美国EPA建议的碳排放法规，会在清洁能源计划失败的地方取得成功吗？

报告概要

2023年5月8日，美国EPA建议了对煤炭及天然气发电厂的新碳排放标准。新标准，是否导入碳回收技术(CCUS)，基于使用氢燃料，削减减少排放的发电机组，在围栏内采取从源头减少排放的措施。虽然EPA提出的指导方针可以加速减排并刺激对新技术的需求，但能源向更清洁、低排放或零排放发电的转变已经在顺利进行。时间将证明美国环保署这次能否克服法律挑战，以便为电力产业实施持久的碳排放标准。

目录

• 主要的规定
• 应该留心希望的内容
• 无论有没有指导方针，煤炭和碳排放量都会大幅下降
• 市场类型很重要
• CCUS可行性的核心设备使用率
• 促进低温室效应气体的氢需求的政策的冰山一角
• 第3次是魅力吗？

Report Summary:

On 8 May 2023, the US EPA proposed new carbon emission standards for coal and natural gas power plants. The new standards are based on generating units installing carbon capture technology (CCUS) or using hydrogen fuel to reduce their emissions-inside the fenceline measures to reduce emissions at the source. While the EPA proposed guidelines could accelerate emission reductions and spur demand for new technologies, the energy transition to cleaner, low- or zero-emission generation is already well underway. Time will tell whether the EPA can overcome legal challenges this time around in order to implement lasting carbon emission standards for the power sector.
