Solar-powered device captures carbon dioxide from air to make sustainable fuel

sc604 — Thu, 13 Feb 2025 10:00:00 +0000

̽��ֱ��researchers, from the ̽��ֱ�� of Cambridge, say their solar-powered reactor could be used to make fuel to power cars and planes, or the many chemicals and pharmaceuticals products we rely on. It could also be used to generate fuel in remote or off-grid locations.

Unlike most carbon capture technologies, the reactor developed by the Cambridge researchers does not require fossil-fuel-based power, or the transport and storage of carbon dioxide, but instead converts atmospheric CO2 into something useful using sunlight. ̽��ֱ��results are reported in the journal Nature Energy.

Carbon Capture and Storage (CCS) has been touted as a possible solution to the climate crisis, and has recently received £22bn in funding from the UK government. However, CCS is energy-intensive and there are concerns about the long-term safety of storing pressurised CO2 deep underground, although safety studies are currently being carried out.

“Aside from the expense and the energy intensity, CCS provides an excuse to carry on burning fossil fuels, which is what caused the climate crisis in the first place,” said Professor Erwin Reisner, who led the research. “CCS is also a non-circular process, since the pressurised CO2 is, at best, stored underground indefinitely, where it’s of no use to anyone.”

“What if instead of pumping the carbon dioxide underground, we made something useful from it?” said first author Dr Sayan Kar from Cambridge’s Yusuf Hamied Department of Chemistry. “CO2 is a harmful greenhouse gas, but it can also be turned into useful chemicals without contributing to global warming.”

̽��ֱ��focus of Reisner’s research group is the development of devices that convert waste, water and air into practical fuels and chemicals. These devices take their inspiration from photosynthesis: the process by which plants convert sunlight into food. ̽��ֱ��devices don’t use any outside power: no cables, no batteries – all they need is the power of the sun.

̽��ֱ��team’s newest system takes CO2 directly from the air and converts it into syngas: a key intermediate in the production of many chemicals and pharmaceuticals. ̽��ֱ��researchers say their approach, which does not require any transportation or storage, is much easier to scale up than earlier solar-powered devices.

̽��ֱ��device, a solar-powered flow reactor, uses specialised filters to grab CO2 from the air at night, like how a sponge soaks up water. When the sun comes out, the sunlight heats up the captured CO2, absorbing infrared radiation and a semiconductor powder absorbs the ultraviolet radiation to start a chemical reaction that converts the captured CO2 into solar syngas. A mirror on the reactor concentrates the sunlight, making the process more efficient.

̽��ֱ��researchers are currently working on converting the solar syngas into liquid fuels, which could be used to power cars, planes and more – without adding more CO2 to the atmosphere.

“If we made these devices at scale, they could solve two problems at once: removing CO2 from the atmosphere and creating a clean alternative to fossil fuels,” said Kar. “CO2 is seen as a harmful waste product, but it is also an opportunity.”

̽��ֱ��researchers say that a particularly promising opportunity is in the chemical and pharmaceutical sector, where syngas can be converted into many of the products we rely on every day, without contributing to climate change. They are building a larger scale version of the reactor and hope to begin tests in the spring.

If scaled up, the researchers say their reactor could be used in a decentralised way, so that individuals could theoretically generate their own fuel, which would be useful in remote or off-grid locations.

“Instead of continuing to dig up and burn fossil fuels to produce the products we have come to rely on, we can get all the CO2 we need directly from the air and reuse it,” said Reisner. “We can build a circular, sustainable economy – if we have the political will to do it.”

̽��ֱ��technology is being commercialised with the support of Cambridge Enterprise, the ̽��ֱ��’s commercialisation arm. ̽��ֱ��research was supported in part by UK Research and Innovation (UKRI), the European Research Council, the Royal Academy of Engineering, and the Cambridge Trust. Erwin Reisner is a Fellow of St John’s College, Cambridge.

Three Cambridge researchers awarded Royal Academy of Engineering Chair in Emerging Technologies

sc604 — Thu, 14 Mar 2024 11:06:52 +0000

From atomically thin semiconductors for more energy-efficient electronics, to harnessing the power of the sun by upcycling biomass and plastic waste into sustainable chemicals, their research encompasses a variety of technological advances with the potential to deliver wide-ranging benefits.

Funded by the UK Department for Science, Innovation and Technology, the Academy’s Chair in Emerging Technologies scheme aims to identify global research visionaries and provide them with long-term support. Each £2,500,000 award covers employment and research costs, enabling each researcher to focus on advancing their technology to application in a strategic manner for up to 10 years.

Since 2017, the Chair in Emerging Technologies programme has awarded over £100 million to Chairs in 16 universities located across the UK. Of the four Chairs awarded in this round, three were awarded to Cambridge researchers.

Professor Manish Chhowalla FREng, from the Department of Materials Science and Metallurgy, is developing ultra-low-power electronics based on wafer-scale manufacture of atomically thin (or 2D) semiconductors. ̽��ֱ��atomically thin nature of the 2D semiconductors makes them ideal for energy-efficient electronics. To reap their benefits, complementary metal oxide semiconductor processes will be developed for integration into ultra-low power devices.

Professor Nic Lane and his team at the Department of Computer Science and Technology, are working to make the development of AI more democratic by focusing on AI methods that are less centralised and more collaborative, and offer better privacy protection.

Their project, nicknamed DANTE, aims to encourage wider and more active participation across society in the development and adoption of AI techniques.

“Artificial intelligence (AI) is evolving towards a situation where only a handful of the largest companies in the world can participate,” said Lane. “Given the importance of this technology to society this trajectory must be changed. We aim to invent, popularise and commercialise core new scientific breakthroughs that will enable AI technology in the future to be far more collaborative, distributed and open than it is today.”

̽��ֱ��project will focus on developing decentralised forms of AI that facilitate the collaborative study, invention, development and deployment of machine learning products and methods, primarily between collections of companies and organisations. An underlying mission of DANTE is to facilitate advanced AI technology remaining available for adoption in the public sphere, for example in hospitals, public policy, and energy and transit infrastructure.

Professor Erwin Reisner, from the Yusuf Hamied Department of Chemistry, is developing a technology, called solar reforming, that creates sustainable fuels and chemicals from biomass and plastic waste. This solar-powered technology uses only waste, water and air as ingredients, and the sun powers a catalyst to produce green hydrogen fuel and platform chemicals to decarbonise the transport and chemical sectors. A recent review in Nature Reviews Chemistry gives an overview of plans for the technology.

“ ̽��ֱ��generous long-term support provided by the Royal Academy of Engineering will be the critical driver for our ambitions to engineer, scale and ultimately commercialise our solar chemical technology,” said Reisner. “ ̽��ֱ��timing for this support is perfect, as my team has recently demonstrated several prototypes for upcycling biomass and plastic waste using sunlight, and we have excellent momentum to grasp the opportunities arising from developing these new technologies. I also hope to use this Chair to leverage further support to establish a circular chemistry centre in Cambridge to tackle our biggest sustainability challenges.”

“I am excited to announce this latest round of Chairs in Emerging Technology,” said Dr Andrew Clark, Executive Director, Programmes, at the Royal Academy of Engineering. “ ̽��ֱ��mid-term reviews of the previous rounds of Chairs are providing encouraging evidence that long-term funding of this nature helps to bring the groundbreaking and influential ideas of visionary engineers to fruition. I look forward to seeing the impacts of these four exceptionally talented individuals.”

Three Cambridge researchers – Professors Manish Chhowalla, Nic Lane and Erwin Reisner – have each been awarded a Royal Academy of Engineering Chair in Emerging Technologies, to develop emerging technologies with high potential to deliver economic and social benefits to the UK.

Two Cambridge researchers awarded Royal Academy of Engineering Chair in Emerging Technologies

sc604 — Thu, 01 Dec 2022 16:02:01 +0000

Funded by the UK Department for Business, Energy and Industrial Strategy, the Chair in Emerging Technologies scheme aims to identify global research visionaries and provide them with long-term support. ̽��ֱ��awards will enable the researchers to focus on strategic approaches for taking their technology from the bench to the boardroom.

Professor Rachel Oliver, from the Department of Materials Science and Metallurgy, is a Fellow of Robinson College and Director of the Cambridge Centre for Gallium Nitride. Gallium nitride (GaN) is a rising star of the electronics and optoelectronics industries, with GaN-based solid-state lighting bringing about a revolution in how we illuminate our world. Creating porosity in GaN vastly extends the range of materials properties achievable in this key compound semiconductor material. By controlling the porosity, engineers can select the properties they need to create new device concepts or to improve existing products.

Professor Oliver's aim is to create a set of materials fabrication processes which control the structure and properties of porous gallium nitride. Alongside this, she will develop a modelling toolbox for designing new devices. By developing new devices and embedding porous GaN in the UK’s vibrant and expanding compound semiconductor industry, Oliver hopes to drive this emerging materials platform towards widespread industrial adoption, fuelling the future of the UK compound semiconductor ecosystem.

Potential applications for the new research are both wide-ranging and far-reaching. Developing the use of UV LEDs for disinfection would give healthcare professionals new weapons in the fight against viral epidemics and antibiotic-resistant bacteria. Work on microdisplays using microLEDs could improve augmented and virtual reality headsets. As well as providing immersive experiences for gamers, this technology could be used by organisations for more effective online collaboration. By reducing the need for business travel, the ecological benefits would be significant.

Professor Vignolini and her Bio-inspired Photonics group in the Yusuf Hamied Department of Chemistry have discovered that plants produce bright and vibrant colouration through organising cellulose into sub-micrometer structures that manipulate light. These natural examples have inspired Vignolini to mimic the use of biological building blocks to create sustainable colorants in the lab. She is developing a new generation of manufacturing processes to produce colours using only naturally derived biomaterials, such as cellulose, a biodegradable and abundant plant material.

Vignolini's vision is that bio-based pigments will replace current alternatives made with energy-intensive and problematic materials.

Professor Sir Jim McDonald FREng FRSE, President of the Royal Academy of Engineering, said: “ ̽��ֱ��Academy places huge importance on supporting excellence in engineering and often the key to engineers fulfilling their potential in tackling global challenges is the gift of time and continuity of support to bring the most disruptive and impactful ideas to fruition.”

Professor Rachel Oliver and Professor Silvia Vignolini from the ̽��ֱ�� of Cambridge have been awarded a Royal Academy of Engineering Chair in Emerging Technologies. Each award is worth £2.5 million over ten years to develop emerging technologies with high potential to deliver economic and social benefits to the UK.

Floating ‘artificial leaves’ ride the wave of clean fuel production

sc604 — Wed, 17 Aug 2022 14:58:44 +0000

Researchers have developed floating ‘artificial leaves’ that generate clean fuels from sunlight and water, and could eventually operate on a large scale at sea.

Cambridge researchers elected Fellows of the Royal Academy of Engineering

sc604 — Wed, 22 Sep 2021 05:00:00 +0000

Professors Holger Babinsky, Andrea Ferrari, Rob Miller and Rachel Oliver have been elected in this year’s intake, which consists of 60 Fellows, four International Fellows and five Honorary Fellows, with each individual having made exceptional contributions to their sectors in their own way, as innovation leaders, inspiring role models, or through remarkable achievements in business or academia.

Professor Holger Babinsky is Professor of Aerodynamics in the Department of Engineering and a Fellow of Magdalene College. He researches fundamental and applied aerodynamics with application to aeronautics, road vehicles and energy production.

“I am delighted to receive this remarkable honour and feel very lucky to be recognised by my peers for doing something I love,” said Babinsky. “I am also truly grateful to the ̽��ֱ��, the Engineering Department and all my colleagues and students for providing the environment and support that allowed me to grow as a researcher and educator.”

Professor Andrea Ferrari is Professor of Nanotechnology in the Department of Engineering. He is Director of the Cambridge Graphene Centre and of the EPSRC Centre for Doctoral Training in Graphene Technology, and a Fellow of Pembroke College.

I am pleased the Royal Academy of Engineering has recognised the translational potential of our work and I see this as a further encouragement to develop state of the art facilities that will lead to world-class research, technology and innovation.”

Professor Rob Miller is Professor of Aerothermal Technology in the Department of Engineering. He is Director of the Whittle Laboratory and a Fellow of Gonville and Caius College. Much of the research of the Whittle Laboratory is geared toward solving one of technology’s biggest puzzles: how to achieve zero-carbon flight.

“I am deeply grateful to all the colleagues and students that I have worked with, especially at the Whittle Laboratory and at Rolls-Royce, without whose support this would not have been possible,” said Miller. “Throughout my career I have benefited from working closely with industry. I believe that it is only through these partnerships, between industry and academia, that engineers can meet society’s greatest challenge, climate change.”

Professor Rachel Oliver is Professor of Materials Science in the Department of Materials Science and Metallurgy, Director of the Cambridge Centre for Gallium Nitride and a Fellow of Robinson College. When she’s not making atomic-scale changes to create super-efficient light bulbs and cut carbon emissions, she has her sights set on helping to improve equality and diversity in science.

“It’s fantastic that the Academy engages with everything from the nanoscale materials engineering, which is my focus, all the way up to the much grander scale of wind turbines and jet engines,” said Oliver. “All of these varied aspects of engineering are hugely important for sustainability, which is a big current focus for the Academy. I’m also looking forward to having the opportunity to engage with the work the Academy does to increase equity in the engineering profession, since I'm passionate about making fascinating and fulfilling careers in engineering accessible to the widest possible range of talented people.”

This year’s new Fellows are the first to reflect the Academy’s Fellowship Fit for the Future initiative announced in July 2020, to drive more nominations of outstanding engineers from underrepresented groups ahead of its 50th anniversary in 2026. This initiative will see the Academy strive for increased representation from women, disabled and LGBTQ+ engineers, those from minority ethnic backgrounds, non-traditional education pathways and emerging industries, and those who have achieved excellence at an earlier career stage than normal.

These new Fellows will be admitted to the Academy, which comprises nearly 1,700 distinguished engineers, at its AGM on 22 September. In joining the Fellowship, they will add their capabilities to the Academy’s mission to create a sustainable society and an inclusive economy for all.

Sir Jim McDonald FREng FRSE, President of the Royal Academy of Engineering, says: “Our Fellows represent the best of the best in the engineering world, and we welcome these 69 excellent and talented professionals to our community of businesspeople, entrepreneurs, innovators and academics.

“This year’s new Fellows are the most diverse group elected in the history of our institution. ̽��ֱ��engineering profession has long suffered from a diversity shortfall and the Academy is committed to changing that, including by ensuring that our own Fellowship community is as inclusive as it can be. It is well established that diverse organisations tend to be more agile and more innovative, and as the UK’s National Academy for engineering and technology, we have a responsibility to reflect the society we serve in addressing the shared challenges of our future.”

Cambridge engineers recognised with awards for pandemic service

sc604 — Mon, 17 Aug 2020 09:30:22 +0000

̽��ֱ��engineers, from the Institute of Manufacturing and the Whittle Laboratory, are among the 19 winners announced today for exceptional engineering achievements in tackling COVID-19 in the UK. In addition, two Cambridge alumni, Dr Ravi Solanki and Raymond Siems, were recognised for their work with the HEROES charity. In less than two days, their team turned an idea into a platform with genuine impact: a secure website through which more than 543,000 items of much-needed support have been provided to NHS workers, from sustainable PPE to counselling services and child care.

̽��ֱ��awards have been made to teams, organisations, individuals, collaborations and projects across all technical specialities, disciplines and career stages within the UK engineering community who have contributed to addressing the challenges of the COVID-19 pandemic.

Open Ventilator System Initiative

̽��ֱ��team behind the Open Ventilator System Initiative was recognised for their development of a high-performance ventilator for manufacture in low and middle-income countries that became the first intensive care quality ventilator to be manufactured in Africa.

In March 2020, as Covid-19 infection rates were rising dramatically in Europe, the number of infections in many low- and medium-income countries remained low. However, it was predicted that towards the summer these rates would start to increase. This was especially worrying due to the low number of ventilators available in the developing world.

In response to these fears, a team at the ̽��ֱ�� of Cambridge and a number of companies within the Cambridge cluster designed a high-performance intensive care ventilator for manufacture in low and middle-income countries. ̽��ֱ��aim was to develop a ventilator with a price point that was a factor of 10 lower than what was currently available, which could be manufactured from readily available components and which could be manufactured in-country. ̽��ֱ��result was the first clinical grade ventilator to be manufactured in Africa.

An engineering team led by Dr Tashiv Ramsander at Cambridge Aerothermal Ltd was quickly assembled at the Whittle Laboratory, and comprised people from several departments at the ̽��ֱ�� of Cambridge and a range of local companies including Cambridge Aerothermal, Beko R&D, Cambridge Instrumentation and Interneuron.

Together, this multidisciplinary team was able to solve problems such as the design of a pressure relief valve, inspired by the mixing nozzles on the Rolls-Royce Trent 1000 aircraft engine. ̽��ֱ��design removed flow instabilities, resulting in a more stable operation than any commercially available valve.

̽��ֱ��clinically driven design was developed with the help of two senior intensive care clinicians with experience of treating COVID-19. They argued that a design for developing countries needed to be more versatile than the UK government specification and the final design can operate in non-invasive, mandatory or patient-triggered ventilation modes.

For more than eight years the Whittle Laboratory has been developing a rapid technology development process for the aerospace and power generation sectors. During the pandemic this process was switched to develop a clinical grade ventilator within a week and allowing a rapid response to design changes driven by the pandemic, cost reduction and clinical demand.

̽��ֱ��final Open Ventilator design can be manufactured mostly from standard parts, anywhere in the world that it is needed.

̽��ֱ��reach and impact of COVID-19 in developing countries is not yet known, but this new design - the first intensive care quality ventilator to be manufactured in Africa - could prove to be a gamechanger when it comes to a host of conditions including pneumonia, as well as COVID-19. Childhood pneumonia killed 162,000 children in Nigeria alone in 2018.

There are very few ventilators in Africa, due to their high cost, inability to operate in harsh environments and a lack of local maintenance expertise. ̽��ֱ��team realised these problems could be solved by manufacturing the equipment in Africa. ̽��ֱ��Cambridge engineering team assembled a wider manufacturing team that includes Defy and Denel Land Systems in South Africa, Beko R&D and Prodrive in the UK and Arçelik in Turkey. This team delivered the first 20 preproduction ventilators in South Africa in June.

“ ̽��ֱ��result is a design that will save countless lives in the developing world where ventilators are scarce and many that exist cannot achieve the quality of performance that the Open Ventilator offers,” said Professor Richard Prager, head of the Department of Engineering. “It is a scalable solution. ̽��ֱ��high-performance open-source design will enable companies across the world to make systems wherever they are needed, and at a price that is compatible with the local healthcare systems.”

Institute for Manufacturing

̽��ֱ��IfM team helped local hospitals to make the best use of their resources, streamlining logistics for sourcing and storing vital PPE, informing decision-making on emergency demand, and developing a ventilator sharing system to be used in emergencies.

As hospitals scrambled to make the necessary operational changes needed to accommodate COVID-19 patients, a team of staff and students from the Institute for Manufacturing (IfM) at the ̽��ֱ�� of Cambridge was there to help. Working with clinicians and senior healthcare managers to assess the immediate and emerging operational challenges facing local hospitals, they identified where these could be addressed through the application of engineering capabilities and coordinated the roll-out of solutions.

̽��ֱ��IfM team addressed three groups of tasks between March and May in the areas of hospital logistics, personal protective equipment (PPE) delivery and intensive care unit (ICU) equipment development.

In the hospital logistics area, the team applied industrial engineering approaches to COVID-related challenges including modelling in-hospital patient flows, redesigning COVID-19 testing procedures and managing oxygen supplies to the wards.

Understanding oxygen flow through the local hospital involved examining pipes and their layout, then analysing usage by ventilator type and patient need, as well as modelling supply and demand. ̽��ֱ��in-depth work of the IfM team enabled the hospital’s clinical and estates teams to identify and address various bottlenecks and improve operational efficiency.

̽��ֱ��team also looked at the design, setup and management of a temporary logistics hub for coordinating the delivery of millions of items of donated PPE and assessed the production capabilities of local manufacturers to increase flexibility of PPE supplies for local hospitals.

In conjunction with anaesthetists at Royal Papworth Hospital, they also devised an active ventilator sharing system in case there were not enough ventilators available during the COVID-19 outbreak. This involved the accelerated design, prototyping and in-hospital testing of an active ventilator sharing system in just four weeks.

Duncan McFarlane, Professor of Industrial Information Engineering at the IfM, led the team as they engaged with senior clinical and management teams within local hospitals to understand their needs and implement effective and collaborative ways of working. This involved joining the hospital's regular operations planning meetings and running daily project reviews with key hospital personnel during the peak COVID-19 surge, as well as working directly with clinicians in areas such as COVID-19 test processes, ward oxygen supply, and equipment design.

̽��ֱ��IfM team helped local hospitals make the best use of their resources and streamlined logistics for sourcing and storing vital PPE and other issues, enabling healthcare providers who were already feeling the strain to address pressing operational challenges.

In addition, the IfM provided analytical approaches for informing decision making at Cambridge ̽��ֱ�� Hospital (CUH) on emergency demand. ̽��ֱ��Trust is also using the team’s findings to forecast changes to demand for beds, equipment and staff when social distancing measures are relaxed or modified further. ̽��ֱ��hospital said the engineers brought diversity of perspective and a joint CUH–IfM panel has been initiated so that the hospitals and the IfM can continue working together for mutual benefit after the pandemic.

“ ̽��ֱ��team gave key support efficiently and skilfully when it was most needed, with no fuss and maximum impact: engineering at its best,” said Professor Prager. “ ̽��ֱ��team found a way to work with the clinicians without taking up too much clinical time. They found the problems that needed solving and got on with solving them. They stepped up when they were needed and made a real difference. For this, we should be proud of them.”

Professor Tim Minshall, Dr John C Taylor Professor of Innovation and Head of the Institute for Manufacturing, said: “It makes me so proud to see the way in which our students and staff – academic, research and administrative – were able to rapidly understand and help address the operational challenges facing the amazing teams at Addenbrooke’s and Royal Papworth during this crisis.

“We are also delighted that there is such enthusiasm from both CUH and the IfM to build upon this experience and to develop ongoing collaboration in applying industrial engineering capabilities to healthcare system needs.”

‘Blitz spirit’ needed to adapt to climate change, engineer warns

sc604 — Tue, 03 Nov 2015 16:39:25 +0000

Giving the Academy's Autumn Lecture on Tuesday 3 November, Dr Hunt will compare today's challenge of adapting to future climate change with the imperative to develop new technologies to tip the balance of military capability in favour of the Allies during World War 2. Necessity fuelled many technological developments during the 1939-45 period that decisively influenced the course of WW2, including radar, the Enigma machine and the jet engine.

However, it is the sheer scope of Barnes Wallis's lateral thinking in developing the bouncing bomb that fascinates Dr Hunt and epitomises the approach he thinks is now required from modern engineers in responding to climate change. Despite Bomber Command's belief in the effectiveness of area bombing, Wallis saw it as a very blunt instrument and managed to persuade "Bomber" Harris to consider his idea of blowing up key German dams in order to cripple the steel industry.

“Barnes Wallis responded to the emergency of his time with extreme lateral thinking,” said Dr Hunt, “and we need that mentality again now if we are to move towards low carbon energy and provide clean water and food for the world's population. These are the great challenges of our time and we need to look at much bolder solutions, like designing structures to have multiple functions.

“Flood defences are a great example of where this might help - you can use them to generate tidal power when they are not needed to prevent flooding. Perhaps such a scheme at the mouth of the River Parrott could be used both to generate power and to protect the Somerset Levels from flooding.

“Personally, I think we may actually be too late to mitigate the worst effects of climate change and that we also need to be looking at truly radical geoengineering schemes like re-freezing the polar ice caps. ̽��ֱ��fact that it sounds completely mad would not have put Barnes Wallis off, and we need more of his kind of unrestrained imagination coupled with technological genius.”

Adapted from a Royal Academy of Engineering press release.

Today's engineers will need the kind of drive and determination shown by the great wartime innovators such as Sir Barnes Wallis and Sir Frank Whittle if they are to respond effectively to climate change, ̽��ֱ�� of Cambridge Reader in Engineering Dr Hugh Hunt will tell the Royal Academy of Engineering.
