This issue of Global Hydrogen Review explores the full hydrogen value chain, from low-carbon production and advanced electrolyser technologies to transport, storage, and refuelling. It highlights innovations in materials, pipeline networks, and liquid hydrogen solutions, while addressing safety, efficiency, and strategies to scale hydrogen for a net-zero energy future.

This month's front cover is brought to you by Global Hydrogen Review.

The evolving landscape of hydrogen in the UK
Conrad Purcell, Shu Shu Wong, Kayley Rousell, and Zainab Al-Qaimi, Haynes Boone, UK, debate the hydrogen landscape in the UK and the steps being taken to increase its development.

The hydrogen value chain: scalable pathways to low-carbon production
Aurelia Pipino, Giovanni Genova, and Pietro Moreo, Casale, introduce different pathways for sustainable hydrogen production.

Stay on course!
Håkon Volldal, Nel Hydrogen, posits the necessity of hydrogen for a secure energy future that will reap benefits for humanity.

Electrolyser evolution
Josef Macherhammer and Dr Alexander Schenk, AVL, Austria, compare different electrolyser technologies, highlighting their market status, efficiency, and operational characteristics.

Rethinking materials
Kerry Drake, Le Song, Philippe Alienne, and Pragati Verma, Greene Tweed, explain how cross-linked PEEK materials can play a critical role in advancing components used in hydrogen infrastructure.

Turbocharging hydrogen transportation
Reza Agahi and Behrooz Ershaghi, Nikkiso Clean Energy & Industrial Gases, USA, consider the design of turboexpanders in primary and deep cryogenic refrigeration cycles.

Enabling the hydrogen shipping revolution
Daniel Patrick, Atlas Copco Gas and Process, USA, considers how centrifugal compressor technology is being scaled to support liquid hydrogen carriers and help manage boil-off gas during transport.

Paving a path to zero-loss hydrogen refuelling
Aaron Lapsley, Hyroad Energy, considers how to solve the problem of losses that occur during liquid hydrogen storage and refuelling operations.

Unlocking the power of liquid hydrogen
Greg Gosnell, GenH2, USA, discusses why zero-loss liquid hydrogen technology will be key to large scale mobility fuelling.

Bridging the gap to mass production of liquid hydrogen
Dr Rajendran Parthipan, Dr Barry Prince, and Dr Neil Glasson, Fabrum, New Zealand, highlight the design, functionality, and applications of small scale hydrogen liquefaction in an industry focused on large scale solutions.

Hydrogen safety and detection
Andrzej Janowski, MSA Safety, Poland, discusses the safety considerations, challenges, and technology applications of hydrogen.

Advancing the global hydrogen pipeline network
Garry Hanmer, Atmos International, UK, explores some of the challenges facing hydrogen transport through pipelines, and how to implement solutions for safe and reliable operations.

Building the nervous system of the hydrogen grid
Suji Kurungodan and Dr Andrew Stevenson, Sustainable Pipelines Ltd, discuss a shift to usher in the net zero era with intelligent, flexible, high-performance pipeline network infrastructure.
