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.

世界上还有14亿人用不上电，而到2050年，全球电力需求将**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。太阳能和风能的间歇性需要集成储能系统。电力储能对于智能电网和分布式发电的发展至关重要。固定电池、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的电化学技术的几个例子。在液流电池技术中，氧化还原液流电池（RFB）是最新的一种电池技术，由于其固有的安全性、较长的循环寿命以及能量和功率含量的独立缩放，它具有固态电池等其他电池技术所没有的优点。然而，由于其低能量和功率密度以及组件成本低，rfb的商业化一直受到阻碍。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有不断发展的兴趣，该RFB **将从H2O2中产生电力。在这个研发项目中，核心重点将放在一种具有代表性的新型RFB上，该RFB将利用H2O2发电。将进行设计、开发和测试，以确定性能参数（库仑效率和能量效率），并进行分析，以确定离子通过这种新型RFB的多孔膜的转移。以千瓦时为单位储存的能量和以千瓦时为单位输送能量的速率是能量储存的两个重要指标，将在本RFB中进行实验测量。能源储存将在未来能源供应中扮演越来越重要的角色。从长远来看，投资研发这种系统**有可能在安大略省和加拿大节省燃料和减少碳足迹。
