日企将用深层地热等新技术为AI供电

Core Viewpoint - The article discusses the advancements in geothermal power generation technology, highlighting the efforts of companies like Eavor and Quaise Energy in developing next-generation geothermal power plants in Germany, Japan, and Asia, which can tap into deeper underground heat sources for energy production [1][2]. Group 1: Technological Advancements - Eavor and other companies are constructing next-generation geothermal power plants that can extract heat from over 2000 meters underground, expanding the potential for geothermal energy development beyond traditional locations like hot springs and national parks [1]. - The new technology allows for the injection of water into underground areas lacking natural hot water or steam, making it easier to avoid depletion of hot springs and potentially lowering operational costs [1][2]. - Quaise Energy's method involves injecting water into fractured underground rock layers, achieving a power generation capacity of 25,000 to 40,000 kilowatts, which can be up to ten times larger than traditional geothermal systems [2]. Group 2: Market Potential and Government Support - Japan has over 77 million kilowatts of potential geothermal resources available for the new technology, which is more than three times that of traditional geothermal resources [2]. - The Japanese government plans to promote next-generation geothermal power by the 2030s and is discussing necessary support policies [2]. - The cost of geothermal power generation in Japan is competitive, with costs ranging from 16.1 to 16.8 yen per kilowatt-hour, similar to onshore wind power [3]. Group 3: Future Projections - The International Energy Agency (IEA) predicts that global geothermal power capacity will increase from approximately 15 million kilowatts in 2023 to around 800 million kilowatts by 2050 [3]. - In the United States, the installed capacity is expected to reach about 4 million kilowatts by 2024, indicating that only about 10% of the geothermal resource potential is currently utilized [3].
