An anonymous reader quotes a report from Bloomberg: Four Japanese companies have teamed up to build the world’s first zero-emission tanker by mid-2021 that will be powered by large-capacity batteries and will operate in Tokyo Bay, according to a statement on Tuesday. The new company e5 Lab is a venture between Asahi Tanker, Exeno Yamamizu, Mitsui O.S.K. Lines and Mitsubishi. The global maritime industry is facing an onslaught of legislation to improve its environmental performance. From next year, a majority of vessels will have to burn fuel containing less sulfur. A challenge requiring even more innovation, though, is a goal to halve shipping’s carbon emissions by 2050.
While fully-electric ships have struggled to penetrate major markets, momentum is gathering. Rolls-Royce said last year that it had started offering battery-powered ship engines, while Norway’s Kongsberg Gruppen ASA is developing an electric container vessel. Still, there are challenges in making the technology applicable to ships navigating thousands of miles across oceans because of the need to recharge batteries. Industries from auto to aviation are also looking to go electric. Komatsu, the world’s second-biggest construction equipment, has developed its first-battery powered electric diggers. Electric-plane company Eviation Aircraft, which has signed up its first customer, predicts that in a few years it may not be able to keep up with orders.
