地热能是一种绿色低碳、可循环利用的可再生能源。开发利用地热能对于调整能源结构、节能减 排、改善环境具有重要意义。 陕西地热资源优势明显。咸阳水温、水质、水量等资源条件得天独厚，是全国首座"中国地热城"， 被国家发展改革委确定为"国家地热资源综合开发利用示范区"。 11月21日，记者走进我国首个"热电氦"联产先导性试验项目、陕西首个地热发电实验项目——中石 化新星绿源陕西公司"热电氦"联产先导性试验项目现场，探访咸阳如何专业化开发、规模化利用地热 能。 在咸阳宝石佳苑小区，项目的一口深达3000米的地热井正源源不断地输送着热水。这些热水经过热 交换系统后，可为17万平方米的区域清洁供暖。 能。 氦气提取是该项目的又一成果。氦气是重要战略资源，被称为"黄金气体"，广泛应用于航空航天、 医疗、工业等领域。"项目地热井的氦气含量较高，超过了2.6%。"张献喻说，在氦气的提取上，项目通 过膜分离和变压吸附耦合工艺，可获得纯度超99.999%的氦气。 "总体来说，氦气提取、地热能发电与地热能供暖互为补充，'三位一体'。多项技术集成让项目实 现了供暖、发电、战略资源提取的多重效益，对于延伸地热能产业链、优化能源结构具有积极 ...

Core Viewpoint - The recently passed Republican budget bill in the Senate eliminates tax credits for renewable energy projects, which could significantly impact the solar and wind energy industries and lead to increased utility bills for American households [1][5][14]. Legislative Process - The Senate passed the bill with a narrow margin of 51 votes in favor and 50 against, with Vice President JD Vance casting the deciding vote [1]. - The bill has been sent to the House of Representatives for final legislative approval, where it cleared procedural hurdles with a vote of 219 to 213 [2]. Tax Implications - The final version of the bill retains some incentives for advanced nuclear, geothermal, and hydropower technologies until 2032, but it significantly reduces incentives for solar and wind energy projects [8]. - The bill allows full tax credits for wind and solar projects that commence within one year of the law's enactment, with a deadline for completion set for the end of 2027 for projects starting later [7]. Industry Reactions - The American Petroleum Institute welcomed the bill, viewing it as a historic piece of legislation that opens up investment opportunities and expands access to oil and gas development [6][7]. - Conversely, the Solar Energy Industries Association expressed concerns that the bill would undermine the recovery of American manufacturing and lead to higher utility bills for families, factory closures, and increased unemployment [5][14]. Political Perspectives - Republican senators argue that the bill will save taxpayers money and support traditional energy sources, while Democrats criticize it as destructive and harmful to the healthcare system and the environment [10][11][12]. - Some Republican senators, like Lisa Murkowski, acknowledged the difficult decision-making process regarding the bill, emphasizing the need to consider the interests of their constituents [9][10].
