High-Performing, Zero-Emission Hydrogen Coaches & Buses

Transitioning to clean buses and coaches is a challenge for passenger transport operators, regardless of the type of fleet and vehicle they manage: urban or long-distance, public or private. At Symbio, we deploy zero-emission, Hydrogen Fuel Cell solutions that make all the difference for our clients. We decarbonize new or existing fleets, without compromising on operational flexibility and user comfort. 

Turnkey hydrogen bus solutions with an unmatched value proposition. 

Symbio designs, develops and industrializes hydrogen high-performance fuel cell systems combining the ease of use of diesel or Natural Gas vehicles with the zero-emission quality of electric powertrain:

• COMPACTNESS: our latest-generation StackPack^TM 75 product, specifically designed for bus applications, offers twice the power density while being 20% lighter than current market references.
• POWER and EFFICIENCY: our systems are among the most hydrogen-efficient, with a total system efficiency of 53% (based on 18m articulated city bus, running on VECTO Urban duty cycle, at mid-load: 60% passengers).
• COOLING: our systems require 30% less cooling capacity than the average.
• MONITORING: direct access to fuel cell data to optimize operation and enable predictive maintenance as well as a diagnosis in case of breakdown.
• CLIMATE and HEALTH friendly: zero emission of CO2 at use, no noise nuisance.
• WIDE RANGE: buses can run up to 2 consecutive days without refuelling.
• OPTIMIZED UPTIME and OPERATIONAL FLEXIBILITY with fast refuelling in just under 15 minutes.
• MAXIMIZED PASSENGER CAPACITY and THERMAL COMFORT thank to greater on-board energy density.
• EASY INFRASTRUCTURE DEPLOYMENT IN DEPOTS: no need to increase the number of electric charging stations nor to connect to the electricity grid.
