Hydrogen Innovation Initiative
Making Hydrogen work for the UK
HII Mission
We are committed to our vision of UK technology powering the global hydrogen economy, transforming our industry into a Net Zero Powerhouse.
Our mission is supporting UK industry to anchor high-value jobs, boost resilience and drive decarbonisation by accelerating the development of critical technologies and supply chains for the fast-growing hydrogen economy.
Driving Innovation
HII has been set up to drive industry-led Hydrogen innovation across:
Generation
Accelerating renewable and low-carbon hydrogen production.
Distribution
Developing safe and efficient hydrogen distribution technologies.
Consumption
Developing new hydrogen applications in power, transport, industry, and heating

Industrial Sectors
Coordinating across 11 industrial sectors
Hydrogen Production
Hydrogen distribution and storage
Energy networks
Offshore
Renewables
Foundation industries
Chemical industries
Power generation
Aerospace
Automotive
Maritime
Technology Areas
The Hydrogen Innovation Initiative is working to accelerate the development of nine key technology areas for hydrogen production, distribution, and consumption.
Hydrogen Production Technologies
Methods to produce low carbon hydrogen, as defined by UK low carbon hydrogen standard.
Propulsion and Power Generation
The use of hydrogen for propulsion or to generate power, either through fuel cells or combustion engines.
Conditioning
Preparation of hydrogen for distribution and use, including compression, liquification and purification.
Distribution and Control
Components required to safely distribute and deliver hydrogen, covering both infrastructure and on-vehicle.
Heat Generation
Use of hydrogen for heat, considering industrial, commercial and domestic applications.
Hydrogen as a Feedstock
Hydrogen used as a feedstock in production processes including chemical processing and material production.
Hydrogen Storage
Storage of hydrogen as a gas, liquid or using carriers, for numerous scales and applications.
Thermal Management
Thermal management required for hydrogen end to end.
Monitoring and Metering
Using sensors and monitoring systems to ensure the safe and efficient operation of hydrogen systems.
Who We Are
HII is a trusted group of organisations working with Industry, Government, and academia to create an investible, globally competitive hydrogen technology and services sector, here in the UK.
A Collaborative Approach
11 organisations, 40 locations across the UK, 5000 people, coordinating across industrial sectors to deliver this shared mission.
Resources
As the industry powers onwards to Net Zero, the way we produce, use and store energy is changing. Our power, heating and transport systems must decarbonise if we are to achieve this target, and so a mix of low-carbon, renewable energy sources are needed.
ORE CATAPULT REPORTS: Deep Green Hydrogen
In partnership with the Hydrogen Innovation Initiative (HII) and Pembrokeshire Council, ORE Catapult is helping to spread awareness around green hydrogen – and this new study, Deep Green Hydrogen, delves into the benefits of hydrogen in agriculture.
Key barriers to the development of hydrogen in the UK energy system
As part of the Innovate UK funded Hydrogen Innovation Initiative (HII) Seed project, the Energy Systems Catapult and the University of Birmingham undertook a series of interviews and analysis towards the end of Q1 2023 to identify and collate barriers to using hydrogen in the UK energy system for Net Zero.
Hydrogen: a key enabler for meeting net zero goals.
We need to ensure the UK has the right skills, at the right time and in the right place to maximise the opportunity that hydrogen presents as a key enabler for meeting net zero goals. Boost your understanding with the HVM Catapult’s open access modules
How to decarbonise the most challenging areas of the UK economy?
This thought leadership piece made the case for establishing the Hydrogen Innovation Initiative. It discusses how advances in hydrogen technology will play a critical role in delivering net zero.
Offshore Wind and Hydrogen: Solving the Integration Challenge
This report looks at the opportunities and challenges associated with integrating high levels of renewables in to the electricity grid, and makes a strong case for the synergies between offshore wind (OSW) and green hydrogen production
Enabling activity for multi-GW offshore wind and hydrogen deployment in the Celtic Sea
This report focuses on preparing the Milford Haven region for longer term trends (longer time-horizon energy generation) and is part of a wider suite of documents related to this study
Exploring the potential interactions between floating offshore wind and hydrogen
This report examines the challenges and future opportunities for floating offshore wind and green hydrogen for the integration to the electrical grid infrastructure. The potential combination of both floating offshore wind and hydrogen have received significant interest from the UK Government and this report examines that potential.
