The POSE²IDON consortium existing of 30 companies - 14 industrial companies, 4 shipyards, 6 universities or research institutes, 3 professional associations or consulting companies and 3 classification societies - is to investigate the potential for the commercially effective application of electric ship technology in an about Euro 20 million European Union funded project.
The project POSE²IDON - Power Optimised Ship for Environment with Electric Innovative Designs ON board -, which began in January 2009, consists to provide a working guide on how to improve efficiency and reduce the environmental impact of the combined European commercial shipping fleet and to enhance the electric ship concept so that it can be applied to a wider range of vessels than is currently the case.
The principal barrier to adoption of the electric ship concept in smaller merchant ships is the size of the generating equipment and propulsion motor. The Pose²idon consortium is then focusing on achieving size reduction through the development of new technologies across all aspects of marine electrical engineering. A key element of this will be the application of High Temperature Superconductivity (HTS) technology that will allow for smaller principal electrical components and an increase in efficiency. Additionally, electric auxiliaries, wireless technology and fail safe power distribution will be studied.

Life Cycle Assessment (LCA) has recently gained widespread support as a way of estimating the environmental and societal impact over the lifetime of a ship. The output will normally be a set of indicators, but there is an increasing demand for including other indicators related to safety and economics. An integrated analysis demands that all indicators are weighted with respect to their relative importance in a multi-criteria decision process. However, comparison will not be efficient without a common denominator. In order to facilitate integration of ecodesign (design process to environmentally optimize the design) with risk based design (ship design optimized with regards to safety and accidental costs), this paper proposes a way of monetizing the various indicators related to the environmental footprint, the social external impact and safety. Hence, an integrated model for assessing the safety and environmental performance of a ship in monetary terms is presented in this paper.
