Japanese Airport to Store Winter Snow for Summer Air Conditioning

New Chitose Airport in Hokkaido, Japan plans to start storing winter snow for summer cooling in 2010. The winter snow will provide 30% of the summer cooling needs. EcoGeek explains this clean technology:

The snow will be covered by heat-insulating materials, which should retain about 45% of the snow collected. The remaining snow will then be used to chill the liquid of the building's cooling system. According to Japan Today, the practice could result in a 2,100 ton reduction in CO2 emissions per year.

Hokkaido's annual snowfall is between 20 to 30 feet. Hopefully this innovative technology will catch on in other snowy cities around the world.
