美國EPA建議的碳排放法規，會在清潔能源計劃失敗的地方取得成功嗎？

報告概要

2023年5月8日，美國EPA建議了對煤炭及天然氣發電廠的新碳排放標準。新標準，是否導入碳回收技術(CCUS)，基於使用氫燃料，削減減少排放的發電機組，在圍欄內採取從源頭減少排放的措施。雖然EPA提出的指導方針可以加速減排並刺激對新技術的需求，但能源向更清潔、低排放或零排放發電的轉變已經在順利進行。時間將證明美國環保署這次能否克服法律挑戰，以便為電力產業實施持久的碳排放標準。

目錄

• 主要的規定
• 應該留心希望的內容
• 無論有沒有指導方針，煤炭和碳排放量都會大幅下降
• 市場類型很重要
• CCUS可行性的核心設備使用率
• 促進低溫室效應氣體的氫需求的政策的冰山一角
• 第3次是魅力嗎？

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.
