King County Metro

King County Metro plans to trial hydrogen fuel cell buses to evaluate their suitability as an alternative to battery-electric buses for overcoming range and reliability limitations.

Systems used to store energy from renewable sources to ensure continuous operation of the biorefinery.

Buses that use hydrogen fuel cells to generate electricity, which then powers the vehicle.

A localized grid with defined boundaries that acts as a single controllable system, capable of operating connected to or independently from the main grid.
