Loughborough University has hosted a UK–Japan hydrogen summit bringing together around 60 representatives from manufacturing, energy, technology, research, and professional bodies.
The meeting examined hydrogen production, distributed generation, gas turbines, fuel cells, and the expansion of electricity-intensive infrastructure, including data centres and planned AI Growth Zones. Participants considered how equipment, investment, and energy infrastructure would need to develop if hydrogen is to move beyond isolated demonstration projects.
Organisations represented included the Hydrogen Energy Association, Kawasaki, Hitachi Europe, Mitsubishi, Panasonic UK, Toyota UK, RWE, Energy Systems Catapult, Cadent, Future Biogas, HiiRoc, GeoPura, Deloitte, and Intelligent Energy.
The summit was chaired by Dr Emma Guthrie and supported by Deloitte, RenewRisk, and Intelligent Energy. Presentations covered production routes, local generation, investment conditions, and the use of turbines or fuel cells where grid capacity cannot be delivered quickly enough.
Loughborough also operates practical energy infrastructure on campus, including battery and electrolyser container systems. Facilities of this kind allow researchers and industrial partners to assess how production, storage, conversion, and control technologies perform as an integrated system rather than as separate laboratory components.
Hydrogen remains one of the most contested elements of industrial decarbonisation because it offers potential in applications that are difficult to electrify directly, yet production cost, conversion losses, storage, transport, and access to low-carbon electricity continue to limit deployment.
Data centre growth changes the energy equation
The expansion of artificial intelligence has added urgency to the search for large, reliable power supplies. Data centres cannot operate around intermittent availability, while developers may face long waits for transmission upgrades, new substations, or reinforced local connections.
Backup power has traditionally relied on diesel generators, with primary demand met through grid connections and power purchase agreements. Fuel cells, hydrogen turbines, batteries, and local generation are now being assessed as alternatives or complements, especially where connection delays threaten construction schedules.
Equinix’s hydrogen backup power trial in Dublin demonstrates how operators are testing whether fuel cells can meet stringent availability requirements while reducing dependence on conventional standby generation.
Fuel supply remains a central constraint because low-carbon hydrogen produced through electrolysis consumes substantial electricity, while compression, transport, storage, and reconversion add further losses. Direct use of renewable electricity will generally be more efficient where an application can be electrified without unacceptable operational compromise.
Hydrogen is therefore likely to find its strongest role in selected processes involving high-temperature heat, long-duration storage, remote generation, or chemical feedstocks. Industrial clusters with several users may improve the economics of shared pipelines, storage, and production infrastructure.
Japan has invested heavily in hydrogen supply chains, fuel cells, turbines, transport applications, and import strategies, while the UK offers offshore energy capability, gas infrastructure, research expertise, and industrial demonstration sites. Collaboration gives equipment manufacturers and project developers access to a broader pool of operating experience.
Gas turbine developers are working on systems capable of burning hydrogen blends and, eventually, higher hydrogen concentrations, although combustion behaviour changes significantly as the fuel mix shifts. Flame speed, temperature, nitrogen oxide formation, materials, control systems, and safety arrangements all require further engineering.
Fuel cells avoid combustion and can produce electricity efficiently at distributed scale, but stack durability, capital cost, fuel purity, and maintenance continue to influence commercial viability. Different chemistries suit different temperature ranges and duty cycles, making system selection heavily dependent on the intended application.
Manufacturing sites must assess hydrogen within a wider energy strategy that includes grid availability, electricity prices, heat demand, operating hours, resilience, carbon obligations, and future fuel costs. A technology that performs well in demonstration may still prove uneconomic across a complete asset life.
Similar constraints are shaping AI infrastructure, with grid delays already affecting the timetable for a major Essex data centre campus. Local generation can reduce connection pressure, but it does not remove the need for transmission reinforcement, storage, renewable generation, and demand management.
The next stage will require operating data rather than broad commitments. Demonstration systems must establish efficiency, availability, maintenance requirements, emissions, and cost under realistic duty cycles before hydrogen can secure a durable role in industrial and data centre energy systems.
