Interview: reducing ship emissions with power from shore

Ships still consume energy when they are berthed at port, running their diesel generators to power onboard facilities and emitting CO2, nitrogen oxides and sulfur oxides in the process. With growing pressure on the industry to reduce emissions, an increasing number of ports are introducing shore-to-ship power supplies to enable the ships to draw electricity right from the quayside. ABB's Knut Marquart presented a paper at the World Energy Congress on Sept. 15 on "Effectively reducing emissions from ports," and explains in this interview how it works.
