Keston Boilers are ready for a 20% hydrogen blend

Whilst there is a lot of discussion and publicity around “hydrogen ready” boilers that can be converted from natural gas to run on 100% hydrogen, there is a mid-term solution that has the potential to reduce carbon emissions from domestic heating without requiring changing the existing appliances.

Current Keston boilers are ready to run safely on a 20% hydrogen blend with no technical adjustments. Look out for the ‘Ready for 20% Hydrogen’ icons across our website and social media:


What do we mean by a 20% Hydrogen blend?

Hydrogen is a “clean” gas that, when burned, doesn’t release carbon dioxide. It has the potential to provide energy for home heating and hot water with minimal disruption to the householder, who can still have a familiar gas boiler in their home.

A blend of hydrogen of up to 20% mixed with natural gas provides a steppingstone on the way to a full 100% hydrogen conversion of the gas grid, which is a longer term ambition and likely to occur from the mid-2030s onwards.

Blending up to 20% hydrogen into the gas grid with existing natural gas could save up to 6 million tonnes of carbon dioxide emissions every year.

A 20% hydrogen blend means that people can continue to use the gas supply as normal, without any changes being needed to gas appliances or pipework, while still reducing carbon emissions.
