Xiamen Port electrification reduces emissions

The terminal in Fujian Province began its upgrade and reconstruction project in 2020, acting as a pilot to explore the feasibility of a full-port green transformation.

“When we were building an intelligent port in the beginning, especially using the electric stackers, we kept reliability in mind,” said general manager, Huang Luxu.

“We began renting the electric stackers rather than buying them. After a half-year trial, we thought it was feasible and we started to promote the mode in all the wharfs of Xiamen Port.”

The port says the transformation has greatly reduced operational costs. “The service life for gantry crane engines is 15 years,” continued Huang.

“After using lithium batteries, their power cost is less than half of the cost when using fuel. We estimated that we will reach the break-even point on the engines in six years.”

Crane operators at the port also benefit from the changes as their workplace has shifted from a cabin at an altitude of several metres high to a comfortable control room.

The port estimates that full electrification has reduced diesel consumption by around 2,700 tonnes per year, saving 2,150 tonnes of coal and reducing CO2 emissions by 5,400 tonnes.
