Hybrid power solutions reduce fuel consumption and emissions. Depending on setup and operational profile, CO2 emissions can be significantly reduced. The hybrid system also allows for completely emission-free periods, which is making a great difference in terms of operational expenditure and sustainability.
Recent developments in battery technology and ship electrii-cation hold signiicant promise for more eficient use of energy, energy recovery and use of renewables. All electric ships and hybrid ships with energy storage in large batteries with optimised power control can signiicantly reduce fuel costs, maintenance and emissions. Additionally, increased ship responsiveness and improved regularity and safety in critical situations are obtained. Power generation units can be smaller or fewer and optimised for a more average (not peak) load, and thereby reducing investment costs.
Batteries can store energy harvested from waste heat recovery, regenerative braking of cranes and renewable energy. Additionally, they can improve propulsion systems based on LNG and other environ-mental friendly fuels and improve the performance of emission abatement technologies. 
Major maritime power system providers are now offering new battery based solutions. More smart BMS control software and more efficiency operation configuration will be developed and installed on the vessels and offshore buildings.
