How trust makes the case for hydrogen home heating

Welcome to HyStreet

Why trust matters 

Hydrogen will play a central role in our future energy mix. But before hydrogen can be used to decarbonize the energy supply to homes, its safety has to be assured.

What is the story? 

Countries around the world depend on natural gas for heating and cooking but to meet global climate targets we need to decarbonize the energy system. Hydrogen is set to play a central role - 62% of senior energy professionals tell us that hydrogen will be a significant part of the energy mix by 2030. 

The question is, is our legacy pipework suitable and safe as a delivery system for hydrogen? 

To explore this, DNV has built ‘Hy Street’ at its testing and research facility in Cumbria. This row of ordinary-looking houses is actually a safety testing ‘laboratory’ for the UK Government’s Hy4Heat programme, which aims to establish if it is technically possible, safe, and convenient to replace natural gas with hydrogen in residential and commercial buildings and gas appliances.

Hydrogen is key to decarbonize our energy system

From intention to policy

UK gas distributors are encouraging the UK Government to take the policy decision that hydrogen can be used as a low-carbon fuel for home heating. They want to repurpose their natural gas networks to transport hydrogen safely and effectively. This way, they can decarbonize their activities and support the UK’s goal to achieve carbon neutrality by 2050.

To be able to do that, we really need to be able to demonstrate that we have proved our safety case for hydrogen, and that it is as safe as natural gas.
