“Green ships” – perspective and development

There is a wide field of technologies like low- sulphur fuels, internal engine modifications (such as water injection and exhaust gas recirculation), humid air motors, selective catalytic reduction, duel-fuel engines that are contributing to air pollution reduction caused by ships. With growing concern for environmental air pollution, there is also a growing interest for the application of renewable energy technologies on ships. These technologies are not new to the world, but when considering the ship as the place of the installation this raises the question regarding the ship overall design and the impact on fuel consumption and air pollution. In this paper the concepts of wind and solar energy production on ships are presented. The overview of the experimental ships that are harvesting the renewable energy is given in the text. Also, the new concept of wind and solar combined in the form of rigid sail is presented. The concept of medium voltage direct current distribution system application is presented in the paper. Traditional electrical distribution system on ships is low voltage AC system. This concept is very different from renewable energy technology but also provides fuel saving thus providing less air pollutants.
