Presented by: Dr Stephen Thomas, OGI Groundwater Specialists Ltd
Designed to collect solar heat from a road surface, a Road Energy System (RES) comprises pipes and racking embedded within the asphalt layers of a road. Heat collected by fluid circulating within pipes in the road is transferred to the ground by water wells to be stored as heated groundwater in an underlying aquifer, or is stored as heated soil or rock using closed loop borehole collectors.
The benefits of a Road Energy System are substantial and include:
- Annual collection of 250kWh of heat per square metre of road surface
- Storage of heat in the ground can be up to 30°C
- Increasing the efficiency of a heat pump
- Reducing carbon emissions from a heat pump
- Reducing running costs of a heat pump
- Increasing a road’s lifetime by removing excess heat during hot weather
- Reversal of the system can defrost roads during freezing weather
- Collection and storage of coolth in winter can be used to provide cooling to buildings in the summer
A case study will be presented of a Road Energy System installed in County Durham where abandoned mine workings restricted the depth of borehole drilling, so making RES a necessity to ensure that the building could be heated and cooled entirely using a ground source heat pump.
