Engineering and environmental consultancy Ricardo has secured innovation funding for a pair of rail energy projects in the United Kingdom, aiming to test how hydrogen traction and station-based multi-energy hubs could cut emissions and reshape the way railways interact with wider power networks.

Strategic Innovation Fund backs two rail-focused studies

According to information published by Ricardo, the company has received support for two rail sector studies through the Strategic Innovation Fund, a multiyear initiative designed to stimulate new approaches to energy networks across the United Kingdom. The funding forms part of a broader programme that allocates hundreds of millions of pounds to projects intended to modernise how energy is produced, moved and used.

The two Ricardo-led projects sit within a transport innovation stream that looks specifically at rail. Rather than financing large-scale construction, the awards are targeted at early-stage research, modelling and feasibility work that could guide later investment decisions. Publicly available material indicates that the Strategic Innovation Fund approach is structured in phases, beginning with short discovery exercises before moving successful concepts into more detailed feasibility and demonstration stages.

Ricardo’s proposals centre on the dual challenge of decarbonising train operations and improving how rail infrastructure connects with other parts of the energy system. The work is framed around the need to cut carbon emissions from transport while ensuring that any solutions remain practical and cost effective for network operators and passengers.

By focusing on research rather than immediate deployment, the funding is intended to clarify which technologies and operating models are most likely to deliver reliable, lower‑carbon rail services, particularly on routes and at stations where full electrification may be complex or costly.

Hydrogen traction under review on rural Scottish lines

One of the funded projects, described in Ricardo’s industry insights, examines the potential role of hydrogen and battery traction on rural Scottish railways. The study aligns with Scotland’s stated ambition to remove diesel passenger trains from its network, a target that has focused attention on alternative forms of low‑carbon propulsion.

The research is set against the backdrop of traditional electrification, which remains a proven option but can involve substantial upfront capital costs. Infrastructure such as overhead lines, substations and supporting civil works can be resource intensive, with embedded emissions from steel and concrete. Disruption to rail services during construction is another factor considered in the evaluation.

Ricardo and its partners are using two rural lines as case studies to compare multiple scenarios, including hydrogen-powered rolling stock, battery trains and conventional overhead electrification. The analysis aims to assess not only direct emissions but also lifecycle environmental impacts, operational flexibility and long-term cost implications for the public purse.

Results from this phase are expected to inform whether a more detailed feasibility study should proceed. If the concept proves promising, later stages could involve pilot operations to test how hydrogen or battery traction performs in real‑world Scottish conditions, including challenging topography and weather.

Multi-energy hubs reimagine the role of the railway station

The second Ricardo-supported project focuses on railway stations and their potential to act as local energy hubs. Rather than viewing stations solely as points where passengers board and alight, the study investigates how they might host interconnected systems serving vehicles, buildings and the wider grid.

Project documentation describes an ambition to link electric vehicles in station car parks, on-site energy use within station buildings and adjacent facilities, and the traction power required for trains. By coordinating these elements, multi‑energy hubs could smooth peaks in demand, provide flexible capacity to support the electricity grid and open up new services for passengers and neighbouring communities.

The research considers how such hubs might be replicated at scale, with published information suggesting that the concept could eventually be applicable to thousands of stations across the UK network. Key questions include how to size local generation or storage assets, where to position charging infrastructure and how to manage energy flows to maximise efficiency while protecting rail operations.

If the concept progresses through further funding rounds, it could influence future station redevelopment schemes and the design of integrated mobility hubs that bring together rail, bus, micromobility and private vehicles, all supported by smarter energy management.

Partnerships highlight collaborative approach to rail decarbonisation

Publicly available information emphasises that Ricardo is working with a range of partners on the new research, including Scottish Power, Network Rail and the University of Leeds. This reflects a growing trend in transport decarbonisation projects, which increasingly draw together expertise from infrastructure owners, energy utilities, academia and specialist consultancies.

Energy innovation in the rail sector often sits at the intersection of several regulated industries, requiring coordination across technical, commercial and policy domains. Collaborations of this type allow railway-focused engineering teams to tap into utility experience with grid planning, while universities contribute modelling techniques and analytical capacity.

For the Strategic Innovation Fund, partnerships also provide a route to test how new concepts might fit into real-world operations. Involving infrastructure managers and power system operators at an early stage can highlight practical constraints, from network access windows to grid connection limits, that need to be addressed if a promising idea is to move beyond the laboratory.

The inclusion of academic partners suggests an additional focus on developing methodologies and tools that other organisations could adopt. Models produced through the studies may support future decision‑making by transport authorities, regulators and private operators considering investments in low‑carbon rail technologies.

Implications for future rail investment and passenger networks

While the Ricardo projects are at an early research stage, they point to several possible directions for future rail investment. If hydrogen or advanced battery traction proves competitive on rural lines, it could offer an alternative to full route electrification in areas where passenger numbers are modest and engineering works would be challenging.

Similarly, multi‑energy hubs at stations could change how planners think about transport corridors and local development. A station equipped with smart charging, storage and generation might serve as a neighbourhood energy centre, supporting both rail services and nearby homes or businesses, particularly in regions aiming to integrate more renewable power.

For travellers, many of the changes would be largely invisible, centred on how trains are powered and how electricity flows behind the scenes. Over time, however, successful deployment of new energy technologies could support quieter, cleaner rolling stock and more resilient services, especially during periods of high demand on national electricity networks.

Across Europe and beyond, rail is often highlighted as a backbone mode for low‑carbon mobility. Funding secured by Ricardo for rail‑related energy innovation adds to a growing portfolio of research efforts exploring how to align that role with evolving energy systems, with the outcomes likely to shape infrastructure priorities and technology choices well into the next decade.
