- Aramco commissioned a 1-MW/hour Iron-Vanadium flow battery in Wa’ad Al-Shamal.
- The system was developed with Rongke Power and has a 25-year lifespan.
- It operates efficiently in temperatures from -8°C to 60°C.
- The battery supports Aramco's net-zero emissions goal by 2050.
Introduction
Aramco has commissioned a megawatt-scale renewable energy storage system to power gas production activities, marking the first global deployment of an Iron-Vanadium flow battery as a backup solar power source for gas well operations.
Technology and Development
Located in Wa’ad Al-Shamal, Saudi Arabia, the 1-MW/hour flow battery system is based on Aramco's patented technology, developed in collaboration with Rongke Power. The system is designed to support up to five wells over its 25-year lifespan, offering a robust alternative to existing solar energy solutions.
Performance and Efficiency
The flow battery is engineered to withstand extreme weather conditions, with an operating temperature range of -8°C to 60°C, eliminating the need for thermal management systems. It provides energy independence, can be repeatedly discharged and recharged with minimal capacity loss, and reduces fire risks compared to other battery types.
Environmental Impact
This new technology aligns with Aramco’s focus on renewables investment and energy efficiency, contributing to its ambition to achieve net-zero Scope 1 and Scope 2 greenhouse gas emissions by 2050. The battery offers enhanced electrolyte utilization and reduced vanadium consumption, paving the way for further integration at isolated and unmanned oil and gas sites.
