Cargo ships transport 90% of global trade and are critical to keeping supply chains moving. However shipping is also responsible for 2-3% of the world’s CO2 emissions, but with economies of scale dictating that these ships get bigger and bigger to keep costs down and we’ve got one almighty challenge to find a scalable zero emission solution. Oceanbird, a project between shipping giant Wallenius and manufacturing company Alfa Laval, think that wind power might hold the answer. Imogen went to Stockholm, Sweden to meet the team behind the autonomous wind powered cargo concept and to find out just how difficult it is to make an autonomous wind powered ship and when we can expect to see Oceanbird’s maiden voyage.
