Abstract
Voluntary emission reduction of greenhouse gases is conducive to reducing carbon dioxide (CO2) emissions and fostering a carbon trading market. Voluntary greenhouse gas emission reduction methodologies can be used to determine project baselines, demonstrate additionality, calculate emission reductions, and develop monitoring plans. Marine fossil fuel combustion is an important source of greenhouse gas emissions in port. Through the implementation of marine shore power system, it is possible to replace fuel consumption with electricity and significantly reduce greenhouse gas emissions during berthing. Through the analysis and study on shore power system, the methodology of voluntary greenhouse gas emission reduction for shore power system is formed, which is conducive to promoting the participation in carbon emissions trading and promoting the promotion and use of shore power system.
Highlights
Greenhouse gas emissions in ports mainly come from the production of loading and unloading and the burning of fossil fuels during the berthing period of ships
Mode 1: Demonstrate that project activities can’t be implemented because of one or more obstacles, such as the obstacles faced by the construction of shore power system, the policy and regulation obstacles faced by power supply services, and mandatory laws and regulations
The data can be obtained in the following order: (a) Weighted average emission factors for all generators in the current power grid published by authoritative bodies. (b) If the option (a) is not available, the mixed marginal factor (CM) is calculated by the operation marginal factor (OM) and the construction marginal factor (BM) according to the procedure stipulated in the "Power System Emission Factor Calculating Tool"
Summary
1.1 Definition and scope of application (1)Relevant definition Shore power system: it means that during the period of berthing, the generator on the ship will be stopped and the power supply on land will be used instead. Unit time fuel consumption: Fuel consumption per unit time of power generation by ship auxiliaries during berthing. (2) Explanation of scope of application This methodology is applicable to the calculation of emission reduction caused by the use of shore power instead of fuel during berthing of ships. Unit time power consumption: Electricity consumed per unit time by shore power system during berthing. This methodology is limited to projects with annual emission reductions of less than 60,000 tons of carbon dioxide. The principle of selecting all kinds of parameters is to select the measured data first
