Doctoral dissertation, Harvard University.http://dissertations.umi.com/gsas.harvard:11262http://nrs.harvard.edu/urn-3:HUL.InstRepos:11744432In this work I describe various approaches to electrochemical energy storage at the grid-scale. Chapter 1 provides an introduction to energy storage and an overview of the history and development of flow batteries. Chapter 2 describes work on the hydrogen-chlorine regenerative fuel cell, detailing its development and the record-breaking performance of the device. Chapter 3 dives into catalyst materials for such a fuel cell, focusing on ruthenium oxide based alloys to be used as chlorine redox catalysts. Chapter 4 introduces and details the development of a performance model for a hydrogen-bromine cell. Chapter 5 delves into the more recent work I have done, switching to applications of quinone chemistries in flow batteries. It focuses on the pairing of one particular quinone (2,7-anthraquinone disulfonic acid) with bromine, and highlights the promising performance characteristics of a device based on this type of chemistry.en-USMaterials ScienceEnergyEngineeringFlow batteryGrid-scale energy storageHalogensModelingQuinonesThesis or Dissertation2014-02-25
