First UK trial of hydrogen blended gas hailed a success

HyDeploy, the first project in the UK to blend hydrogen into a natural gas network, hailed a success.

Customers used hydrogen blended gas safely in their homes and without the need to make any changes to their existing appliances.

Some 100 homes and 30 university building on a private gas network at Keele University received the blended gas for a period of 18 months which ended in spring 2021. The trial paves the way for larger demonstrations on a public gas network.

The results of the first phase of this groundbreaking green energy project, that could help Britain dramatically cut its carbon emissions and open the door to a low carbon hydrogen economy, have now been published.

Hydrogen produces no carbon dioxide when used, making it a viable alternative for heating homes and businesses to achieve the government’s target of net zero carbon emissions by 2050, unlike natural gas, which is responsible for over 30% of carbon emissions.

Steve Fraser, chief executive of Cadent said: ‘I would like to thank the customers at Keele University for their willingness to take part in this trial. HyDeploy is a groundbreaking collaboration and has demonstrated very clearly that consumers can safely receive up to 20% hydrogen blended with natural gas, without the need to make any changes to their existing appliances.

‘With eight in 10 of our homes in the UK heated by natural gas – it is an energy we are familiar with. Adopting hydrogen blending across the gas networks would save carbon emissions equivalent to removing 2.5 million cars from our roads – a huge step towards net zero.

‘Importantly customers experienced no disruption and felt positively towards using hydrogen blends and the trial. Blending hydrogen into the natural gas network is a critical stepping-stone in helping the UK reach net zero by 2050.’

Gas safety checks were carried out in the homes and buildings in the trial area. Laboratory tests were carried out on a range of gas appliances, as well as extensive research on the effect of hydrogen on the different materials found in the gas network and the appliances.

Keele resident Rob Meredith said: ‘I was excited to be a part of this trial. I found that using hydrogen blended had no impact on any of my gas appliances, and I carried on cooking and using my heating like normal.’

Professor Trevor McMillan, vice chancellor of Keele University, said: ‘We are delighted that Keele University has been able to play a crucial role in blending hydrogen into the natural gas network.

‘HyDeploy has been a perfect fit for Keele University’s sustainability ambitions as an institution we are proud to have been able to use our campus and involve our staff and residents in this landmark project.’

The success of the trial at Keele University has paved the way for a larger pilot project at Winlaton, near Gateshead where 668 houses, a school and some small businesses have been receiving hydrogen blended gas on a network operated by Northern Gas Networks (NGN) since early August 2021.

Mark Horsley, CEO at NGN, said: ‘The results delivered by the Keele project gave the health and safety executive the confidence to approve the first blending of hydrogen with natural gas on the public gas network. We are delighted that our customers in Winlaton are now using their gas as normal whilst playing a vital role in the decarbonisation of the gas network.

‘This next phase of HyDeploy will provide more vital evidence about the possibilities of blending hydrogen into the gas network across the UK, as an important stepping-stone to decarbonising heat.’
