The shipping industry is experimenting with foils, sails and fuel to make itself less carbon intensive.
Reporting"Even in big waves and wind, we can see the benefits of flying above the waves," says Katrina Thompson, programme director at Artemis Technologies.
Combine with an electric motor and you have, according to Artemis, a vessel which reduces fuel costs by 90% and is emission-free.Dr Thompson grew up in Sailortown, Belfast, in amongst the bustle of heavy industry. She spent her childhood playing on the docks while her parents worked on the boats. Artemis brings together motorsports experts, aeronautical engineers, specialists in flight controls and physics modelling, as well as naval architects.
Wake caused by maritime traffic causes coastal degradation, shore erosion and loss of habitats. Artemis is allowed to operate close to the harbour, at higher speeds than other vessels, due to the lack of wake, promising significantly reduced journey times too. Moving to hydrogen, however, would require changes to fuelling infrastructure. Storage and cost are significant challenges, as well as the adaptation of the ships themselves to enable them to run on hydrogen.Image caption,Experts at Cambridge University say syngas produced by artificial photosynthesis could bridge the gap between fossil fuels and clean hydrogen.
