Saudi Aramco has launched the world’s first Iron-Vanadium flow battery system to power natural gas operations using renewable energy. The 1 MWh flow battery, developed with Rongke Power, stores energy in liquid electrolytes, allowing repeated charging with minimal capacity loss, providing backup solar power and greater energy independence for gas wells.
Aramco’s new Iron-Vanadium flow battery system reduces fire risks, is cost-effective, and supports variable power needs for up to five gas wells over 25 years. Designed for Saudi Arabia’s extreme climate, it operates between -8°C and 60°C without thermal management. This innovation advances renewable energy use and emissions reduction in gas operations.
Aramco’s senior VP Ali A. Al-Meshari called the new flow battery system a breakthrough for the oil and gas industry, offering a flexible, sustainable alternative to traditional lead-acid batteries for powering remote gas wells. Developed with Rongke Power, the partnership began in 2023 to explore vanadium redox flow battery (VRFB) solutions. Aramco says this innovation supports its goal of achieving net-zero Scope 1 and 2 emissions by 2050
