The NHS programme called “Healthy Living for people with type 2 diabetes” is a website containing written articles, videos, self-assessment quizzes and tools.

It supports people to live well with T2D by providing information and advice about eating well, becoming more active, living with diabetes, and emotional wellbeing.

Published today in PLOS One, the study is funded by the National Institute for Health and Care Research (NIHR).

The research team analysed data from people with T2D who activated a Healthy Living account and found they experienced better health outcomes at one year than those who did not take part.

They examined who was most likely to use the programme (uptake) and how engagement related to changes in HbA1c – a blood test used to measure average blood sugar levels - blood pressure, body mass index, insulin use, and completion of essential diabetes care processes.

The findings show, uptake of the programme was highest among women, people from least deprived areas (vs. most deprived areas), and people of White ethnicity, and current smokers (vs. never smokers).

To assess clinical outcomes, the study compared 4,940 Healthy Living users with 24,685 similar individuals who did not register for the programme. After a year, Healthy Living users saw an average HbA1c drop of 1.3 mmol/mol, alongside small but steady dips in BMI and blood pressure, all pointing to better day‑to‑day control of their diabetes.

They were also 1.6 times more likely to complete the routine yearly MOT that helps spot problems early, keeping on top of the vital checks that protect the eyes, feet, heart and kidneys in the long run.

However, the study highlights that even small average improvements can translate into meaningful reductions in T2D‑related complications when applied across large populations.

It also underscores the need to address inequalities in uptake, with notably lower participation among Asian and Black communities despite higher T2D prevalence.

Lead author Dr said: “What this study shows, in the plainest possible terms, is that a free, nationally available NHS educational programme can help people with T2D make measurable improvements to their health, even when used in the complex reality of everyday life.

“It’s not a silver bullet, but it is a practical tool that works – and the challenge now is ensuring that everyone who could benefit has the opportunity to do so.”

“We feel Healthy Living offers a scalable, accessible option for supporting type 2 diabetes self‑management, particularly for people who face barriers to attending in‑person diabetes education programmes.

“Improving uptake among underserved groups will be essential to ensuring the programme reduces existing health inequalities.”

Co-author , Principal Investigator and an Honorary Reader at The University of Manchester said: “People’s outcomes were better for those who attended more of the Healthy Living programme, so it would be worthwhile for the NHS to find ways to encourage people to attend for longer, such as improved signposting and motivational messages”

• The paper Examining the uptake, retention, and effectiveness of a national online type 2 2 diabetes self-management intervention in England (Healthy Living): a retrospective 3 cohort study is available DOI

“More young people are reporting good wellbeing, loneliness is falling and emotional difficulties are reducing – which are encouraging findings – but the picture is not the same for everyone. Significant inequalities remain, particularly for LGBTQ+ young people and those with special educational needs, and that remains a major challenge.”

Measuring around a metre in length and armed with pincers over 16 centimetres long, Praearcturus gigas would have been a formidable predator stalking floodplains around 415 million years ago. Remarkably, the fossils used to identify Praearcturus have been held in the Museum’s collection for more than 150 years.

The study, published in the journal, used modern analytical techniques and comparisons with newly described fossil species to suggest that Praearcturus is a scorpion, and a distinct species.

Dr Richard J. Howard, Curator of Fossil Arthropods at the Natural History Museum, London, and lead author of the study, said: “When we think of giant arthropods, people often picture Carboniferous rainforests with giant millipedes or dragonfly-like insects from later in Earth’s history. But Praearcturus lived at least 50 million years earlier, well before the evolution of trees, when life on land was only just getting started.

“Confirming that this animal is a scorpion fundamentally changes our understanding of how and when these creatures evolved to such extraordinary sizes.”

, Palaeontologist at The University of Manchester, added: “Praearcturus has puzzled us palaeontologists for more than a century. By bringing together material from several collections and using cutting edge imaging techniques , we've been able to build a clearer picture of the animal than was previously possible, which is really exciting.

“What makes Praearcturus so interesting is that it became enormous at a time when life on land was otherwise very small. But it was a world  that could somehow support a giant predator. To try and better understand this ancient world we compared the size of fossil scorpions with other animals alive at the time. To reach such extraordinary sizes, and conclude that perhaps it lived in water, where life was bigger.”

Praearcturus gigas lived during the Early Devonian. Small plants and fungi had only recently begun to spread across the landscape, and complex terrestrial ecosystems like forests had yet to evolve. This means that, unlike later giant arthropods, Praearcturus did not benefit from the high atmospheric oxygen levels associated with the rise of forests. Instead, its enormous size may reflect a world with relatively little competition from other large predators. This suggests that Praearcturus might have grown so big simply because there weren’t many other large animals around meaning it could dominate its environment in a way that wouldn’t be possible later on.

The fossils also hint that this giant scorpion may have led a partly aquatic lifestyle. Some specimens show flap-like structures on the abdomen similar to those found in modern crustaceans such as lobsters, suggesting it may have been capable of moving between water and land. Quantification of the wider arachnid fossil record, led by Dr Garwood and the team, shows that scorpions are unusually abundant in rocks of this age compared with other arachnids, supporting the idea that some early forms may have lived in freshwater environments where they are more likely to survive as fossils. This places Praearcturus at a pivotal moment in Earth’s history when animals were first experimenting with life outside the oceans.

 This places Praearcturus at a pivotal moment in Earth’s history when animals were first experimenting with life outside the oceans.

Dr Greg Edgecombe, Merit Researcher at the Natural History Musuem, London, and co-author of the study said: “The boundary between land and sea was much less defined at this time. Praearcturus gives us a fascinating glimpse into how early animals adapted to these changing environments.

“It may even represent a lineage that returned to the water after earlier ancestors had already begun living on land.”

First described in 1871, Praearcturus gigas was originally thought to be a giant crustacean, similar to a woodlouse. The known fossils fragmentary nature lacked key features such as a tail making it difficult to classify with confidence for more than a century.

The breakthrough came through comparison with better preserved fossils discovered in recent years, which revealed key anatomical features unique to scorpions. The discovery highlights the continuing scientific importance of museum collections.

Dr Howard added: “Specimens collected over a century ago can still hold entirely new insights. By revisiting them with modern techniques, we can uncover discoveries that reshape our understanding of life on Earth.”

The discovery of such a large scorpion so early in the history of life on land challenges assumptions about why prehistoric arthropods reached gigantic sizes. Rather than being driven solely by environmental factors such as oxygen levels, the findings suggest that ecological opportunity such as a lack of competition may have played a crucial role.

The findings show that virtual wards can provide a safe alternative to hospital care for some patients, allowing people to recover at home while still receiving clinical oversight. However, patients and carers often take on more practical and emotional responsibility than may be recognised as they assume duties that would normally be carried out by clinicians in hospital settings. This includes monitoring symptoms, managing equipment and responding to signs of deterioration, especially overnight or outside normal working hours.

The study, published in the journal and led by researchers at The University of Manchester, is funded by the NIHR Greater Manchester Patient Safety Research Collaboration (GM PSRC) and the NIHR Applied Research Collaboration Greater Manchester (ARC-GM).

Using qualitative methods, including observation work and interviews with patients and carers, the researchers evaluated virtual wards services across four sites in North-West England. Their findings show that safety in virtual wards does not rely on technology alone, but is strongly shaped by the relational and emotional support provided to patients, carers and clinicians.

Dr Kelly Howells, Research Fellow at The University of Manchester and the NIHR GM PSRC, said: “Virtual wards can help people receive acute care safely at home, but our study shows safe care depends on more than technology.

“Patients, carers and clinicians all play a role in managing risk, with patients and carers often taking on important practical and emotional responsibilities, particularly outside normal working hours. Health services need to recognise and better support this work.”

The researchers suggest that hospital at home services that combine technology with in‑person home visits could help make care safer, more flexible, and accessible for a wider range of patients. Recognising and supporting the work undertaken by patients and carers is essential to ensure virtual wards are safely delivered.

As virtual wards expand as a key component of NHS policy to shift acute care from hospital to community settings, practice must ensure there is space for relational and training support for clinicians, patients, and carers so that remote acute care can be safely implemented across health systems.

This study builds on earlier work by the NIHR GM PSRC and ARC-GM exploring virtual wards through the perspectives of patients, carers and staff, helping to deepen understanding of how virtual ward services operate in practice.

Colgate-Palmolive, a caring, innovative growth company that is reimagining a healthier future for all people, their pets and our planet, will continue to fund the renowned Dental Health Unit (DHU) at the University.

Selling its health and hygiene products in more than 200 countries and territories, Colgate-Palmolive is the global leader in toothpaste and manual toothbrushes. With historic links to Manchester, the company’s former Colgate-Palmolive factory in Salford Quays, built in 1938, was redeveloped in 2005 into the famous landmark now known as Soapworks.

The global leader in oral health has been working with The University of Manchester since 1968, amounting to the University’s longest ever business partnership. The DHU has been a leading centre for oral health research for almost 60 years.

Initially carrying out clinical trials to evaluate the efficacy of Colgate products in collaboration with Colgate’s Research & Development team, the DHU has quickly evolved into a public health-focused program working collaboratively to mentor PhD candidates and to develop leaders in dentistry throughout the UK and beyond.

The extension of the funding will support high-quality clinical and behavioural research to generate real-world evidence for policy and practice. It will also allow the DHU to run a Fellowship Program – training the next generation of oral health researchers. The first awards to train future leaders have been announced with funding available for early career researchers in Europe and North America.

Anne-Marie Glenny, Professor of Health Sciences and Associate Dean for Research and Innovation at the School of Medical Sciences, said: “For over 50 years, the Dental Health Unit and our proud, historic association with Colgate Palmolive has reaped real health impacts, carrying out world -leading oral health research and supporting the development of research and policy leaders.

“The next chapter for the Dental Health Unit aims to enhance our impact in areas such as dental public health, behavioural science and clinical study management by building a robust network of collaborations with leading academic institutions.

"We will strategically expand our PhD program across renowned universities throughout the UK, Europe and North America.

"By fostering alliances with leading researchers, we are committed to advancing innovation and shaping thought leadership in oral health and behavioural insights.”

Professor Jan Clarkson, Academic Director at the DHU said: “This collaboration between the University and Colgate-Palmolive aims to establish the DHU as a strategic hub for advancing oral health behaviour change, leveraging behavioural insights, and innovative oral health research to deliver impactful, scalable outcomes that improve public health policies and oral health globally.

“This long standing private-public collaboration endeavours to advance global oral health research and education, leveraging industry and academic expertise to drive international excellence in scientific innovation, improve patient outcomes, and shape public health policies.”

Maria Ryan, DDS, PhD, Executive Vice President Chief Clinical Officer, Colgate Palmolive, said: “Colgate-Palmolive’s purpose is to reimagine a healthier future for all. We are proud of the accomplishments of our longstanding partnership with the University of Manchester through this Dental Health Unit. The pioneer DHU at the University of Manchester has advanced oral health through innovative, multidisciplinary research streams for more than half a century, breaking down silos between academia, clinicians, industry, policy makers and the communities that we all serve. And our collaboration has served as a model for others globally, with our more recent DHUs based in Latin America and India.”

The study was carried out by University of Manchester and Manchester University NHS Foundation Trust  researchers.

The discovery was made when researchers looked at early data from volunteers in the ongoing community-based EARLY-HF study in Greater Manchester. When heart scans were offered to the 550 volunteers aged over 50 with cardiometabolic issues, researchers discovered that nearly one in 10 people (nine per cent) had already suffered a heart attack without realising it.

Almost a quarter (23 per cent) had undetected or poorly managed heart or circulatory problems which required medical attention.

To take part in the study, people had to have at least two health issues from a list of seven which affect millions of people in the UK. These included high blood pressure, type 2 diabetes, coronary heart disease, the lung condition chronic obstructive pulmonary disease (COPD), the heart rhythm problem atrial fibrillation, obesity and chronic kidney disease.

The most common issues for study participants were pre-existing high blood pressure, which had already been diagnosed in 88 per cent of the study group, and obesity, which affected 70 per cent. Meanwhile 42 per cent of the volunteers had diabetes.

Led by Consultant Cardiologist at Manchester University NHS Foundation Trust and Professor of Cardiovascular Medicine at The University of Manchester, researchers wanted to understand the rate of hidden illness which had been unrecognised and untreated in this group.

They discovered almost two-thirds (60 per cent) had high blood pressure which was not under proper control or being effectively managed, raising their potential risk of a heart attack or stroke.

Among the study volunteers, 34 per cent were classified as living in an area that is among the top 20 per cent most deprived in England,¹ while 28 per cent lived in an area among the 20 per cent least deprived. There were more men than women in the study, with males making up 59 per cent of volunteers.

The researchers suggest the rates of undetected health problems found in Greater Manchester are likely to be reflected in communities across the UK.

British Heart Foundation Research Fellow at Manchester University NHS Foundation Trust and The University of Manchester, helped to run the study and presented the findings at the BCS conference in Manchester. He said:

“My colleagues and I were shocked by just how much unrecognised disease we found. While our study involves people who would be considered at higher risk of cardiovascular disease, finding so many people who had experienced a heart attack and didn’t know it was not something we ever anticipated going into this study.”

The Detecting EARLY Heart Failure in Greater Manchester (EARLY-HF) study aims to detect people at risk of developing heart failure earlier, within socioeconomically and ethnically diverse communities who may have reduced access to healthcare.

Heart attacks and other heart and circulatory issues, like those discovered in the study so far, can lead to heart failure – a condition which affects more than a million people in the UK and means the heart cannot pump blood properly, which can cause severe breathlessness and fatigue.

Most study participants (81 per cent) were recruited via their GP surgery, with another 12 per cent signing up after seeing a social media advert, and others recruited through community events or signposted to the project by family and friends.

Everyone involved in the study had blood tests, an ECG and a cardiac MRI scan, and answered questions about their health and medical history. These tests revealed that 125 people out of 550 (23 per cent) had a heart or circulatory issue that required medical attention.

On cardiac MRI scans, signs of scarring suggested that 46 people (nine per cent) had previously had a suspected heart attack. These diagnoses were confirmed by a consultant cardiologist, who looked over every scan. Letters were sent to people’s GPs, and they were then referred on for further tests and treatment.

Researchers found that 331 people in the study (60 per cent) had a blood pressure reading of 140/90mmHg or higher – the usual threshold for a diagnosis of high blood pressure (hypertension).

While 27 of these were undetected cases of high blood pressure, 304 people (92 per cent of them) were known to have it when they joined the study, with 224 already taking blood pressure-lowering medication. The researchers say this suggests their treatment plan was inadequate, as it had not brought their blood pressure down to a normal level.

Blood tests revealed 162 people (30 per cent) had elevated levels of the protein NT pro-BNP - a sign that their heart was under strain.

The study continues to recruit people in Greater Manchester with at least two cardiometabolic conditions – related to the heart, blood vessels or metabolism.

Professor Bryan Williams, Chief Scientific and Medical Officer at the British Heart Foundation, said:

"These shocking findings should ring alarm bells for our healthcare leaders. They show that our current approach to prevention isn’t fit for purpose, and too many people are slipping through the gaps as a result.

“All too often we see patients too late, when years of living with treatable risk factors like high blood pressure or high cholesterol have built up leading to heart attacks or heart failure. We have made huge strides in our ability to treat cardiovascular disease over the past 65 years, but right now we’re missing opportunities to prevent it in the first place. The picture this study paints won’t improve without a radical shift in how we identify and treat people at risk of cardiovascular disease.”

Professor Chris Miller, Professor of Cardiovascular Medicine and Consultant Cardiologist at The University of Manchester and Manchester University NHS Foundation Trust, who leads the EARLY-HF study said: “These findings underscore the need to address disparities in cardiovascular disease detection, healthcare access, and outcomes, including by engaging people through non-traditional channels such as text messaging and social media.”

Lead researchers and will trial the new course which has been shown to improve the way carers and people with dementia communicate with each other across England.

Difficulties communicating can result in a person with dementia losing confidence, withdrawing during interactions, or feeling disconnected from and devalued by the other person.

However, University of Manchester led research has shown that interventions focusing on communication can improve the person with dementia’s communication and behavioural symptoms.

Carers reported positive experiences of using the method called , a detailed study of the experience of 15 carers published in the journal showed.

And a second NIHR-funded study, published in found it was possible to measure participants psychological health, quality of life and service use when trialling the course.

Now the research team are able to progress to a multi-centre trial of the method across three proposed sites in England, thanks to the NIHR funding. The course will be offered across Greater Manchester with Greater Manchester Mental Health NHS Foundation Trust as the lead site.

The course, pioneered by Manchester’s Dr Lydia Morris and Professor Warren Mansell brings a glimmer of hope to the 700,000 people supporting a family member, partner, or friend with dementia.

Empowered Conversations uses evidence based psychological and communication theories to support carers to improve relationships and reduce stress.

For example, it uses Mentalisation Theory, which is about understanding our own thoughts and feelings while recognising that others have their own minds with different perspectives.

Professor Berry from The University of Manchester is also Mental Health Co-Theme Lead at the NIHR Manchester Biomedical Research Centre and Co-Director of the Complex Trauma and Resilience Research Unit at Greater Manchester Mental Health NHS Foundation Trust.

She said: “In dementia care, relationships often change dramatically, for example, a child may become the carer of a parent, or a spouse may shift from partner to caregiver.  Carers often face a painful conflict between remembering the person as they used to be and coping with who they have become.

“Seeing someone who looks the same physically but has changed in memory, personality, and communication can feel confusing, distressing and bring a sense of loss and grief.

“Stress associated with these changes in close relationships can make it harder to understand and interpret another person’s thoughts and feelings.  While some carers adapt by adjusting their expectations and priorities, this kind of coping does not happen easily or automatically. This is where learning skills in mentalisation can help.”

Among the positives, carers said the course resulted in changes to themselves, their relationships, and their communication skills.

Participants also described letting go of their expectations of what the person should be able to do and replacing that with more realistic goals.

Dr Morris, who is a Senior Clinical Lecturer and Clinical Psychologist at the University, added: “In a landscape where provision of post-diagnostic dementia support is variable or limited, it appears that Empowered Conversations can offer carers an intervention that is appreciated and accessible.

“Communication difficulties are associated with increased carer stress and burden and can contribute to the breakdown of the interpersonal relationship between the carer and person with dementia.

“Training does exist, but it focuses on practical communication skills without addressing the emotional and relational contexts of care and communication.

“However, the carers we worked with reported positive experiences of participating in Empowered Conversations and valued meeting people who, despite sometimes different circumstances, shared their understanding of supporting someone with dementia.

“The course supported participants to rethink communication and have a greater appreciation of the other person’s perspective during everyday interactions.”

Bangladesh has just approved one of the largest river engineering projects its history: the Padma Barrage, a vast river-control project intended to restore water in the country’s drought-prone southwest.

It comes at a dangerous moment for South Asia’s rivers. China is building the upstream on the Brahmaputra, India is accelerating its own , and the treaty governing Ganges water-sharing between India and Bangladesh expires in December 2026.

Rather than easing regional water insecurity, the Padma Barrage risks adding to a cycle of unilateral river engineering across the subcontinent. South Asia is entering a regional dam-building race – without the institutions needed to share its rivers.

Bangladesh’s water crisis

Supporters say the barrage is a pragmatic response to chronic water insecurity in Bangladesh. The country sits at the end of the vast Ganges-Brahmaputra river system, where rivers that originate in the Himalayas spread into thousands of channels before they reach the sea. Despite all this water, the main river channels are and some smaller rivers are disappearing rapidly.

The Farakka Barrage in India, and the proposed Padma Barrage downstream. 

Bangladesh did not create this problem alone. Since the 1970s, the Farakka Barrage, built across the Ganges upstream in India, has diverted water towards the huge city of Kolkata to flush sediment away from its port.

The consequences for Bangladesh are well documented. Its rivers have dried up and become less navigable. They have also become saltier, groundwater levels have declined, and severe riverbank erosion has occurred.

Farming has become more difficult and fish stocks have declined. These environmental pressures have forced many people to migrate out of the country.

Most critically, the reduced flow of freshwater has harmed — the world’s largest mangrove forest, shared between Bangladesh and India. There, elevated salinity has caused widespread among mangrove trees and significant biodiversity loss.

The promise – and risks – of Padma Barrage

When complete, the centrepiece of the Padma Barrage will be a huge dam more than two kilometres long. It is designed to store water during the monsoon season and release it in the drier months, helping reduce salinity intrusion by maintaining freshwater flows and pushing saline water further downstream during the dry season.

In theory, the barrage will revive a host of smaller rivers in western Bangladesh. The it will support irrigation across much of the country, while increasing rice and fish production.

The proposed Padma Barrage will span the Ganges river system’s largest channel in Bangladesh.

Yet the project raises a series of that deserve serious scrutiny.

The most immediate relates to silt, because the Ganges is an exceptionally sediment-heavy river. A dam or barrage causes the river water to lose speed and the energy required to carry sediment, which is dumped upstream.

This is already a severe problem . More than a million people have been displaced from over the past three decades, as banks have been eroded and floods have become more intense.

Constructing a second major barrier downstream – the Padma Barrage – risks compounding these effects, potentially trapping additional sediment loads between the two structures and intensifying flooding pressure.

The consequences downstream could be equally serious. The diversion of water into southwestern river channels — the stated objective of the project — implies reduced flows in the main river systems. If these flows aren’t strong enough to push back salty tidal waters, then parts of coastal Bangladesh, rather than benefiting from improved water security, could face accelerating salinisation.

There is a deeper irony here. Bangladesh is responding to the damage caused by India’s Farakka Barrage with a major barrage of its own.

Farakka was built to solve an economic problem upstream, but imposed major environmental costs downstream in Bangladesh. Those economic problems are still unsolved – Kolkata port still suffers from silt and needs constant dredging.

Critics fear the Padma Barrage could reproduce the same pattern: large environmental disruption without the promised benefits. In other words, the same engineering approach that damaged Bangladesh may soon be reproduced within that country.

A regional struggle over rivers

The project also depends on sufficient water continuing to flow into Bangladesh. But China – alongside planned hydropower projects across India, including plans to – could significantly reduce the volume of water entering Bangladesh in future. If that happens, the Padma Barrage may not have enough water to work as intended.

The timing also matters. The between India and Bangladesh expires in December 2026, and governs the same flows the Padma Barrage is designed to manage. Rather than strengthening Bangladesh’s position ahead of treaty talks, the project could weaken its case for demanding more water from India by signalling that it can cope with reduced flows.

Several rivers that the barrage aims to revive flow through both India and Bangladesh, meaning restoration will require cooperation between the two countries, rather than infrastructure alone.

That makes Bangladesh’s 2025 accession to the particularly significant. As the first South Asian country to join the treaty, Bangladesh now has a stronger legal basis to push for more equitable water-sharing, particularly as the Ganges treaty negotiations approach.

Dams cannot replace diplomacy

The Padma Barrage is not an inherently misconceived project. Bangladesh’s water crisis is real, and the political pressure to respond is genuine.

But without renewed water-sharing agreements and stronger cooperation with neighbouring countries, this new barrage risks repeating the pattern of unilateral river engineering that has already destabilised South Asia’s waterways.

Infrastructure that outpaces diplomacy is a familiar reason for failure in the region. The challenge for Bangladesh is to ensure the barrage becomes part of a strong legal and diplomatic framework for river cooperation – not another step in an escalating cycle of hydropolitical competition.

A new study led by researchers at The University of Manchester has carried out the first full environmental life‑cycle cost analysis of using abandoned onshore oil and gas wells to generate geothermal electricity.

Published in Applied Thermal Engineering, the research assesses not only the financial costs of repurposing old wells, but also the often overlooked environmental and human health impacts, such as air pollution and climate damage.

The findings show that while repurposed geothermal systems currently produce electricity at a higher cost than conventional geothermal power, they deliver substantially lower environmental and health costs, particularly by avoiding new drilling and reducing pollution linked to fossil fuel infrastructure.

Turning legacy fossil assets into clean energy

Across Europe and globally, hundreds of thousands of oil and gas wells are approaching the end of their productive life. Safely sealing and monitoring these wells is costly, and poorly managed sites can pose long‑term environmental risks.

The Manchester team explored whether these existing wells could instead be given a second life as geothermal energy sources, using underground heat to generate electricity.

“Existing oil and gas wells already reach deep underground areas where heat from the Earth can potentially be used for geothermal energy” said , Research Associate at The University of Manchester. “Our research asks whether we can turn this legacy infrastructure into part of the climate solution, rather than treating it solely as a liability.”

The study analysed three repurposing approaches:

• using two fully abandoned wells
• converting a single abandoned well
• turning late-life wells that increasingly produce water rather than oil and gas

These were compared with a conventional, purpose‑drilled geothermal power plant.

Cleaner, but not yet cheaper

The analysis found that repurposed well systems can have dramatically lower environmental impacts, particularly for air pollutants that affect human health. In some cases, environmental damage costs were reduced by more than 80% compared with a standard geothermal plant.

However, because the assessed repurposed systems are typically small and generate relatively little electricity, their cost per unit of power remains high. Electricity generated from repurposed wells currently costs more than from large‑scale geothermal, wind, solar or nuclear power.

, Senior Lecturer in Sustainable Chemical Engineering at The University of Manchester said “The challenge is not that repurposed geothermal is dirty or inefficient – it’s that it’s operating at pilot scale. When costs are spread over very small electricity output, the price per kilowatt‑hour inevitably looks high.”

Why environmental costs matter

A key innovation of the study is that it places environmental damage and human health impacts into monetary terms, allowing these costs to be compared directly with financial ones.

When these external costs are included, repurposed geothermal systems perform particularly well compared to fossil fuels. The study shows that coal and gas power impose environmental costs over 100 times higher than repurposed geothermal options.

What needs to change

The study stresses that repurposing oil and gas wells is not a silver bullet, but could play an important role in a diversified, low‑carbon energy system, especially if supported by the right policies.

Key recommendations include:

• Targeted incentives for early‑stage geothermal projects using existing wells
• Scaling up projects by clustering multiple wells together
• Clear rules on long‑term responsibility and well integrity
• Better integration of environmental and health costs into energy policy decisions

Crucially, the research suggests repurposing could help regions historically dependent on fossil fuels transition skills and infrastructure into clean energy, supporting a fairer, more inclusive energy transition.
