Here below is the comparative information provi- ded by the Aentron company. Costs At the current state of technology, the costs of electrical solutions for boats are still considera- ble and might discourage those who have already installed a heat engine, unless they have a strong environmental awareness or simply need to re- place the old engine. On the other hand, the com- parison is different if an electric system is fitted as the first installation directly by the shipyard, because in this case some simplifications and savings, such as for instance the elimination of tanks, pipes and pumps or the lower weights involved, make the electric system immediately more advantageous. In any case, rather than just the starting costs, which are higher for the electric system, we need to compare the costs involved in the entire life cycle of the two propulsion systems, and in the following decades such a comparison favours eco-friendly motors because of the lower requi - red ordinary and extraordinary maintenance. Environmental advantages aside, to get an idea of the costs, the solution that we have hypothesi- Maintenance nessuna Usable capacity 100% Winter storage facile Nominal capacity 5 kWh Cycles 2500 -4000 Theoretical storage capacity 29 kWh Efficiency module (DC) 95% Low battery when it is at 95% Warranty 8-10 anni Usable capacity 24,7 kWh Price (2019) € 8.500 Maintenance rimboccare acido Usable capacity 30%-40% Winter storage facile Nominal capacity 5 kWh Cycles 800-1500 Theoretical storage capacity 16 kWh Efficiency module (DC) 75% Low battery when it is at 65% Warranty 2-3 anni Usable capacity 8,7 kWh Price (2019) € 4000 On top Elektra, the first fully electric ferry.
