A circular Battery Economy for Community Resilience 

Turning innovation into real-world solutions for a
more resilient Puerto Rico.


Puerto Rico's Unique Opportunity


Puerto Rico is uniquely positioned to demonstrate how retired hybrid electric vehicle batteries can become valuable community assets within a Circular Battery Economy™. This reuse-and-repurposing initiative responds to growing energy resilience needs and an expanding fleet of electrified vehicles while building strong partnerships among industry, universities, government, and local communities.

Renewable Energy Potential

There is enough daily solar energy to meet island electricity needs using panels on < 1% of Puerto Rico’s land.

Energy Resilience

Frequent hurricanes and grid disruptions highlight the need for reliable energy systems.

Energy Storage

Supports renewable energy, improves grid reliability, and provides backup power during outages.

Battery Circularity

Retired batteries can be reused, repurposed, and responsibly recycled.


Building Puerto Rico's First Circular Battery Economy



The Technology and Education Center for Renewable Energy (TECRE) is establishing Puerto Rico's first community-centered Circular Battery Economy™. More than a battery reconditioning program, it is a long-term enterprise designed to strengthen communities through renewable energy, workforce development, education, and entrepreneurship. The figure shows how battery modules move through the Green Zone™, Yellow Zone™, and Red Zone™ - extending battery life before valuable materials are recovered ultimately returned to the OEM battery supply chain.

Turning Retired Batteries into Community Assets


Retired hybrid vehicle batteries can retain significant energy-storage value long after they leave the road. Rather than treating these batteries as waste, TECRE is transforming them into community assets that provide backup power, create skilled jobs, expand educational opportunities, and strengthen Puerto Rico’s energy resilience. This vision was featured in Northeastern University’s Powering Puerto Rico documentary. TECRE successfully repurposed retired Toyota hybrid battery modules into a solar-powered residential energy-storage system that provided backup power to a family in Utuado. This successful demonstration serves as a proof of concept for how retired vehicle batteries can be given a second life while creating lasting value for Puerto Rico’s communities.
