Activity 1: Mapping of Port Container Terminals Energy Profile
The main objective of Activity 1 is to describe energy efficiency and greenhouse gas (GHG) emissions profiles into the general models which describe port container terminals (PCTs) processes. Specific methodologies for the carbon footprint evaluation and equipment energy performance will be developed as a previous step for the evaluation of eco-efficient alternatives.
Activity 1 will be focused on the evaluation of energy consumption and GHG emissions calculation of PCTs. The current methodological approach regarding emission estimation methods for port-related activities divide the emissions sources into two categories: mobile sources and stationary sources. Stationary sources involve power plants, buildings, offices and other facilities. The project will be mainly focused on mobile sources as they are the key energy consumers and GHG sources regarding normal conditions in PCTs activities (not expansion works or infrastructure developments).
Mobile sources are commonly powered by fuel-burning engines, although in the last years the provision of hybrid or full electric power units has been developed for newly designed and built PCTs. Unfortunately, for existing PCTs, no conversion of yard equipment to hybrid, LNG-powered or electric equipment has been tested yet. The most common fuel for port mobile sources is diesel fuel and in less percentage, petrol. The predominant greenhouse gas from fuel burning mobile sources is CO2, directly linked with the amount of fuel burned. In this manner, fuel consumption is the key information needed to calculate emissions from these sources. Electric mobile sources produce indirect GHG emissions when the source of electrical power generation is fossil fuel powered. Therefore, it must be pointed out that electrification of equipment activities is not necessarily a zero carbon solution.
The specific milestone scheduled for Activity 1 is the following:
• Report on Port Container Terminals Energy Profile. This report will cover the methodologies, energy consumption maps and profiles, general and specific results, opportunities and constraints identified during the Activity execution.
