In November, Hong Kong’s harbor will see four solar-powered ferries. On a sunny day, 3/4 of ferries’ energy needs will be met by solar power.
On a “typical sunny day” they will operate mainly using the sun’s energy, and also with liquid petroleum gas…The technology could cut in half carbon-dioxide output on a typical urban ferry route, Solar Sailor said on its Web site…The ferries were purchased by the Hong Kong Jockey Club as part of a 350 million Hong Kong dollar ($45 million) drive to make the city more environmentally conscious. The boats will be used for services between the club’s Kau Sai Chau Public Golf Course and Sai Kung pier, it said in September on its Web site. Solar Sailor’s so-called hybrid marine power, a sea-going equivalent to Toyota Motor Corp.’s Prius car, according to Chief Executive Officer Robert Dane, can save ferry operators $6 million in fuel costs over a typical 15-year lifespan, the company says. Even so, recent development of the technology makes it hard to compete with the more established diesel motor industry, Dane said.
