To decarbonize Canada’s heavy oil and oil sands operations, we propose replacing natural gas as fuel by hydrogen, which can be produced by steam methane reforming with carbon capture and storage (CCS). Results show that using hydrogen as fuel in 162 heavy oil and oil sands projects in Canada would save 1.5 trillion cubic feet per year of natural gas between 2021 and 2050. This amount of natural gas can produce 15.2 million ton per year of blue hydrogen by steam methane reforming, of which only 12.6 million ton per year is needed in Canada’s heavy oil and oil sands operations, resulting in 76% reduction in CO₂ emissions. Furthermore, implementing CCS at a capacity of 105 million ton per year is proposed for Central Alberta. Using blue hydrogen as fuel in the heavy oil and oil sands operations is profitable when Canada’s carbon tax reaches $99 per ton in 2027.

使用蓝色氢对加拿大的重油和油砂作业进行脱碳

为了使加拿大的重油和油砂作业脱碳，我们建议用氢气代替天然气作为燃料，氢气可以通过碳捕获和储存 (CCS) 的蒸汽甲烷重整生产。结果表明，在加拿大的 162 个重油和油砂项目中使用氢作为燃料，从 2021 年到 2050 年，每年将节省 1.5 万亿立方英尺的天然气。这一数量的天然气每年可以通过蒸汽生产 1520 万吨蓝色氢甲烷重整，其中加拿大重油和油砂作业每年仅需 1260 万吨，可减少 76% 的 CO ₂排放。此外，建议在艾伯塔省中部以每年 1.05 亿吨的能力实施 CCS。当加拿大的碳税在 2027 年达到每吨 99 美元时，在重油和油砂作业中使用蓝色氢作为燃料是有利可图的。
