A team of scientists from the University of Nottingham’s School of Chemistry and Faculty of Engineering have found a way to facilitate sustainable hydrogen production from metal waste.
In new research, the team found that the surface of swarf, a byproduct of the metal machinery industry, is textured with tiny grooves and steps on a nanoscale level.
These textures can anchor atoms of platinum or cobalt. This leads to an efficient electrocatalyst that can make hydrogen more sustainable by splitting water into hydrogen and oxygen.
Electrolysis is a promising pathway for hydrogen production
Hydrogen is a clean fuel that can be used to generate heat or power vehicles.
The only byproduct of its combustion is water vapour.
However, most hydrogen production methods require fossil fuel feedstock.
Electrolysis of water is one of the most promising methods for hydrogen production because it only needs water and electricity.
The challenge with water electrolysis
The industry is facing a challenge with water electrolysis. This is because it requires expensive elements like platinum to catalyse the water splitting.
As demand rises and prices increase, there is an urgent need for alternative electrocatalyst materials to produce hydrogen from water.
Dr Jesum Alves Fernandes from the School of Chemistry, University of Nottingham, who led the research team, said: “Industries in the UK alone generate millions of tonnes of metal waste annually. By using a scanning electron microscope, we were able to inspect the seemingly smooth surfaces of the stainless steel, titanium, or nickel alloy swarf.
“To our astonishment, we discovered that the surfaces had grooves and ridges that were only tens of nanometres wide. We realised that this nanotextured surface could present a unique opportunity for the fabrication of electrocatalysts.”
Scaling up the technology
The team used magnetron sputtering to create a platinum atom rain on the swarf’s surface. The atoms come together into nanoparticles that fit into the nanoscale grooves.
Professor Andrei Khlobystov, School of Chemistry, said: “Our unique technology developed at Nottingham, which involves atom-by-atom growth of platinum particles on nanotextured surfaces, has solved two major challenges.
“Firstly, it enables the production of green hydrogen using the least amount of precious metal possible, and secondly, it upcycles metal waste from the aerospace industry, all in a single process.”
The group will partner with AqSorption Ltd, a Nottingham-based company specialising in electrolyser design and fabrication, to scale up their technology.
The new work represents a step forward in reducing reliance on expensive metals for hydrogen production.
EasyJet has successfully completed the UK’s first airside hydrogen refuelling trial at Bristol Airport.
The hydrogen refuelling trial, known as Project Acorn, tested the performance of hydrogen fuel in powering ground support equipment (GSE), specifically baggage tractors.
The trial involved an array of cross-industry partners, including Cranfield Aerospace Solutions, Cranfield University, Connected Places Catapult (CPC), DHL Supply Chain, Fuel Cell Systems, the IAAPS research institute, Jacobs, Mulag and TCR.
Project Acorn demonstrated that hydrogen refuelling could be used safely and reliably to power GSE in the busy environment of a live airport.
The team will utilise the findings of the trial to supplement research groups, such as Hydrogen in Aviation (HIA), to advance UK hydrogen infrastructure and develop regulatory and policy guidelines for airports, airlines, local authorities, and regulators.
The goal is to support the development of a regulatory framework for hydrogen’s use on an airfield, as due to the nascency of hydrogen in aviation, these do not currently exist.
Tim Johnson, Director for Strategy, Policy and Communications at the Civil Aviation Authority, explained the significance of the trial: “Projects such as this are cornerstones of our commitment to support innovation and decarbonisation in the industry.
“This trial will serve as the basis of a White Paper which we will also be contributing to, as well as allow for the creation of further safety guidance and regulatory standards for the use of hydrogen in aviation.
“We look forward to helping nurture this seed of the future greener aviation sector as it continues to grow.”
Benefits of hydrogen in aviation for the UK
Experts emphasise that hydrogen-powered aviation is crucial for achieving net zero emissions and offers significant economic benefits.
According to the Jet Zero Strategy, investing in hydrogen aviation could create over 60,000 jobs in the UK and contribute £18bn to the economy by 2050.
Green hydrogen, produced sustainably, emits no carbon and is pivotal for the industry’s decarbonisation.
The Jet Zero Council projects that such investment could secure up to 19% of the global aerospace industry by 2050, adding £34bn annually to the UK economy.
This investment not only addresses environmental concerns but also maintains the societal benefits of air travel.
David Morgan, Chief Operating Officer at easyJet, added: “It’s without doubt that hydrogen will be an important fuel of the future for short-haul aviation, as demonstrated by the rate of innovation we’re seeing.
“While the technology is advancing at an exciting pace, as hydrogen isn’t used in commercial aviation today, there is currently no regulatory guidance in place on how it can and should be used, and so trials like this are very important in building the safety case and providing critical data and insight to inform the development of the industry’s first regulatory framework.
“This will ensure regulation not only keeps pace with innovation, but importantly also supports the industry in meeting its decarbonisation targets by 2050.”
Outcomes of Project Acorn
The UK aviation industry faces a tight deadline to prepare its ground infrastructure, safety standards, and operational procedures for hydrogen use.
Project Acorn serves as an initial step towards this goal, conducting trials of GSE to gain Civil Aviation Authority (CAA) approval for airside hydrogen refuelling.
These trials, conducted with CAA oversight, also involve safety assessments and emergency planning with local authorities at Bristol Airport, providing vital insights for future hydrogen transitions at other airports.
The project paves the way for long-term hydrogen GSE deployment at Bristol Airport and prepares for trials and commercial operations of hydrogen-fuelled aircraft.
Despite hydrogen’s potential as a zero-emission fuel, significant regulatory and safety challenges persist.
The trial of gaseous hydrogen-fuelled GSE at Bristol Airport marks a key milestone, offering insights crucial for informing hydrogen infrastructure policy and safe handling in airport operations.
Ultimately, this research aims to support wider aviation decarbonisation by facilitating the rapid uptake of hydrogen.
The European Commission has announced it will fund €424m to advance the EU’s alternative fuel infrastructure.
Optimising Europe’s alternative fuel supply will be essential for supporting the uptake of electric and hydrogen vehicles.
The funding will support 42 projects across the alternative fuel supply chain, which have been selected under the Alternative Fuels Infrastructure Facility (AFIF) of the Connecting Europe Facility (CEF), the EU funding programme supporting European transport infrastructure.
Director of the European Climate, Infrastructure and Environment Executive Agency (CINEA), Paloma Aba Garrote, commented on the funding: “We continue to support projects of paramount importance to the realisation of the objectives laid out under the EU Green Deal.
“With this new selection, the European Union is showing that a transition to zero-emission transport through alternative fuels is not a dream for the future, but something that is happening now across the EU.”
Supporting Europe’s zero-emission mobility
The aim of the Connecting Europe Facility Alternative Fuels Infrastructure Facility call for proposals is to assist in the expansion of alternative fuel supply infrastructure, thereby aiding in the reduction of carbon emissions in transportation across the European TEN-T network.
With a total budget of €1bn allocated for the period of 2024-2025, AFIF finances projects by leveraging CEF grants and support from financial institutions.
This initiative operates through a rolling call for proposals initiated on 29 February 2024, with three deadlines for proposal submissions until the conclusion of 2025.
Advancing alternative fuel infrastructure
The funding will be employed to develop 4,200 EV charging points throughout the TEN-T road network.
Additionally, 48 hydrogen refuelling stations will be created for cars, trucks, and buses, with the electrification of ground handling services in 21 airports also targeted.
European Commissioner for Transport Adina Vălean, added: “Since 2021, the EU has granted over €1.3bn through AFIF to several projects, deploying 26,396 electric recharging points, 202 hydrogen refuelling stations, and electrifying ground operations in 63 airports.
“This last call was the most successful regarding the projects’ number and quality so far, showing the growing interest in hydrogen and electric charging infrastructure.”
Hygen has announced it has been granted planning permissions to develop a major low-carbon hydrogen production facility in the UK.
The state-of-the-art hydrogen production facility will be located in Bradford and will be one of the largest hubs for producing hydrogen nationwide.
Hygen is collaborating with N-Gen to deliver the hydrogen production facility, which promises to generate enough hydrogen fuel to significantly decarbonise transport and industry.
Jamie Burns, Director at Hygen, commented on the development: “The granting of planning permission is a significant step in the development of a facility which will provide enormous benefits to the people of Bradford and the surrounding area.
“Along with our partners, we have worked tirelessly to develop these plans, which will provide a blueprint for how complex projects like this can be delivered, boosting the hydrogen and green economies of the UK.”
Building the UK hydrogen economy
Hydrogen serves as a versatile fuel capable of substituting natural gas in heating and industrial operations, as well as replacing diesel in heavy-duty vehicles such as buses, trains, and trucks.
What’s more, hydrogen produces no carbon when burned, making it the ideal energy source as the UK strives to battle climate change.
The UK Government recognises this potential and has recently announced major funding to develop the UK’s hydrogen industry.
The government has now backed the Bradford hydrogen production facility, making it the biggest scheme to be awarded funding through the government’s Hydrogen Production Business Model.
Overview of the hydrogen production facility
Following planning approval from Bradford Council, the clean hydrogen hub will be situated on the old Birkshall gas storage site on Bowling Back Lane.
The production of hydrogen will occur via electrolysis, a process utilising renewable electricity to separate water into hydrogen and oxygen components.
Once operational, the hydrogen production facility will generate around 12.5 tonnes of hydrogen per day.
Hygen aims to produce enough hydrogen to replace 800 diesel-fuelled buses with hydrogen buses emitting zero emissions, operating on the roads of West Yorkshire daily.
Benefits to the local area
Businesses and other stakeholders in West Yorkshire will have access to on-site refuelling facilities, while distribution specialists Ryze will deliver hydrogen to industrial users throughout the region.
Gareth Mills, Managing Director at N-Gen, added: “We are extremely proud to be bringing a flagship hydrogen production facility and significant investment to Bradford.
“The site was once home to gas holders, which stored natural gas used by the residents and businesses in Bradford, so it is fitting that the site will continue its heritage and now be used for the production and storage of hydrogen, a cleaner fuel.
“We expect the facility to be a valuable addition to the Bradford economy, providing a viable way for local businesses to decarbonise, as well as attracting new companies and jobs to the area by placing the city at the forefront of the transition to clean energy.”
The UK Government has announced plans to introduce hydrogen vehicles in the agriculture and construction industries.
In a consultation launched today, the government has detailed new regulations that will see hydrogen vehicles, such as tractors, diggers, and forklifts, rolled out to help these sectors go greener.
Agriculture and construction produce significant carbon emissions. Hydrogen vehicles can significantly help decarbonise industries that are critical to the UK economy.
The new regulations will allow hydrogen-powered tractors, diggers, and forklifts to be used on UK roads, with the consultation running for four weeks, closing on 24 April.
Anthony Browne, the UK’s Technology and Decarbonisation Minister, explained the importance of the move: “Allowing hydrogen-powered tractors, diggers and forklifts to use our roads is a common-sense move to help reduce emissions.
“These proposals are an important part of our plan to decarbonise transport in the UK, with skilled jobs in British companies helping roll out this cutting-edge hydrogen technology, making it more affordable and commonplace.”
Benefits of hydrogen vehicles
The rumble of tractors and digger excavators are vital sounds in agriculture and construction, but they also contribute significantly to greenhouse gas emissions.
Hydrogen fuel cell technology offers a promising solution, bringing a wave of environmental and operational benefits to these crucial industries.
Unlike traditional diesel or petrol engines, hydrogen vehicles produce zero tailpipe emissions. This translates to cleaner air on farms and construction sites, improving the health of workers and surrounding communities. Additionally, it helps combat climate change by reducing greenhouse gas footprints.
Hydrogen fuel cells operate quietly compared to combustion engines. This creates a calmer work environment for operators and reduces noise pollution for nearby residents and wildlife. This can be particularly advantageous in noise-sensitive areas or during night time operations.
Modern hydrogen fuel cells offer a range comparable to traditional diesel vehicles, allowing farmers and construction crews to work a full shift without needing to refuel. Refuelling times are also projected to be similar to diesel or gasoline, minimising downtime.
Hydrogen vehicles also deliver high torque and power, which is ideal for the demanding tasks encountered in farming and construction. Whether it’s pulling heavy loads, operating hydraulic machinery, or navigating uneven terrain, hydrogen vehicles can provide the muscle needed for the job.
Hydrogen fuel production can be linked to renewable energy sources like solar or wind power, creating a truly sustainable transportation cycle. This aligns with the growing focus on eco-friendly practices in both agriculture and construction.
UK commitment to hydrogen infrastructure
The consultation launch follows the government’s authorisation of construction equipment manufacturer JCB with a special order last year, allowing the testing of hydrogen-powered diggers on UK roads.
The current proposals aim to extend this permission indefinitely throughout the sector, enabling manufacturers to efficiently increase the production of sustainable equipment, particularly where battery electric power is not feasible.
Hydrogen, alongside electric power, stands out as one of the numerous sustainable fuel options capable of expediting decarbonisation efforts.
Initiatives like the government-backed Tees Valley Hydrogen Hub demonstrate the practical utilisation of green hydrogen across the transportation sector, fostering job creation, apprenticeships, and economic growth in the region.

Researchers have successfully transformed CO2 into methanol by shining sunlight on single atoms of copper deposited on a light-activated material, a discovery that paves the way for creating new green fuels.
An international team of researchers from the University of Nottingham’s School of Chemistry, University of Birmingham, University of Queensland, and University of Ulm have designed a material, made up of copper anchored on nanocrystalline carbon nitride. The copper atoms are nested within the nanocrystalline structure, which allows electrons to move from carbon nitride to CO2, an essential step in the production of methanol from CO2 under the influence of solar irradiation. The research has been published in the Sustainable Energy & Fuels journal of the Royal Society of Chemistry.
The Challenge of Efficiency and Selectivity
In photocatalysis, light is shone on a semiconductor material that excites electrons, enabling them to travel through the material to react with CO2 and water, leading to a variety of useful products, including methanol, which is a green fuel. Despite recent progress, this process suffers from a lack of efficiency and selectivity.
Carbon dioxide is the greatest contributor to global warming. Although, it is possible to convert CO2 to useful products, traditional thermal methods rely on hydrogen sourced from fossil fuels. It is important to develop alternative methods based on photo- and electrocatalysis, taking advantage of the sustainable solar energy and abundance of omnipresent water.
Nanoscale Control for Improved Catalysis
Dr Madasamy Thangamuthu, a research fellow in the School of Chemistry, University of Nottingham, who co-led the research team, said: “There is a large variety of different materials used in photocatalysis. It is important that the photocatalyst absorbs light and separates charge carriers with high efficiency. In our approach, we control the material at the nanoscale. We developed a new form of carbon nitride with crystalline nanoscale domains that allow efficient interaction with light as well as sufficient charge separation.”

The researchers devised a process of heating carbon nitride to the required degree of crystallinity, maximizing the functional properties of this material for photocatalysis. Using magnetron sputtering, they deposited atomic copper in a solventless process, allowing intimate contact between the semiconductor and metal atoms.
Surprising Efficiency Gains
Tara LeMercier, a PhD student who carried out the experimental work at the University of Nottingham, School of Chemistry, said: “We measured the current generated by light and used it as a criterion to judge the quality of the catalyst. Even without copper, the new form of carbon nitride is 44 times more active than traditional carbon nitride. However, to our surprise, the addition of only 1 mg of copper per 1 g of carbon nitride quadrupled this efficiency. Most importantly the selectivity changed from methane, another greenhouse gas, to methanol, a valuable green fuel.”
Professor Andrei Khlobystov, School of Chemistry, University of Nottingham, said: “Carbon dioxide valorization holds the key for achieving the net-zero ambition of the UK. It is vitally important to ensure the sustainability of our catalyst materials for this important reaction. A big advantage of the new catalyst is that it consists of sustainable elements – carbon, nitrogen, and copper – all highly abundant on our planet.”
This invention represents a significant step towards a deep understanding of photocatalytic materials in CO2 conversion. It opens a pathway for creating highly selective and tuneable catalysts where the desired product could be dialed up by controlling the catalyst at the nanoscale.

Regulatory compliance is also a significant aspect of this process. With the growing interest in hydrogen as a fuel, governments worldwide are updating and establishing regulations to ensure safety, encourage innovation, and promote the use of hydrogen.
Hydrogen refuelling challenges and solutions
Despite hydrogen’s promising potential as a sustainable fuel, numerous challenges persist in hydrogen refuelling, necessitating the exploration of innovative solutions.
One such issue is temperature management during the refuelling process. The high pressures involved in hydrogen refuelling create a tremendous amount of heat, which can lead to safety hazards and mechanical failures. Control strategies, such as advanced cooling systems and pressure regulation mechanisms, are being developed to manage these temperatures.
Refuelling protocols also present challenges, as differing standards across regions can lead to inefficiencies and compatibility issues. A global, standardised approach to hydrogen refuelling would streamline processes and make hydrogen vehicles more accessible.
Research into this area is ongoing, focusing on safety, reliability, and refuelling speed.
Emissions analysis is another crucial aspect of the hydrogen refuelling process. While hydrogen fuel produces zero tailpipe emissions, the production and refuelling processes can still lead to greenhouse gas emissions, depending on the source of the hydrogen and the energy used in the process.
New technologies and strategies are being explored to minimise these emissions and make hydrogen refuelling genuinely sustainable.
Mobile hydrogen refuelling developments
Building on the challenges and solutions in the hydrogen refuelling process, the concept of mobile hydrogen refuelling presents a significant development in this domain. It aims to overcome infrastructural limitations and increase accessibility.
This revolutionary approach offers portable solutions, enhancing refuelling efficiency and enabling ‘on the go’ refuelling for hydrogen-powered vehicles.
The introduction of mobile refuelling stations provides an innovative response to the lack of permanent hydrogen refuelling infrastructure, particularly in remote or rural areas. These temporary stations are designed for rapid deployment and easy dismantling, making them a practical solution for immediate refuelling needs.
They can be strategically located where demand is highest, providing a flexible and adaptable refuelling system.
The use of mobile refuelling units also significantly reduces the initial investment required to establish a hydrogen refuelling infrastructure, making it a financially viable option for regions in the early stages of transitioning to hydrogen-powered transportation.
Efficiency is another key advantage of mobile hydrogen refuelling. The process is quicker and more streamlined, minimising vehicle downtime. This is particularly beneficial for commercial vehicles, where any delay can have significant financial implications.
Hydrogen’s role in carbon-free transport
Undeniably, hydrogen is a pivotal player in the move towards carbon-free transport. It offers immense potential for reducing greenhouse gas emissions in the transportation sector.
As we strive for environmental benefits and energy efficiency, hydrogen provides a path to sustainable solutions that can seamlessly integrate into our current vehicle systems.
Hydrogen fuel cells, with their carbon-free applications, can be a key part of our transition to a sustainable transportation future. These cells convert hydrogen and oxygen into electricity, with water as the only by-product.
This makes them a highly attractive option for vehicle integration, as they have the potential to drastically reduce our reliance on fossil fuels.
Hydrogen’s role in carbon-free transport is not without challenges. The infrastructure for hydrogen refuelling stations is still in its early stages, and public awareness and acceptance of hydrogen vehicles need to be improved.
However, with suitable investment and policy support, hydrogen has the potential to revolutionise the transport sector. It provides a sustainable solution that benefits not only the environment but also the economy.
Infrastructure needs for hydrogen vehicles
Infrastructure challenges must be addressed with sustainable solutions to foster the development of a carbon-free transportation landscape.
Fuelling stations are a critical component of this infrastructure. However, hydrogen fuelling stations are considerably sparse, presenting a significant hurdle to the broader acceptance and use of hydrogen vehicles.
There is a clear need to scale up the deployment of these stations, particularly in urban areas where the demand for hydrogen vehicles is likely to be highest. However, urban hydrogen fuelling station deployment comes with its own set of challenges, including space constraints and safety considerations.
Grid integration is another vital aspect of the infrastructure needed for hydrogen vehicles. Power grids will need to accommodate the increased load from hydrogen production facilities. Advanced grid management strategies may be needed to ensure the stability of power networks and minimise disruptions.
Moreover, the entire hydrogen supply chain needs to be developed, from production to delivery. This includes constructing pipelines and storage facilities and the development of technologies for efficient and safe hydrogen transport.
Future directions in hydrogen fuel cell technology
As we navigate the complexities of our current energy landscape, the potential future of hydrogen technology is taking shape, with promising advancements and innovations on the horizon.
These advancements are driven not only by research opportunities but also by market trends and policy implications. The emergence of hydrogen as a key player in sustainable transportation is increasingly gaining momentum, opening up numerous investment prospects.
Despite the promising future, technological barriers must be addressed to harness the potential of hydrogen technology fully. These include challenges related to the production, storage, and transportation of hydrogen, which currently pose significant hurdles in the widespread adoption of this technology.
Furthermore, policy implications should be considered as they can help shape the direction of hydrogen technology. Policymakers have a crucial role in setting the right regulatory frameworks to foster hydrogen technology development and deployment.
As we move forward, it is crucial to continue exploring these aspects in depth while embracing the opportunities and addressing the barriers that arise.
This will be key to unlocking the full potential of hydrogen technology in sustainable transportation.
