Hong Kong professor’s biofilm breakthrough could save shipping companies billions and protect marine life
He is honoured for the creation of a coating that repels barnacles, which is also good for the environment
In a Kowloon lab looking out to the ocean, a Hong Kong professor made a discovery that he believes could save navies and shipping companies around the world billions of dollars every year, as well as protect marine ecosystems.
Hong Kong University of Science and Technology professor Qian Peiyuan was awarded the second-class honour of the State Council’s National Science Award last month for his breakthrough research into how climate change impacts the marine ecosystem and affects what life forms can grow.
Now, Qian’s findings have been used to create a product, the first of its kind patented in China, which will protect ship hulls and other objects immersed in the ocean from barnacles. It’s a problem that costs navies and shipping companies up to 40 per cent extra in fuel costs - or US$15 billion a year, he said at a press conference on Tuesday.
Navies currently use copper or toxic “anti-fouling” solutions to stop the “serious economic cost” of barnacles on their ships, meaning they save on fuel consumption, but harm marine life.
Over about eight years of research, Qian found that biofilm - micro-organisms that can cover any surface, including hair and teeth - are affected by climate change in the ocean.
