Saudi Arabian Oil Co. (Saudi Aramco) achieved a global milestone by successfully operating a megawatt-scale renewable energy storage system for gas production. It’s the first time an iron-vanadium redox flow battery has been used as a solar energy backup for gas well operations. 
The company said the technology could offer a flexible, cost-effective energy solution across industrial applications. It also helps integrate renewables and supports emissions reduction goals.
The 1 MWh flow battery is installed in Waad Al Shamal, northwest Saudi Arabia. It’s based on Aramco’s patented technology and was developed in collaboration with China-based Rongke Power (RKP), a global leader in flow batteries.
The battery supports up to five gas wells over a 25-year lifespan. It provides a strong alternative to current solar systems, with high efficiency and cost savings. It’s also designed for Saudi Arabia’s extreme climate, ensuring stable performance under harsh weather.
Unlike traditional batteries, flow batteries store energy in liquid electrolytes outside the cell. When pumped into the cell, the electrolyte converts chemical energy into electricity. This design allows frequent charging and discharging with minimal capacity loss.
The system improves fire safety and features a modular structure, making it easier and cheaper to maintain. It also consumes less vanadium and uses the electrolyte more efficiently than other systems.
It operates within a wide temperature range, from -8°C to 60°C, without requiring thermal management. This makes it ideal for isolated, unmanned oil and gas sites, offering scalable, cost-effective energy storage.
Aramco said the project supports its investment focus on renewables and energy efficiency. It’s part of the company’s goal to reach net-zero Scope 1 and 2 emissions for fully owned and operated assets by 2050.
Ali Al-Meshari, Senior Vice President (SVP) of Technology, said the battery marks a major shift for the energy sector. He noted that Aramco currently powers remote wells with solar panels and lead-acid batteries, but the new system offers a more adaptable and resilient storage solution.
