Calistoga, CA — In a town where wildfire threats are a constant concern, Calistoga has taken a bold step toward energy resilience by installing a groundbreaking clean energy system that combines hydrogen fuel cells and batteries to power the city during emergencies.
Situated on the northern edge of Napa Valley, Calistoga has faced the harsh realities of wildfire in recent years. The scars of the 2020 fire remain visible on nearby hillsides, a reminder of the evacuation that swept through the entire town. Even more haunting is the memory of the 2017 Tubbs Fire, which ignited just miles from downtown and claimed 22 lives in the region.
Traditionally, when wildfire risk required shutting off utility transmission lines to prevent sparking, Calistoga relied on a bank of diesel generators housed in a popular recreation area. While effective in keeping the lights on, these generators emitted thick diesel exhaust and produced loud noise, disrupting public use of community spaces.
That has now changed. The town has installed a first-of-its-kind hybrid system that marries hydrogen fuel cells with battery storage, capable of powering Calistoga for approximately two days without interruption. The new technology not only provides cleaner backup power but also presents a potential model for future support of the electric grid beyond emergency scenarios.
During final tests conducted in late May, residents gathered near the system’s location—a site that includes a dog park, ball fields, community garden, and bike trail—to witness a quieter, cleaner alternative to diesel power. Lisa Gift, a city council member and local resident, expressed optimism about the transition.
“Continuing to depend on fossil fuels was simply not sustainable,” Gift said. “That’s what excited me about this. It’s a clean and reliable energy solution that ensures the safety and resilience of our community.”
As climate change intensifies wildfire frequency and severity in California, Calistoga’s initiative stands as a testament to how small communities can lead on innovative climate adaptation strategies. The project also serves as a proving ground for hydrogen fuel cell technology, which experts believe could play a larger role in future clean energy systems.
With this hybrid system now operational, Calistoga has not only enhanced its emergency preparedness but has also taken a significant step toward a more sustainable and resilient energy future.
