SOCIAL Cleaner ferry operations improve city air quality, while quieter trips create a more peaceful urban environment.

THE TRIPLE BOTTOM LINE

ENVIRONMENTAL A normal ferry consumes the equivalent of 1,200 MWh per year. Echandia Marine’s propulsion system, by contrast, consumes just 500 MWh, and curbs both air and noise pollution.

In Stockholm, Sweden, Echandia Marine has completed its first commercially demonstrated electrically propelled passenger ferry installation, shuttling citizens throughout the city’s archipelago. The ferry can operate for an hour on just ten minutes of charging. Echandia Marine has developed a cleaner, more environmentally friendly way of powering small- to medium-sized electric commuter ferries. Their innovative propulsion system is virtually silent, consumes very little electricity, and emits no pollutants or greenhouse gases when operating. An Echandia Marine retrofitted ferry consumes just 500 MWh of energy per year, and operates at 90% efficiency, compared to just 28% to 35% for a standard diesel engine, according to the company. Their system uses magnetic electrical motors to power the ferry, which simplifies the propulsion process and cools the motor via surrounding sea water. WHY A SUSTAINIA100 SOLUTION? A conventional ferry consumes about 120 m3 of diesel per year and emits around 300 tons of CO2, according to Echandia. This contributes to climate change, poor air quality, noise pollution, and can cause damage to sensitive foundations such as stones and soil. Echandia Marine helps

ECONOMIC According to Echandia Marine, the system offers a 20% to 30% reduction in operating costs and almost 100% reduction in maintenance costs.

solve these problems by retrofitting existing ferries.

The Movitz vessel, which operates within the city of Stockholm, was retrofitted into an electric ferry during the summer of 2014.
