“深耕”可持续，真正“接地气”——华晨宝马地热项目创造能源转型新范本

Core Viewpoint - The Huachen BMW geothermal energy project represents a significant advancement in BMW Group's long-standing commitment to clean energy and sustainability, showcasing the collaborative vision of Chinese and German enterprises in sustainable development [2][17]. Group 1: Project Overview - The Huachen BMW geothermal energy project commenced operations on October 31, enabling the powertrain factory to achieve 100% non-fossil energy heating, with an expected annual carbon reduction of 18,000 tons, thereby lowering the carbon footprint of BMW's "New Generation" models from the source [4][8]. - This project is part of BMW's extensive sustainability efforts over the past 50 years, marking a breakthrough in their commitment to environmental protection and sustainable practices [5][17]. Group 2: Technological Innovation - The project involves drilling 28 deep geothermal wells to a depth of approximately 2,900 meters, utilizing a "heat extraction without water" method, which enhances environmental protection while ensuring stable and efficient geothermal energy collection [9][11]. - The innovative approach of using coaxial heat exchangers for thermal exchange with underground rock layers represents a significant advancement in geothermal energy utilization, particularly in the context of China's automotive industry [11][12]. Group 3: Collaborative Efforts - The project is a collaborative effort involving Huachen BMW, China Huaneng Group, Wanjing New Energy Co., Ltd., and Shenyang Sino-German Development Zone Construction Group, with the Shenyang municipal government providing crucial support [12][14]. - The project employs a contract energy management model, allowing for shared investment, construction, and operation among the partners, which enhances its commercial sustainability [12][14]. Group 4: Future Potential - BMW plans to expand geothermal energy applications in its factories and potentially throughout the Shenyang Iron West District, with expectations of further reducing costs while achieving 100% non-fossil energy heating [14][16]. - The project serves as a model for clean energy applications in industrial regions, providing valuable insights for broader adoption of geothermal energy in similar contexts [12][17].
