The Battery War at 55°C in the Desert: How China's Energy Storage Legion Conquered Saudi Arabia?

Created on 12.17
In the afternoon Saudi desert, the temperature is approaching 55 degrees Celsius. Rows of neatly arranged containerized energy storage units stand quietly in the vast yellow sand like soldiers clad in silver armor. Inside them, batteries from China are undergoing the most severe "baking" test.
On the screen of the Saudi National Grid Control Center, an unusually smooth power curve is quietly being generated. This does not come from traditional oil power plants, but from the Bisha battery energy storage project located hundreds of kilometers away in the depths of the desert — it is precisely releasing the "excess sunlight" collected by photovoltaic panels during the day at the peak of electricity consumption at night.
In 2025, Saudi Arabia will enter the top ten in the world for newly installed capacity of new energy storage for the first time. Behind this is an unprecedented explosion of the energy storage market triggered by the "Vision 2030."

New Battlefield

Driving this energy revolution is Saudi Arabia's ambitious "Vision 2030." The core energy goal of this plan is: by 2030, 50% of the country's electricity will come from renewable energy, with a total installed capacity reaching 130 gigawatts.
However, relying on solar and wind energy has a fatal weakness: intermittency and instability. When the sun is shining brightly, there is an excess of electricity, but at night or during calm weather, there may be power outages.
Therefore, the massive energy storage system has become an indispensable "stabilizer" and "power bank" for realizing this vision.
Saudi Arabia has set a clear roadmap for this: to achieve a battery storage capacity of 48 gigawatt-hours by 2030. Progress is rapid, with 26 gigawatt-hours of projects already in the development stage as of November 2024. Furthermore, institutions predict that, based on existing plans, Saudi Arabia will firmly hold the position of the third-largest energy storage market in the world.
This deterministic massive market, born out of top-level design, instantly attracted the attention of global energy giants, and a "battery war" surrounding technology, cost, and adaptability has begun in the desert.

Extreme Challenge

The Middle Eastern desert is a "hell-level" testing ground for energy storage devices. Extreme high temperatures, rampant sandstorms, and high salt mist corrosion each pose a severe threat to the lifespan, safety, and performance of lithium batteries.
At an extreme high temperature of 55℃, the performance of ordinary batteries will sharply decline, lifespan will shorten, and it may even trigger the risk of thermal runaway. Meanwhile, fine dust can infiltrate everywhere, potentially clogging the cooling system and causing equipment to overheat and fail.
Whether these environmental challenges can be overcome will become the "ticket" for entering the competition. Chinese energy storage companies have not chosen to avoid them, but have instead carried out a targeted "extreme technology breakthrough."

China's Plan

The response strategy of Chinese enterprises is: deep customization and hardcore innovation. What they launch is no longer generic products, but special equipment named "Desert Eagle" and "Sand Eagle."
Thermal management is the primary battlefield. Hichain Energy's "Desert Eagle" system, customized for the Saudi project, can reduce the internal temperature of the container by 8-10℃ compared to the outside through a special multi-layer insulation structure design. Jinko Energy has equipped its delivered energy storage projects with a patented step-type liquid cooling system, which can keep the battery temperature steadily below 35℃ even in high external temperatures.
Wind and sand prevention has become a standard capability. The energy storage system cabinet newly launched by Trina Storage uses a C5-level heavy anti-corrosion coating, and the internal modules reach the highest dust and water resistance level of IP67, ensuring safety during sandstorms. Haicheng Energy Storage adopts a fully sealed process for core components and is equipped with an intelligent sand and dust early warning system.
Long lifespan and high safety are the ultimate tests. BYD provides an energy storage system using advanced Cell-to-System technology for its largest grid-side energy storage project (12.5GWh) in Saudi Arabia, aiming to enhance overall efficiency and reliability. Trina Storage's module-level liquid cooling system and reinforced cabinet structure can even offer 2 hours of full cabinet fire resistance.
These customized technical solutions not only allow Chinese batteries to "survive" in the harsh desert but also to "work efficiently," earning the trust of the owners.

Order Battle

Technical strength quickly translates into market share. The Saudi energy storage market witnessed a remarkable "order competition" between 2024 and 2025, with records being repeatedly broken by Chinese companies.
In July 2024, Sungrow Power signed a contract with a Saudi company for a 7.8 GWh energy storage project, setting a record in the Middle East at that time.
In early 2025, BYD achieved a breakthrough by securing a massive order of 12.5 gigawatt-hours from the Saudi Electricity Company (SEC), becoming the first Chinese energy storage company to surpass the 10 gigawatt-hour threshold. With the previously delivered 2.6 gigawatt-hours, the total cooperation volume between BYD and SEC has reached 15.1 gigawatt-hours.
At the same time, CATL won a supply contract of 19 gigawatt-hours in neighboring UAE, demonstrating the dominance of Chinese leading enterprises in the entire Middle East region. HiTHIUM also signed a large-scale project in northern Saudi Arabia with a total scale of 4 gigawatt-hours.
In addition to independent energy storage orders, a more representative example is a series of "benchmark" integrated projects. For instance, the Saudi Red Sea New City project, which features a core energy storage system of 1.3 gigawatt-hours provided by Huawei Digital Energy, is paired with 400 megawatts of photovoltaic power, forming the world's largest off-grid solar energy microgrid, achieving the feat of powering a city with a population of millions entirely with clean energy. The energy storage system of this project received Guinness World Record certification in 2025.
These orders measured in "gigawatt-hours" not only solidify the market position of China's energy storage corps but also test and optimize their "desert survival plan" in practical scenarios.

The Road to the Future

Conquering the desert market is far more than just delivering equipment. Chinese energy storage companies are evolving from simple "product exports" to deeper levels of "technology standards exports" and "ecosystem exports."
In super projects such as the Red Sea New City in Saudi Arabia and NEOM Future City, Chinese companies provide not just batteries, but also integrated solutions that combine photovoltaics, energy storage, energy management, and grid interaction. This transition from a single product supplier to a comprehensive energy system service provider has built a higher competitive barrier.
The deeper opportunity lies in the fact that by participating in the formulation of technical standards for large projects in the Middle East, China's energy storage technology route is expected to influence and even shape industry norms in the region and globally. When the verified Chinese liquid cooling, intelligent string, and long-duration energy storage standards in the desert become models, their global impact will be immeasurable.
As the sun sets in the west, the 488 energy storage units of the Saudi Arabia Bisha energy storage project begin to operate efficiently, converting daytime solar energy into stable and reliable electricity for the night.
This land, which once completely relied on fossil energy, is quietly changing due to the "stabilizers" brought by China's energy storage army. The batteries are not only combating extreme weather in the desert but also laying the foundation for a country's future energy independence.
As the clock ticks for the "2030 Vision," Chinese energy storage companies are winning not only market share in this high-temperature war but also the right to define the discourse of the next generation energy system. Batteries in the desert store not just electricity, but the energy of an era.
