The electric car market in Europe it is growing rapidly. This means that more and more battery-powered models are coming on the road. With the increase in the presence of these cars on the road, more and more people are wondering what will happen to the accumulators once they reach the end of their useful life on the cars. Surely one way is recycling. From the point of view of sustainability, the reuse of accumulator elements represents a fundamental step in creating a circular economy for electric vehicle batteries.
However, as we all know, the batteries, if still in good condition, can be reused in other areas, perhaps in the storage systems. In this way it is possible to give a second life to the batteries and extend their use. With the second life of the batteries, a new and interesting market.
A report from Circular Energy Storage predicts that the second-life battery market could reach $ 3 billion by 2025. However, this is a lower estimate compared to the 4.2 billion dollars estimated in 2018 as the report showed that the accumulators have proved to be longer-lasting than previously estimated. In fact, there are few batteries that have completed their life cycle on cars to date. According to the report, the prices of a “second life” battery will be between 40 or 100 dollars per kWh.
As this new market begins to take shape, several car manufacturers have already launched a number of sod projects related to battery reuse.
Nissan, for example, aims to become carbon neutral in 2050. To achieve this goal, among other things, it is also focusing on the reuse of batteries. The Japanese manufacturer, from this point of view, has an advantage over other brands in as much as the first generation Leaf has already made its debut in 2010. Therefore, the Japanese manufacturer can already boast over 500,000 electric cars in circulation and a good experience in the second life sector. Among the projects he is carrying out, we recall the one with Enel which led to the use of the Leaf batteries as storage systems for the power plant in Melilla, Spain.
Mercedes, for its part, has signed an agreement with Moment Energy for the reuse of batteries as storage systems. We cannot fail to mention the partnership with Batteryloop. This company, in fact, has announced that it will use the discarded batteries from Mercedes cars to create three BLESS III storage systems of 2.8 MW of power each.
BMW too is focusing on second life. For example, the German brand used discarded batteries from its electric cars in storage systems inside a wind farm in Leipzig, Germany. Audi also looks favorably on this sector and has signed an agreement with the Indian Nunam for the reuse of e-tron accumulators in electric rickshaws.
Pure Polestar intends to work on second life. Currently, all of its batteries still circulate in cars. When they reach the end of their life, taking advantage of Volvo’s service network, the accumulators will be sent to special centers where they will be recycled or reused.
To allow the market for second-life batteries to grow properly, however, it is necessary create standards to be respected that today are not yet there.
