With a storage capacity of 2,8 GWh, the system uses salt caverns to innovate in compressed air energy storage, eliminating carbon emissions and achieving efficiency of over 60%.
In recent years, China has been surprising the world with gigantic and innovative projects in the area of renewable energy. This time, the country has raised its game by developing the largest compressed air energy storage (CAES) system in the world. The project, led by the Huaneng Group, is not only impressive in size, but also in its efficiency and contribution to global sustainability. But how does this system that promises to revolutionize the energy market work?
How does compressed air energy storage (CAES) work?
Imagine a spring being compressed to store energy. Now replace the spring with air and add a touch of High technology. CAES works like this: air is compressed and stored in large underground reservoirs, such as salt caverns. When energy is needed, this compressed air is released to drive turbines and generate electricity.
Most impressively, Jintan’s design does not use any external fuels. It reuses the heat generated during air compression, making the system highly efficient and eliminating carbon emissions. In simple terms, it’s like having a machine that turns excess energy into clean, ready-to-use reserves.

The Jintan Project: A Milestone on a Global Scale
The second phase of the Jintan project, located in Jiangsu province, is the star of the development. With two 350 MW units each, the system can store up to 1,2 million cubic meters of air, equivalent to an impressive 2,8 GWh of energy. That’s enough to meet the demand of thousands of homes for hours.
This new stage operates at an efficiency of over 60% and can be started in just five minutes, compared to 20 minutes for previous systems. These technological advances put Chinese CAES at the forefront of the energy sector.
This system is a game changer in the fight against climate change. By eliminating the need for fossil fuels to operate, the project dramatically reduces carbon emissions. With China leading the demand for coal, initiatives like this signal a significant shift towards a cleaner future.
The role of salt caverns in energy storage
Salt caverns play a key role in the Jintan project. Because they are naturally airtight and resistant, these geological formations are ideal for storing large volumes of compressed air. Studies indicate that these caverns could be used in the future to store hydrogen, a promising bet in the global energy transition.
Several European countries are already exploring the use of salt caverns for hydrogen distribution. This puts the Jintan project in a strategic position not only for the present, but also for the next steps in the renewable energy sector.
China's impact on the renewable energy race
China is already known for its ambitious renewable energy projects, such as offshore wind turbines and giant liquid batteries. Jintan’s CAES system joins that list, proving that the country is committed to finding storage solutions for its growing energy capacity.
What sets China apart is its scale: the country always thinks big. This is crucial at a time when global demand for clean energy is soaring. China’s energy transition is not just a domestic issue, but an example for the world.
The Future of Storage
With projects like Jintan, the future of energy storage looks bright. Technologies like CAES are essential to ensuring that energy generated by renewable sources is used to its full potential. The global challenge of meeting growing energy demand with clean solutions can be met with innovations of this magnitude.
The world’s largest compressed air power project is not only a technological feat, but also a symbol of China’s commitment to sustainability. Combining efficiency, innovation and positive environmental impact, the Jintan project is redefining the standards of the energy sector. As the world seeks alternatives for a greener future, initiatives like this show that large-scale solutions are the way forward. Are you ready to follow this transformation?
China is investing heavily in this as a way to obtain clean and renewable energy sources. The hydrogen plant, extracting it from seawater, is already a type of infinite source of clean energy from a practically infinite resource, since 70 percent of planet Earth is made up of salt water, and so we are able to make hydrogen without the risk of there being a possible end of this gas in nature, right?
Sensational!
