Electric Propulsion in Cargo Ships: A Growing Trend
The maritime industry is changing fast, with electric propulsion in cargo ships becoming more popular. This change is driven by the need to cut emissions and improve fuel efficiency. Cargo ship operators are now using new propulsion technologies like hybrid electric systems and battery-powered vessels.
Recently, over 1GWh of batteries started working in cargo ships around the world. This shows a 72% increase in electric propulsion in 2022. Electric ferries made up 37% of all battery capacity delivered from 2019 to 2022. Norway leads with about 100 electric ferries, the most in the world.
Switching to electric propulsion helps with environmental concerns and brings big benefits. Hybrid propulsion technology can cut fuel use by almost 20% and reduce CO2 emissions by up to 15%. This makes it a key player in the electric ship market.
Advances in battery technology and energy storage solutions are making electric cargo ships more efficient. IDTechEx predicts more electric cargo ship deals coming up. This is thanks to new rules and bigger battery systems becoming available.
The global electric ship market is set to grow from $4.33 billion in 2024 to $17.20 billion by 2032. This means an 18.8% growth rate over the forecast period. This growth is thanks to the industry’s push for maritime decarbonization strategies and using alternative fuel technologies.

Shore Power and Port Infrastructure: Enabling Electrification
The use of electric propulsion systems in cargo ships needs strong shore power and port facilities. Shore power, or cold ironing, connects ships to land power while docked. This cuts down on air pollution and noise in ports.
Having shore power and renewable energy in ports helps hybrid-electric propulsion for ships and emission-free shipping solutions grow. Hybrid ship engines and electrified fleets need this shore-side setup to recharge and be more eco-friendly.
| Key Insights | Statistics |
|---|---|
| Cavotec has equipped over 1,000 ships with its shore power systems in the past two decades, with nearly 70% being container ships. A single container ship at port may require up to 7.5 MVA of electricity to power its equipment and cargo, such as reefer containers. Shore power projects typically take 3 to 4 years from feasibility studies to vessel connection. Connecting to shore power can reduce fuel consumption and emissions by as much as 10% depending on the vessel type and trade. | Cavotec has supplied electrical socket boxes to more than 40 container terminals worldwide. Wabtec offers various cable management solutions for providing shore power to vessels, such as cable reels, junction boxes, and moveable solutions. By 2030, all container and passenger ships will be required to connect to shore power when in a Trans-European Network port for more than two hours. Wärtsilä has installed shore power solutions on 150 vessels worldwide. |
Shore power has been around for over 20 years but is still growing in the maritime world. It faces challenges like long project times and the need for global standards. Yet, building shore power and using renewable energy in ports is key to making electric ship propulsion systems and alternative fuel propulsion technologies common in cargo shipping.
