ACCIONA Energía’s 1 MW Second-Life BESS Assessed by DNV to Meet EU Circularity Standards

(IN BRIEF) DNV is collaborating with ACCIONA Energía to assess a 1 MW second-life BESS prototype—built from repurposed Silence e-scooter batteries—against EU standards, including the Batteries Regulation (EU 2023/1542). In partnership with integrator Beeplanet, ACCIONA Energía’s pilot system aims to extend battery lifecycles and reduce environmental impact. DNV’s evaluation covers first-life performance, repurposing processes, testing methods, electrical design, thermal management, and safety concepts. Santiago Blanco of DNV emphasizes that this project exemplifies the alignment of energy-transition efforts with circular-economy and sustainability goals.

(PRESS RELEASE) BÆRUM, 9-Jul-2025 — /EuropaWire/ — DNV has partnered with Madrid-based ACCIONA Energía to evaluate second-life battery energy storage systems (BESS) against European regulatory standards and industry benchmarks. ACCIONA Energía—the world’s largest fully renewable energy company with no fossil-fuel legacy—is investigating how to repurpose batteries from its Silence electric scooter fleet in compliance with the EU Batteries Regulation (EU 2023/1542), which enshrines circular-economy principles for electronic devices.

Working alongside Beeplanet, a specialist in second-life BESS integration, ACCIONA Energía has built a 1 MW prototype stationary storage installation using these reclaimed scooter batteries. DNV’s scope of work encompasses a thorough review of the prototype’s engineering design and overall second-life strategy. This includes analyzing the batteries’ first-life performance, the repurposing workflow, and the testing protocols, as well as scrutinizing the system’s electrical architecture, thermal management approach, and safety framework in relation to applicable EU guidelines.

“By advising on ACCIONA Energía’s Second Life BESS initiative, we help companies advance the energy transition while adhering to the UN Sustainable Development Goals and European circularity mandates—protecting people, assets, and the environment,” stated Santiago Blanco, Executive Vice President & Regional Director for Southern Europe, Middle East, Latin America, and Africa, Energy Systems at DNV. “Our technical assessment ensures the safe, responsible reuse of electric-vehicle batteries, demonstrating how circular-economy models can bolster system resilience and environmental stewardship in the energy sector.
