Blending Hydrogen With Natural Gas
Posted: Fri 03 Jan 2020, 00:47:35
Interesting projects underway in the UK; use surplus wind energy (mainly at night) to create hydrogen which is blended at 20% into the natural gas system via " a special injection and mixing unit which can be carefully controlled and monitored to ensure that the hydrogen and natural gas blend remains consistent as gas flows vary." No need to change out appliances or infrastructure, though some older iron pipes may need upgrading (already being done anyway).
About HyDeploy
HyDeploy is a pioneering hydrogen energy project designed to help reduce UK CO2 emissions and reach the Government’s net zero target for 2050.
As the first ever live demonstration of hydrogen in homes, HyDeploy aims to prove that blending up to 20% volume of hydrogen with natural gas is a safe and greener alternative to the gas we use now. It will provide evidence on how customers don’t have to change their cooking or heating appliances to take the blend, which means less disruption and cost for them. It will also confirm initial findings that customers don’t notice any difference when using the hydrogen blend.
First Phase
HyDeploy @ Keele is the first stage of this three stage programme. The UK Health & Safety Executive have given permission to run a live test of blended hydrogen and natural gas on part of the private gas network at Keele University campus in Staffordshire. It will be the first project in the UK to inject hydrogen into a natural gas network.
Second and Third Phases
Once the Keele stage has been completed, HyDeploy will move to a larger demonstration on a public network in the North East. After that, HyDeploy will have another large demonstration in the North West. These are designed to test the blend across a range of networks and customers so that the evidence is representative of the UK as a whole. With HSE approval, and success at Keele, these phases will go ahead in the early 2020s.
The longer term goal
Once the evidence has been submitted to Government policy makers, we very much expect hydrogen to take its place alongside other forms of zero carbon energy in meeting the needs of the UK population. .....

Dr Graham Cooley, CEO, ITM Power said: “I am delighted that this important pilot project is now operational. The increased use of hydrogen to decarbonise heat via the gas grid will perform a critical role in helping the UK to fulfil its ambitious climate change obligations. Indeed, the Committee for Climate Change has indicated that the UK will need between 6GW and 17GW of electrolysis in the next 30 years to store renewable power and provide renewable heat. Today’s announcement is a very significant step.”
UK’s first grid-injected hydrogen pilot gets underway
Ground-breaking UK hydrogen trial underway at Keele University
First time zero carbon hydrogen has been injected in the UK’s modern gas grid . 20% hydrogen/natural gas blend can cut CO2 emissions without the need to change gas appliances
The UK’s first live pilot to inject zero carbon hydrogen into a gas network to heat homes and businesses is now fully operational.
HyDeploy is a ground-breaking green energy trial at Keele University, Staffordshire, that could help Britain cut its carbon emissions and open the door to a low-carbon hydrogen economy.
The HyDeploy demonstration is injecting up to 20% (by volume) of hydrogen into Keele University’s existing natural gas network, feeding 100 homes and 30 faculty buildings. The 20% hydrogen blend is the highest in Europe, together with a similar project being run by Engie in Northern France.
