China's First Photothermal Storage Project Built in Hebei

It was learnt that the ground-source heat pump of the “China Photovoltaic Energy Storage Ground Source Heat Pump Integrated Microgrid Demonstration Park”, the first integrated thermal storage and storage project in Shijiazhuang, was put into operation recently, and photovoltaic modules will be laid before the end of this year. The "photovoltaic energy storage ground source heat pump integrated microgrid demonstration park" is located in the High-tech Development Zone in Shijiazhuang City and is the first micro-grid demonstration park integrating photovoltaic, energy storage and ground-source heat pumps. The investment of the project is more than 10 million yuan and it is expected to be in 2013. Completed by the end of the year.

After the park is completed, it will use photovoltaics, electricity storage, and ground source heat pumps. The park uses photovoltaic modules installed on the roof to generate electricity, which not only solves day-to-day office work and lighting, but also stores excess power for cloudy and night use. In addition, ground-source heat pump technology has also been incorporated into the microgrid system for the first time, and the park can use geothermal energy to regulate indoor temperatures. The annual power generation capacity of the demonstration park is about 330,000 kilowatt-hours. The use of ground source heat pump systems saves 620,000 kilowatt hours of electricity annually. At the same time, it will reduce carbon dioxide emissions by about 304 tons, oxygen dioxide by about 9.5 tons, and nitrogen dioxide by 0.18 tons per year, saving 104.6 tons of standard coal-fired power.
