Shipping companies have been working on innovative solutions to shipping’s carbon footprint.
Operating cargo ships at lower speed can dramatically reduce emissions, and there have been trials of interesting add-ons like kite-powered ships—although.
Now a major shipping company is installing “spinning” or rotor sails on one of its ocean-going freigt ships, with the hope of testing this technology for fuel savings. The “sails”—made by Finnish company Norsepower—are actually 30-metre columns which are rotated using electricity.
