Ever since his mechanically-minded grandfather renovated a bicycle, then a motorbike, then a boat back in the 1920s, Mr Kooij’s family has been at the heart of Amsterdam’s tourist canal boat business.
Now the Reederij Kooij boat company he runs with his wife Daniela is one of the largest plying Amsterdam’s famous canals. It owns 32 boats out of about 150 catering to the city’s many tourists.
He has converted six boats so far – it takes about three months to strip out the old diesel engine and install the electric engine and batteries. A typical 23m (75ft) tourist boat needs about 66 batteries, he says, making the conversion cost around 165,000 to 250,000 euros ($189,000 to $287,000; £145,000 to £220,000) per boat.
But the engines are quieter, cleaner and cheaper to run – boat companies should recoup their costs in about 12 years, according to the Paris Process on Mobility and Climate, a body supporting sustainable transport projects.
They can be recharged in about 10 hours and last about two days between charges, says Sigrid Hanekamp, an application engineer from Dutch battery company Lithium Werks, which supplied the batteries for Reederij Kooij’s boats.
These batteries are not your typical lead-acid type traditionally used in cars, or even the type of lithium-ion ones becoming standard in electric vehicles, she explains. They’re lithium-iron-phosphate, a chemistry Lithium Werks believes is more durable and environmentally friendly.
