Our technologies play a critical role in the fight against climate change; both in mitigating climate change and helping our world become more resilient to climate impacts. EnerSys views ‘climate technology’ as a product that can reduce CO2 emissions more than the emissions required to produce it. Many of our products meet this definition, and we are energized by their positive worldwide impact.

Our energy storage (batteries) and energy systems allow for more effective and rapid decarbonization by bridging the gap between intermittent renewable energy generation (like wind and solar) and power demand by ensuring seamless connectivity between production and consumption periods.

Our solutions enable customers across the globe to meet their energy and carbon emission reduction goals while providing reliable and affordable energy access. In 2023, EnerSys produced around 13 gigawatt hours of energy storage capacity, which is used to ensure safe, affordable and clean power for industries and people worldwide.

Our products and services enable the widespread adoption of renewable energy, supporting global greenhouse gas emissions reduction goals and helping to slow the impacts of climate change. And, as climate impacts interrupt power supplies, our technology supports communities when they need it most by providing reliable and affordable access to energy.
We invest significant resources into research and development, testing and certification to ensure that our products remain safe for our customers and consumers. As such, we pursue quality management system certifications for the industries in which we operate, including the AS9100 for aerospace, the ISO 13485 for medical devices, the ISO 26262 for Lithium-ion Batteries (LiBs) in Motive Power applications and the TL9000 certification for telecom devices.
