Quick Summary

China has started construction on the world’s first utility-scale power plant that combines supercritical CO2 technology with molten salt energy storage in Shandong province. The Ruitan demonstration project broke ground at China Huaneng’s Bajiao power station on September 16 and is set to begin operations next year. This facility aims to reduce waste by using excess electricity from coal units to heat molten salt, which then powers a supercritical CO2 unit during peak demand periods. The first phase will include a 50-megawatt supercritical CO2 unit and a 100-megawatt (400 megawatt-hours) molten salt storage system.

Story summary

On September 16, China broke ground on the world’s first utility-scale combined supercritical carbon dioxide power generation and molten salt energy storage project at China Huaneng’s Bajiao power station in Yantai, Shandong province. The project aims to reduce energy waste and improve grid stability by utilizing surplus electricity generated during low-demand periods to heat up molten salt, which is then used to produce electricity when demand peaks. The first phase of the Ruitan demonstration project includes a 50-megawatt supercritical unit and a 100-megawatt (or 400-megawatt-hour) molten salt energy storage system. According to state news agency Xinhua, the project is expected to go into operation next year.
