Energy storage is much on the mind of people in the utility industry these days. A decade ago, storing electricity was prohibitively expensive. Of course, a decade ago, solar panels were also expensive, but the cost of both has plummeted in the past 10 years. Tesla is leading the way when it comes to lithium-ion battery storage, but other technologies are gaining ground.
Flow batteries operate by having two electrically charged fluids — one with a negative charge and the other with a positive charge — stored in tanks that are separated by a membrane that allows electrons to pass from one to the other. Just last week, Form Energy, a startup supported by Bill Gates, among others, signed a deal with Great River Energy for a flow battery capable of providing up to 150 hours of energy storage. The technology behind the Form Energy battery is a closely guarded secret but it appears to rely on a solution of water and sulfur, so it is a form of flow battery.
Now PV Magazine reports that German company Schmid Group and Nusaned Investment have joined forces to develop a 3 GWh vanadium redox flow battery production facility in Saudi Arabia. Nusaned is a subsidiary of Saudi Aramco. The consortium is planning to begin manufacturing activities at the new facility in 2021. The products will be sold under the Everflow brand to utility companies, telecom towers, mining sites, remote cities, and offgrid locations.
“The new JV will aim to establish a leadership position in the rapidly developing energy storage market and both companies are fully committed to realizing our joint vision for the project,” says Schmid CEO, Christian Schmid.
