Clearing The Air In Ports

摘要

The air in ports is no longer thick with smoke and dust, but there is still pressure to make it even cleaner. John Guy looks at the Hydrogen Hybrid Harbour Tug (HHHT) project aimed at tackling the issue. One method of improving air quality in ports is to force ships to 'cold iron' while alongside. However, that still leaves the issue of emissions while berthing. One way to limit that is to use tugs more for the berthing, limiting ship main engine use, and focus on the emissions from the tugs and other support craft in the port.
