In Richland County, South Carolina, the COMET mass transit system has introduced a new fleet of four buses that operate on hydrogen and electricity in celebration of Earth Day. These zero-emission buses are set to offer a more sustainable and eco-friendly mode of transportation for the community. The buses are designed to be cleaner, quieter, and more efficient compared to traditional diesel-powered buses. Thanks to a substantial grant from the FTA, amounting to nearly three million dollars, COMET was able to invest in these environmentally friendly vehicles. The hydrogen buses are particularly noteworthy for their quick recharge time of just fifteen minutes, making them a practical choice for busy transit schedules. On the other hand, the electric buses, while taking longer to recharge at about two hours, also provide a reliable emission-free option for commuters. The implementation of these new buses is projected to have a significant impact on reducing gas emissions, potentially eliminating up to 135 tons of pollutants per year. Additionally, COMET is committed to evaluating the performance of both types of buses to determine which technology best aligns with the community's requirements. This strategic approach will guide the gradual phasing out of older diesel buses in favor of the more sustainable hydrogen and electric alternatives, showcasing a long-term commitment to environmental consciousness and modern transit solutions.
