The shipping industry is responsible for approx. 3% of global CO2 emissions. The IMO has set a target to reduce them by 40% by 2030. Efficiency gains and options to easily integrate zero-emission energy sources into the ship’s energy system must be achieved to reach that goal. A key element is the conversion of on-board power systems to direct current (DC). Modern AC shipboard grids contain numerous power converters for efficient part-load operation of engines. Alternative energy sources such as fuel cells, batteries or photovoltaics are based on DC as well. Coupling all these components in a DC grid avoids the numerous conversion losses of an AC grid. To integrate such a meshed DC grid on a wide variety of ship types, numerous issues need to be investigated. An insight into two research projects is given. Conceptual questions concerning operating voltages, grounding and protection concepts, parallel operation of converters and batteries, power flow control and grid control as well as the grid structure of medium and low voltage grids are investigated experimentally and simulatively. To enable cost-effective applicability to many ship types, the power system is modularized with as many common parts as possible to account for different requirements. The regulatory framework is already being taken into account in the research project. The design of the energy system will be subject to an overall system optimization, which determines a cost-optimal operation and structure of the energy system.
