About Viridi

Shaping a Sustainable Future.


Viridi deploys fail-safe lithium-ion battery technology into applications that fossil fuel energy sources have historically dominated. 

Revolutionizing the way energy is used and stored with commercial-scale lithium-ion-based energy storage systems certified for installation in occupied spaces. 


A Renewable Energy Center of Excellence.

Viridi’s 42-acre campus home was built in 1923 for General Motors. We are resuscitating this historic space in order to bring green jobs and workforce training opportunities to one of the nation’s most impoverished zip codes while also serving as a model of how adaptive reuse projects can spur the economy and revitalize communities.

Our Mission

Viridi is committed to using the power of business to address the interconnected systems of economic inequality, environmental degradation, and climate change.
