Electrochemical Energy Storage: Chemicals and/or Batteries

Electrochemical systems are a type of a chemical system, with characteristics that make them ideal for several important technologies, including electrochemical energy storage devices such as batteries, with which we are all familiar. On a larger scale demanded by grid-level applications, batteries that work well in a laptop computer may be uneconomical. Thus the emergence of renewables, where storage will become an increasingly vital component of a robust technology, has created opportunities for alternative batteries and alternative means of storage. We have on-going research in battery systems and in an electrofuel process, where electricity is converted into a liquid fuel. The electrofuel process couples an electrolysis system to a bioreactor that exploits a chemolithoautrophic bacterium to convert CO2 into fuels. We discuss the operation and prospects of the electrofuels process, and we provide a very brief overview of some battery related research, focusing on Li-ion positive electrode materials.
