dangerous mining practices, as well as accompanying environmental destruction. The cobalt used in lithium-ion electrodes is mined in facilities driven by wage-slavery and inhumane working conditions [4]. Furthermore, we have no mechanism of recycling lithium-ion batteries [9]. Further usage of these materials which endanger miners and devastate the environment when there are viable alternatives is completely unconscionable for a university that considers itself a leader in sustainable innovation. The campus’ need for increased energy storage is an inevitable truth. Required to advance our renewable energy generation, lower costs, and support expanding construction, the construction of a new battery at UMass is undeniable. However, the evident problems with large- scale lithium-ion batteries make it a poor solution to this problem. Instead, we suggest the implementation of a vanadium redox flow battery to manage future energy storage at UMass. 4. Solution Technology Explainer UMass currently estimates a need for a 3.5MWh energy storage system over the next ten years [10]. This may seem like a large demand, but commercial grade VRFBs have been shown to have an energy storage capacity of up to 800MWh [11]. This large storage ability is due to its design. The scalability of VRFBs will allow them to meet any increase in energy storage demand across campus over the next 10 years. This scalability is due to the high energy density of the electrolytes used in a VRFB. VRFBs are so energy-dense due to the use of highly water-soluble electrolytes. Energy density is defined as the ability to store charge per unit volume. A VRFB has a theoretical energy density of 332 Wh L-1, which is substantially higher than other large scale batteries such as lithium- ion, which has a theoretical energy density of 223 Wh L-1 [13]. This increased energy density occurs because as a This means a VRFB is a better investment for UMass than a different but comparably sized battery because it The battery storage team believes vanadium redox flow batteries (VRFBs) are the best way to store energy on our ever-growing campus due to its scalability, energy storage capacity, lifespan, and safety. The average VRFB is designed to have 2 storage tanks that hold the positive and negative electrolytes and a system of pipes and pumps which enable the electrolyte to flow from the tanks to the battery cells and back. Multiple cells can be stacked and integrated into the battery system. The number of stacks defines the charging and discharging power while the size of the tanks defines the energy storage capacity [12]. So when more stacks are implemented into the system, or if the size of the electrolyte tank is increased, the VRFB can store more energy. VRFB discharges, reduction occurs at the cathode and oxidation occurs at the anode. Simultaneously, electrons are transferred through an external circuit and proton ions diffuse across the membrane. [13]. Due to the highly water-soluble electrolytes used in VRFBs, more electrons are transferred across the membrane, allowing for a higher energy density.PDF Image | Power of Implementing a Vanadium Redox Flow Battery UMass
