Exploring the Future of Green Transportation: Hydrogen Fuel Cell Buses

King County Metro, a global leader in sustainable transit, is embarking on a pilot project to explore the integration of up to four hydrogen fuel cell buses into its fleet as early as 2026. These buses, which emit only water vapor, offer an extended range and provide a potential solution to reduce local air pollution and combat climate change.

As a public transit agency committed to achieving a 100% zero-emission fleet, King County Metro believes that the addition of hydrogen fuel cell buses could complement its existing battery-electric and trolley buses. This pilot project aims to determine the performance and feasibility of hydrogen fuel cell technology in real-world transit operations.

Michelle Allison, the General Manager of King County Metro, expressed the agency’s dedication to leading the way towards a zero-emissions future. By collaborating with public entities and encouraging the development of innovative technologies, King County Metro aims to share its progress and knowledge with the broader community.

Having already implemented diesel-hybrid buses in 2004 and retired its last diesel-only buses in 2020, King County Metro has proven expertise in managing fleets with advanced technologies. The hydrogen fuel cell bus pilot project presents an exciting opportunity for current and future Metro employees to gain valuable knowledge and skills.

While battery-electric buses have limitations in terms of range, especially in cold weather, hydrogen fuel cell buses offer the potential to travel up to 300 miles. This extended range is particularly promising for all-day, high-frequency routes.

King County Metro’s commitment to sustainability extends beyond its transit operations. Its battery-electric buses and charging infrastructure serve as a model for other agencies and private contractors seeking to adopt green transportation solutions. Furthermore, sustainability is deeply integrated into the agency’s planning for future facilities, exemplified by the Interim Bus Base project.

Recognized by the Federal Transit Administration as the nation’s most equitable agency in tackling climate change, King County Metro is dedicated to making a positive impact both locally and globally. The agency’s continued efforts to explore and embrace cutting-edge technologies like hydrogen fuel cell buses highlight its commitment to a cleaner and greener future for public transportation.
