Iron-Vanadium (Fe/V) flow batteries were used in the first megawatt (MW)-scale renewable energy storage system by Aramco, one of the top integrated energy and chemicals businesses in the world, to store solar electricity for natural gas well operations.

Located near Wa’ad Al-Shamal, western Saudi Arabia, the 1-MW/hour flow battery system is intended to sustain up to five wells over a 25-year period.

This solution is anticipated to be both cost-effective and efficient, according to the company. It is built to withstand Saudi Arabia’s high temperatures and can function at its best in most severe weather situations.

Using Aramco’s unique technology, the battery system was created in collaboration with Rongke Power (RKP), a world leader in flow batteries.

The organization anticipates that this solution will be efficient and cost-effective. It can perform optimally in the most extreme weather conditions and is designed to endure Saudi Arabia’s high heat.

The battery system was developed in partnership with Rongke Power (RKP), a global leader in flow batteries, utilizing Aramco’s exclusive technology.

Ali A. Al-Meshari, Senior Vice President of Technology Oversight and Coordination at Aramco, stated, “The innovative flow battery system developed by Aramco’s researchers is a breakthrough for the oil and gas industry.” “Aramco already uses solar panels coupled to lead-acid battery systems to power a lot of remote gas wells, but our innovative flow battery technology provides a versatile solution for a range of renewable energy storage needs, making it a desirable choice for a number of industrial applications. This is only one instance of how Aramco is creating and implementing cutting-edge technologies to improve and lower emissions throughout its operations,” he continued.

Separate from battery cells, flow batteries store energy in liquid electrolytes, which are then pumped into the cell to transform chemical energy into electrical energy. Flow batteries offer energy independence as well as the ability to be repeatedly discharged and recharged with little loss of capacity. Compared to other battery types, they also lower the risk of fire, and their modular architecture makes maintenance simpler and less expensive.
