A new standard methodology for assessing the environmental impact of stationary energy storage systems (LCA-SESS)

Lithium-ion batteries (LIB) in stationary energy storage systems (SESS) are a core solution to support the grid in response to the increasing trends for electrification, decentralization and integration of renewables. SESS can be seen as a near-term enabler of the climate agenda in Sweden, and globally.

However, the environmental impact resulting from the use of LIB in SESS has not been broadly studied, and there is a lack of common methodologies and standards for applying replicable life-cycle analyses (LCA) for the specific SESS applications, leading to inconsistent and unreliable results or conclusions.

The aim of this project is to develop, verify and assess a new cradle-to-grave LCA methodology tailored for environmental impact assessment of SESS, including steps tailored to the specific SESS use-stages and end-of-life alternatives (e.g. recycling).

The project aims to provide general recommendations for policy makers towards new SESS LCA standards in the energy storage industry.
