technology seminar - batteryes, storagae, fuel cell and hybrids Fuel cells – the basics • Low temp. (<100 °C) or High temp. (600 to 800 °C) • Efficiencies between 50 and 70% • Can use a multiplicity of fuels: Hydrogen LNG Biogas Ammonia Methanol 8

technology seminar - batteryes, storagae, fuel cell and hybrids Summary • Batteries as energy carrier for ships are limited to short range and limited power applications • Replacing spinning reserve with instantly available power from batteries enables engines to be operated at higher load enhancing overall operational efficiency, reduce emissions and reduce maintenance cost • Fuelcells have interesting features as power convertor. Price development will determine if and when they will be a commercial viable alternative to piston engines. 12
