據烴加工2021年7月29日報道，美國可再生柴油的生產能力到2024年可能顯著增加，這是基于幾個項目的宣布，這些項目要么正在建設中，要么即將開發。 這一增加是由各州和聯邦政府提高可再生燃料的目標、優惠的稅收抵免以及將現有的煉油廠轉變為可再生柴油煉油廠所推動的。

　　截至2020年底，美國可再生柴油生產能力總計近6億加侖/年，或3.8萬桶/天。 目前在建的幾個項目可能會使這一產能增加24億加侖/年; 已提議和已宣布的項目到2024年前將再增加18億加侖/年。 如果所有項目按計劃投產，到2024年底前，美國可再生柴油產量將達到51億加侖/年(33萬桶/天)。

　　盡管可再生柴油產量增長，但如果所有可再生柴油產能擴張的估計都能按計劃實現，而石油柴油煉油廠的產能基本保持不變，那么到2024年前，可再生柴油將占美國現有柴油總產能的5%左右。

　　可再生柴油是一種化學性質與石油柴油相同的可再生燃料，其性能特性幾乎相同。 可再生柴油可以在任何水平上混入石油柴油，這與生物柴油不同，生物柴油只能按2%至20%的體積比例混入柴油。

　　U.S. renewable diesel capacity could increase due to upcoming projects

　　U.S. production capacity for renewable diesel could increase significantly through 2024, based on several announcements for projects that either are currently under construction or could be in development soon. This growth is driven by higher state and federal targets for renewable fuel, favorable tax credits, and the conversion of existing petroleum refineries into renewable diesel refineries.

　　As of the end of 2020, U.S. renewable diesel production capacity totaled nearly 0.6 billion gallons per year (gal/y), or 38,000 barrels per day (b/d). Several projects currently under construction could increase this capacity by 2.4 billion gal/y; proposed and announced projects would add another 1.8 billion gal/y by 2024. If all projects come online as intended, U.S. renewable diesel production would total 5.1 billion gal/y (330,000 b/d) by the end of 2024.

　　Despite growth in renewable diesel production, renewable diesel will make up about 5% of current U.S. diesel production capacity by 2024 if all estimates of proposed renewable diesel capacity expansions occur as planned and petroleum diesel refinery capacity remains largely unchanged.

　　Renewable diesel is a renewable fuel that is chemically the same as petroleum diesel and nearly identical in its performance characteristics. Renewable diesel can be blended into petroleum diesel at any level, making it different from biodiesel, which can only be blended at rates between 2% and 20% of diesel fuel by volume
