Cartrefi Hydrogen Homes Project
Welcome to Wales' first hydrogen home

We've been working with Codi Group, IGEM, KIWA and British Gas to retrofit a traditional Welsh terraced home with a 100% hydrogen boiler and cooker.

The project is a UK first, exploring how hydrogen – a cleaner, greener energy source – could be used to heat our homes in the future. The project looks at how existing homes can be easily retrofitted with appliances powered by 100% hydrogen, with minimal cost and disruption to you.

Transforming a traditional terraced house

Working with social housing landlord, Codi Group, we transformed a former social dwelling with a deep retrofit - including new energy efficiency measures. The old natural gas boiler and hob were replaced with 100% hydrogen appliances. The home now runs like a typical house.

Why Cartrefi Hydrogen Homes?

This project isn't part of a wider plan to convert local homes to hydrogen - it's an evidence gathering project to test how hydrogen works in a real life home.

We know it's safe and a good alternative to natural gas, but this demonstrator helps us see how it fares for heating and cooking.

  • Does the home warm up quickly?
  • Do the appliances use the same or more gas?
  • Will food cook in the same way?

Cartrefi Hydrogen Homes is a first step to help tackle how we reduce carbon emissions from the 26.4 million properties in Wales and England.

Over 85% of UK homes use natural gas for heating and cooking, which produces around a fifth of our total carbon emissions.

The project is a UK first, exploring how hydrogen – a cleaner, greener energy source – could be used to heat our homes in the future. The project looks at how existing homes can be easily retrofitted with appliances powered by 100% hydrogen, with minimal cost and disruption to you.

Decarbonising home heating is an essential step for Wales and the rest of the UK reaching its net zero targets, and we are committed to being part of the solution.
