developed by ooms nederland holding in collaboration with wth and tipspit, road energy systems [via][alt] extracts energy from asphalt concrete.
the system exploits the heat-absorbing capacity of asphalt concrete, which is enhanced by its black color. the thermal energy produced is used to cool buildings, houses and roads in summer and heat them in winter.
research has shown that road energy systems cuts co2 emissions by 50% compared to conventional heating systems and minimises chloride use [salt for icy roads].
