A hydrogen fuel cell can power a house, but today it is rarely worth it. A house needs a lot of energy over a whole winter, and storing all of it as hydrogen costs a lot.
What a Swedish test showed
In 2020, a house near Skellefteå in northern Sweden was cut off from the grid. It used solar panels, batteries, an electrolyser, a hydrogen store and a fuel cell. Today the house is back on the grid in winter, and the hydrogen store is not used. The owner, Skellefteå Kraft, said the solution is not current for private homes because of cost and demand (Elinstallatören, 27 October 2026).
Where hydrogen fits better
Small loads far from the grid, such as a telecom mast or a sensor station.
