In Tai\u2019an, east China\u2019s Shandong Province, a massive power facility has risen from a once-abandoned rock salt mine, reshaping the skyline of this once resource-dependent city.<\/p>\n
\u201cThe station is designed to store energy for eight hours and generate electricity for four hours, with an annual output of up to 460 million kilowatt-hours. That is enough to meet the yearly electricity demand of more than 200,000 households,\u201d said project manager Liu Shaoyong with China Energy Engineering Group Co., Ltd., the facility\u2019s operator.<\/p>\n
As the company\u2019s first commercial compressed air energy storage project, the station turns underground salt caverns left by years of mining into \u201cenergy reservoirs.\u201d During off-peak hours, electricity is used to compress air and store it underground. The compressed air is then released to generate power during peak demand.<\/p>\n
In recent years, China has made several breakthroughs in renewable energy generation.<\/p>\n
By 2025, renewable energy installations accounted for more than half of the country\u2019s total installed capacity, driven by the use of innovative technologies. This has provided strong momentum for both China and the world in their clean energy transition.<\/p>\n
In Tai\u2019an, renewable energy technologies are not only accelerating the development of new power storage models but also improving the grid\u2019s ability to absorb renewable power, ensuring a stable and secure energy supply.<\/p>\n
\u201cWe actively track electricity demand and provide technical support for project commissioning and grid connection, streamlining comprehensive grid integration services,\u201d said an official with the dispatching center of the State Grid Tai\u2019an power supply company.<\/p>\n
By 2030, the city\u2019s installed capacity of new-type energy storage is expected to approach 5 million kilowatts.<\/p>\n
With close cooperation between enterprises and power authorities, a growing number of clean energy projects are being put into operation across China, reshaping the country\u2019s energy landscape.<\/p>\n
Last October, the world\u2019s largest 26-megawatt offshore wind turbine, independently developed by China\u2019s Dongfang Electric Corporation, was successfully connected to the grid in waters off Shandong Province, setting new global records for both single-unit capacity and rotor diameter.<\/p>\n
According to the company, under full-load conditions, each rotation of the turbine generates 62 kilowatt-hours of electricity. At an average wind speed of 10 meters per second, a single unit can produce 100 million kilowatt-hours annually \u2014 enough to power 55,000 households while saving 30,000 tonnes of standard coal and reducing carbon dioxide emissions by 80,000 tonnes.<\/p>\n
In east China\u2019s Shanghai, a commercial underwater data center powered by offshore wind farms began operation in February, aligning surging computing demand with renewable energy supply.<\/p>\n
Offshore wind turbines located above the data center are designed to supply electricity directly, enabling on-site consumption and avoiding energy losses typically associated with long-distance transmission.<\/p>\n
At full-load operation of 24 megawatts, the project\u2019s annual carbon reduction is equivalent to the annual carbon absorption of about 1.6 million trees.<\/p>\n
Similar clean energy-powered data centers are also being developed in northwest and southwest China.
\nChina is accelerating the construction of renewable energy infrastructure to support its fast-growing digital economy while effectively reducing carbon emissions.<\/p>\n
In September last year, China pledged to reduce net greenhouse gas emissions across its economy by 7 to 10 percent from peak levels by 2035.<\/p>\n
To achieve this goal, China\u2019s installed capacity of renewable energy has already surpassed that of coal-fired power.<\/p>\n
As China rapidly expands its clean energy infrastructure, it is also sharing the spillover benefits of its technological innovation with the rest of the world.<\/p>\n
At the Solar and Storage Live Africa 2026 exhibition held in Johannesburg in March, Chinese companies\u2019 photovoltaic equipment and smart energy solutions drew widespread attention.<\/p>\n
Qhakazile Mathebula, general manager for digital energy at City Power Johannesburg, welcomed the strong presence of Chinese firms and highlighted their contribution to Africa\u2019s energy transition.<\/p>\n
\u201cWe welcome the participation of Chinese renewable energy companies, whose investments and technologies are helping accelerate Africa\u2019s shift toward cleaner and more sustainable energy,\u201d she said.
\nChina\u2019s ability to deliver cost-effective and scalable solutions is critical as African countries are working to expand energy access and address supply constraints, Mathebula added.<\/p>\n
\u201cAt the scale and pace that China is producing them (clean energy), plenty of things stand to be swept away including, quite possibly, the once seemingly intractable problems of energy poverty and fossil-fuel dependence,\u201d wrote Jeremy Wallace, a professor of China Studies at Johns Hopkins, in a recent column for Wired magazine.<\/p>\n","protected":false},"excerpt":{"rendered":"
