From cargo ships to ferry boats, electrified shipping is beginning to make waves in maritime markets, with the global market estimated to be valued at $16.2 billion by 2030 and big players such as Siemens AG, General Electric and ABB all getting in on the action. While the Yara Birkeland is smaller than some of the cargo ships entering circulation today, which are still fuelled by heavy oil and diesel, the growth in fully electric ships is picking up pace. According to Yara, the Norwegian fertiliser manufacturer behind the new ship, it will replace approximately 40,000 diesel-powered truck journeys a year between their operations throughout Norway – cutting cost, emissions, air pollution and congestion on Norwegian roads. The 80-metre, 3200-tonne ship is the first fully electric autonomous cargo ship in the world, powered by eight batteries with a capacity of 6.8 MWh – the equivalent of 100 Tesla cars – which is drawn almost exclusively from hydropower generation. Quietly, at the tail-end of 2021, the Yara Birkeland set sail from Porsgrunn, a town in the south-east of Norway.
