Positive progress towards reducing UK C02 emissions

About HyDeploy

HyDeploy is a pioneering energy trial to establish the potential for blending hydrogen, up to 20%, into the normal gas supply to reduce carbon dioxide (CO2) emissions. It aims to be the first project in the UK to inject hydrogen into a natural gas network.

It will determine the level of hydrogen which could be used by gas consumers safely and with no changes to their behaviour or existing domestic appliances.

Subject to Health & Safety Executive approval, the aim is to run a year-long live trial of blended gas starting in 2019.

HyDeploy is being hosted at Keele University in Staffordshire. Click here if you live or work on the Keele campus, or would like to find out more about why Keele is the ideal place to host HyDeploy.

HyDeploy is funded by Ofgem’s Gas Network Innovation Competition, Cadent and Northern Gas Networks.

Why do you want to inject hydrogen into normal gas?

The UK is committed to a reduction in carbon dioxide (CO2) emissions of 80% by 2050.

Over 80% of UK homes are heated by gas, with heat accounting for around one third of UK CO2 emissions. Progress has been made to decarbonise electricity, but very little on decarbonising heat.

Although the gas network already delivers some green gases, like biomethane, further research is needed to understand the potential of other zero or low carbon gases to meet heat demand.

HyDeploy is one of a number of research projects investigating the potential of hydrogen to help meet this challenge.  Many experts see hydrogen as an adaptable alternative to fossil fuels. This is because when hydrogen is burned it doesn’t produce CO2, just water and heat. This means it could be a way to deliver low carbon energy.

The results of HyDeploy could provide a platform for a trial on a public network, and wider roll out.

A collaborative project

HyDeploy is being delivered by the HyDeploy consortium, which brings together a variety of technical expertise and practical experience.


Consortium members:

Cadent Gas Limited, Northern Gas Networks, Keele University, Health & Safety Laboratory, ITM Power and Progressive Energy.


Delivery of HyDeploy is also supported by gas safety testing specialists Kiwa, gas industry experts Dave Lander and technical consultants Otto Simon Limited.

What is happening now?

HyDeploy is currently in Phase 1 which runs to June 2018.

Activities during this phase:

  • Engaging with homeowners, residents and building users at Keele University about HyDeploy.
  • Laboratory testing of common household gas appliances and materials on the gas pipe network by the Health & Safety Laboratory, Kiwa and Keele University, to understand how they perform with different level of hydrogen.
  • Safety checks on gas appliances in homes and buildings in the proposed HyDeploy trial area at Keele. Click here if would like to find out more about these safety checks.

A live trial of hydrogen blended with normal gas at Keele will only go ahead with approval from the Health & Safety Executive (HSE). The HSE must be satisfied that the blended gas will be as safe to use as normal gas.

The evidence from the safety checks in homes and university buildings and results from laboratory tests will help the HSE:

  1. make a decision about whether a live trial can go ahead safely; and
  2. confirm the appropriate level of hydrogen that can be used (up to 20%).
