Tanker ships, along with container ships and bulk carriers, are some of the biggest contributors to the shipping industry's carbon footprint. They are powered by fossil fuels, which significantly contribute to the warming atmosphere and shifting climate patterns. The type of fuel used by tanker ships varies depending on the vessel, with some using diesel and others, heavy fuel oil (HFO). Heavy fuel oil is highly polluting, causing respiratory diseases and acid rain, and is currently consumed by the global shipping fleet at a rate of around 4 million barrels per day. However, there is a push for the shipping industry to transition to cleaner fuels and technologies, such as liquefied natural gas, hydrogen fuel cells, batteries, and other alternatives, to reduce emissions and mitigate the environmental impact of tanker ships.

What You'll Learn
Tanker ships use heavy fuel oil, which is highly polluting
Tanker ships, along with other large vessels, use heavy fuel oil (HFO) to generate power and propel themselves across the ocean. HFO is a highly polluting fuel source that is responsible for causing respiratory diseases and is a component of acid rain, which damages vegetation and wildlife. The sulphur in HFO also contributes to the warming atmosphere and shifting climate patterns.
The shipping industry is a major contributor to the world economy, moving about 90% of globally traded goods. However, it is also a significant contributor to the shipping industry's carbon footprint. The large container ships that are used to transport goods burn fossil fuels, emitting cancer and asthma-causing pollutants equivalent to that of 50 million cars in a year. The low-grade bunker fuel used by these ships contains up to 2,000 times the amount of sulphur compared to diesel fuel used in automobiles.
In recognition of the environmental impact of the shipping industry, the International Maritime Organization (IMO) has implemented regulations to reduce pollution. For example, the IMO has announced a global sulphur cap on marine fuel emissions, limiting the sulphur content in marine fuels to 0.50%. Shipowners are also encouraged to make the switch to lower-sulphur fuels, such as marine gas oil, or install "scrubbers" to strip out sulphur emissions.
While some companies are investing in pilot projects that use renewable fuels and cleaner technologies, there is still widespread reluctance to adopt meaningful change. The high cost of cleaner fuels and the lack of regulation in international shipping and aviation emissions contribute to the slow progress in reducing the environmental impact of the shipping industry.

Marine gas oil is a lower-sulphur alternative to heavy fuel oil
Marine gas oil (MGO) is an ultra-low-sulphur fuel that is considered a lower-sulphur alternative to heavy fuel oil (HFO). HFO is a popular fuel choice for ships because it is inexpensive and high in energy. However, it also has a high emission of sulphur oxide, which has serious environmental and health impacts.
To address this issue, the International Maritime Organization (IMO) has implemented regulations to limit sulphur emissions from ships, encouraging the use of alternative low-sulphur fuels like MGO. MGO is a distillate fuel that has been through a refining process, and it is expected to be in high demand due to its environmental advantages over HFO.
However, MGO also has some disadvantages, including uncertainty about the stability of the fuel and the need for special management due to its low viscosity. It is also expected to be relatively expensive compared to other fuels. Despite these challenges, the shipping industry is exploring alternative fuels and technologies to reduce emissions and meet sustainability goals.
The transition to cleaner fuels like MGO is particularly important for large ships like tankers, which are major contributors to the shipping industry's carbon footprint. While zero-emissions technologies may still be years away for these vessels, the adoption of lower-sulphur fuels is a step towards reducing their environmental impact.

Hydrogen fuel cells are a zero-emissions alternative
Tanker ships, along with the rest of the shipping industry, are major contributors to the world's carbon footprint. They burn fossil fuels, which significantly contribute to the warming of the atmosphere and the shifting of climate patterns.
However, there is a growing consensus within the industry that a transition away from fossil fuels is necessary. Hydrogen fuel cells are considered a viable zero-emissions alternative for larger, long-distance ships. Hydrogen fuel cells chemically convert hydrogen into electricity without burning it, and the only emission is water. Hydrogen fuel cells can produce power for most trips' durations, whereas batteries would need to stop and charge, which is impossible in the middle of the ocean. Hydrogenics, a company that has installed its fuel cells in various vehicles, including trains, cars, and a research vessel in Turkey, views the marine space as a natural adopter of fuel cells.
Sandia National Laboratories is conducting extensive research on the feasibility, optimization, and safety of hydrogen fuel cells in maritime environments, with an emphasis on powering both docked vessels and operational ships. They have deployed the first containerized fuel cell system, the MarFC, used for powering refrigerated containers at Honolulu Harbor and providing onshore power for a research vessel.
A Global Maritime Forum study from March 2021 examined 106 projects looking at zero emissions in maritime shipping worldwide and found that nearly half of these initiatives focused on hydrogen as a low-carbon fuel source. Oil major Royal Dutch Shell has also invested in several hydrogen production projects, arguing that hydrogen is advantageous over other potential zero-emissions fuels for shipping. The ease of retrofitting existing ships with hydrogen fuel cells is a significant advantage, and hydrogen fuel could replace 43% of voyages between the US and China without any changes and 99% with minor changes to fuel capacity or operations.
While hydrogen fuel cells show promise, there are challenges to their implementation, including the high expense of installing enough fuel cells to power a ship. Additionally, nearly all hydrogen is currently produced using fossil fuels, which limits its sustainability. However, with growing private and public interest in decarbonization, hydrogen fuel cells are expected to play a crucial role in the shipping industry's transition to cleaner energy sources.

Liquefied natural gas is a cleaner-burning fuel
The shipping industry is responsible for moving about 90% of globally traded goods, including fuel, medicine, food, electronics, and raw materials. However, it also contributes significantly to the warming atmosphere and shifting climate patterns.
In 2017, a Wired article reported that container ships use super-dirty fuel, which needs to change. The article also mentioned a red tanker hauling liquefied natural gas (LNG) produced in the United States to terminals in Mexico. LNG is considered a cleaner-burning fuel.
Liquefied natural gas is indeed a cleaner-burning fuel compared to the heavy fuel oil (HFO) or bunker fuel commonly used in larger ocean-going vessels. LNG produces fewer emissions and contains lower sulphur content, making it a more environmentally friendly option. LNG has gained recognition as a viable alternative fuel for ships, as it can significantly reduce harmful emissions, such as sulphur oxide and nitrogen oxide.
The use of LNG as a marine fuel offers several advantages. Firstly, it is a more stable fuel source, as LNG prices are less volatile compared to traditional marine fuels. This stability can help ship operators better manage their fuel costs and budget more effectively. Additionally, LNG-fuelled vessels often experience improved engine performance and increased fuel efficiency. The combustion of LNG results in lower carbon emissions and reduced particulate matter, benefiting both the environment and human health.
While LNG is a step in the right direction, it is not a perfect solution. The infrastructure for LNG bunkering is still developing, and the availability of LNG refuelling stations at ports remains a challenge. Additionally, LNG has a larger space requirement than traditional marine fuels, which can impact the design and cargo capacity of ships. Nevertheless, the adoption of LNG as a marine fuel is a positive step towards reducing the environmental impact of the shipping industry.

Bunker fuel contains up to 2000 times more sulphur than diesel
The shipping industry is responsible for moving about 90% of all globally traded goods, including fuel, medicine, food, electronics, and even livestock. However, it is also a major contributor to the world's carbon footprint. The fossil fuels burned by container ships, tankers, and bulk carriers are causing significant harm to the environment and contributing to climate change.
One of the main issues is the use of bunker fuel, which is a type of heavy fuel oil (HFO) with a very high sulphur content. Bunker fuel contains up to 2000 times more sulphur than the diesel used in automobiles. This has been linked to asthma, cancer, and other respiratory diseases. It is also a component of acid rain, which damages vegetation and wildlife.
The International Maritime Organization (IMO) has recognized the need to reduce emissions from shipping and has implemented regulations to that effect. In 2020, the IMO introduced a global sulphur cap of 0.50% on marine fuel emissions. This means that ships must either switch to low-sulphur fuels or install filters or "scrubbers" to reduce sulphur emissions.
Some shipping companies are also investing in renewable fuels and cleaner technologies, such as hydrogen fuel cells, batteries, and liquefied natural gas. However, there is still widespread reluctance within the industry to adopt meaningful change. The high cost of cleaner fuels and technologies is often cited as a barrier to their implementation.
As a result of these challenges, the shipping industry's transition to cleaner energy may still be years away. However, early projects with ferries and cruise ships could help convince shipbuilders and operators that alternative fuels and technologies are viable and necessary to protect the planet.
