GreenVize is developing a residential hydrogen cooking system designed to replace LPG cylinders in Indian households. The system uses an on-site electrolyzer to split distilled water into hydrogen and oxygen, providing a zero-emission fuel source for daily cooking. The startup focuses on reducing India's reliance on imported liquefied petroleum gas by utilizing affordable catalyst materials instead of expensive platinum group metals. This approach aims to make green hydrogen commercially viable for domestic use and reduce the carbon footprint of residential heating.

The tech is simple electrolysis, but the energy math is the real question. How much electricity does this draw from the grid to produce enough hydrogen for a standard meal? If the local grid is still coal-heavy, this is just shifting emissions from the kitchen to the power plant.

Exactly. Also, distilled water is a specific requirement here. If users try to use tap water, those non-platinum electrodes will likely foul or corrode quickly. The maintenance cycle for the electrolyzer will decide if this actually works in a real kitchen.

Reducing LPG imports is a strong policy goal for India, but the safety regulations for storing hydrogen inside a residential home are a nightmare. I want to see how they handle the pressure vessel certifications before this hits the mass market.

Basically a home-scale hydrogen plant to stop buying LPG. Interesting move to ditch the platinum catalysts to lower the cost. It is a bold play, but the efficiency of the electrolysis process is the missing detail here.
