Aramco has achieved a global first by commissioning a megawatt-scale renewable energy storage system designed to support gas production operations. This innovative deployment marks the first use of an Iron-Vanadium (Fe/V) flow battery as a backup power source for solar-powered gas wells.

Installed in Wa鈥檃d Al-Shamal in western Saudi Arabia, the 1-megawatt-hour flow battery system is based on Aramco鈥檚 proprietary technology and developed in collaboration with Rongke Power, a leading global manufacturer of flow batteries. The system is designed to serve up to five wells during its expected 25-year lifespan. It offers a resilient, cost-effective alternative to conventional solar storage systems, with the added ability to manage fluctuating power demands efficiently.

What sets this flow battery apart is its robust performance in extreme temperatures鈥攅ngineered specifically for Saudi Arabia鈥檚 hot climate. Unlike traditional vanadium batteries, this system operates effectively in a wide temperature range from -8掳C to 60掳C without the need for thermal management systems.

鈥淭his pioneering system represents a major advancement in renewable energy storage for the oil and gas sector,鈥� said Ali A. Al-Meshari, Aramco鈥檚 senior vice president of technology oversight and coordination. 鈥淲hile many of our remote gas wells are powered by solar panels connected to lead-acid batteries, our new flow battery technology provides a more flexible and scalable solution for a wide array of industrial applications.鈥�

Flow batteries store energy in liquid electrolytes, which are housed separately from the battery cells. When pumped into the cell, the electrolytes convert chemical energy into electricity. This design not only allows for repeated cycling with minimal degradation but also reduces fire risk and simplifies maintenance thanks to its modular construction.

Aramco鈥檚 Fe/V flow battery enhances electrolyte efficiency and uses less vanadium compared to existing systems. In line with the company鈥檚 broader sustainability strategy, this deployment underscores Aramco鈥檚 commitment to investing in renewables and improving energy efficiency. The system supports Aramco鈥檚 goal of achieving net-zero Scope 1 and Scope 2 greenhouse gas emissions across its wholly owned and operated assets by 2050.

The successful commissioning of this storage solution opens new opportunities for integrating similar systems at remote or unmanned oil and gas facilities. It delivers a reliable, adaptable energy source that meets the unique challenges of off-grid operations without incurring significant additional costs.

This innovation reflects Aramco鈥檚 broader vision to develop and deploy cutting-edge technologies that advance energy sustainability while maintaining operational excellence.
