Energy storage from exhausted bus batteries
Tauron decided to give a second life to batteries from electric buses and started working on prototype energy storage.
The Second Life ESS project aims to reuse lithium-ion cells previously used in urban transport vehicles. Although batteries are no longer sufficient to power vehicles over time, they can still function as stationary energy storage for many years to come. As a result, instead of being disposed of, they will be reused.
- Warehouses built with the use of cells will constitute an important element of the intelligent electricity infrastructure. They combine energy production in local prosumer micro-sources or small photovoltaic sources with its storage and delivery to the end user. Importantly, local, dispersed battery energy storage may be an element stabilizing the operation of power grids, especially in low voltage grids, where the share of energy from unstable RES sources is constantly growing - explains Jerzy Topolski, Vice President of TAURON Polska Energia for asset management. - Battery electric energy storage (EES) may support the development of electromobility and energy clusters and affect the quality of electricity supplied - adds Vice President Topolski.
As part of the Second Life project, Solaris will provide batteries with a total energy capacity of 160 kWh for the construction of the warehouse. Previously, the batteries were used in one of the PKM Jaworzno electric buses.
The project is carried out with the support of a consortium of Solaris Bus & Coach Sp. z o.o. and Impact Clean Power Technology S.A.
