Fuel Cell integration with off-grid renewable power systems

This informative piece takes a dive into the integration of Fuel Cells within JCE's hybrid system philosophy, and highlights a number of scenarios and the advantages/disadvantages they bring to the overall system.

Power Requirements

Power:180W, Continuous 24Vdc, 24 h/day
Battery:VRLA, 4 days autonomy
System Recharge Time:4 days
Location:Safe Area
Geography:
North Sea

Overall System Philosophy

.

Solution 1:

System completely powered by solar panels and batteries.


Solution 2:

System powered by solar panels, batteries and fuel cells.


Solution 3:

System powered by solar panels, batteries and fuel cells with additional autonomy.

Availability Explanation:

The system availability is the lowest due to the dependence on weather conditions.

The system availability is justified due to the fuel cell offering back-up capacity for the system.

The system availability is justified due to the increased number of fuel cells offering back-up capacity for the system.


Advantages +





Disadvantages -
