Nuclear energy

Nuclear propulsion has the potential to become one of the main alternatives to achieve sustainable marine shipping and reduce GHG emissions. While it has a high capital expenditure compared to conventional marine propulsion, if applied, C-Job predicts that it could be cost-effective to shipowners within five to fifteen years.

Through our research, we have found that large, ocean-going vessels are likely to be the best candidates for nuclear propulsion, and they will benefit from a 100% reduction of tank-to-propeller GHG emissions.

While nuclear technology has not been widely considered as a viable option to date, it has also seen interesting developments recently, such as high temperature gas reactors (HTGRs) and molten salt reactors (MSRs). These help to demonstrate that nuclear technology has serious maritime potential, which will increase as reactor technology and regulations are further developed. C-Job continues to research nuclear energy and its design implications for the maritime industry.

Nuclear study for a bulk carrier

Over the past 10+ years, developments in the next generation of civil nuclear reactors have enabled a reevaluation of nuclear power and nuclear-powered ships. Working with ULC-Energy BV, C-Job helped the client to gain insights into the technical and economic consequences of adopting nuclear power on a bulk carrier – including the potential to reduce harmful emissions for the client’s shipping operations.

Nuclear power could pave the way for bulkers to sail longer, faster, and cheaper, study finds

Compared to a Newcastlemax bulk carrier powered by conventional very low sulfur fuel oil (VLSFO) and one powered by green ammonia, a nuclear-powered Newcastlemax bulk carrier could sail longer, faster, and cheaper, without producing greenhouse gas (GHG) emissions, a new study found.

Nuclear-powered commercial vessel

Research by C-Job demonstrates the potential for nuclear energy to become an alternative energy source which could contribute to the decarbonization of commercial shipping. This is in part due to the development of small modular reactors (SMRs) and advances in nuclear technologies. Additional C-Job studies explore new economical design speeds when using nuclear energy as a propulsion source for future cases.
