Canada has set a goal to become net zero by 2050, and decarbonizing its energy grid will be crucial. Renewable energy sources like hydropower are important, but they can be affected by climate change and variability. To address this, large-scale energy storage systems are needed. Pumped hydro storage systems are the most popular, but they require specific geographic conditions and have environmental concerns. Aqueous redox flow batteries, on the other hand, store energy in water-based solutions and can last for decades. They are also scalable, cost-effective, and safe. These batteries can store and release energy for years and are suitable for small and large-scale projects. A large-scale aqueous redox flow battery built in China can power approximately 58,000 homes for 12 hours. However, the main limitation is cost, as commercial batteries currently rely on expensive materials. Researchers are working on using cheaper, more abundant organic materials, but their lifespan and stability are still being improved. Continued investment in research and development is necessary to overcome these challenges and unlock the potential of aqueous redox flow batteries, which could become a key component in the global transition to renewable energy.
Water-based batteries could play a crucial role in Canada’s emission-free future by 2050, and this is how
