Development of EU battery storage - Part 131 Aug 2019 10:13

EU policymakers are currently considering a regulatory proposal for sustainability requirements that must be met by all batteries manufactured and/or deployed in the EU.
Energy storage technologies are essential for both sustainable mobility and the integration of increasing shares of renewable energy sources into the energy system while maintaining an efficient and secure operation of the grid. Different policy measures are needed to promote the research, development, and deployment of all energy storage technologies, including batteries: R&D funding must be directed towards this challenge and the energy market design must create a level playing field for all technologies.
For batteries in particular, it is important also to develop requirements on ethical sourcing of raw materials as well as strict sustainability requirements (e.g. touching on durability, low carbon footprint, reusability, recyclability of batteries, etc).
For this reason EASE supports efforts by EU policymakers to bolster the manufacturing and deployment of safe and sustainable battery technologies across the EU and believes that a proposal for sustainability requirements could have a positive impact on the industry, provided that several key points are carefully considered:
1. Mobile and Stationary Storage Devices Work Differently
Mobility and stationary applications of batteries differ significantly; therefore, if the two are regulated together, they should have clearly differentiated categories with specific requirements for each category. In particular, minimum performance requirements (e.g. energy density, durability, capacity, etc) cannot be set for all batteries regardless of application. Batteries for back-up applications will need a limited number of cycles (i.e. In the range of 100 cycles), batteries for solar PV integration will need daily cycling (i.e. in the range of 3,000-6,000 cycles) and EVs normally need a weekly cycle (i.e. in the range 500-1,000 cycles in their lifetime).
