No. 225: Japanese technology of solar air-conditioning goes to UAE (January 7, 2011)

Japan’s Ministry of Economy, Trade and Industry (METI) is scheduled to start the substantiative experiment of air-conditioning using solar heat in United Arab Emirates (UAE) this spring. Japan wishes to introduce its technology to UAE that is promoting the urban concept of zero carbon and zero wastes and examine how effective Japanese technology is and how long it takes to recover investment. The experiment will be performed jointly by Japan’s New Energy and Industrial Technology Development Organization (NEDO) and a government-affiliated agency of Abu Dhabi Emirate. This is part of the cooperation Japan gives to the Masdar city concept that started in 2006 in Abu Dhabi. In the experiment, vapor generated by heat collected by the large-scale mirror built in the city will be used for air-conditioning with the help of the heat exchange using the temperature difference. The experiment will study cooling efficiency and profitability against investment cost in the experiment. It is a three-year experiment, and Japan will invest about 3 billion yen. Japan wishes to promote the export of infrastructure to UAE and strengthen the relations with UAE on which Japan greatly depends for oil import. METI has already decided to perform substantiative experiment for photovoltaic generation in Morocco and for solar heat generation in Tunisia.
