The ATI’s Hydrogen Capability Network is inviting metal suppliers to contribute materials and expertise to a new cryogenic hydrogen testing initiative.
In May 2024 the ATI’s Hydrogen Capability Network (HCN) announced a four-year strategic research programme on Cryogenic Hydrogen Materials Testing Standards (CHyMES) as one of three key priorities.
This programme, being developed in partnership with the National Physical Laboratory (NPL), aims to enable product design and certification covering test standard development for the evaluation of mechanical, thermal, and physical material properties. Full details of the CHyMES programme activity and outputs are available in this presentation.
Now, the HCN is looking to engage with metal material suppliers who could supply free-of-charge materials into the programme and become part of the project steering board. The HCN steering board is an opportunity to be part of reviewing the outputs as they evolve and advising the project team.
A range of standard metals is required including 300 series stainless steels, aerospace grade Al alloys and Nickel alloys, to allow the data to be open access and comparable to existing literature values. Ideally, suppliers would be UK based, and the material will be in sheet, bar or rod format.
If you are interested in this opportunity, please contact the HCN’s Materials Fundamental Research Lead, Cameron Blackwell at Cameron.Blackwell@ati.org.uk. If you’re not able to contribute materials but would still like to engage with the HCN, email hydrogen@ati.org.uk.
Launched in April 2023 and funded by the Department for Business and Trade, the HCN is an ATI project set up to identify and deliver the key requirements to accelerate the development of a new era of liquid hydrogen-powered flight in the UK. The HCN mission is to secure long-term UK capability in zero-carbon emission aircraft and a competitive advantage for the UK aerospace sector. Continuation of the programme has been confirmed to at least April 2025.
The ATI’s Hydrogen Capability Network is bringing experts together solve key challenges to realising hydrogen-powered aircraft. Discover the outcomes from HCN research workshops on cryogenic health and safety, thermofluids and materials.

Helen Brocklehurst, Head of Skills & Research at the ATI’s Hydrogen Capability Network (HCN), discusses the gaps and priority areas for UK aerospace in the hydrogen skills landscape.
In the past year, the message from industry has been that organisations are struggling to recruit suitably qualified and experienced people to support the development of liquid hydrogen fuel storage and delivery systems on aircraft. In response, the HCN is recommending a set of pilot initiatives to accelerate action on skills and coordinate the sector’s skills needs in cryogenics and LH2 systems.
Over the next year, we will be working with government to set up and deliver the following initiatives:
These initiatives have been identified through talking to industry and have been inspired by tried-and-tested strategies from other sectors, including the Nuclear Skills Academy, the Faraday Institution for battery technologies and the Alan Turing Institution.
Alongside this, the proposed hydrogen hubs and CHyMES project will provide opportunities for ‘learning by doing’ and will increase the sector’s knowledge, capability, and familiarity with dealing with cryogenics.
The HCN is planning a research conference to bring together UK experts in the field of cryogenic hydrogen materials, thermofluids and health & safety to share knowledge and expertise, build a community and signpost aerospace as a career path. This is likely to be held in the week commencing 6th January 2025 in or around London.

Nour Eid, Head of Strategy & Commercial at the ATI’s Hydrogen Capability Network, discusses the gaps and priority areas for UK aerospace in the hydrogen test infrastructure landscape.
Last month the HCN published Securing Liquid Hydrogen Capability in the UK, in which we recommended the establishment of UK hydrogen test hubs to provide the required testing infrastructure, Liquid Hydrogen (LH2) supply and appropriate health and safety handling requirements to satisfy the UK aerospace sector’s test needs.
Over the next 12 months, we will be starting work to secure the building and commissioning of two hubs – one at the Health and Safety Executive (HSE) in Buxton, and another at Airbus’ Zero Emission Development Centre (ZEDC) in Filton. These hubs will play a crucial role in meeting the technical and strategic requirements for UK-based infrastructure identified during the first 12 months of the HCN programme.
In the past year we have collated the demand signal for LH2 testing in the UK. This has been informed by the testing plans from industry and has included the technical and strategic requirements for UK-based infrastructure. As part of this analysis, we looked at the immediate needs for testing at large volumes and with high LH2 flow rates. This led to the conclusion that bespoke hydrogen test hubs are required in the UK to meet this testing demand. Both proposed hydrogen hubs will have an open-access model, allowing research and testing to be undertaken by UK entities who want to test in a representative LH2 environment.
The HCN’s forecasted demand currently shows a quarterly average usage of 11-22 tonnes of LH2 until around 2030. This is the equivalent of approximately 3 tankers delivering LH2 into the UK each month.
Alongside the development of test hubs, we also identified a requirement to develop infrastructure for materials testing and development of standards. More information on our approach to can be found in our previous
The UK is at a turning point when it comes to hydrogen research and the HCN is keen to work with others in the community who are developing their hydrogen infrastructure. Testing at various scales has different requirements, and our objective is to create a network of UK test infrastructure that is complementary to each other and provides the sector with sufficient capacity and appropriate capability to satisfy the test demands.

A strategy for the future
Over the next 12 months we will be compiling a strategy that will consider what is required to support hydrogen testing in the UK over the next decade. This will identify the long-term requirements for larger-scale hydrogen testing, certification and demonstration in a representative airport environment. This will also include the UK’s supply of LH2 and exploring price incentive mechanisms with Government.
We aim to keep working with colleagues within the UK aerospace sector, and those working in other sectors to best understand where intervention is required and how the HCN can support.
Huw Edwards, Hydrogen Cryogenic Specialist at the ATI’s Hydrogen Capability Network, discusses the process of identifying gaps and priority areas for UK aerospace in the cryogenic hydrogen research landscape.
One of the key areas of focus for the initial phase of the ATI’s Hydrogen Capability Network (HCN) has been the cryogenic hydrogen research landscape – specifically identifying the key gaps in knowledge and fundamental research that are limiting the development of a liquid hydrogen commercial aircraft.
Our initial focus has been on the aircraft fuel system, as we feel this is the most disruptive and least mature technology. The use of liquid hydrogen to date has been limited across all industries and there are a multitude of requirements in aircraft fuel systems that are new to liquid and cryogenic fluid management.
Very early on it became clear that one of the key factors limiting technology development in the UK is the lack of material property data for materials at liquid hydrogen conditions, and compounding this is the lack of validated or standardised test methods to generate this data. For the current ambitions of industry to bring aircraft into service by 2035 many cryogenic technologies need to achieve TRL 6 before 2030. This means materials testing and standards need to be developed as soon as possible.
The development of standards and test methods is a non-competitive area, which means it can be carried out collaboratively and bring the entire industrial and research community together. Building this knowledge will benefit the entire UK supply chain, unlock further R&D and build a broader UK skills base around cryogenics and LH2.
To tackle materials testing we have worked in partnership with the National Physical Laboratory (NPL) and interfaced with industry and academia to develop a research programme on Cryogenic Hydrogen Materials Testing Standards (CHyMES). The CHyMES project is a 4-year collaborative strategic research programme with the objectives of developing, validating and standardising materials test methods – and to provide the UK supply chain with these methods, initial material property data and enhanced knowledge around cryogenics. We will continue the partnership with NPL to co-lead the programme and work across universities and other research organisations to deliver this work.
As part of our analysis around cryogenic material testing, the HCN is also co-authoring a report with NPL to provide an overview of the international landscape in this area. This will be published later this year but an overview of the recent collaboration can be found here.
Having identified materials test methods as a critical gap, we began to survey the rest of the landscape to identify other key gaps. We held workshops and consultations with industry and academia, and concluded that an overarching strategy is needed to align cryogenics and LH2 research activity with the sector’s industrial requirements.
Through those workshops, the HCN has highlighted the following topics as priority strategic research areas that the UK needs to develop. Over the next 12 months we will be working with subject matter experts to scope and develop research projects in the following areas:
Alongside this, we will be designing a longer-term joint funding programme to support priority research topics that might arise in the future. We will continue working with colleagues in EPSRC, UKRI and other organisations who will help shape this longer-term vision.
To find out more about our work developing the UK’s research base and how we came to these conclusions, the following report is available to read and download:
The Hydrogen Capability Network plans to develop a pre-normative collaborative research proposal to boost the UK’s capabilities in cryogenic hydrogen. To support this, we are requesting bids for funded work packages: desk-based assessments of which organisations globally are active in this field, their capability and maturity, and specifically their experimental and modelling capabilities.

The ATI’s Hydrogen Capability Network (HCN) is to focus on test infrastructure, research and skills as the three key enablers to hydrogen-powered aircraft technologies with the programme’s first report published today.
Launched in April 2023 and funded by the Department for Business and Trade, the HCN is an ATI project set up to identify and deliver the key requirements to accelerate the development of a new era of liquid hydrogen-powered flight in the UK. The HCN mission is to secure long-term UK capability in zero-carbon emission aircraft and a competitive advantage for the UK aerospace sector. Continuation of the programme has been confirmed to at least April 2025.
Over the past 12 months, the HCN has developed the key recommendations from the ATI’s FlyZero project, which identified liquid hydrogen as the zero-carbon emission fuel with the greatest potential to scale to large commercial aircraft. Recommendations taken forward by the HCN include examining liquid hydrogen (LH2) demand, R&D test requirements and UK capability gaps.
Industry Minister Alan Mak said: “The potential for using hydrogen as fuel is huge for the future of aviation, and we want our world-leading aerospace sector at the forefront of this new and emerging industry of zero emission air travel.
“I’m pleased to see the progress the ATI is making in leading the way on this cutting-edge work in its new report, helping our aerospace industry soar to new heights and supporting thousands of jobs while growing our economy.”
In its first report ‘Securing Liquid Hydrogen Capability in UK’, the HCN has identified the three immediate priorities for action:
Delivering the three immediate priorities provides the UK with a strong foundation to achieve the longer-term ambitions for the UK hydrogen aerospace ecosystem: larger-scale testing, demonstration in an airport environment and ultimately the design and manufacture of liquid hydrogen aircraft technologies.
Laura Cuss, Programme Director, said: “Liquid hydrogen-powered aircraft are key to aviation’s decarbonisation journey and achieving Net Zero 2050. This revolutionary technology shift for aviation requires unprecedented coordination and collaboration between government, industry and academia to maximise UK market share.
“By establishing hydrogen technology test and demonstration infrastructure, progressing research priorities and tackling the skills gap, the HCN will ensure a coordinated approach to accelerate the development of hydrogen aircraft technologies in the UK.”
The HCN is also setting out to develop an overarching sector strategy and recommendations for longer-term strategic interventions for hydrogen research and development in the UK. This will include what interventions are required in the long term to further develop this ecosystem as understanding and testing becomes more mature.
This strategic overview will complement the ATI’s technology strategy Destination Zero, which focuses on priority technology areas for investment through the ATI Programme. It will also align with the work of the Jet Zero Council, which is investigating sustainable aviation fuels (SAF) and the regulatory framework required to deliver zero emission transatlantic flight within a generation.
The ‘Securing Liquid Hydrogen Capability in UK’ report is available to download now on the ATI website, together with detailed reports on skills and research.

More than 50 attendees from over 15 Universities and RTOs joined a research workshop at the AIRC at Cranfield on Wednesday 13th September. Delivered by UK-ARC and the ATI Hydrogen Capability Network, the event focused on the research challenges associated with delivering hydrogen powered flight.
The morning session focused on showcasing the current UK research capabilities in hydrogen aerospace related topics, including propulsion, combustion, hydrogen safety, electrical and fuel cells, hydrogen tanks and fuel delivery systems. The presentations will also help to generate a map of the UK capability landscape, which can be used to link together research and industry and stimulate new alliances.
Led by Cranfield University, the afternoon session discussed hydrogen ‘on the aircraft’ sub-topics and drew out a great number of contacts to help form research communities and build the narratives to reflect research knowledge and add project engagements.
The information will be digested with the aim of formulating plans to identify research gaps and generate plans to address these through closer collaboration supporting the Hydrogen Capability Network, growing the UK-ARC community and moving towards research project definition.
Virtual meetings and workshops are being considered to build on engagement opportunities from the event.
The ATI’s Hydrogen Capability Network is continuing to work on hydrogen skills and research capability with recent updates summarised below:
