。 The two ferries made their debut in New York on October 6, fueled by locally produced hydropower. When passengers climb on and off the ship, their batteries can be recharged in as little as seven minutes. < / P > < p > the new ship, operated by the mail of the mist, is one of the first of its kind to sail by water in the United States. The first all electric passenger and car ferry in the United States will be launched from the Alabama River in 2019. These new, pollution-free voyages are part of a global trend towards passenger ship electrification. < / P > < p > “the electrification of these two new cruise ships sets an example that we can electrify the economy, which is good for our community, health and climate.” Gil quiniones, President and chief executive officer of the New York electric power authority, said in a statement. The New York electricity authority and New York State Park worked with the maid of the mist company to float the ships, while abb, an automation company, installed battery packs for the ships. < / P > < p > the carbon footprint of the marine industry is similar to that of the aviation industry, and efforts are being made to control the earth’s heat emissions from the traditional diesel powered fleet. However, ferries account for only a small proportion of carbon dioxide pollution in the transport industry. They pumped out about 11.6 million tons of greenhouse gases in 2018, about the amount of emissions that three coal-fired power plants could produce in a year, and even less than a third of the annual carbon footprint of a large airline like delta (before the pandemic). < / P > < p > but diesel powered boats can be harmful to local air quality, as they also release smoke and nitrogen oxides, which exacerbate smog. As ferries travel the same route every day, pollution accumulates in nearby communities. < / P > < p > these frequent and relatively short trips make ferries an ideal choice to replace diesel engines with rechargeable batteries. The Nordic countries with a long maritime tradition have led this trend. In 2015, the world’s first electric vehicle and passenger ferry service began in Norway. Finland transformed its oldest operational ferry into an all electric one in 2017. Since then, electric passenger ships have appeared in Denmark, Spain, India and Thailand. Anil Srivastava, chief executive of Leclanche SA, a Swiss battery maker, said in January that more than 70% of the world’s ferry traffic could become fully electric. Papatrick Finn, a marine technology analyst at the consulting firm thetius, said: & quot; we have a while to see the electric boat revolution in the United States, but it’s happening elsewhere in the world;. According to Finn, the United States is catching up because building ships in the United States is more expensive than anywhere in the world. Why is the price so high? He pointed out that the controversial Jones Act is a 100 year old law that requires ships carrying goods between two ports in the United States to be made in the United States. This requires significant policy changes and investment to drive a faster shift to electric boats. < / P > < p > in addition, significant infrastructure updates are needed to fully electrify the ferry fleet. Aging power grids designed for fossil fuels need to be retrofitted to accommodate more renewable energy sources. It also requires charging stations and enough power to be ready at busy ports. Niagara Falls cruise ships are lucky to cruise through a powerful source of clean energy – the waterfall generates enough electricity for 3.8 million homes on each trip. &It’s basically the perfect application of (all electric boats), & quot; says John nuszkowski, an associate professor of mechanical engineering at the University of North Florida, who grew up not far from Niagara Falls. Battery technology has not developed enough to replace diesel engines for cargo ships and large ocean going ships. In terms of reducing marine pollution, hybrid ships or ships using alternative fuels are still promising. There is a long way to go before electric boats “take over” the ocean.
