Electric Ships Garner Demand To Reduce Carbon Footprint Globally

Electric Ships Enter The Game

The international shipping industry's carbon footprint has gained widespread attention in recent years. The industry has been working on several alternatives to fossil fuels, including electric ships powered by lithium-ion batteries, which are typically the largest individual batteries in the whole electric vehicle industry. Market players, vendors, end users, and other parties have been steadily adding to the sector's market value.

For instance, the market for electric ships was valued at 5.50 billion dollars in 2021 and is expected to reach 10.82 billion dollars by 2028. Additionally, since electric hybrid systems combine power from energy storage and generators to give the vessel operator a dual power source for better operating flexibility, they produce significantly less pollution than a conventional mechanical propulsion engine.

Electric Ships

How do cruise ship generate electricity

All-electric ships have efficient, clean electric propulsion and power systems that don't emit any noise or carbon emissions into the atmosphere. Additionally, these systems don't leave hazardous residues or fuel spills in our lakes, rivers, or streams. Additionally, operators may decide to have more independence by owning their power source because electricity for shore power charging can be produced in a variety of methods, including solar panels and other renewable sources.

Although electrical systems have been incorporated into the designs of boats and ships for more than a century, most of these systems have primarily been intended to power lighting and accessories. They have therefore frequently been viewed as technology that was added as an afterthought to outdated ICE marine systems.

However, the most cutting-edge electric ships of today are constructed around next-generation electric drive systems, which combine stronger modular power electronics with drive materials especially made to maximize the efficiency of electric motors in maritime conditions. With a more effective utilization of power and a greater operational range, this has improved performance on the water.

With the help of revolutionary new battery technologies, sensor-optimized smart motors, and the urgent need to reduce greenhouse gas emissions, recent improvements in electric boat propulsion systems have significantly increased the demand for clean, zero-emission maritime power options. This demand can only be met by more advanced battery electric and hydrogen fuel cell electric systems.

There is a demand for electric boat power and propulsion systems in every nation with a shoreline or significant inland waterway system, and rising climate change-related events are only escalating that demand. However, the majority of electric boat power and propulsion system developers are in the United States and Europe.

Major Electric Ship Projects

Stena Jutlandica

An agreement pledging the required financial resources for the launch of two battery-powered Stena Elektra vessels by 2030 was signed by Stena Line, Frederikshavn Municipality, and the Port of Frederikshavn.

The two RoPax ferries will each have a capacity for around 3,000 lane meters of vehicles and will be about 200 meters long. These ferries, which can hold 1,000 to 1,500 passengers, are said to be the first RoPax vessels of their size that are completely free of fossil fuels. They will need a high voltage shore power cable of about 30–40 MW and batteries with a capacity of 60–70 MWh.


The largest battery system ever deployed to a ship is a 10,000kWh lithium-ion battery system that Corvus Energy, a developer of energy storage solutions, provided to the German cruise line AIDA Cruises. On the company's AIDAperla cruise ship, which has a capacity of over 4,000 guests and cruise members, the battery was installed in 2019.


Denmark is running the largest all-electric boat in the world, which it expects will reduce CO2 emissions by 2,000 tonnes annually. Additionally, the E-ferry Ellen, as she has been dubbed, is equipped with the biggest battery ever put into a seagoing electric vehicle. It presently travels four times daily the 22 km distance between Søby, on the Danish island of Ærø, and Fynshav, on the island of Als. This will eventually be increased to five to seven times per day.

She can travel up to 22 nautical miles (almost 38 km) with 147 passengers and about 30 cars in the winter and 198 passengers during the summer on a single charge. Even the most advanced electric ferries could not travel this distance seven times. The ship has a length of slightly under 60 meters, a breadth of 13 meters, and a top speed of 15.5 knots, or 17.8 mph or 29 km/h. Two 750 kW electric motors and two 250 kW thrusters are part of this Danfoss system. They also developed and constructed the charging system required to refuel the ship in port.
