Speech by the host of the electrochemical energy storage power station technology exchange meeting

Why is electrochemical energy storage important?

Abstract: With the increasing maturity of large-scale new energy power generation and the shortage of energy storage resources brought about by the increase in the penetration rate of new energy in the future, the development of electrochemical energy storage technology and the construction of demonstration applications are imminent.

Which energy storage power station successfully transmitted power?

China’s largest single station-type electrochemical energy storage power station Ningde Xiapu energy storage power station (Phase I) successfully transmitted power. — China Energy Storage Alliance On November 16, Fujian GW-level Ningde Xiapu Energy Storage Power Station (Phase I) of State Grid Times successfully transmitted power.

What is Ningde Xiapu energy storage power station?

On November 16, Fujian GW-level Ningde Xiapu Energy Storage Power Station (Phase I) of State Grid Times successfully transmitted power. The project is mainly invested by State Grid Integrated Energy and CATL, which is the largest single grid-side standalone station-type electrochemical energy storage power station in China so far.

What percentage of energy storage projects are Lib projects?

According to the DOE OE Global Energy Storage Database, since 2010, more than 50% of energy storage projects are LIB projects . By contrast, although PHES accounts for 93% of the global storage capacity , many of PHES, particularly plants in Europe and US, were built before 1990 .

How does RTE affect energy consumption?

For a given amount of energy, the higher the power and energy densities are, the smaller the volume of the required energy storage system will be. Similarly, the higher the RTE is the lower energy consumption in the charge process is required, leading to lower operational cost.

Which EES technology has a high power density?

Flywheels and super-capacitors have very high power densities but relatively low energy densities. All mechanical EES technologies tend to have a long lifetime of 25–50 years. Most of electrochemical batteries, e.g., LIBs, have both high energy densities and high power densities.
