“…In previous research, the authors developed a control system for the FCS-MH system management throughout a model-based approach and tested the dynamic behavior in several conditions [29]. However, a proper control is mandatory to answer to fast load variations, to avoid stressing PEM Fuel Cells, which represent the propulsion system onboard, integrated with electrical batteries.…”

The present paper aims to analyse the thermal coupling of PEM fuel cells fed by hydrogen, stored in metal hydride tanks for maritime applications, considering the first Italian zero emissions ship with hydrogen PEM fuel cells propulsion (ZEUS), launched in 2022. A dynamic model is developed, and the integrated propulsion system is analysed in different operative conditions, considering the transitory that can be experimented during navigation (i.e., from harbour to cruise speed). The behaviour of the fuel cells in dynamic conditions is investigated, considering two different control systems, based on PID and Model Predictive Control approaches.

“…Their off-design and transient behavior is investigated by the point of view of their safe and reliable operation as well as performance improvement, degradation minimization, and control improvement [17][18][19][20]. On the other hand, PEM-based systems have been mostly addressed for mobile applications [21][22][23][24], and in few cases for stationary use [25].…”

Dynamic Modeling of a PEM Fuel Cell Power Plant for Flexibility Optimization and Grid Support

The transition toward high shares of non-programmable renewable energy sources in the power grid requires an increase in the grid flexibility to guarantee grid reliability and stability. This work, developed within the EU project Grasshopper, identifies hydrogen Fuel Cell (FC) power plants, based on low temperature PEM cells, as a source of flexibility for the power grid. A dynamic numerical model of the flexible FC system is developed and tested against experimental data from a 100-kW pilot plant, built within the Grasshopper project. The model is then applied to assess the flexible performance of a 1 MW system in order to optimize the scale-up of the pilot plant to the MW-size. Simulations of load-following operation show the flexibility of the plant, which can ramp up and down with a ramp rate depending only on an externally imposed limit. Warm-up simulations allow proposing solutions to limit the warm-up time. Of main importance are the minimization of the water inventory in the system and the construction of a compact system, which minimizes the distance between the components.
