heal.generalDescription |
It is undeniable that the most crucial challenge of our generation is to solve the climate crisis and the human activities related pathogenicities that trigger the latter. International shipping emits 2 to 3 percent of global greenhouse gases (GHG) emissions, transporting close to 80 percent of global trade by volume. To curb the emissions from shipping, the IMO has agreed on an ambition to reduce GHG emissions from shipping by at least 50 percent by 2050. To reach this goal and to make the transition to full decarbonisation possible, commercially viable zero emission vessels must start entering the global fleet by 2030, with their numbers to be radically scaled up through the upcoming decades. This will require both developing the vessels as well as the future energy supply chain, which can only be done through close collaboration and deliberate collective action between the maritime industry, the energy sector, the financial sector, governments, academic researchers and the relevant IGOs. In that context, shipping’s decarbonisation can be the engine that drives green development across the world. The falling costs of net zero carbon energy technologies make the production of sustainable alternative sources of energy increasingly competitive. This will translate through the supply chain into increased demand for zero emission techniques and applications. It could also be an important point of leverage for change across other hard-to-abate sectors, thus accelerating the broader energy transition. Under those circumstances and with little time left before climate change becomes irreversible there has emerged a new opportunity and feasible solution for the shipping industry. That is the battery sourced ships industry. Electric propulsion as a concept exists since the 1880s but until recently industry focused only at the much cheaper and most effective in large scale, options of internal combustion engines propulsion. As a result the subject of battery sourced all electric ships can be further studied and evolved rapidly. At the same time batteries technology seems to be in the process of great evolution with regarding new novelties being announced continuously capturing the industry and public interest and provoking a domino effect on the electrification of every aspect of human activities, including maritime which has always been a pioneer when it comes to new technologies and embracing the future. In the light of those facts, this thesis focuses on the energy study in general, the multiple factors to be considered about electric propulsion and last but not least the batteries technology and installation on-board. All pieces of information that is accumulated shall be applied onto three similar twin – hull hybrid electric ferries. Those concept vessels differ in size, being 33 m, 26 m and 19 m accordingly with subsequent variations in energy loads, electric needs and capabilities. |

heal.abstract |
The purpose of this dissertation is mainly to gather and clarify pieces of knowledge, empirical experience and tangible data regarding the emerging project of marine electrification and unimpeded transition to a more viable future. Relevant rules and regulations that are already established by governments, society classifications and other major organisations are summarised as they set the framework in which marine electrification is taking place. Of course they are not static and are yet to be evolved significantly as this initiative is still in its infancy with most of existing expertise coming from navy and pioneering companies from Norway. Then it is considered appropriate to present some fundamentals on the subject of design of marine energy systems. That includes a vast variety of elements such as electric load balance analysis, electric distribution grid, short circuits et cetera. Subsequently, as the essential basis is set the study concentrates on the ground zero of this subject, the electric propulsion, hybrid or battery sourced. The mechanism of the idea is simple but there are multiple obstacles to overcome in order to dethrone the dominant internal combustion engine propulsion option. The term that is going to dominate maritime soon is the All Electric Ship in which every function is based on electro – mechanic energy transforming. Perhaps the greatest challenge regarding electrification, if it is to be characterized green, is the evolution of battery technology. That is the reason a major chapter of this thesis is to describe some of the potential forthcoming state-of-the-art batteries that are possibly applicable to marine projects and could be the solution to extended energy autonomy need. A posteriori there is a rudimentary and simplistic application of the accumulated theory on three all electric battery sourced catamaran ferries which are designed in the context of a project by ELCAT – GEGET, as an attempt to fully understand the relevant content. In that conjuncture, there are additionally presented fragments of information about the potentials of solar energy on-board and interconnection with shore electric grid. |
