Stationary Energy Storage

Norway Installs First Vanadium Redox Flow Battery

17 March 2023

The global energy landscape is going through a major transformation with the increasing demand for reliable and sustainable power solutions. The rise in stationary energy storage systems is a crucial aspect of this transition. The global stationary energy storage market is projected to reach $233.9 billion by 2031 from $28.0 billion in 2021, growing at a CAGR of 23.4% during the forecast period 2022-2031. Norway is leading the charge with its innovative solutions. The country has recently installed its first vanadium redox flow battery, marking a significant milestone in the advancement of energy storage technology. 

Bryte Batteries, a local company in Norway, installed a 5 kW/25 kWh vanadium redox flow battery system at the Sluppen commercial district in Trondheim. The battery was supplied by Pinflow and is optimized by Bryte using its energy management system platform. The system is primarily used for peak shaving and flexibility markets. The project was partially funded by Innovation Norway and the Norwegian University of Science and Technology to evaluate its use in the flexibility market.

1. What is a Stationary Energy Storage System?

A stationary energy storage system refers to an electrical storage system that is fixed in place and is not intended for mobility. The system stores energy from various sources, such as solar panels, wind turbines, or the grid, and releases it as needed to meet demand. Stationary energy storage systems play a crucial role in the transition to renewable energy sources, as they provide a means of storing excess energy generated during periods of low demand for use during periods of high demand.

2. What is the Role of Vanadium Redox Flow Batteries?

Vanadium redox flow batteries (VRFBs) are a type of flow battery that uses two liquid electrolytes, one positive and one negative, separated by a membrane. The electrolytes are stored in external tanks and pumped through the battery cell to generate electricity. This design provides several advantages compared to traditional batteries, including a longer lifespan, faster response time, and higher energy density. VRFBs are particularly well suited for stationary energy storage applications, as they can store and release large amounts of energy over extended periods of time. They also have the ability to scale up their storage capacity by increasing the size of the external tanks. This makes VRFBs an attractive solution for grid-scale energy storage, as they can help balance energy demand and supply and improve the overall stability of the grid.

3. What is the Future of the Market?

The future of the stationary energy storage market is expected to be highly dynamic, with a significant growth rate in the coming years. The growing adoption of renewable energy sources such as wind and solar power, along with the growing demand for backup power and grid stability, is driving the growth of the stationary energy storage market. The market is expected to witness an increase in the adoption of advanced energy storage technologies, such as lithium-ion batteries and flow batteries, including vanadium redox flow batteries (VRFBs). These technologies provide more efficient, reliable, and cost-effective energy storage solutions compared to traditional technologies. In addition, the growth of the electric vehicle (EV) market is expected to have a positive impact on the stationary energy storage market, as EV charging infrastructure will require more energy storage solutions. Governments around the world are also supporting the growth of the stationary energy storage market through various policies and incentives aimed at promoting the adoption of renewable energy sources and energy-efficient technologies.
