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, particularly the "Photovoltaic + Coal Mining Subsidence Area" initiative by Huaihe Energy [1][2][4] Group 1: Project Overview - The first integrated demonstration project in Anhui features 373,000 photovoltaic panels over 5,300 acres in a coal mining subsidence area, with a total installed capacity of 40,000 kilowatts across two phases [1] - The first phase has an operational capacity of 156,800 kilowatts, while the second phase, currently under construction, will have a capacity of 243,200 kilowatts [1] Group 2: Environmental Impact - The photovoltaic project is expected to reduce carbon dioxide emissions by approximately 11.27 million tons during its operational period, equivalent to saving 4.23 million tons of standard coal [3] - The first phase of the photovoltaic power station has generated 440 million kilowatt-hours of electricity, meeting the annual electricity needs of over 200,000 households and saving about 131,400 tons of standard coal, resulting in a reduction of approximately 340,000 tons of carbon dioxide emissions [6] Group 3: Industry Trends - The integration of coal and renewable energy is seen as a critical step in building a new energy system, where non-fossil energy serves as the main supply and fossil energy acts as a backup [4] - The coal industry, traditionally high in energy consumption, is now leveraging its electrification needs to create natural scenarios for renewable energy applications [3] Group 4: Technological and Policy Challenges - Despite progress, challenges remain in policy implementation and technological innovation, particularly in local regulations and subsidy disbursement affecting investment enthusiasm [9] - There is a call for increased investment in foundational research to overcome technical challenges related to low-concentration gas utilization and geothermal energy development [9][10] Group 5: Future Directions - Companies are encouraged to adopt a long-term perspective, prioritizing investments in renewable energy to cultivate core competitiveness and drive ecological restoration and carbon asset management [10] - Huaihe Energy aims to implement an integrated zero-carbon park model that combines wind, solar, storage, and charging facilities, revitalizing traditional coal bases [10]
