The global trucking, shipping and aviation sectors are currently heavily reliant on fossil fuels, but there are alternative fuels that could be used to replace them. Sustainable hydrogen fuels (SHF) are one such alternative, and they could potentially decarbonise these sectors by 2050. Electrification is another option for some freight transportation, such as short- and medium-haul trucking, but it is more challenging for ocean shipping and aviation.

What You'll Learn
Sustainable hydrogen fuels (SHF) as an alternative to fossil fuels
Sustainable hydrogen fuels (SHF) are a promising alternative to fossil fuels in the trucking and shipping industries. Fossil fuels, such as diesel, fuel oil, and jet fuel, are currently the mainstay of the freight transportation system. However, the shift towards cleaner and more sustainable energy sources is becoming increasingly important to meet climate goals and reduce emissions.
SHF, such as hydrogen and ammonia, offer possible long-term solutions for freight transport. Hydrogen fuel cells use hydrogen as a fuel to drive an electrochemical process that produces electricity, with water and heat as the only by-products. This makes them a clean, reliable, and efficient source of energy. SHF can be produced from renewable energy sources, water, and optionally carbon dioxide or nitrogen captured from the atmosphere.
While electrification is a viable option for short- and medium-haul trucking, it is more challenging for ocean shipping and aviation. In these cases, SHF can play a critical role. For long-haul trucking, hydrogen is the optimal choice, while ammonia is better suited for short-sea shipping. Hydrocarbon eFuels, which can be used in existing combustion engines, are a good alternative for short-haul aviation.
However, there are challenges to the widespread adoption of SHF. Currently, the majority of hydrogen production relies on fossil fuels, contributing to substantial emissions. Additionally, there are high production costs, limited infrastructure, and an underdeveloped value chain. To overcome these obstacles, coordinated efforts are necessary to enhance storage technologies, lower production costs, and establish supportive policies.

Electrification of freight transportation
Fossil fuels are the mainstay of the current freight transportation system, with diesel fuel used for trucks and locomotives, jet fuel for planes, and fuel oil for shipping. However, electrification is a good option for some freight transportation, such as short- and medium-haul trucking.
For long-haul trucking, hydrogen is the optimal choice, as it can be produced from renewable energy sources, water, and optionally carbon dioxide or nitrogen captured from the atmosphere. This fuel is also known as eHydrogen, where the 'e' stands for renewable, electricity-based fuels. eHydrogen depends on electrochemical conversion in fuel cells or adjustments in combustion engines and fuel tanks.
For short-sea shipping, ammonia (eAmmonia) is the best choice, as it can be used as a drop-in fuel in existing engines. eAmmonia is also produced from renewable sources and can be used in combustion engines with adjustments.
While electrification of freight transportation is a promising solution, improving the efficiency of energy use in freight transport will also be critical in reducing our reliance on fossil fuels.

Decarbonisation of the global trucking, shipping and aviation sectors
The global trucking, shipping and aviation sectors currently rely on energy-dense liquid fossil fuels, such as diesel, jet fuel and fuel oil. However, there are several alternatives that could potentially replace these fossil fuels and help to decarbonise these industries.
One option is electrification, which is a good choice for short- and medium-haul trucking, but is more challenging for ocean shipping and aviation. Another option is to use "drop-in" alternative fuels, which can be used in place of fossil fuels in existing engines. However, the limited supply of truly sustainable drop-in fuels means that these will likely only play a niche role in the long term.
Sustainable hydrogen and ammonia fuels offer possible long-term solutions for freight transport that is difficult to electrify. Hydrogen is a particularly good option for long-haul trucking, while ammonia is a better choice for short-sea shipping. Hydrocarbon eFuels, which can be used in existing combustion engines, is a good option for short-haul aviation.
Modelling the value chains from electricity and fuel production to fuel consumption for these different types of transport allows for a comparison of the changes in competition from sustainable hydrogen fuels (SHF) versus fossil fuel use. This can help to outline the total costs of ownership and indicate the optimal SHF choices for each type of transport.

Energy-dense liquid fossil fuels
Electrification is another option for some freight transportation, such as short- and medium-haul trucking, but it is more challenging for ocean shipping and aviation. "Drop-in" alternative fuels, or those that can be used in place of fossil fuels in existing engines, can also play a transitional role if sustainably produced. However, the limited supply of truly sustainable drop-in fuels means they will likely play a more niche role in the long term.
While shifting to sustainable fuels will be critical in meeting climate goals, improving the efficiency of energy use in freight transport will also be essential. Sustainable hydrogen and ammonia offer possible long-term solutions for freight transport that is difficult to electrify.

Sustainable drop-in fuels
EHydrogen is produced by electrochemical conversion in fuel cells, while eFuel can be used in existing combustion engines. eAmmonia depends on adjustments to combustion engines and fuel tanks. These sustainable drop-in fuels offer possible long-term solutions for freight transport that is difficult to electrify, such as ocean shipping and aviation.
The current freight transportation system relies heavily on energy-dense liquid fossil fuels, such as diesel fuel for trucks and locomotives, and jet fuel or fuel oil for shipping. However, the shift to sustainable drop-in fuels is critical in meeting climate goals. While electrification is a good option for some freight transportation, such as short- and medium-haul trucking, it is more challenging for other parts of the freight system.
A dynamic cost model developed by MIT outlines the optimal sustainable hydrogen fuel choices for different modes of transport. The model suggests that hydrogen is the best choice for long-haul trucking, ammonia for short-sea shipping, and hydrocarbon eFuel for short-haul aviation. This model was applied to Norway, considered an early adopter of sustainable transport, and provides a valuable framework for comparing the costs and competition between sustainable hydrogen fuels and fossil fuels.
