Hydrogen cooking stove runs for hours using only 100 ml water and 1 kWh power

Greenvize, a clean‑tech startup, unveiled a compact plug‑and‑play hydrogen cooking stove for homes and commercial kitchens.

A built‑in PEM electrolyzer inside the unit splits water into hydrogen and oxygen on demand when a knob is turned.

About 100 milliliters of distilled or RO water and roughly 1 kWh of electricity are required to start production.

That input can support up to six hours of continuous cooking; exhaust is water vapor and oxygen is released nearby.

In standard setup hydrogen is generated and consumed in real time with no storage; optional storage (200–300 bar cylinders or low‑pressure tanks) and rooftop solar pairing are available.
