As the maritime industry shifts towards sustainability, electric motors and renewable energy are transforming the future of shipping. The Mondorf ferry’s successful transition to electricity marks a significant step towards reducing emissions and promoting eco-friendly transportation.
The Future of Shipping: Electric Motors and Renewable Energy
A New Era for Maritime Transportation
The maritime industry is under pressure to reduce its environmental impact. As a result, many shipping companies are turning to electric motors and renewable energy to power their vessels. One example is the Mondorf ferry, which has been making the crossing on electricity since February.
An electric motor is a device that converts electrical energy into mechanical energy.
It consists of a stator and a rotor, with the stator being the stationary part and the rotor being the moving part.
The motor works by using electromagnetic forces to rotate the rotor, which then drives a load such as a wheel or a machine.
Electric motors are widely used in various applications including household appliances, industrial machinery, and transportation systems.
Electric Ferries: A Step Towards Sustainability
The Mondorf ferry’s conversion to an electric motor was made possible by federal funds, which covered up to 80% of the cost. The ship now requires a 1,000 kilowatt-hour battery, equivalent to about 14 electric car batteries, to power its 14-hour day. At night, the ferry recharges with renewable energy while docked at the pier.
Environmental Benefits

Compared to diesel engines, electric motors require less maintenance and produce fewer emissions. This means that running the ferry on a battery will ‘probably be cheaper in the long run,’ even with Germany‘s high electricity prices. Additionally, electric ships eliminate the risk of spills when refueling and reduce noise pollution.
A Global Shift Towards Electric Shipping
Norway is leading the way in electric shipping, with over 1,000 ships already operating with fully electric or hybrid engines, and at least 460 additional electric ships under construction. The country’s goal is to drastically reduce CO2 emissions from shipping by 2030.
Challenges and Opportunities
While electric motors are useful for shorter distances, longer journeys remain a challenge. Some electric ships have a traditional engine on board, powered by diesel, liquefied natural gas, or biodiesel. However, battery technology will likely remain limited over long distances. Biodegradable methanol fuel is currently being used for environmentally friendly ship propulsion.
A Bright Future Ahead
The maritime industry has the potential to significantly reduce its environmental impact with the adoption of electric motors and renewable energy. Industry experts predict that demand for hybrid and fully electric engines will continue to increase, driven by groundbreaking innovations in battery technology and hybrid propulsion systems.
