With an emphasis on reducing fossil fuel consumption and emissions, major delivery service corporations have begun deploying and operating Class 6 zero emissions delivery vans. Battery electric delivery vans are currently available, but their range is a limitation and doesn't offer flexibility in assigning vehicles to delivery routes. Fuel cell hybrid delivery vans offer a zero emissions solution with extended range and route planning flexibility. In a competitive market, a delivery van design that trades the fuel cell and battery size, performance, and cost is critical to the success and adoption of these zero emissions trucks. This paper outlines a systematic approach using real world operational data and duty cycles to properly size the fuel cell and battery for a zero emissions hybrid delivery van. The approach uses real world GPS data to define routes and duty cycles, along with vehicle powertrain models to assess performance capabilities. The study suggests that a 32 kW fuel cell power system paired with a 49 kWh battery energy storage system and 15 kg of hydrogen storage is a desired option to complete the most demanding parcel and delivery duty cycles.
