Electric shipping and hybrid ships are important solutions now that the marine industry has entered a new era – the age of decarbonisation and strict regulation. Vessels must be future proof: flexible enough to adapt to the changing needs in the future. As the regulation evolves and restrictions on emissions become stricter, the best way to stay competitive is to rely on the best available technologies. Electric shipping or ship electrification is one of the key solutions for marine decarbonisation.
The future of shipping is here: Discover how these interesting electrical solutions can reduce the environmental footprint for different vessels.
Electrical solutions will deliver reduced emissions as retrofits and offer a competitive advantage also for newbuild vessels.
Electrical solutions have been part of vessel design for many years in the form of diesel-electric propulsion or shaft generators, for example. The share of green energy – from renewable sources such as wind, water, and solar – in land-based electrical grids is on the increase.
It makes sense for ships to take advantage of shore-based green energy. As an example, using a shore connection can reduce emissions significantly while the ship is in port. Depending on the vessel and its operating profile there are many ways to reduce its emission footprint. The key is optimisation: finding the right solution for each vessel.
Slow steaming used to be the favourite solution for many vessels to reduce emissions. Flexibility was not an issue then, so this means that some vessels will never be fully optimised. Electrical systems onboard make it possible to use smarter propulsion systems. Smarter, more resilient, and more flexible – and thus capable of adapting to the changing needs in the future of shipping.
Deepsea vessels will have to adopt green fuel engine technology to decarbonise. Electrical systems will be an integral part of the system including shaft generators and shore connection. Electric cruise ships and electric cargo ships are a futuristic concept, but they can go hybrid and take advantage of solar energy to improve their efficiency.
Tugs can benefit from hybrid or even full electric solutions. They operate close to the shore to land based electrical infrastructure. Because they have high load variations and spend long periods of time on standby, hybrid electric solutions will cut their GHG emissions significantly.
Ferries are often part of local transportation routes and can easily use the land-based charging infrastructure. If the route is short enough, the ferry can even be fully electric. Many ferries still prefer to have a hybrid electric solution to minimise risks.
Any short-distance or coastal vessel can be a hybrid ship. They can charge their ship battery with green energy available at the port. They can be a zero emission ship while manoeuvring, station keeping, and port navigating if they switch to full electric power during those operations.

The technology group Wärtsilä and logistics provider CLdN have jointly developed an innovative hybrid design for two new RoRo vessels. The propulsion arrangement is such that the ships can operate as gas/diesel-mechanical vessel now, or in the future as gas/diesel-electric vessel. The vessels are being built at Hyundai Mipo Dockyards in Korea.
The Wärtsilä hybrid system includes Energy Storage Systems, two large PTO/PTI generators and electric motors, multidrive converters, and the Wärtsilä Energy Management System that controls and optimises the hybrid operations. The solution will enable the ships’ CO2 emissions to be minimised, thereby supporting the marine sector’s decarbonisation ambitions. The order with Wärtsilä was placed in June 2022.
“Our aim is to be flexible with regard to future technological developments, which is why we have worked on the development of these new vessels with Wärtsilä, a company with a proven track record in developing advanced hybrid technology for the marine industry,” says Gary Walker, COO Shipping at CLdN.
“Decarbonisation is a central issue for shipping today, which means that vessel designs need drastic re-thinking. It’s not always clear, however, what these changes should involve, so we at Wärtsilä have for some time now been recommending that built-in flexibility in the propulsion train should be a priority. Together with CLdN, with these vessels we are showcasing what is today both possible and meaningful,” says Torsten Bûssow, Director Ship Electrification Solutions at Wärtsilä.
The two 234 metre long vessels will each feature 8000 lane metres of cargo space. They are part of CLdN’s fleet renewal programme aimed at drastically reducing emissions. The ships are scheduled to be delivered in Q4 2024 and Q1 2025, and will operate on CLdN’s European network.
Wärtsilä is a market leader in hybrid solutions for shipping applications with installations onboard more than 70 vessels and in excess of 100 MWh installed battery capacity. The company has a long-standing and well-established relationship with CLdN.
