This webinar, presented by Gamma Technologies’ own Michael Zagun (Staff Application Engineer, Mobility & System Integration) and Thomas Vevaud (Senior Application Engineer, Reactive Flow Systems), highlights the multi-objective optimization of a fuel-cell powered in-harbor tugboat propulsion under selected duty cycle and weather conditions.
The dynamic and forward-facing multi-physics simulation model integrates a physics-based fuel cell/balance of plant (BOP) model and an electrical-equivalent energy storage (ESS) model offering realistic response dynamics. The optimal control solution, which is based on ECMS utilizes a kinematic backward-facing propulsion system model considering the system dynamics and constraints. The proposed modeling approach exploits the fuel-saving potential of each system design variant and thus offers significant design and workflow improvement.
