It says the infra and boilers are ready in the pilot. The infra has been built and homes are being connected after Xmas. Safety reviews have been passed. The pilot includes offshore wind producing hydrogen. 

Hydrogen boilers for domestic use are entirely a fossil fuel industry con so far as I can understand it.  To produce green (ie carbon free) hydrogen you need to use electrolysis (ie electricity) with a conversion efficiency of about 70%.  If you used the same electricity to power a heat pump you have a conversion efficiency of 300%.  It simply doesn't make sense for domestic heating so far as I can see.

That's not to say hydrogen doesn't have a place, in energy storage and for applications where you need a very high energy density, but never for domestic heating.

If someone can explain the economics differently Im prepared to change my mind.

 

 

 


4kW peak of solar PV since 2011; EV and a 1930s house which has been partially renovated to improve its efficiency. 7kW Vaillant heat pump.
