How about a compact hydrogen-based cooking appliance designed for residential and commercial kitchens.
Yess! You read right as Indian clean-tech startup Greenvize has launched a compact hydrogen-based cooking appliance designed which has a system that integrates a proton exchange membrane (PEM) electrolyser directly into a cooking unit.
Greenvize Launching Hydrogen-based Cooking Appliance
Further this would enable on-site hydrogen generation from water without the need for storage or distribution infrastructure.
It appears that the Greenvize system produces hydrogen gas on demand via water electrolysis unlike conventional hydrogen supply chains that rely on pressurized cylinders or pipelines.
The generation of Hydrogen begins instantly as soon as the user turns the knob, effectively delivering fuel in real time.
It uses electrolysis, under which water molecules are split into hydrogen and oxygen.
This appliance uses Hydrogen as the cooking fuel, producing only water vapor as exhaust. So the oxygen is released into the surrounding environment–helping to improve air quality in enclosed kitchen spaces.
Moving ahead, the appliance requires around 100 ml of distilled or reverse osmosis (RO) water and approximately 1 kWh of electricity to deliver up to six hours of continuous cooking, said Sanjeev Choudhary, founder of Greenvize Energy Solutions.
Further claiming that the system can also be paired with rooftop solar, enabling off-grid cooking powered entirely by renewable energy.
So far, major energy companies continue to invest in large-scale, centralized green hydrogen production, storage, and transport infrastructure—primarily targeting industrial applications.
Helpful in hlHigh-demand Environments
On the other hand, Greenvize claims to have miniaturized hydrogen generation into a plug-and-play system for deployment in homes and commercial kitchens.
During the time when LPG is subject to price volatility and supply constraints, Greenvize is positioning its hydrogen system as an alternative to both LPG and induction cooking.
This is going to be especially helpful particularly in high-demand environments such as hotels and community kitchens.
Moving ahead, Sanjeev added, “While both induction stoves and the Greenvize hydrogen cooking system use electricity, the efficiency, flexibility, and real-world usability are fundamentally different—especially for hotels, community kitchens, and high-demand cooking environments.”
A typical induction cooktop consumes around 1.5–2 kW per burner, translating to roughly 9–12 kWh for six hours of operation, said Sanjeev.
Competitively, the Greenvize system requires about 1 kWh of electricity to generate sufficient hydrogen for six hours of cooking.
Sanjiv said, “In its standard configuration, the electrolyser is directly coupled with the cooking unit, with hydrogen generated and consumed in real time, eliminating the need for storage. However, the system can also be configured with hydrogen storage, allowing production during off-peak hours or periods of solar generation and subsequent use during peak demand.”
Adding, “For such applications, hydrogen can be stored in compressed gas cylinders (typically 200–300 bar) or in low-pressure buffer tanks for short-term balancing,” Sanjeev said. “GreenVize can customize the system based on operational needs and applications. We can also supply hydrogen storage solutions based on the client’s requirement. This includes storage cylinders/cascade systems.”
You must be wondering about the price, so here it is – its single-burner hydrogen stove is priced around INR 1,05,000 + GST and double-burner hydrogen stove INR 1,50,000 + GST.
