China Just Installed The Largest Energy Storage Flow Battery in The World

Last week, China connected the largest power and energy storage flow battery ever produced to its electrical grid. The flow battery, called Dalian, has a capacity of 100 MW, which will be used to smooth out the peaks and valleys of renewable energy generation, providing energy at a constant level even when the wind isn’t turning the wind turbines or at night when the solar panels are generating energy.

China’s Energy Storage Project Could Reach 800 MWh

Two years ago, the responsible company demonstrated some details of the plant – Reproduction/YouTube

The flow battery project was developed by the group of Professor Dalian Xianfeng Li, from the Chinese Academy of Sciences, and the system was created and integrated by Rongke Power Co.

The stage that was inaugurated now by scientists is just the first one, for demonstrating large-scale chemical energy storage. The complete project is expected to reach 200 Megawatts or 800 megawatt-hours of electricity.

Flow Battery Uses Vanadium for Energy Storage

The Dalian installation in China uses vanadium flow battery energy storage technology. Since electricity is chemically stored in tanks, expanding long-term storage capacity is merely a matter of adding more tanks, thus this technology is also called a flow battery.

The flow battery operates through a reversible process called intercalation, where positively charged zinc ions are oxidized at the negative metallic zinc electrode, travel through the electrolyte, and insert themselves between the layers of vanadium oxide. This generates a flow of electrons in the external circuit, developing an electric current.

During charging, the reverse process occurs. This is a well-known and relatively simple technology; however, it is not considered the most environmentally friendly due to its chemically aggressive compounds.

Aneel Approves First Energy Storage Project in Brazil

The Brazilian National Electric Energy Agency (ANEEL) approved last year the first large-scale lithium battery energy storage project in the Brazilian transmission system.

The initiative is led by Isa Cteep, which will invest about R$ 146 million in a 30 MW energy storage system that will be installed at the Registro (SP) substation, aimed at supplying the Southern São Paulo coastline.

Libya built over 4,000 kilometers of underground pipelines to bring water from the Sahara to coastal cities in a project that the government itself called the Eighth Wonder of the World.

Desert sand, previously discarded for being too smooth for concrete, becomes an ecological brick in the United Arab Emirates, dispensing with Portland cement, curing at room temperature, and attempting to transform dunes useless for construction into raw material for a new arid engineering.

He transformed an abandoned plastic water tank into an underground house in the “hobbit hole” style, using only repurposed pallet wood, without heavy machinery or expensive labor.

China transforms desert-devastated area into the world’s largest artificial forest, planting trees for 60 years, blocking sand that reached Beijing, and creating a “green lung” of 92,000 hectares in a region once considered lost.

Toyota launches “family hybrid van” with 7 or 8 seats, 1.8 hybrid engine, fuel consumption of up to 23.8 km/l, and a price equivalent to about R$ 104,000 without taxes, below the Tiggo 8 Pro Plug-in Hybrid sold in Brazil: meet the Noah Hybrid 2026 in Japan.

Described by astronauts as one of the most unlikely natural phenomena on Earth, the Okavango Delta spreads over up to 15,000 square kilometers in the middle of the desert and transforms Botswana into a living labyrinth of channels, islands, and flooded areas.

Chinese woman planted trees for decades while sand buried part of her house, received $5,000 from an American in 1999, and helped transform the desert into a forest of 8 million trees in China.

System created to save lives in disasters turned ‘against’ Brazilians overnight: a hacker attack sent out a false alert from Civil Defense with the word “misantropia” that went off on the phones of half the country, even in silent mode, and took down the Cell Broadcast.

NASA captured by satellite an underwater volcano erupting in the Bismarck Sea, in the Pacific, and now scientists are waiting to see if a new island will be born there in front of the cameras, a very rare phenomenon to witness live from space.

The Atacama Desert, the driest place on Earth, was covered in flowers and turned into a colorful carpet with more than 200 species in the phenomenon called “desert bloom,” when atypical rains awaken seeds that had remained dormant in the soil for many years.

In the cold desert of Ladakh, where it hardly rains, engineer Sonam Wangchuk created the ice stupa, a tower that freezes winter water and stores it for irrigating crops in the spring, a simple engineering feat that mimics nature.

For the first time in history, solar and wind energy generated more electricity than natural gas worldwide in a single month, April 2026, a milestone in the energy transition that shows renewable sources taking the lead in the global electric system.
