Energy storage can provide economical and environmental benefits in the maritime industry. This has been clearly demonstrated by the recent developments within automotive, marine and renewable markets. The ongoing development of battery technology is expected to enable significant improvements in energy-density and cost compared to the currently available technology, which will be necessary for cost-effective utilization of energy storage systems. Fast and economic adoption of new energy storage technologies, requires a wide knowledge base and flexible tools for design and system optimization. In this project the partners has explored a range of new energy storage technologies to be able to evaluate these for further commercial use. The resulting energy storage system may include both advanced electrochemical batteries and other hybrid technologies and will over time increase the energy density and increase the power cycling capabilities extensively. Reduced weight, volume and cost and increased safety will be other benefits. A range of new chemical and electrostatic cell samples has been tested and characterized by Sintef. The results indicates that there is still some years before we see new battery technologies available in the market. Improvement of existing technologies will continue and secure more dense, safe and cost efficient technologies every year. Li-ion capacitors has shown promising results. Test results from the projects shows a significant improvement in energy density for these devices. The project has developed new control algorithms and new control topologies for different combinations of energy storage technologies. Full scale testing of inverter and control systems with new Li-ion cells and batteries has been executed with good results and will be introduced as commercial concepts.

The project results has verified the use of Li-ion hybrid capacitor units for commercial use. These can be used in combinations with other energy storage devices. New control algorithms has been developed and tested and will be further used in commercial applications with a number of combinations of energy storage devices. New battery chemistries have been explored and tested and gives us a better understanding and planning of the future commercial potential with more dense, safe and cost efficient energy storage technology.

Energy storage can provide enhanced economic and environmental performance in several sectors. This has been clearly demonstrated by the recent developments within automotive, marine, and power grid applications. Wärtsilä is currently developing technology for power distribution and system integration in hybrid or purely battery powered ships for low- or zero emission operation. However, the rapid ongoing development of battery technology is expected to enable significant improvements in power- and energy-density compared to the currently available technology, which will be necessary for cost-effective utilization of energy storage for reducing emissions in many applications. Fast and economic adoption of new battery technologies, and integration of different energy storage technologies in the same system, requires a wide knowledge base and flexible tools for design and system optimization. In this project, Wärtsilä and the partners will utilize the potential of emerging energy storage technologies to develop a new generation of compact energy storage systems for high power applications. The resulting energy storage system may include both advanced electrochemical batteries and Li-ion hybrid capacitors or other hybrid battery/capacitor technologies and will increase present energy capacity with at least a factor of 3-5 and increase the power cycling capabilities extensively in a normal ship application. Reduced weight, volume and cost will be other benefits. With the huge new development in energy density and power and cycling capabilities, the total solution will open new market areas and increase the market opportunities as the cost/performance ratio will be reduced significantly. The introduction of the new technology can start early twenties like we see the progress today. The project will be executed together with Sintef Energy/M&C and Haugaland Kraft Nett and 2 international co-partners within the field of new energy storage devices.
