Hydrogen Capability Network

Securing a competitive advantage for UK aerospace through a world leading collaborative network. Delivering a coherent approach to skills development, infrastructure and hydrogen supply to secure long-term UK capability.

The Hydrogen Capability Network (HCN) is collaborating with sector stakeholders to develop key recommendations from FlyZero and determine the immediate priorities for action.

Established in April 2023 backed by the Department for Business and Trade (DBT), the HCN’s aim is to ensure that there is collaboration, coherence and efficiency for the aerospace sector to enable hydrogen research and development.

It is focussing on test and demonstration infrastructure, fundamental and enabling research, and hydrogen skills. The HCN works on behalf of the sector through a network of stakeholders and delivery partners.

The initial phase of the HCN project concluded in April 2024 and the ATI, with DBT, has now launched a new phase of work. This will take forward the immediate priorities into delivery, and develop proposals and recommendations for the longer-term strategic needs of aerospace R&D.

Recommendations on the longer-term strategic interventions required to enable liquid hydrogen (LH2) powered flight will be published in mid-2025.

Hydrogen Capability Network news

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:

  • Test infrastructure: Establish at least two open access hydrogen test hubs to provide the required testing infrastructure, LH2 supply and expertise to satisfy UK aerospace priority test needs.
  • Research: Conduct a four-year strategic research programme on Cryogenic Hydrogen Materials Testing Standards (CHyMES) to enable product design and certification.
  • Skills: Launch pilot initiatives to accelerate action on skills and coordinate the sector’s skills needs in cryogenics and LH2

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.

The ATI’s Hydrogen Capability Network (HCN) has unveiled five initial interventions to accelerate the hydrogen economy in UK aerospace as the 12-month Phase 0 of the programme passes the half-way stage. The team delivered a webinar on 12th December to share more information on the progress of programme and to provide an overview of the five recommended interventions which are being developed by the team. The five intervention areas are:

  1. Research Landscape
  2. Materials Testing & Standards
  3. Liquid Hydrogen (LH2) Test Hubs
  4. LH2 Supply
  5. Skills & Training

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:

  • A joint workshop with the Aerospace Growth Partnership (AGP) to understand skills gaps and demand for aerostructures took place on 12th July. Three further workshops are planned on gas turbines, fuel cells and electrical systems and systems integration (including tanks and fuel systems) with dates to be confirmed.
  • We are working with cross-sector hydrogen organisations on future skills requirements including the Hydrogen Innovation Initiative (HII) and the Hydrogen Skills Alliance (HSA). Liquid hydrogen (LH2) technology, skills and research is still immature meaning collaboration is required to accelerate learning.
  • A workshop is planned for Wednesday 13th September with UK Aerospace Research Consortium (UK-ARC) to identify gaps in research to support LH2 flight.
