Battery storage guidance note 3: Design, construction and maintenance
This publication captures learning and experience from battery storage construction projects, with special emphasis on ensuring the safety of such projects to people and environment.
Based on industry interviews and available literature, this Battery storage guidance note 3 covers a large range of issues that have caused, or can potentially cause, issues during battery storage projects during design, construction, commissioning, or maintenance, including site selection, using containerised solutions, construction, maintenance, and decommissioning. It shares experience to help others to avoid some of the pitfalls that have affected previous projects, helping to avoid safety issues and project delays.
This publication should be read in conjunction with the two other guidance notes in this series, published by the EI.
Using second life electric vehicle batteries for static energy storage
The publication aims to set out the issues related to the use of ‘second-life’ batteries for stationary energy storage capacity. The predicted growth of the electric vehicle (EV) industry is anticipated to result in large numbers of batteries becoming available whose capacity has degraded to the point where they are not competitive to use in EVs, but which may well still have sufficient capacity for use in stationary storage, as an alternative to new batteries. The intention is to provide understanding of the issues, identify gaps in knowledge, and where appropriate suggest ‘next steps’.
This guidance outlines the various approaches that can be taken to repurpose used EV batteries for grid-scale electricity storage, as well as the uncertainties and other issues that should be considered by operators.
