What You're Seeing

This map displays ARCHES signed partners building California’s hydrogen infrastructure. Recent federal program changes accelerate a shift in focus away from federal programming to enabling an expanding commercial marketplace. Additional Ecosystem partners from our Original RFP and Rolling RFP will be added shortly. 
 

Why These Projects Matter

These ARCHES partners work together as a coordinated system, not isolated projects. By sharing infrastructure and using standardized agreements, they will create the economies of scale and network effects that make hydrogen commercially viable.

First commercial agreements begin Q4 2025, scaling throughout 2026 with greater flexibility and speed.

Join the Growing Ecosystem

ARCHES is actively expanding through our Rolling RFI/RFP process, welcoming hydrogen producers, distributors, and offtakers.
