Port to test ‘sock on a stack’ system

The Californian Port of Long Beach is testing a ‘sock on a stack’ system which could cut emissions from ships by up to 95 per cent. The Advanced Maritime Emissions Control System (AMECS) uses a crane to place a large bonnet-like device over a ship’s smokestack. The exhaust from the ship’s diesel engines is then captured and scrubbed of harmful air pollutants before being released back into the atmosphere. AMECS could be used to cut pollution at berths that are not outfitted with shore power.
