Now, a newly announced fully funded PhD project at the Department of Earth and Environmental Sciences at The University of Manchester is aiming to unlock the geothermal secrets buried beneath Northwest England. Supported by the Engineering and Physical Sciences Research Council (EPSRC) and the UK Energy Futures Consortium, the research could provide critical insights into how geothermal resources can contribute to the United Kingdom's ambitious Net Zero goals.
As nations worldwide search for reliable, low-carbon energy sources capable of providing heat around the clock, geothermal energy is increasingly emerging as a strategic solution. Unlike intermittent renewable technologies, geothermal systems can deliver continuous heat and power regardless of weather conditions. The challenge, however, lies in accurately identifying, modelling, and developing these underground resources.
This groundbreaking doctoral research seeks to tackle precisely that challenge.
Why Heat Decarbonisation Matters
When discussing climate change mitigation, electricity often receives the most attention. However, heating homes, businesses, and industrial facilities accounts for a significant share of greenhouse gas emissions in the United Kingdom.
The UK's legally binding commitment to achieve Net Zero emissions by 2050 requires a dramatic transformation of the heating sector. Natural gas currently dominates domestic and commercial heating, making the search for sustainable alternatives increasingly urgent.
Geothermal energy offers a unique opportunity because it provides direct heat rather than converting heat into electricity first. This makes geothermal particularly attractive for district heating networks, industrial facilities, universities, hospitals, and municipal infrastructure.
Yet despite its promise, the UK's geothermal potential remains poorly understood compared to countries such as Iceland, New Zealand, Kenya, and parts of the United States.
The Manchester-led research project aims to change that.
Investigating Northwest England's Hidden Energy Resource
Northwest England presents an intriguing geological puzzle.
The region's subsurface contains a diverse collection of geological formations formed over hundreds of millions of years. These include Late Paleozoic and Triassic rocks, highly permeable red bed sandstones, carbonate formations, volcanic sequences, and former coal mining areas.
Each geological unit possesses distinct characteristics that influence its geothermal potential.
Key factors include:
- Rock permeability
- Porosity
- Thermal conductivity
- Heat capacity
- Depth
- Groundwater flow characteristics
Together, these properties determine whether a formation can effectively store and transmit heat.
Unfortunately, significant uncertainty remains regarding many of these parameters across Northwest England. This uncertainty complicates investment decisions and geothermal development planning.
The PhD project seeks to reduce these uncertainties through advanced geological modelling and geothermal resource assessment.
Building on Existing Geological Knowledge
One of the most exciting aspects of the project is that researchers will not be starting from scratch.
The study will build upon extensive existing datasets, including:
- Onshore seismic surveys
- Borehole geophysical data
- Geological databases
- Previous geothermal investigations
- Existing 3D geological numerical models
Using these resources, the successful PhD candidate will refine and enhance current geological models to better understand geothermal opportunities within specific target areas.
This approach represents a major advancement over traditional geothermal exploration methods, which often rely on sparse datasets and localized investigations.
By integrating large-scale geological information into sophisticated 3D models, researchers can generate far more accurate assessments of subsurface heat resources.
Three Major Geothermal Targets
The project will focus on three particularly promising geothermal opportunities.
1. Lower Carboniferous Limestone Beneath Greater Manchester
One of the primary study areas involves the Lower Carboniferous limestone formations located beneath Greater Manchester.
Carboniferous limestones are known in many regions worldwide for their capacity to store and transmit fluids through fractures, faults, and solution-enhanced pathways.
Researchers will investigate:
- Heat resource potential
- Fluid circulation patterns
- Reservoir performance
- Economic viability
- Development scenarios
If successful, these formations could support future geothermal heating projects serving urban populations and industrial users.
2. Coal Mine Heat Beneath Northeast Manchester and Oldham
Abandoned coal mines are increasingly being recognized as valuable geothermal assets.
When mines close, underground workings gradually fill with water. These flooded mine systems often maintain stable temperatures capable of supporting low-carbon heating and cooling applications.
The Manchester research project will examine:
- Heat extraction opportunities
- Cooling applications
- Fluid movement pathways
- Long-term sustainability
- Economic feasibility
Coal mine geothermal projects are already attracting attention across Europe as communities seek productive uses for former mining infrastructure.
If successfully developed, these systems could help transform former industrial liabilities into valuable clean energy assets.
3. Sandstone Reservoirs Across Northwest England
The third major focus area involves Carboniferous, Permian, and Lower Triassic sandstone formations.
Sandstones often represent excellent geothermal reservoirs due to their:
- High permeability
- Significant porosity
- Large storage capacity
- Extensive regional distribution
Researchers will investigate the potential for both heat production and thermal energy storage.
Thermal storage is becoming increasingly important as energy systems evolve. Excess heat generated during periods of low demand can potentially be stored underground and recovered later when required.
This capability could dramatically enhance energy system flexibility and resilience.
Advanced Modelling at the Heart of the Research
Modern geothermal development depends heavily on sophisticated computer modelling.
The PhD researcher will employ advanced geological and geothermal simulation tools to create detailed representations of subsurface conditions.
The project includes several interconnected work packages.
Work Package 1: Data Collection and Interpretation
The first phase focuses on data acquisition and preparation.
Activities include:
- Reviewing previous geological models
- Downloading open-access datasets
- Quality assurance and quality control
- Database construction
- Seismic interpretation
- Training in geothermal modelling techniques
This foundational work ensures that subsequent modelling efforts are built upon robust geological information.
Work Package 2: Refining 3D Geological Models
The second stage involves enhancing existing three-dimensional geological models.
Using industry-standard software such as Petrel, researchers will model critical reservoir properties including:
- Geological facies
- Porosity
- Permeability
- Thermal conductivity
- Specific heat capacity
The resulting models will provide unprecedented detail regarding geothermal resource distribution throughout the study area.
Work Package 3: Geothermal Simulation
The third work package represents the technical core of the project.
Researchers will simulate:
- Fluid flow behaviour
- Heat transport
- Reservoir performance
- Resource longevity
- Production scenarios
These simulations help answer critical questions regarding how geothermal systems might perform over decades of operation.
Work Package 4: Economic Assessment
Technical feasibility alone does not guarantee project success.
Economic modelling will therefore evaluate geothermal development opportunities under various market conditions and policy scenarios.
Factors considered may include:
- Energy prices
- Capital costs
- Operating expenses
- Carbon pricing
- Government incentives
- Heat demand profiles
The objective is to identify commercially viable geothermal development pathways.
Work Package 5: Dissemination and Industry Engagement
The final stage focuses on communicating findings.
Outputs will include:
- Peer-reviewed journal publications
- Conference presentations
- Industry reports
- Sponsor briefings
These activities ensure that research findings contribute directly to future geothermal development efforts.
Why This Research Matters
The significance of this project extends far beyond academia.
If successful, the findings could influence how geothermal resources are evaluated and developed across the United Kingdom.
Several major benefits could emerge.
Supporting Net Zero Targets
Low-carbon heating remains one of the most challenging sectors to decarbonize.
Geothermal energy provides an attractive solution because it delivers continuous, renewable heat with minimal emissions.
Accurate resource assessments can accelerate deployment and reduce investment risk.

Research initiatives such as this University of Manchester PhD project represent critical steps toward unlocking that potential.
By combining advanced geological modelling, geothermal simulation, economic analysis, and industry engagement, the project aims to provide a clearer picture of how Northwest England's hidden heat resources could contribute to the country's energy future.
The findings may help guide future investments, reduce exploration risk, and accelerate the deployment of geothermal technologies capable of delivering reliable, low-carbon heat for decades to come.
As the race toward Net Zero intensifies, understanding what lies beneath our feet may prove just as important as harnessing the energy of the sun, wind, and oceans.
For Northwest England, the next major renewable energy opportunity might not be visible on the surface at all—it may already be waiting deep underground.
