ICAX uses Interseasonal Heat Transfer to capture summer heat from Solar Runways and store the heat in ThermalBanks in the ground until heat is needed in winter to maintain Runway Systems above freezing point using a variant of underfloor heating.

Snow delays aircraft at Manchester Airport for seven hours on 20 December 2009
All BAA's London airport runways were closed in the first days of February 2009 by heavy snowfalls. Air traffic could have continued to flow if Heathrow, Gatwick, Stansted and Luton had used Interseasonal Heat Transfer to keep their runways clear of ice and snow.
See the extended report by Transport Research Laboratories on the Toddington demonstration of Interseasonal Heat Transfer using ThermalBanks: TRL report on IHT for roads.
