Lewis County Transit in Washington has become the first transit agency in the state to introduce hydrogen fuel cell buses. These buses, part of the Pacific NW Hydrogen Hub, underwent testing and are set to enter service soon. The U.S. Department of Energy is conducting a review of potential environmental impacts of hydrogen projects, emphasizing the importance of green hydrogen as a clean energy solution. The Northwest hub, receiving substantial federal funding, envisions projects including hydrogen production facilities, distribution pipelines, and fueling stations for trucks and buses. By using green hydrogen, the region aims to reduce 1.7 million metric tons of CO2 emissions yearly. Green hydrogen, produced using renewable sources like wind or solar power, emits no greenhouse gases when used as fuel. Despite challenges like high renewable energy prices, the Pacific Northwest Hydrogen Hub represents a significant step towards decarbonizing transportation and energy-intensive industries.
