• Fuel cell has a nonlinear voltage – current relationshipand thus requires power conditioning

• Low voltage in high current leads overdimensioning as system to be dimensioned to withstand with no-loadvoltage

• Lack of ”inertia” need to be compensated by othermeans

• Requires tighter control integration than in traditionalsystems

• Control method (ripple) of power electronics mayinfluence negatively to life time of the fuel cell

Key factors for electric integration

October 25, 2019 Slide 10

Waste heat and excess waterValuable side streams

• 3046 passengers• 1271 crew members• ~650 000 liter water consumed daily• ~100 000 kg fuel oil consumed daily• Estimated cost of water production

by RO ~ 2USD/m3

• 100 000 kg HFO means 460MWh produced electric energy + steam• Fuel Cells would then produce 184 000 liter water/day -> 140kUSD/year• 1/3 of water heated ~12,5MWh/day; possibility to utilize waste heat• Laundry and dishwashing machines use steam• Lot of other steam loads
