The industry maritime transport, one of the pillars of global trade, is about to undergo a revolution Energy efficiency. The giant Maersk, in partnership with Lloyd's Register and Core Power, is studying the feasibility of using fourth-generation nuclear reactors to power container ships with nuclear energy.
This innovation consultancy, which promises to operate ships for up to seven years without refueling, could transform the way the world transports goods and faces the environmental challenges of the future.
Nuclear Energy: Carbon Emissions Challenges in the Shipping Sector
Shipping is responsible for around 90% of global trade, but it is also a significant contributor to carbon dioxide emissions, with approximately 3% of global emissions coming from this sector.

At a time when pressure for cleaner fuels and reduced environmental impact is increasing, nuclear power is emerging as a potential solution to decarbonize shipping.
The use of nuclear energy in shipping was considered a risky option due to concerns about financial security, waste management and regulatory acceptance.
However, technological advances in fourth-generation reactors promise to overcome many of these obstacles, offering a safer and more efficient alternative to traditional nuclear technologies.
The operation of fourth generation reactors
Fourth-generation nuclear reactors are designed to be significantly more efficient and safer than current nuclear power plants. They use uranium-238, a more abundant resource, as fuel, which increases efficiency and reduces nuclear waste.
Furthermore, these reactors are designed to prevent serious accidents from occurring, even in extreme situations such as earthquakes, minimizing the risk of releasing radioactive material.
One of the key differentiators of fourth-generation reactors is their ability to operate for long periods without the need for refueling. In the case of container ships, this means that a reactor could provide enough energy to operate for up to seven years, a significant improvement compared to conventional ships, which require regular refueling.
Another crucial aspect is the fuel cycle of fourth-generation reactors, which avoids the separation of uranium and plutonium, making it difficult to create nuclear weapons and increasing the safety of the system as a whole.
Advantages of nuclear powered ships
Ships powered by fourth-generation nuclear reactors offer several advantages in terms of performance and environmental impact. It is estimated that a large container ship requires a propulsion power of between 60 and 70 MW, with a total thermal power of 100 to 150 MW.
This energy would allow the ship to operate for long periods without refueling and reach average speeds higher than those of conventional ships, in the range of 25 to 30 knots.
Most importantly, nuclear-powered ships have the potential to dramatically reduce carbon emissions from the maritime sector. A single nuclear-powered container ship could avoid several hundred thousand tonnes of CO2 emissions per year, making a significant contribution to global emissions reduction targets.
Decarbonization of maritime transport
Decarbonizing shipping is one of the biggest challenges facing the global industry. Fourth-generation nuclear power offers a promising alternative to reduce carbon emissions in this sector, enabling ships to operate for long periods without the need for fossil fuels.
However, the widespread implementation of this technology depends on the creation of rigorous safety standards and global regulatory acceptance. The initiative by Maersk, Lloyd’s Register and Core Power to study the feasibility of nuclear-powered ships is a crucial step in this direction. The success of this project could unlock the potential of nuclear power in shipping, enabling the industry to achieve its net-zero emissions targets.
The use of fourth-generation nuclear reactors in maritime transport represents a paradigm shift in the search for sustainable solutions for the decarbonization of the sector.
With the ability to operate for years without refueling and the promise of dramatically reducing carbon emissions, this technology could transform the way the world moves its goods.
As pressure for cleaner alternatives grows, nuclear power emerges as a viable solution to meet future environmental challenges and ensure more sustainable global trade.
