China has launched the first all-electric cargo ship. According to China Daily, the 230 foot long vessel is equipped with a 2,400 kWh lithium-ion battery that stores enough electrical energy to transport 2200 tons of cargo a distance of 50 miles on a single charge at a top speed of about 8 miles per hour.
Time to recharge the battery is given as 2 hours, which is approximately the time needed to unload the ship at its destination.
“As the ship is fully
electric powered, it poses no threats to the environment. The technology will
soon be likely … used in passenger or engineering ships,” said Huang Jialin,
chairman and general manager of Hangzhou Modern Ship Design & Research Co,
which designed the electric cargo vessel. The battery for the ship is comprised
of 1,000 individual lithium-ion packs. Adding enough power to carry more cargo
is simply a matter of adding more battery packs.
CSSC stands for China State
Shipbuilding Corporation. The new ship has two primary benefits. First, it will
emit no carbon emissions while underway. Cargo vessels tend to be some of the
biggest carbon pollution sources in the entire transportation sector. Second,
it will lower the cost of transportation for bulk cargoes because the price of
electricity is lower than the price of diesel fuel
Here’s the bad news: The
all-electric cargo ship will be used primarily to transport coal to generating
stations along the Pearl River.
So, imagine this — the world
now has a ship that can claim to be zero emissions even though it is powered by
electricity generated by burning coal, one of the dirtiest of fossil fuels in
terms of carbon emissions, and is used to transport coal more cheaply.
“This kind of ship takes
into consideration the harmony between humans and nature and can protect water
quality and marine life, and should be copied by other ships sailing on local
rivers,” says Chinese environmentalist Wang Yongchen. That much is correct. The
same technology that makes the new electric collier possible can also be used
to power ferries, container ships, or other vessels used for short haul coastal
shipping.
The Chinese should be
applauded for advancing the idea of electric propulsion for ships, but using
clean power to lower the cost of shipping coal to electric generating plants
illustrates how far the world has to go before a zero-emissions world becomes a
realistic possibility.
