China has launched particulars of dozens of pioneering power storage tasks beneath improvement because it seems to construct out capability to match its booming wind and photo voltaic sectors.
China’s “extraordinary” development in inexperienced energy was just lately hailed by the Worldwide Power Company as serving to maintain the COP28 local weather summit’s objective of tripling renewables by 2030 inside attain.
Final yr, China commissioned as a lot photo voltaic as all the world did in 2022, whereas its wind energy additions additionally rose by 66% year-on-year.
This has put strain on its power storage sector to match the tempo and add sufficient capability to assist steadiness the nation’s grid between durations of excessive and low era from renewables.
China’s Nationwide Power Administration final month launched particulars of 56 pilot tasks that it mentioned demonstrated the diversified and high-quality power storage sector within the nation.
The most important of those by megawatt hours is a 300MW/1800MWh compressed air power storage venture positioned in China’s northern Gansu province. A number of different compressed air power storage tasks have been additionally listed with related capacities.

There have been greater than a dozen lithium-ion battery storage tasks listed, the biggest of which is a 550MW/1100MWh facility listed in China’s Internal Mongolia area.
Lots of the tasks are in the meantime utilizing redox movement battery chemistries to retailer power.
Additionally listed is a 10MW/80MWh carbon dioxide power storage pilot venture. An identical venture is at present being developed in Italy, with the developer successful the backing of Invoice Gates’ power innovation automobile and the EU.
A 26MW/100MWh gravity power storage venture in Jiangsu Province, simply north of Shanghai, can also be recognized. Though the itemizing doesn’t specify the venture developer, it seems more likely to be the 100MWh facility that was commissioned final yr by Switzerland-based Power Vault in the identical location.
Lastly, there are additionally three tasks utilizing flywheels for power storage listed, the biggest of which boasts 100MW of capability. Flywheels have been round for a very long time within the power storage market however have failed to achieve a lot traction up till now.
It was additionally just lately introduced that China is planning to show electrical automobiles into cell batteries that might help the grid and assist deliver extra inexperienced energy on-line, with trials of a brand new two-way charging system because of start in main cities subsequent yr.
