  • eBESS Power is an advanced battery energy storage technology company built on more than five decades of pioneering work in renewable energy. The company develops and deploys proprietary battery energy storage systems engineered for energy resilience in austere, grid-constrained, and mission-critical environments. eBESS was incorporated in 2026 as a Philippine-Japan joint venture.

  • Chief Technology Officer Masato Shirakata holds fourteen foundational battery patents, including the original architectures used in the Nissan Leaf and Toyota electric vehicles. His work at NEC in Japan established the proprietary chemistry that eBESS now manufactures under joint venture with FES, Fine Eco Solution.

  • Proven and operating. The EV Energizing Center microgrid in Las Pinas, Metro Manila has been running on the eBESS system since March 2025. The first prototype batteries have been successfully assembled at the on-site manufacturing facility using nano laser welding equipment supplied by the Japan JV partner. This is not a lab experiment. It is a live installation.

  • The proprietary chemistry is inherently non-flammable, charges faster, lasts longer, and does not depend on the cobalt, nickel, or foreign lithium supply chains that expose lithium ion systems to Foreign Entity of Concern restrictions under United States federal funding rules. chemistry is inherently non-flammable, charges faster, lasts longer, and does not depend on the cobalt, nickel, or foreign lithium supply chains that expose lithium ion systems to Foreign Entity of Concern restrictions under United States federal funding rules.
