In order to implement "Science and Technology Cooperation Agreement of Tibet Autonomous Region Peoples Government and the Chinese Academy", Shengjie Ma, director of the Tibet Autonomous Region Science and Technology Agency, Jiahu Yuan, president of Chengdu Branch of Chinese Academy of Science, and their party visited DICP for project assessment "system integration of flow energy storage battery and its applied demonstration in solar power”, July 29.

Review meeting was hosted by Danping Jian, the Deputy Director of Tibet Science and Technology Department. Director Tao Zhang introduced the basic situation of DICP, and prospected the cooperation field of energy and Tibetan medicine. Shengjie Ma introduced the current situation of usage of solar energy and the main faced problem inTibet Autonomous Region. Huamin Zhang, the leader of 303 group, Detailed the Specific content, implementation plan, technology roadmap, assessment indicators of the project "system integration of flow energy storage battery and its applied demonstration in solar power”. After discussion, the experts agreed that all vanadium flow storage batteries will effectively accelerate the promotion and application of solar photovoltaic technology in the Tibet Autonomous Region, and will boost local economic and social development. The project was approved.After the meeting, accompanied with Prof. Huamin Zhang, the guests visited the different sizes of vanadium redox flow battery energy storage system developed by 303 group.

In July 2003, Chinese Academy of Sciences and the Tibet Autonomous Region signed the "Science and Technology Cooperation Agreement of Tibet Autonomous Region Peoples Government and the Chinese Academy", in order to promote Tibets economic and social development using the technology of Chinese Academy of Sciences and combined with Tibets unique geographical and climatic environment. Developing photovoltaic power plant has a unique geographical advantage in Tibet, where average annual sunshine is over 3,000 hours and it is Chinas largest area of solar radiation. From the 1980s, Tibet vigorously develop the usage of solar energy resources, had implemented the "Tibet Sunshine Project," "Light of Science project," "Tibet’s Ngari optical scheme" etc. At present, Tibet solar photovoltaic power generation capacity is more than 9 MW, and it has more than 300 seats of 10-100 kilowatts of photovoltaic power plant. Currently, the energy storage devices used in the PV power plant are the lead-acid battery. However, due to short cycle life, not the depth of discharge, higher maintenance cost of lead-acid battery, it increases operation and maintenance costs and decreases the long-running reliability of the photovoltaic power plant. Flow storage batteries are provided with high energy conversion efficiency, high electrical storage capacity, independent design of power and capacity, long cycle life. Its application will promote solar photovoltaic technology widely used in Tibet to boost local social and economic development.
