New Delhi | April 11, 2026 In a bold disruption to India’s traditional cooking fuel market, a homegrown startup, Greenwise, has unveiled a futuristic cooking stove that runs on nothing but water and electricity. At a time when LPG prices continue to pinch household budgets, this innovation could signal the beginning of the end for conventional gas cylinders.
The technology behind the stove is based on Electrolysis — a process that splits water (H₂O) into hydrogen and oxygen. The hydrogen produced is then used as a clean-burning fuel for cooking, eliminating the need for LPG or PNG connections altogether. What makes this breakthrough even more striking is its zero-emission nature — no smoke, no carbon, just clean energy.
According to the company, just 100 ml of distilled water combined with 1 unit (1 kWh) of electricity can power the stove for up to six hours of continuous cooking. This claim, if proven scalable, could drastically cut kitchen fuel costs while also reducing India’s dependence on imported fossil fuels.
Beyond cost savings, the environmental impact is equally significant. Unlike traditional fuels like LPG and PNG, the hydrogen flame emits no harmful gases. Instead, the process releases oxygen back into the air, potentially improving indoor air quality — a major concern in Indian households.
However, questions remain about large-scale adoption, infrastructure readiness, and long-term safety standards. Experts say while hydrogen fuel is highly efficient, it requires strict handling protocols. Still, the innovation has already sparked intense interest across the energy and consumer markets.
If Greenwise delivers on its promises, this “water stove” could redefine cooking in India — offering a cleaner, cheaper, and more sustainable alternative. For millions struggling with rising fuel costs, this might not just be innovation — it could be a lifeline.
