Join host Bill Derasmo as he chats with Dr. Majid Keshavarz, chief technology officer at EnerVenue. They trace the evolution of nickel‑hydrogen batteries from their NASA origins in the 1970s — proven on missions like Hubble, the ISS, and Mars — to today’s grid applications. Tune in to learn how this inherently safe chemistry delivers decades‑long service life, high cycle counts, and recyclable materials for long‑duration, grid‑scale storage.
