How can the UK produce enough hydrogen at the right costs in the future? We look at what the data tells us so far...
When it comes to understanding what role hydrogen can play in reducing our carbon emissions, our Gas Goes Green Pathway identified homes and businesses’ heating, hot water and cooking as the UK’s single biggest use of energy in 2050, requiring 298TWh each year.
To put that in context, that’s the equivalent annual electricity output of nearly 12 Hinkley Point C nuclear power plants, which cost about £25bn each to build.
In that Pathway, we set out the role that hydrogen, biomethane and electricity have to play, finding that using a mixture of low or zero carbon energy sources to reduce our carbon emissions will save the UK economy £13bn a year, compared to the alternative of just using electricity by itself.
So, can we produce enough hydrogen for it to play its part, and what are the costs and benefits of doing so?
Let’s take the first question.
We believe that the UK can, setting out in Britain’s Hydrogen Network Plan how and when gas network companies can deliver the infrastructure required to do so.
Important progress is now being made on the technical engineering elements of this work, through progress on hydrogen blending and hydrogen village trials, as well as our gas network innovation projects, which will deliver jobs and investment around the country.
Which leaves the second question – what are the costs and benefits of producing enough hydrogen to do so?
We’ve used a wide range of independent, industry leading data sources to look at this question, including information from the Department for Business, Energy and Industrial Strategy, the Committee on Climate Change, National Grid and Bloomberg, amongst others.
In addition to the £13bn a year saving identified by the Gas Goes Green Pathway, our research found that investment in building the hydrogen production capacity that we need to for us to hit our Net Zero emissions target will unlock a total of £116bn of savings for billpayers by 2050, compared to the alternative of continuing to use natural gas.
In particular, green hydrogen produced from excess renewable power is expected to become rapidly cheaper. Towards the end of this decade, we expect to see the costs of it falling to around the same as using natural gas, because of drops in the costs of building infrastructure and falling electricity wholesale prices, due to increased levels of renewable electricity generation.
Crucially, we think that Government support for green hydrogen will ensure that the long-term cost benefits of it are achieved. Our research shows that the costs of producing it can fall in a similar way to the costs of electricity produced from solar and offshore wind, which have reduced dramatically over the past decade. And under this scenario, methods for producing both blue and green hydrogen become cost-competitive with natural gas (plus the cost of carbon) by 2035.
So, when it comes to using hydrogen in our homes to help people reduce their emissions, we’re optimistic about the future ahead. We’ve got the world-leading technical expertise and know-how to ensure that’s delivered safely and securely, and it’s clear from the data in front us today that that UK can produce the hydrogen needed o turn that into a reality, at the right costs, demonstrating how tomorrow’s heat is today’s opportunity.
Notes to editors
Gas Goes Green #H2Explainers are a series of blogs setting all the key information you need to know about how Britain’s gas networks are working to deliver hydrogen to our homes, as part of our 'Tomorrow's Heat, Today's Opportunity' campaign.

About Energy Networks Association
We’re the industry body for the energy networks. Our members own and operate the wires and pipes which carry electricity and gas into your community, supporting our economy. The wires and pipes are the arteries of our economy, delivering energy to over 30 million homes and businesses across the UK and Ireland. To do this safely and reliably, the businesses which run the networks employ 45,000 people and have spent and invested over £60 billion in the last eight years.
