# German Startup Repurposes E-Scooter Batteries for Industrial Energy Storage EDENenergy converts discarded e-mobility batteries into sustainable 70 kWh industrial storage systems. - **Source:** [InsideEVs](https://insideevs.com) - **Published:** 2026-11-04 - **Topic:** [climate](https://brifing.si/c/climate) - **Original article:** - **On Brifing:** https://brifing.si/s/97547219-44f5-4566-bfc8-8c35adb2f614 ## Repurposing E-Mobility Waste German startup EDENenergy is tackling the growing problem of discarded e-bike and e-scooter batteries by integrating them into industrial energy storage systems. By giving these used power units a second life, the company aims to reduce landfill waste while providing affordable storage solutions for businesses that currently lack the capacity to store renewable energy. ## Impressive Battery Capacity Retention Founded by former researchers from the Fraunhofer Institute for Solar Energy Systems ISE, the startup tested 112 used e-scooter battery modules. While initial expectations suggested the units would retain 80% of their original capacity, testing revealed that most modules actually maintained 90%, proving that discarded batteries remain highly functional for stationary storage applications. ## First Commercial Storage Milestone In mid-October, the company successfully delivered its first commercial 70-kilowatt-hour battery system to a customer. This initial product is specifically designed for medium-sized regional companies that already operate photovoltaic solar panels but currently lack the necessary infrastructure to store the energy generated during peak sunlight hours for later use. ## Operational Stability and Maintenance The system provides a stable environment for the batteries, eliminating the vibrations and extreme temperature fluctuations experienced during their previous use in e-scooters. The startup monitors each module remotely and allows for individual module replacement without powering down the entire system, ensuring continuous operation for energy-sensitive clients who cannot afford any downtime. ## Scaling Future Storage Capacity Looking ahead, the startup is developing a larger-capacity system capable of holding up to 300 kWh. This ambitious project will utilize approximately 500 second-life e-scooter modules. By scaling up, the company hopes to divert significantly more hazardous electronic waste from landfills while providing robust energy solutions for larger industrial energy storage requirements. ## Overcoming Technical Integration Barriers A primary challenge for the company is the current reliance on large suppliers providing uniform battery types. To expand, the team must adapt connector interfaces, battery management systems, and communication protocols to accommodate diverse battery types from various manufacturers. This technical flexibility is essential for handling the wide variety of batteries found in e-bikes. ## End-of-Life Recycling Strategy The company maintains a clear commitment to sustainability even after the second-life batteries eventually degrade. Once the modules reach the end of their functional lifespan in the storage system, they will be sent to specialized recycling facilities. There, the components will be dismantled and the materials recovered for reuse in future manufacturing processes. ## Impact on Energy Markets By bridging the gap between discarded consumer electronics and industrial energy needs, EDENenergy demonstrates a circular economy model for battery technology. This approach provides a practical alternative to costly grid upgrades for businesses. As the startup grows, its ability to standardize diverse battery inputs will determine its long-term viability in the competitive energy sector. ## Sources covering this story - https://insideevs.com/news/814389/e-bike-e-scooter-second-life-batteries-energy-storage/ — --- _Summary written by Brifing from the original reporting.
