Hydrogen House Is ‘Greenest In Europe’

The title of this post is the same as that of this article in The Times.

This is the introductory paragraph.

A hydrogen-powered house that is off-grid and said to be the first of its kind in Europe is being built by a family in Devon.

These are some features.

  • Solar panels
  • Hydrogen from electrolysis.
  • Hydrogen storage
  • Hydrogen boiler
  • Water from a borehole
  • Own sewage plant
  • Air source heat pump.

The article says that “Any spare hydrogen can power the hydrogen cars they plan to buy”

This sounds like my ideal house!

  1. Fine for an individual dwelling in its own grounds but in a city of many millions?

  2. I read the article this morning. Most of these things they are doing are going into my new house that is currently under construction (the roof tiles are going on this week (80% slate in a resin). The exception is the hydrogen system. They won’t need the hydrogen boiler with the Passivhaus standard, and would be better to use heat pump technology to heat water (CoP>4) and phase change heat stores, to store heat for washing and heating, when the sun doesn’t shine (e.g. at night), I doubt that the hydrogen system is 400% efficient, so getting the multiplier would be useful. Currently, I think that battery storage is a more tried and tested technology than hydrogen for domestic use, especially if it is not required for heating and hot water, I do wonder how much electricity they can actually generate on a very overcast period in the middle of winter. They will need a lot of peak power to liquefy hydrogen. I guess it depends on how much energy they could store as hydrogen to cover such periods, and how long the low generation period lasts. Not a dependency would want, but then I haven’t done the sums for hydrogen. It will be interesting to see how it goes.

    • I don’t think, they will be liquifying the hydrogen. But storage is getting extremely efficient.
