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.
Which solution would be optimal for your vessels? The following are examples of actual solutions.

Technology group Wärtsilä will supply the main power generation and power conversion system for a new 103.16m Antarctic Support Vessel being built for the Brazilian Navy. The order has been placed by Brazil’s Estaleiro Jurong Aracruz shipyard and will be booked with Wärtsilä in Q3 2023.
The new Polar Vessel – Navio Polar Almirante Saldanha (NPo) – will be operated by the Brazilian Navy and is of strategic importance for maintaining the Brazilian presence in the Antarctic continent and ensuring the continuity of the scientific research that has been carried out at the Comandante Ferraz Antarctic Station.
The full Wärtsilä scope for the vessel includes three Wärtsilä 32 diesel generating sets, a diesel-electric power conversion system and two bow thruster drive systems, as well as the Power Management System. Wärtsilä’s low emission energy efficient solution ensures optimum performance, combined with high redundancy and availability, thanks to long times between overhauls and low fuel consumption. thanks to long times between overhauls and low fuel consumption.
“With the company’s long-standing and extensive experience in marine technology, we trust Wärtsilä to deliver high quality and reliability in all their products and systems. These specialised vessels require superior performance, and we are confident that the Wärtsilä solutions selected will meet this requirement,” says Maicon Batista Pinto - Project Manager –Navio Polar, NPo.
“We are very proud that Jurong has put their trust in Wärtsilä to be the supplier of this extensive solution for the Antarctic Support Vessel. Thanks to Wärtsilä’s advanced technologies, the overall Wärtsilä solution has been optimised to provide the best possible efficiency for the Brazilian Navy’s operations. This efficiency will also minimise emissions, which is in line with our core strategy of enhancing sustainability wherever possible,” says Simon Riddle General Manager Naval Sales, Wärtsilä.
The Wärtsilä equipment is scheduled for delivery to the yard commencing in 2024 and the vessel is expected to be commissioned in 2025.
