Development of a redox flow battery using aluminum and hydrogen peroxide

世界上有14亿人口没有用上电，而到2050年，全球对电力的需求将翻一番。可再生能源占美国发电量的12%。**在减少碳排放的必要性的推动下，全球太阳能和风能装机容量分别以**每年60%和20%的速度增长。太阳能和风能能源的间歇性要求**集成的储能系统。电能存储对于智能电网和分布式发电的发展至关重要。固定式电池、可充电金属-空气电池、超级电容器、再生燃料电池和液流电池是适用于**EES的几种电化学技术。在液流电池技术中，氧化还原液流电池(RFB)是最新的一种电池，由于其固有的安全性、长的循环寿命以及**能量和功率含量的**独立调节，因此具有一些其他电池技术(如固态电池)无法比拟的优点。然而，由于其低能量和功率密度以及**组件的成本，阻碍了RFB的商业化。VIROX Technologies Inc.**(该项目的工业合作伙伴)对开发新型的、具有成本效益的RFB的兴趣与日俱增，这种RFB**将从过氧化氢中产生电力。在这个研发项目中，核心焦点将是一种**具有代表性的新型RFB，它将从过氧化氢中产生电力。将进行设计、开发和测试**以确定性能参数(库仑效率和能源效率)，并将进行分析以确定离子通过这种新型RFB的多孔膜的传输。以千瓦时为单位存储的能量**和以千瓦为单位的能量传输速率是能量存储**的两个重要度量数字，并将对此RFB进行实验测量。能源储存将在**输送未来能源方面发挥越来越重要的作用。从长远来看，对这种系统的研究和开发投资**在安大略省和加拿大都有节省燃料和减少碳足迹的潜力。

1.4 billion of world's population do not have access to electricity, while the demand for electricity will be**doubled by 2050 worldwide. Renewable sources constitute 12% of electricity generated in the United States.**Driven by the necessity to reduce carbon emission, global solar and wind installed capacities are growing at**rates of 60% and 20% per year, respectively. The intermittent nature of solar and wind energy sources demands**integrated energy storage systems. Electricity energy storage (EES) is vital for the smart grid and distributed**power generation development. Stationary batteries, rechargeable metal-air batteries, supercapacitors,**regenerative fuel cells, and flow batteries are several examples of electrochemical technologies suitable for**EES. In flow battery technology, Redox flow battery (RFB) is the newest one that has some favorable features**over other battery technologies, e.g. solid state batteries, due to their inherent safety, long cycle life, and the**independent scaling of energy and power content. However, because of their low energy and power density and**the cost of components the commercialization of RFBs has been hindered. VIROX Technologies Inc.**(industrial partner of this project) has an evolving interest in the development of novel, cost effective RFB that**will produce electricity form H2O2. In this research and development project, the core focus will be on a**representative novel RFB that will create electricity from H2O2. Design, development, and testing will be done**to determine the performance parameters (coulombic efficiency and energy efficiency) and analysis will be**done to determine ion transfer through the porous membrane of this novel RFB. The amount of energy stored**in kWh and the rate at which this energy can be delivered in kW are 2 important figures of metric in energy**storage and will be measured experimentally for this RFB. Energy storage will play an increasingly vital role in**delivering the energies of tomorrow. In the long run, investment in research and development of such system**has the potential for fuel savings and carbon footprint reductions in Ontario as well as in Canada.
