Power winches and port cranes with ultracapacitors

Fuel savings and reduced emissions

The maritime industry is already the most efficient form of transportation in terms of shipping goods and conveying passengers. New regulations are in place, however, to further reduce fuel consumption and greenhouse gas emissions for marine vessels.

The answer is electrification and hybridization of propulsion systems. Hybrid ships and boats have a conventional (typically diesel) fossil fuel engine and an electric motor, but when the electric motor is in use, no diesel is burned nor greenhouse gasses released into the atmosphere.

Support for frequency fluctuations

Marine current energy systems suffer from low-frequency (long-term) and high-frequency (short-term) fluctuations. Ultracapacitors can solve frequency fluctuation issues by smoothing the fluctuations in a hybrid systems with batteries.

Why Skeleton's ultracapacitors are ideal for this market

Fuel savings.

Electric motors can be used at low speed locations such as harbors or at other times when high power is not necessary.

Reduced greenhouse gas emissions.

Electric motors emit no greenhouse gasses and significantly reduce the combined emissions of marine vessels.

Lower operating costs.

Ultracapacitor-based energy storage systems have a significantly longer lifetime and are more reliable than traditional li-ion batteries. Ultracapacitors also work together with batteries to by reducing the strain engine starting causes on batteries, thus increasing their lifetime and reliability.
