Stationary Storage Technologies: Part I, Emerging Technology Review

Stationary Storage Technologies: Part I, Emerging Technology Review

The world is undergoing an immense transition in one of the most key aspects governing our lives. It is in the generation, availability and use of energy which supports all dimensions of our existence. Food production, processing and delivery, infrastructure development, clothing industry, transportation, healthcare and any other activity crucial for our sustenance depends on energy. Over time we have become used to depending on fossil fuels for providing us this key supporting ingredient. It is this core enabler, which is undergoing transition. This transition has been made possible, in part due to the development of advanced technologies for energy storage and conversion. In this series of 4 reports, we attempt to cover all the major technologies which are either currently commercially available or those which are in the final development stages and will be commercially manufactured at scale in the next 3-5 years. All technologies for energy storage and conversion are constantly evolving and improving in performance owing to the ongoing efforts of the global academic and industrial community.

In the current report which is the 2nd in this series of reports, we cover all the electrochemical technologies (except Li-ion and Advanced lead acid) which are of interest for stationary storage applications. These applications can range from small home backup systems to large grid storage installations for frequency regulation, industrial UPS systems and long duration storage of renewable energy.

We wish that through this report we are able to provide specific and to-the-point information to a wide range of audience who are interested in learning about these new technologies. The review is prepared keeping in mind that the readers may be from very different backgrounds and we hope that the concepts and information presented will help all decisions makers from industry as well as from the government.
