Zero Emission Bus
Transforming transportation from A to ZEB
Zero emission buses (ZEB) are an effective and efficient way for communities to reduce their carbon footprint. By implementing zero emission buses and transit system electrification, we can combat climate change, improve air quality, and provide a stable infrastructure that is less reliant on fossil fuels and fluctuating energy costs.
Having worked on over 200 sustainable transportation projects, we bring a unique combination of expertise in zero emission bus infrastructure planning and design, route and energy analysis, and available funding opportunity knowledge. Our team can be your trusted advisor—helping you plan for and deploy your zero emission solutions.
We look at the holistic needs for each transit agency and work closely with you to align the necessary zero emission bus components. The goal? For each agency to be operationally and financially successful. We can produce transition plans, help implement battery electric charging infrastructure, and design hydrogen fueling stations and facilities.
Our team is committed to bringing technology to the forefront. Through project work, industry speaking engagements, and published articles, we deliver thought leadership and innovative solutions.
Relying on active industry association memberships and committee participation, we’re transforming transportation—one zero emission bus fleet at a time.
ZEVDecide™
We use ZEVDecide™, a planning tool composed of multiple modules, to provide solutions tailored to our clients’ needs. Using ZEVDecide™, we can predict the performance of battery electric buses (BEBs) and hydrogen fuel cell electric buses (HFCEBs) by route and operating block. We can project total fuel demand, determine charging schedules, and access fueling station recommendations and power requirements. The tool allows for cost optimization, determining the ideal ratio of BEB and HFCEB in a fleet while minimizing ownership costs. Learn MoreHydrogen Fuel Cell Electric Bus
Implementing HFCEBs requires special attention to the production, storage, and transmission of hydrogen. With our diverse background in energy, water, infrastructure, buildings, environmental services, and mobility services, our in-house experts examine macro and micro aspects of the hydrogen value chain. We’re dedicated to assessing and developing the safe design and operations of hydrogen, and we bring design, maintenance, and safety expertise—while providing a seamless interface to your team.Battery Electric Bus
Among the first to plan and implement electrification projects, our experts combine their background in energy, infrastructure, buildings, and mobility with our innovative modeling approach to provide holistic project development for BEB implementation. We start with a detailed assessment of current conditions and create a tailored transition plan that meets current and future needs. Each solution considers engineering details, infrastructure upgrades, operational constraints, costs, and phasing timelines while prioritizing service.Transition Plans and Infrastructure Planning and Design
No two transit agencies are alike, so no two transition plans can be the same. We’ve prepared over 20 ZEB transition plans for agencies, delivered over 500 operations and maintenance facilities, and planned and designed the charging and hydrogen infrastructure requirements at new and existing facilities, including power needs for on-site and en route charging and hydrogen refueling stations. Most importantly? Our clients’ needs are at the center of every solution we design.Our People
