Hydrogen Innovation webinar series 2025

The Hydrogen Innovation Initiative (HII) partnership invites you to a series of four webinars in Autumn 2025.
The webinars are free to attend and are targeted at innovators, technicians, engineers, students, and others with an interest in hydrogen technology. We hope you can join us!

Sessions

Friday 19 September 9am-10am
Modelling the hydrogen future

This webinar will showcase how cutting-edge modelling and digital tools are shaping the UK’s hydrogen future. The audience will hear from three HII partners. Energy Systems Catapult’s topics will range from insights on flexibility and storage, to mapping the UK’s hydrogen modelling landscape.

They will explore how data-driven analysis is unlocking opportunities across the value chain and will give a preview of future project outputs.

Digital Catapult will present their work on digital certification of green hydrogen.

The National Physical Laboratory (NPL) will present their work on modelling manifold effects in alkaline water electrolyser stacks.

Friday 26 September 9am-10am
Hydrogen for transport applications

In this webinar, Connected Places Catapult will share an overview of the opportunities for hydrogen and its derivatives in transport, and explain how these are being brought closer to reality through real world trials and demonstrations.

The presentation will highlight work delivered as part of the Hydrogen Innovation Initiative, including aviation related projects funded through the HII Demonstration programme, flagship activities such as ZEHID for zero-emission heavy goods vehicles, and maritime projects exploring green shipping corridors.

Compound Semiconductor Applications Catapult will present their work on semiconductors for fuel cell applications.

Satellite Applications Catapult will give an overview of hydrogen applications in space.

The Advanced Propulsion Centre (APC) and IAAPS will each present an overview of their relevant hydrogen activity.

Friday 3 October 9am-10am
Hydrogen production and offtake considerations

Offshore Renewable Energy Catapult (OREC) will demonstrate their work within the Hydrogen Innovation Initiative (HII), which aims to advance green hydrogen production by reducing the cost, risk, and complexity of electrolyser grid compliance testing.

They will discuss replacing physical electrolyser stacks with an emulated Electrical Equivalent Circuit (EEC) model. Built from experimental data collected on the HyFive system, the model reproduces resistive, capacitive, and dynamic behaviours and is integrated into a Power Hardware-in-the-Loop (PHIL) framework on OREC’s mini-eGrid.

This method validates electrolyser performance without hydrogen generation, enabling safer, faster, and more reliable testing, accelerating large-scale deployment of green hydrogen technologies.

During the same webinar, Net Zero Technology Centre (NZTC) and Glass Futures will each present an overview of their relevant hydrogen activity.

Friday 10 October 9am-10am
Hydrogen storage solutions for different scales

Storage of hydrogen is a complex issue due to the physical properties of hydrogen. The topic is complicated further by the many different scales of storage required – from large scale, long-term storage for grid balancing purposes, down to small scale, short-term storage for transport applications.

During this webinar, experts from Energy Systems Catapult, Connected Places Catapult and High Value Manufacturing Catapult (HVMC) will explore the requirements, challenges and solutions for hydrogen storage.

Energy Systems Catapult will talk about large scale hydrogen storage, in particular salt cavern storage.

Connected Places Catapult will explore the considerations for small scale hydrogen use including storage.

High Value Manufacturing Catapult will go into detail on the advanced composite manufacturing and testing technology that is being applied for composite cryogenic hydrogen storage tanks.
