Opportunities for all-electric ships in smart energy systems

Greenhouse gas emissions have been a major concern in recent years where maritime sector has a significant contribution as well as in energy usage. Since maritime technology has begun to replace mechanical propulsion by electric propulsion, it gives the opportunity to replace conventional fuels with alternative ones such as electric batteries and renewable energy source. Today’s researches and practice have shown that the future energy systems are developing as a smart energy systems using energy produce by the renewable energy source replacing conventional ones, aiming to reduce emissions to minimum. Electric ships can also find their place in smart energy systems, through integration of intermittent renewable energy sources, and play an important role in smart grid concept integrating ships and ports, reducing its negative impact on the environment. This work presents opportunities for the electric ships in future energy system seeking replacement of conventional fuels with alternative ones in order to reduce global pollution. Comparison of the electric ships with the conventional ones in the field of operational, financial and social aspects is also provided within this work. On the example of the Dubrovnik region, aiming to achieve 100% electricity production from the renewables till 2050, is show that the all-electric ships could be good option for the integration of renewables in smart energy systems through shore-side power concept.
