Second-life EV batteries pilot projects for circular energy storage

Otón Peñuelas

Co-Founder & CTO at Battwoo

Madrid, Spain

About

Battwoo is seeking partners for collaborative pilot projects under RIV Circular focused on the reuse of electric vehicle batteries in stationary energy storage applications.

We aim to develop and demonstrate second‑life Battery Energy Storage Systems (BESS) in real industrial or grid‑connected environments, addressing safety, performance, durability and circularity aspects at TRL 6–8.

We are interested in collaborating with:

  • Industrial or energy end‑users willing to host pilot installations

  • Research and technology organisations for validation, testing and lifecycle assessment

  • Technology providers (BMS, EMS, diagnostics, digital tools) complementary to second‑life batteries

Battwoo can provide battery systems and integration capabilities, and generate real operational data to support scalable circular energy solutions.
