Geothermal Energy for the Agriculture Sector

The agriculture sector faces increasing pressure to reduce emissions, stabilise energy costs, and meet sustainability targets while ensuring productivity and resilience. Geothermal energy provides a reliable, low-carbon alternative to fossil fuel-based systems, delivering heat and cooling directly from the ground to support a wide range of agricultural operations.

Star Energy is able to offer geothermal solutions for farms, agricultural estates, and agri-tech businesses throughout the UK. Drawing on internal knowledge in planning, drilling, system design, and commissioning, we can support clients from initial feasibility assessments through to operations and maintenance, depending on project requirements.

Heating and Cooling Solutions for Agricultural Use

Many agricultural operations require substantial thermal input for processes such as greenhouse heating, animal housing, grain drying, and product storage. Geothermal systems offer consistent base-load heat that is unaffected by weather variability, fuel supply chains, or energy-price volatility.

In controlled environment agriculture (CEA), including greenhouses and vertical farms, geothermal energy can support optimal growing conditions with precise control over temperature and humidity. For livestock operations, geothermal heating improves animal welfare while reducing emissions associated with gas and oil-fired boilers.

We also deliver systems that combine geothermal heating with water-to-water or water-to-air heat pumps, allowing for cooling applications in food processing, storage facilities, and agricultural product preservation. These systems can be configured for single-site use or connected to shared energy infrastructure across agricultural estates or co-operatives.

Site Feasibility and Geothermal Resource Mapping

A significant fraction of the agricultural land in the UK is often above suitable geological formations for deep geothermal development. Star Energy uses detailed subsurface datasets, combined with site-specific assessments, to identify viable locations for geothermal wells and associated surface plant. Key customer factors in agricultural feasibility studies include proximity to energy demand, year-round thermal load, available drilling access, and utility infrastructure. Where legacy geological or seismic data is limited, we can conduct new geophysical surveys or thermal response testing to inform development potential.

Our in-house team prepares detailed geothermal prognoses and well design concepts, ensuring that any proposed system aligns with the operational needs and spatial constraints of the farm or facility.

Integration with Renewable and Sustainable Farming Systems

Geothermal energy is often deployed alongside other renewable technologies in the agriculture sector, including solar PV, wind, and anaerobic digestion. We support integrated energy systems that combine geothermal with other sources, providing a balanced and resilient approach to farm energy management. Systems can be configured to connect to thermal storage, heat recovery systems, or local energy centres, depending on the scale and operational model. For agricultural businesses participating in sustainability certification schemes or ESG reporting, geothermal offers a measurable and reportable reduction in carbon intensity.

Where district or shared heating networks exist—such as within food production parks or agri-business clusters—Star Energy designs and installs connection-ready geothermal systems that support collaborative energy models. Having other commercial offtakes for the heat produced by the geothermal system means that the offered price of heat can be made even more attractive.

Supporting Decarbonisation in Food and Farming

Agricultural emissions are a major contributor to the UK’s overall carbon footprint, with heating and energy use representing a significant share. By replacing or displacing fossil fuels with geothermal energy, farms and food producers can reduce Scope 1 emissions while improving long-term energy cost certainty because of the enhanced energy security that having an indigenous source of heat offers.

We work with farmers, estate managers, agri-tech developers, and industry consultants to align geothermal deployment with environmental goals and compliance requirements. Our systems are designed to operate efficiently at low flow temperatures, enabling heat delivery that is compatible with modern heating distribution systems and low-carbon retrofit technologies.

Whether the goal is decarbonising an existing operation or futureproofing a new-build agricultural facility, we provide full engineering, environmental, and commercial support throughout the project lifecycle.

Long-Term Operational Benefits

Geothermal systems are designed for long-term reliability and minimal maintenance.

Once operational, they provide a consistent thermal supply with high availability and low operating costs. This is particularly important in agricultural settings where continuous process heat or controlled environmental conditions are required to avoid disruption to crops or livestock.

The subsurface infrastructure (wells and heat exchangers) typically has a lifespan of over 50 years or longer, while surface equipment such as pumps and control systems can be maintained or replaced within standard asset management cycles. Star Energy also offers long-term performance monitoring and O&M services to ensure system efficiency and availability across the lifetime of the asset.

Working with Star Energy

Star Energy has decades of experience in onshore subsurface development and energy project delivery. Our team includes geologists, drilling engineers, energy system designers, and project managers—all working together to deliver geothermal energy systems that meet the specific needs of the UK agriculture sector.

We operate as a full turnkey partner, covering every aspect of geothermal development: from early feasibility and permitting through to procurement, construction, commissioning, and ongoing operation. We also offer consultancy support and advisory services for farms or estates considering geothermal as part of their wider energy strategy.

Whether you operate a horticulture business, livestock farm, agri-tech innovation centre, or multi-site food production facility, Star Energy can provide a practical and commercially viable geothermal solution to help meet your operational and sustainability goals.

Our Projects - Geothermal

Manchester University NHS Foundation Trust

The Carbon Energy Fund released a tender to select Innovation Partners to work with NHS Trusts across the UK to identify Low Carbon Heat opportunities. We were selected as preferred Partner by the CEF and Manchester University NHS Foundation Trust for the Wythenshawe Hospital.

Manchester Therme Group

Feasibility work for an innovative geothermal geo-exchange solution for the Therme Wellbeing Resort in Trafford Park, Manchester. A trial borehole was drilled and thermal response testing carried out to determine the potential capacity for heat and cooling supplies to the development. This work identified that the Trafford Park area has amongst the highest capacity in the country.
