (with their 'AquaFlame' model) launched the first commercial units designed for this purpose.
How It Works: Water to Flame
Water Source: You pour a small amount of water (about 100ml for several hours of cooking) into a specialized tank.
Electrolysis: Using electricity (from a wall socket or rooftop solar), the stove runs a PEM (Proton Exchange Membrane) electrolyzer that splits water (
$H_2O$) into hydrogen and oxygen. On-Demand Fuel: Hydrogen is generated in real-time as you turn the knob.
There is no storage of gas, which significantly reduces the risk of explosions compared to LPG cylinders. Clean Combustion: The hydrogen burns at the nozzle, producing heat and only water vapor as a byproduct—no carbon monoxide or
$CO_2$. 
Hydrogen Stove vs. LPG Cylinder
| Feature | Traditional LPG | Hydrogen Stove (AquaFlame/Greenvize) |
| Fuel Source | Fossil Fuel (Refinery byproduct) | Water + Electricity |
| Supply Chain | Delivery/Refilling required | On-site generation (Self-reliant) |
| Emissions | $CO_2$, particulate matter | Pure water vapor |
| Safety | High-pressure gas storage | No storage; hydrogen used as it's made |
| Cookware | Standard utensils | Standard utensils (No special magnetic pots needed) |
The Challenges
Upfront Cost: Currently, these stoves are priced between ₹1,05,000 and ₹1,50,000, making them much more expensive than a standard ₹3,000 gas stove.
Target Audience: For now, they are primarily aimed at commercial kitchens (hotels/canteens), research labs, and remote defense outposts where transporting LPG cylinders is difficult or expensive.
Electricity Dependence: While it saves on gas costs, it requires a steady electrical connection (though pairing it with solar panels can make it "grid-free").
Perspective: This technology aligns with India's National Green Hydrogen Mission, aiming to reduce the country’s heavy reliance on imported LPG.
While it isn't a "household standard" yet due to the high initial price, it represents a massive leap toward energy independence for Indian kitchens.
