Hydrogen and coal power plants carbon capture rate in North America by location 2022

As of May 2022, none of the selected blue hydrogen developers in North America had achieved the promised carbon capture rate of 95 percent. The Quest, Alberta carbon capture and storage (CCS) facility developed by Shell is the one with the highest carbon capture rate, between 77 and 83 percent of the carbon dioxide from operation, transport, and storage of the hydrogen units. By comparison, the Air Products facility in Port Arthur, Texas has a CCS system that captured less than 50 percent of the carbon dioxide generated by the hydrogen production units. CCS technologies involve capturing CO2 emitted from the burning of fossil fuels or from other industrial processes and sequestering the CO2 in underground storage facilities.

截至2022年5月，北美所选定的蓝色氢能开发者中，尚无一家能够达到承诺的95%碳捕集率。由壳牌开发的阿尔伯塔省碳捕集与封存（CCS）设施——Quest，是碳捕集率最高的，其碳捕集率介于氢能单元操作、运输和储存过程中产生的二氧化碳的77%至83%之间。相比之下，德克萨斯州波涛市的Air Products设施所配备的CCS系统捕获的二氧化碳比例不足50%。CCS技术涉及从化石燃料燃烧或其他工业过程中排放的二氧化碳中捕获CO2，并将其封存于地下储存设施中。
