Geothermal

• Desk top evaluation of potential resource based on existing data from either previous mine workings or geological data
• Initial assessment of constraints and potential opportunities
• Review local mine abandonment plans form the Coal Authority.
• Georeferencing of mine plans in GIS
• Contact SEPA permitting department for acceptable parameters of discharged untreated minewater.
• Assess stability and openness of local mineshafts

• Assess onsite gravity discharge drainage designs and past remediation work.
• Contact Coal Authority to obtain data pertaining to the nearby gravity discharge(s) – flow rates, temperatures, chemistry, flow pathway and treatment.
• Identify best discharge(s) and mine access point(s) for exploitation.
• Assess water temperature, chemistry and flow of all available discharges through field sampling and flow measurement (if needed following purchase of CA data)
• Determine most favourable design concept.
• Outline design proposal for abstraction / discharge point(s), flow rate and available temperature (delta T) to inform pump, heat exchanger and heat pump capacity.
• Provide Risk Register with Mitigating Actions
• Provide indicative Project Development Timeline

• Determine possible sites for an abstraction or reinjection well.
• Evaluate potential well locations and map underground flow paths to determine optimal well design.
• Determine design supply to match heat demand (usually in conjunction with SEL).
• Obtain cost estimates for water treatment sites for different flowrates and treatment methods.
• Evaluate treatment vs reinjection.
• Design and price minewater heating system.
• Identify options for test drilling, outline value (data collection for de-risking resource, potential for repurposing wells for minewater heat abstraction), and obtain drilling / testing cost estimates

If the resource is assessed as being suitable we will prepare a comprehensive business case, to help you secure a funding for the project. Once funding is secured then we can manage all aspects of the development of your project which will include:

• Plan & commission test drilling programme (if required)
• Well and surface infrastructure design
• Procurement of drilling and top side engineering
• Construction management of the project
• Geothermal system commissioning
