Transitioning to 100% zero-emission buses (ZEBs) is an unprecedented challenge for transit agencies. Analy is one of a few experts in ZEBs who can help. For over a decade, she has brought hydrogen fuel cell and battery-powered buses to city streets.

Driven to improve air quality, Analy became passionate about environmental sustainability as uncontrolled growth in the cities of her native country, Guatemala, turned blue skies to gray. After moving to California, Analy found like-minded colleagues in UC Irvine’s Advanced Power & Energy PhD Program where her ZEB research included the first hydrogen fuel cell pilot programs in Orange County.

Her research and publications have influenced policymakers and ZEB regulations. A model she developed for her thesis optimizing ZEB phasing is now being used by our transit team. This model, ZEBDecide, helps transit agencies determine their unique mix of battery and hydrogen fuel cell buses based on the terrain, routes, and infrastructure.

As a consultant, her expertise in the systems, operations, and planning impacts related to ZEBs makes her invaluable to clients. As a mother, Analy vows to continue advocating for zero-emission vehicles to help keep skies blue for her daughter.
