Wedoany.com Report-Feb 20, Symbio has introduced its StackPack 75, a 75-kW fuel cell system designed for demanding mobility needs. Unveiled on February 20, 2025, this system targets heavy-duty applications such as urban and intercity buses, coaches, light and medium trucks, and off-road equipment like handling and construction machinery. The StackPack 75 delivers tailored power for these intensive uses.
The system stands out for its compact design, with a volume of 268 liters and a weight of 200 kilograms. This ensures maximum payload, extended range, and straightforward integration into vehicles. It operates at a high temperature of 85°C, enhancing heat dissipation and reducing the need for large cooling systems. Consequently, the cooling system’s size and fan power decrease, aiding vehicle integration and conserving energy.
Flexibility is another key feature. The StackPack 75 offers modularity, allowing two or more units to be combined in a single vehicle to meet specific power demands. This adaptability ensures it aligns with various technical and operational requirements across different applications.
Symbio’s technology balances performance and cost-effectiveness across ten critical dimensions. This comprehensive approach optimizes the total cost of ownership throughout a vehicle’s lifecycle. By avoiding oversizing, the system achieves efficient performance tailored to each use case, supporting practical and sustainable solutions.
Production of the StackPack 75 will take place at Symbio’s SymphonHy gigafactory, located in Europe. This facility, the largest dedicated to hydrogen fuel cell development and production on the continent, is equipped for large-scale manufacturing. The initiative has received backing from France Relance and France 2030 under the Hy2Tech Important Project of Common European Interest (IPCEI) hydrogen program. This support aims to advance high-performance, competitive technologies for zero-emission mobility.
Jean-Michel Billaut, a Symbio executive, stated: “The StackPack 75 reflects our commitment to delivering efficient and adaptable solutions for heavy-duty mobility.” The system’s design prioritizes integration ease and operational efficiency, positioning it as a viable option for sustainable transport needs.
The launch underscores Symbio’s role in advancing hydrogen-based technologies. By focusing on durability and performance, the StackPack 75 addresses the practical challenges of intensive mobility while supporting broader environmental goals. Its production readiness at SymphonHy ensures scalability to meet growing demand in the sector.
