FAQS about China-europe solar thermal energy storage project

Where is a 100MW solar system being built?

The project in Turna, Xinjiang, China. Image: Lan Shengwen, a reporter from Gaochang District Media Center. A 100MW thermal solar and molten salt energy storage system in Xinjiang, China, is set to be completed and grid-connected by the end of the year, part of a project which has also deployed conventional solar PV.

How much energy does China have?

The total primary energy supply was 994.4 TWh, of which coal accounted for 77.2 % of the total. The installed capacities for thermal, hydro, wind, and solar power were 24.2, 1.1, 6.9, and 3.2 GW, respectively.

How are power generation technologies derived from the China Energy Statistical Yearbook?

The capacities and power generation of different power generation technologies were obtained from the China Electricity Statistical Yearbook . The fossil fuel consumption in the thermal power and DH sectors was derived from the China Energy Statistical Yearbook .

Is Turfan a'solar thermal energy storage & photovoltaic integration' project?

The first phase of the 1GW ‘solar thermal energy storage + photovoltaic integration’ project in Turfan, Xinjiang, has been completed, according to announcements from the State Grid Turfan Power Supply Company on PR Newswire and state-owned outlet Turfan Media Center.

What is thermal solar salt energy storage?

Thermal solar salt energy storage has in other instances meant using concentrated solar power (CSP) to heat and melt salt and store that thermal energy for charging, and then discharging the system by using the heat from the molten salt to power a turbine generator, after which the salt is circulated back into the system for ‘charging’ again.

Can STES improve wind and solar power integration?

The wind and solar power curtailments were reduced by 10 % and 50 %, respectively. Additional wind power integration occurred mainly in winter, which was the high-wind speed period, indicating that STES in the DH has considerable potential for increasing the degree of wind power generation integration.

The significance of giving priority to the development of solar thermal energy storage

To eliminate its intermittence feature, thermal energy storage is vital for efficient and stable operation of solar energy utilization systems. It is an effective way of decoupling the energy demand and generation, while plays an important role on smoothing their fluctuations.
