ELECTROCHEMICAL ENERGY STORAGE FOR GREEN GRIDS: STATUS AND CHALLENGES
Growing concerns over the environmental consequences of burning fossil fuels and their resource constrains, along with the increasing world energy consumption, have spurred great interests in renewable energy from sources such as wind and solar. However, the power from these intermittent sources is constantly varied, making quite challenging for its use and dispatch through the aging electrical grid. One effective way to smooth out the intermittency is to employ electrical energy storage. Among the potential technologies are electrochemical energy storage (EES) technologies or batteries that are capable of storing a large quantity of electricity and release it according to demands. There exit a number of technologies that have either demonstrated or been interested for the stationary applications. There however remain challenges for the current EES technologies to meet the performance and cost matrices for broad market penetration. As such there have been growing interests and R&D activities in advancing EES technologies. This paper offers an overview on varied technologies, in particular batteries, and discusses the status, challenges and research needs, with focus in the US.
