HII Resources
These resources are available to support an understanding UK hydrogen technology innovation and development of supply chains development.
The content from our twelve partners is designed to provide an understanding of the UK’s opportunity to be a global leader in hydrogen technology and the work being done across research, industry and government to help UK technology power the global hydrogen economy.

Unlocking the hydrogen market
In this article, we (HII) delve into the complexities of small-scale hydrogen distribution, exploring the impact of existing challenges, and the promising solutions emerging in the UK.
Debt financing low carbon hydrogen projects in the UK
Projects in energy markets often use debt financing because it is cheaper than equity and enables rapid scaling. The question this report set out to answer is whether low carbon hydrogen projects can/are able to access this type of funding.
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.

A Net Zero Powerhouse
As the UK powers onward 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 is needed.
At the HII, we aim to scale up technology across hydrogen production, distribution and use to transform the UK into a Net Zero Powerhouse.
