As a maritime expert with a focus on ship propulsion and fuel systems, I can provide a comprehensive overview of the types of fuel used in ships. The maritime industry is a complex and dynamic sector, where fuel is a critical component for the operation of ships. The choice of fuel is influenced by various factors including environmental regulations, cost, availability, and the type of ship.
Heavy Fuel Oil (HFO) is traditionally the most common fuel used in large ocean-going vessels, particularly in the main engines of cargo ships and tankers. It is a byproduct of the refining process of crude oil and is known for its high energy density and low cost. However, HFO is also known for its high sulfur content, which can lead to significant emissions of sulfur oxides (SOx) when burned.
Low Sulur Fuel Oil (LSFO) is a cleaner alternative to HFO. It has a lower sulfur content, which helps to reduce SOx emissions. The International Maritime Organization (IMO) has set regulations that require ships to use LSFO in certain designated Emission Control Areas (ECAs), such as the Baltic Sea, the North Sea, and the coastal waters of North America. LSFO is more expensive than HFO, and its use is becoming more widespread as environmental regulations tighten.
Diesel Oil, also known as Marine Gas Oil (MGO) or Distillate Fuel Oil, is another type of fuel used in ships, particularly in smaller vessels and in auxiliary engines. Diesel oil is a lighter, cleaner-burning fuel compared to HFO and LSFO. It has a lower sulfur content and produces fewer emissions. However, it is also more expensive than the heavier oils.
In addition to these traditional fuels, there is a growing interest in alternative fuels due to increasing environmental concerns and the need to reduce greenhouse gas emissions. Alternative fuels include:
- Liquefied Natural Gas (LNG): This is becoming a popular choice for newbuild ships, especially in the cruise and ferry sectors. LNG is cleaner-burning than traditional marine fuels and emits less SOx and particulate matter. It also has the potential to reduce greenhouse gas emissions.
- Biofuels: These are fuels derived from organic material, such as waste oils or agricultural products. Biofuels can be used as a blend with traditional fuels or in their pure form, depending on the engine design.
- Hydrogen and Fuel Cells: Hydrogen can be used in fuel cells to generate electricity for propulsion. This technology is still in the early stages of development for maritime applications but holds promise for zero-emission shipping.
- Wind-Assisted Propulsion: While not a fuel, wind-assisted technologies such as sails and kites can reduce the amount of fuel needed by providing additional propulsion power.
The choice of fuel is not only influenced by environmental considerations but also by the operational profile of the ship, the availability of fuel at ports, and the economic factors. Ships must also be equipped with the appropriate fuel storage and handling systems, which can be costly to install and maintain.
In conclusion, the fuel used in ships is a multifaceted decision that involves balancing environmental regulations, operational requirements, and economic considerations. As the maritime industry continues to evolve, we can expect to see a shift towards cleaner and more sustainable fuel options.

Most ships produce their electricity using diesel engines. Others use gas turbine engines to generate electricity. Still others use a combination of the two. Diesel engines use heavy fuel oil (--HFO--) while gas turbine engines use marine gas oil (--MGO--), which is similar to the fuel used in jet airplanes.
