Abstract
Reasonable regional integrated energy planning is an important prerequisite for the construction of a Near-Zero Carbon Emission Demonstration District (NCEDD). An integrated energy planning scheme that is based on a three-step planning method with the objective of achieving an NCEDD is proposed in this paper. First, the planning objectives should be determined. After that, the planning strategies should be established. Finally, the planning approaches should be proposed according to the previously determined objectives and strategies. A case study considering the integrated energy planning of the Meishan International Near-Zero Carbon Emission Demonstration District (MINCEDD) is investigated to explain the planning method. In addition, the planning results, which are indicated as indexes, are explained, analyzed, and compared to the ones of other districts. The indexes include a proportion of renewable energy to primary energy (73% by 2030 and 108% by 2050), a proportion of renewable power to total power consumption (98% by 2030 and 111% by 2050), and CO2 emission reduction rates (70% by 2030 and 100% by 2050) and are more advanced than other districts in China. This planning scheme and method can provide a reference for the integrated energy planning of NCEDDs in developed urban areas.
Highlights
Strategic objectives were proposed during the 2015 United Nations Climate Conference in Paris which aimed to control the average global temperature within 2 ◦ C of pre-industrial levels and make substantial effort to control temperature increases within 1.5 ◦ C to achieve a peak of global greenhouse gas emissions (GHGs) as soon as possible, and achieve net-zeroGHGs during the second half of this century [1].a series of policies have been proposed by countries to achieve carbon neutrality by 2050
In order to contribute to the net-zero GHGs, China announced that peak CO2 emissions will be achieved by 2030 and that the nation will become as carbon neutral as possible by 2060 [5]
The planning strategies are formed as the overall principles of the planning approaches, which consist of reducing energy demand, applying renewable energy based on local resource conditions, and improving integrated energy efficiency through means such as thoroughly utilizing waste heat on the demand side
Summary
Strategic objectives were proposed during the 2015 United Nations Climate Conference in Paris which aimed to control the average global temperature within 2 ◦ C of pre-industrial levels and make substantial effort to control temperature increases within 1.5 ◦ C to achieve a peak of global greenhouse gas emissions (GHGs) as soon as possible, and achieve net-zeroGHGs during the second half of this century [1].a series of policies have been proposed by countries to achieve carbon neutrality by 2050. In order to contribute to the net-zero GHGs, China announced that peak CO2 emissions will be achieved by 2030 and that the nation will become as carbon neutral as possible by 2060 [5]. Tens of Chinese policies related to the reduction in carbon emissions, renewable energy, the electricity market, energy storage, etc., have been promulgated by various management departments from 2020 to 2021. One of these policies is called “Opinions of the Central Committee and the State Council on the complete, accurate and comprehensive implementation of the new development concept to achieve carbon peaking and carbon neutral”.
