Shanghai jiaotong university research and development of molten salt solar energy storage technologies

Tesla sales soared in 2015, worldwide sales of more than 5 w m, thanks to the panasonic cylindrical battery, shipments to the 4. 5 GWH, fast-growing tesla, directly driven by the rapid growth of cylindrical battery, in 2016, cylindrical battery share nearly three.

a few days ago, Shanghai jiaotong university professor Deng Tao, TaoPeng associate professor in Energy& Environmental Science magazine reported a clever, simple strategy, can greatly accelerate the rate of molten salt storage system of solar thermal energy storage, completely will not affect the storage capacity at the same time.

in the energy storage system, they are set in the molten salt along the sun path of a magnetic drive mobile net emissions converter to absorb solar energy, can not affect the total capacity under the premise of the storage system of solar thermal energy storage rate increased by 107%. The magnetic acceleration of mobile storage strategy also supports a large area of energy collection and batch solar heat storage, with all kinds of existing heat exchange system integration, has a broad application prospect.

according to introducing, compared with the traditional fixed energy storage system, this kind of mobile system not only makes double energy storage rate, has realized the uniform temperature distribution, retained 100% of latent heat storage capacity, but also make it possible to have large area and batch solar heat storage. Combined with the existing heat exchange system, can be directly release the storage of high temperature heat, heating hot water or heating, even used in industry, such as to produce steam and power generation.

the results not only for the high temperature phase change materials and the sensible heat storage medium quickly and effectively provides a new method for solar thermal storage, but also consider the possibility of a scale and related issues, which laid a foundation for practical application in the future.
