Power Road® heats and cools buildings

Power Road® stores renewable thermal energy in summer to heat your buildings in winter, and cool them in summer.

Power Road® cools urban heat islands

Power Road® lowers the temperature on your road surfaces by 10°C on average.

Power Road® improves safety

Power Road® clears ice and snow from your roads.

Power Road® harvests heat

Eurovia is using roads in new ways with Power Road®: it captures solar energy inside the road surface, in some cases stores that energy for several months, then transfers it to nearby buildings and other structures through heat pumps.
 
Power Road® heats and cools residential properties, business premises, swimming pools and sports facilities, using low-carbon technology, and cools paved surfaces in summer to help avoid urban heat islands.
 
Power Road® is Eurovia’s answer to help you on your energy and environmental transition.

How Power Road® works

Immediate and Delayed Operation

Solar radiation first heats the bituminous pavement of the roadway (1). This renewable heat is captured by integrating a heat exchanger into the surface layers of the pavement (at a depth of 5 to 8 cm) (2). This exchanger consists of a network of tubes—similar to those used in underfloor heating—through which a heat-transfer fluid circulates. Under the effect of solar radiation, the heat-transfer fluid gradually warms up, reaching temperatures of up to 35°C. This thermal energy can then be used on demand in two different ways (3): either for immediate use (4a) or for delayed use (4b).
