Solutions for a lower sulphur content

Fuel oil

In maritime shipping, heavy fuel oil is still the most commonly used fuel for ship's engines. However, the required sulphur content in fuel of 0.50 % in general and 0.10 % in emission control areas cannot be achieved with common heavy fuel oil. Many shipping companies and charterers choose Marine Gas Oil (MGO), which is lower in sulphur, or an Ultra Low Sulphur Heavy Fuel Oil (ULSHFO).

A conversion of the machinery will also allow ships to use HFO and MGO alternatingly. However, MGO is more expensive than HFO.

Gas-to-Liquids (GtL)

The Federal Maritime and Hydrographic Agency (BSH) operates five ships as research vessel or other kinds of purpose for the government. Those five ships all use GtL by now – Gas-to-Liquids – a fuel that is better for the environment. The fuel is free of sulphur and the emission values regarding nitrogen oxide and particle emission are better than conventional diesel fuels. Several shipping companies operating ferries in island traffic in the North Sea use GtL as fuel for their ships as well.

Methanol, hydrogen, batteries

Other alternative fuels and ways of propulsion such as methanol, biodiesel, hydrogen, batteries or hybrid propulsion systems are not yet a realistic alternative because a comprehensive implementation would mostly fail for reasons of low economic efficiency or limited availability. Although, some of these solutions are already suitable for niche areas.

An alternative to Marine Gas Oil is the use of an exhaust gas cleaning system, a so called scrubber. These units wash out the sulphur compounds using sea water. The installation of scrubbers aboard a ship is expensive and takes up relatively large areas of space thus reducing the available cargo space. You can find the conditions for discharging scrubber waste water in German waters on the website of the Federal Maritime and Hydrographic Agency (BSH).

Liquid Natural Gas (LNG) as fuel

Another solution to comply with the low sulphur content is the use of Liquid Natural Gas (LNG) as fuel. LNG is a natural gas that has been cooled down to -162° degrees Celcius, which keeps it in a liquid condition. The whole machinery system of the ship needs to be set up for LNG usage, which is an expensive conversion for an existing ship. There are also not enough fuel stations in ports yet. On the other hand, burning LNG is a lot cleaner than conventional fuels. Shipping experts expect an increase in LNG fuelled maritime shipping as medium to long-term prognosis.

LNG becomes increasingly important for German-flagged shipping as well. The ferries MS „Helgoland“ der Reederei Cassen Eils and MS „Ostfriesland“ der Reederei AG „Ems“ were the first ships with LNG propulsion under German. In 2020, the BSH-fleet gains its first LNG-fuelled ship the research vessel ATAIR whose main areas of operation will be sea surveying and wreck search. Currently, another ferry and a large container vessel under German flag are undergoing conversion to LNG.
