Asia's First Hybrid Electric Ferry Heralds Cleaner Sea Travel

 

Kaohsiung recently re-launched the Cijian Island passenger ferry, retrofitted with a Visedo electric propulsion system, replacing the original diesel engine. It heralds Asia’s first hybrid electric ferry and, if successful, the Kaohsiung City Government plans to retrofit the rest of its diesel fleet to help reduce pollution levels around Taiwan’s largest harbor.

 

Visedo OY, a Finnish manufacturer of electric drive trains for marine vessels, commercial vehicles and heavy duty applications, worked alongside Taiwan’s Ship and Ocean Industries R&D Center, also known as SOIC, to complete the retrofit.

 

Visedo CEO Kimmo Rauma said, “Given the geography, ferries are a vital mode of public transport across East and Southeast Asia but they are also the most energy intensive per kilometer travelled. Until now, diesel ferries have been a dirty but necessary part of life around harbors like Kaohsiung.”

 

“In Hong Kong for example, passenger ferries make up the majority of licensed vessels in Victoria Harbor, where it’s estimated air pollution kills about 3,200 people every year,” Rauma continued.

 

“Visedo has developed a cost-effective and efficient alternative, so rather than waiting until a vessel’s service life ends, harbor cities can swap noisy, dirty and expensive diesel for silent electric powertrains that are more efficient, can halve fuel costs and emit no fumes or oil pollution.”

 

Kaohsiung’s new e-ferry, Ferry Happiness, will halve daily fuel consumption while transporting 15,000 passengers every day to Cijian Island, a popular tourist destination in Taiwan, at a top speed of nine knots.

 

Launching from berth every 15 minutes, the ferry will help share the eight million passengers who travel the 650m route every year. It’s estimated the electric propulsion will save more than 25,000lt of fuel every year.

 

Visedo retrofitted the 100-metric-ton, 23m-long vessel with an electric system to replace the original 300HP diesel engine. The power train was designed to ensure pure electric cruising for half the ferry’s operation time and, with fast shore charging, this pure electric percentage can be higher.

 

Head of SOIC’s System Development ChihHung Lin said, “Like many East Asian harbor cities, in Kaoshiung ferries play a key role for everyday public transport, often playing the role that buses do elsewhere.”

 

“Taiwan’s ‘Harbor Capital’ has long suffered from air pollution and only a few years ago the average person was consuming double the national Taiwan average of carbon dioxide.”

 

“In response the Kaoshiung City Government is committed to cleaning up its fleet and is currently considering the possibility of replacing all 11 of its vessels with this new type of e-ferry. This also includes embarking on a hybrid tug-boat project.”
