Ports of Auckland has welcomed Sparky, the world’s first full-sized electric tug boat, to Tāmaki Makaurau, reports Newshub. The arrival has been heralded as a significant milestone for tugs, which traditionally are fuelled by diesel. According to website EVs and Beyond, the e-tug is as powerful as the port’s strongest diesel tug – called Hauraki. Sparky is anticipated to save around 465 tonnes of CO2 in diesel emissions annually, with an annual running cost of less than a third than that of traditional tugs.
