ENERGY EFFICIENCY – Cost of Shore Power Nine Times Costlier than Fuel Switching!
Researchers are of the opinion that the use of shore-side power for reducing emissions from vessels at berth is “less appealing” than other emissions reduction methods.
The study, ‘Costs and benefits of shore power at the port of Shenzhen’, found costs to reduce one tonne of particulate matter (PM) through onshore power equivalent to nine times the cost of fuel switching.
It was calculated on the basis that market penetration of shore-side power was 50%.
The research recommended that fuel switching should generally take precedence over onshore power because it is cheaper and technologically less challenging, especially in China apart from considering another factor, pollution.
