Special Issue Information

Dear Colleagues,

The “net zero” targets and increased renewable energy uptake are sustainable only with the accelerated development, commercialization and utilization of next-generation energy storage technologies. Among several storage options, such as pumped-hydro, compressed-air, super capacitors, hydrogen and batteries, the latter are the most preferred in view of their response, portability, scalability, and modularity. While Li-ion batteries have attracted most of the attention to date due to their successful cost reduction in recent years, ongoing safety issues, and the growing need for longer-duration energy storage are shifting interest towards other energy storage technologies. Redox flow batteries are the preferred devices, especially for long-duration and large-scale energy storage duties with low levelized cost of energy. With intense research and development activity sustained over the past couple of decades, redox flow batteries have come of age, and recently, the global market has been taking note of their kilo- and mega-Watt range field deployments. Nevertheless, there are challenges to be addressed to make flow batteries more reliable, economical, and sustainable for future energy storage applications. Low energy density, high cost of raw materials, long-term stability of electrolyte, cell-stack architectures, and integration with renewable energy sources are some of the challenges that need more focus. This Special Issue addresses recent progress and future research directions towards creating a sustainable market for redox flow batteries.

Renewable energy systems are essential for carbon neutrality and energy savings in industrial facilities. Factories use a lot of electrical and thermal energy to manufacture products, but only a small percentage is recycled. Utilizing energy storage systems in industrial facilities is being applied as a way to cut energy costs and reduce carbon emissions. However, lithium-based batteries, which are predominantly used in traditional industries, face challenges in terms of affordability and reliability. Redox flow batteries, on the other hand, offer high power output and reliability, and are economical to manufacture for installations with high capacity. Although redox flow batteries are difficult to use in general electrical systems due to their small volume-to-capacity ratio, they can be easily utilized as energy storage devices in industrial parks or renewable energy parks with relatively little space constraints. In addition, since factories use a lot of heat energy in addition to electricity, utilizing combined heat and power can further reduce heat energy. In this study, we analyzed the cost estimation and economic feasibility of utilizing photovoltaics, redox flow cells, and combined heat and power to save energy in a factory’s energy management system.

Redox flow batteries represent a captivating class of electrochemical energy systems that are gaining prominence in large-scale storage applications. These batteries offer remarkable scalability, flexible operation, extended cycling life, and moderate maintenance costs. The fundamental operation and structure of these batteries revolve around the flow of an electrolyte, which facilitates energy conversion and storage. Notably, the power and energy capacities can be independently designed, allowing for the conversion of chemical energy from input fuel into electricity at working electrodes, resembling the functioning of fuel cells. This work provides a comprehensive overview of the components, advantages, disadvantages, and challenges of redox flow batteries (RFBs). Moreover, it explores various diagnostic techniques employed in analyzing flow batteries. The discussion encompasses the utilization of RFBs for large-scale energy storage applications and summarizes the engineering design aspects related to these batteries. Additionally, this study delves into emerging technologies, applications, and challenges in the realm of redox flow batteries. Full article
