煤炭与新能源融合发展，如何实现“1+1>2”

Core Viewpoint - The integration of coal and renewable energy is essential for achieving China's dual carbon goals while ensuring energy security, as demonstrated by the successful projects in Anhui Province [1][2][4]. Group 1: Project Overview - The first integrated demonstration project of "Photovoltaic + Coal Mining Subsidence Area" in Anhui covers 5,300 acres with 372,800 solar panels, showcasing a significant investment by Huaihe Energy [1]. - The first phase of the project has a capacity of 156,800 kW, while the second phase, currently under construction, will have a capacity of 243,200 kW [1]. - The project is expected to reduce carbon dioxide emissions by approximately 11.27 million tons over its operational period, equivalent to saving 4.23 million tons of standard coal [3]. Group 2: Industry Context - The coal industry remains a high-energy-consuming sector, and the electrification needs of mining operations provide natural scenarios for renewable energy applications [3]. - Huaihe Energy has reduced carbon emissions significantly, with CO2 emissions per unit of output decreasing by 27% in the coal sector and about 60% in the clean energy sector from 2020 levels [2]. Group 3: Technological Integration - The integration of coal and renewable energy is seen as a key component in building a new energy system, where non-fossil energy serves as the main supply and fossil energy acts as a backup [4]. - Huaihe Energy's clean and efficient coal power units, which account for over 90% of its capacity, can be flexibly modified to work alongside solar and wind energy, enhancing energy system stability [4]. Group 4: Multi-Energy System Development - Various regions are exploring feasible paths for integrating coal and renewable energy, with examples including the multi-energy integration approach in Shaanxi and the comprehensive development in Guizhou [5]. - Huaihe Energy has developed a multi-faceted clean energy system that includes photovoltaic, wind, gas power, and energy storage [8]. Group 5: Policy and Technical Challenges - Despite progress, challenges remain in policy implementation and technological innovation, particularly in local execution of national policies and the complexity of approval processes [9]. - Experts suggest that companies should engage with local planning and that governments need to establish fair resource distribution mechanisms to reduce competition among enterprises [9]. Group 6: Future Directions - Companies are encouraged to adopt a long-term perspective, investing in renewable energy to build core competitiveness and create new value through ecological restoration and carbon asset management [10]. - Huaihe Energy aims to implement a zero-carbon park integrating wind, solar, storage, and charging facilities, revitalizing traditional coal bases [10].
