ALT A STOVE THAT STARTS WITH WATER? THIS ISN’T SCIENCE FICTION. Imagine filling your stove with water instead of natural gas—then turning the knob and getting a flame. The secret is hydrogen. An electrolyzer can use electricity to split water (H₂O) into hydrogen and oxygen. The hydrogen can then be used as a fuel to create heat for cooking. And here’s the fascinating part: when hydrogen burns, its main combustion product is water vapour. But there’s a catch: the stove isn’t getting free energy from water. Electricity is needed to produce the hydrogen in the first place. Hydrogen is an energy carrier, not an energy source. Researchers have already developed and tested hydrogen cooking-stove designs. The technology is real—but making it safe and practical for everyday homes remains an important challenge. The future of cooking may look very different from the kitchen we know today.
