Hong Kong-based startup Neptune Robotics says its biofoul cleaning robots can reduce <\/strong>fuel consumption per trip by at least 18%<\/strong>, Bloomberg<\/a> reported last week. A thin layer of algae, seaweed, and barnacles covering half of a vessel can increase emissions by up to 30% by creating resistance in the water, according to a study (pdf)<\/a>. \u201cIt\u2019s like swimming with a thick blanket,\u201d Neptune co-founder Elizabeth Chan said. <\/p>\n

How it works: <\/strong>Using AI, the robots first identify the type of biofouling on a ship\u2019s hull and the thickness of the layer before mapping out a plan for cleaning. The cleaning process is similar to cleaning off tarnish from jewelry and involves vibrating the biofoul off the vessel\u2019s hull using high-velocity microdrops of water. The robots cannot reach spots like the ship\u2019s propellers.<\/p>\n

The benefit is on several fronts: <\/strong>Neptune\u2019s robots have helped the shipping industry avoid about 1 mn tons of emissions since 2020 by cleaning 700 vessels, with the cost of cleaning falling between USD 12k and USD 40k. The use of robots can also increase safety, since it eliminates the need for divers to clean hulls. Humans are still needed to launch the robots from a boat and to review the cleaning process.<\/p>\n

The shipping industry has been in hot water: <\/strong>A majority of countries at the International Maritime Organization\u2019s (IMO) two-week negotiations on climate policy were in favor of mandating a global emissions levy<\/a> starting next year. The levy \u2014 which was backed by 34 countries \u2014 will help countries achieve the revised emissions targets approved last year which some experts are already doubting its feasibility. Revenues collected from the tax could be put towards developing low emissions shipping fuels and fund the energy transition of poorer states. Delegates at the IMO are expected to hold talks in the fall to further discuss the different proposals for a carbon levy.<\/p>\n","protected":false},"excerpt":{"rendered":"
