Conserving Energy & Reducing Carbon
YICT, through its eco-friendly technologies, is able to reduce the carbon footprint of its terminal operations and thus cut costs substantially. For YICT, it is a win-win deal, realising enterprise profits while practising corporate social responsibility.
eRTGCs
To reduce port emissions and save fuel, YICT began a project in 2007 to reconfigure its diesel cranes to run on electric power. YICT now has 114 electric rubber-tyred gantry cranes (eRTGC) in operation.
1. eRTGCs emit up to 95% less exhaust, use up to 80% less fuel and produce about 45% less noise than conventional RTGCs.

2. A collector trolley, including cable and plug, which is to be connected to the RTGC

3. The conductor bar system used in RTGC electrification

Hybrid RTGCs
YICT¡¯s hybrid RTGC project aims to save energy and reduce emissions by converting conventional cranes into hybrid cranes that run on a combination of stored power and diesel. Three different hybrid technologies have proved feasible: a diesel plus flywheel energy storage solution, a diesel plus lithium-ion battery solution, and a diesel plus nickel-metal hydride battery solution. These technologies can reduce fuel use by 40% and polluting emissions by 50%.
The hybrid power device

Use of Solar Energy
1. The solar panels installed in the port area provide energy for water heating, helping to save 12,000 kWh of electricity a year

2. The solar power light poles use 40,000 kWh less of electricity a year compared with conventional light poles.

Quay Crane Lighting
Newly delivered quay cranes are now equipped with the latest LED technology. The 10W crane lamps consume less than one-fourth of the electricity of fluorescent lamps and can last for up to 50,000 hours ¨C about 17 times longer than conventional fluorescent lamps.

Container Yard Illumination
YICT adjusted its container yard lighting after noting the comparatively low truck traffic at night. Half of the yard lights now turn off automatically after midnight. This has helped to save electricity by 20%, which amounts to 840,000 kWh per year.
