This Small Business Innovation Research Phase II project will develop the underlying technology behind a highly efficient energy storage system that can provide reliable, dispatchable power from intermittent renewable energy sources such as wind and solar. This technology is based on a novel hydrogen/chlorine chemistry embodied in a regenerative fuel cell architecture that can address MW-scale applications. This project will develop a better scientific understanding of important technological barriers to commercial implementation of this technology including developing an insight into parametric behavior through both experimentation and modeling, improving reactant mass transport at the chlorine electrode, and eliminating parasitic shunt currents in multi-cell module architectures. Sustainable Innovations, LLC, will work with Harvard University to develop an 8-cell, laboratory scale electrochemical module having a round-trip efficiency of over 80% with design features that optimize mass transport and reduce shunt currents and will evaluate the performance of this module through a series of parametric and durability tests. This research will culminate in the development and demonstration of a 100-Watt integrated system and the development of a 135 kW system concept that will serve as a critical building block for future commercialization efforts.Concern about the increasing level of greenhouse gases is intensifying the global interest in better ways to harness renewables such as solar, wind, and hydroelectric power. Renewable power applications have experienced significant growth as a result of this belief and also technological advancements that have reduced their cost and increased their efficiency. Utility privatization and deregulation have opened the market for innovative power technologies, and some consumers have elected to use renewables even when they are more expensive than grid power. But renewables can't always generate power on demand because they depend upon favorable natural conditions, such as the presence of sunlight or wind. The development of cost effective, efficient energy storage systems that could create dispatchable power from inherently intermittent renewables may enable the widespread use of these technologies. Various technologies, particularly batteries, have been implemented for applications requiring energy storage, but conventional batteries have significant efficiency, cycle life and life cycle cost limitations which reduce the overall cost effectiveness of renewable installations. New technologies, such as hydrogen/halogen regenerative fuel cells with improved efficiency, cycle life and cost are needed to add value and utility to intermittent renewables creating technical and economic drivers for widespread commercial deployment and global electrification.

该小型企业创新研究第二阶段项目将开发高效储能系统背后的基础技术，该系统可以从风能和太阳能等间歇性可再生能源中提供可靠的可调度电力。 这项技术是基于一种新的氢/氯化学体现在再生燃料电池架构，可以解决兆瓦级的应用。 该项目将对该技术商业实施的重要技术障碍有更好的科学了解，包括通过实验和建模深入了解参数行为，改善氯电极处的反应物质量传输，以及消除多电池模块中的寄生分流电流架构。Sustainable Innovations，LLC将与哈佛大学合作开发一种8电池实验室规模的电化学模块，其往返效率超过80%，具有优化质量传输和减少分流电流的设计功能，并将通过一系列参数和耐久性测试评估该模块的性能。 这项研究将最终开发和演示一个100瓦的集成系统和一个135千瓦的系统概念的发展，将作为未来商业化努力的关键构件。对温室气体水平不断上升的关注正在加强全球对更好地利用太阳能，风能和水力发电等可再生能源的兴趣。 由于这种信念以及降低成本和提高效率的技术进步，可再生能源应用经历了显着增长。 公用事业私有化和放松管制为创新的电力技术打开了市场，一些消费者选择使用可再生能源，即使它们比电网电力更昂贵。 但可再生能源并不总是按需发电，因为它们依赖于有利的自然条件，如阳光或风力的存在。 开发具有成本效益的、高效的能量存储系统，可以从固有的间歇性可再生能源中产生可调度的电力，这可以使这些技术得到广泛使用。 已经针对需要能量存储的应用实施了各种技术，特别是电池，但是常规电池具有显著的效率、循环寿命和寿命周期成本限制，这降低了可再生装置的总体成本效益。 需要新技术，如提高效率、循环寿命和成本的氢/卤素再生燃料电池，为间歇性可再生能源增加价值和效用，为广泛的商业部署和全球电气化创造技术和经济驱动力。
