The solution has already been successfully implemented in projects such as Lia Daycare and Holmlia School in Oslo, demonstrating its technical and economic viability in different building types. Because it relies on widely available technologies and repurposed electric vehicle batteries, the approach can be replicated in schools, public buildings, social housing and neighbourhood energy communities. As the number of electric vehicle batteries reaching the end of their first life continues to grow, second-life battery storage offers a scalable and sustainable solution for accelerating the transition to renewable and locally managed energy systems.
