Taiwan government thus set up aggressive energy transition goals, which aims to achieve 20% energy supply from renewable energy sources by 2025. Installation capacity of electrochemical energy storage is also targeted to reach 590 MW over the same period, while the green energy industry is expected to develop along with the investment on renewable energy. Due to the intermittent nature of renewable energy sources, energy storage systems are required to stabilize the power grid and increase energy utilization efficiency. According to a report published by Bloomberg New Energy Fund, global stationary energy storage installation capacity is expected to grow exponentially by over 100 times from 2018 to 2040. To capitalize this business opportunity, it is critical to develop our own energy storage technology. Soluble lead flow batteries (SLFBs) are advantageous for their easy modularization structure, low materials cost, high safety, and mature recycle systems; therefore, they are potentially suited to serve as stationary energy storage systems. However, SLFB technology is still under development and very few studies can be found focusing on the modularization and grid utilization of SLFBs. Based on our previous break though on SLFB technology, this research project aims to investigate the modularization and grid-connection capability of SLFBs to facilitate their application to large scale energy storage. There are four research directions we plan to pursue: (1) study of SLFBs in series and in parallel; (2) flow design and reaction tank optimization of SLFBs; (3) modularization and fabrication improvement of SLFBs; (4) grid-connection simulation study of SLFBs. We hope to achieve the goals of cycle life extension, modularization design and fabrication process improvement, and manufacturing and operation cost reduction of SLFBs through this effort. Ultimately, we expect to facilitate commercialization of SLFBs, and in turn to cultivate energy storage industries and promote local production.液流電池;鉛;模組化;儲能;電網;redox flow battery; lead; modularization; energy storage; power grid
