2、tion of fossil energy.CCUS 是目前实现化石能源低碳化利用的唯一技术选择。It is estimated that by 2050,fossil energy will account for 10%-15%of Chinas energyconsumption.到2050 年，化石能源仍将扮演重要角色，占中国能源消费比例的10%15%。CCUS can maintain the flexibility of power system to realize carbon neutrality.CCUS 是碳中和目标下保持电力系统灵活性的主要技术手段。By avoid a

3、n early phasing out of coal-fired power stations,the necessary support forsystem inertia and frequency control is then guaranteed when facing the great volatilityof renewable energy and potential seasonal power shortages.火电加装CCUS是具有竞争力的重要技术手段，可实现近零碳排放，提供稳定清洁低碳电力，平衡可再生能源发电的波动性，并在避免季节性或长期性的电力短缺方面发挥惯性支

4、撑和频率控制等重要作用。4(1)Importance of CCUS 碳捕集、利用与封存技术的定位CCUS is a feasible technology option for hard-to-abate sectors,like steel and cement.CCUS 是钢铁水泥等难以减排行业低碳转型的可行技术选择。After implementing measures like efficiency improvement,raw material substitution,and etc,it is estimated that 34%of carbon emissions in

5、the steel industry and 48%ofcarbon emissions in the cement industry are hard to abate.预计到2050年，钢铁行业通过采取工艺改进、效率提升、能源和原料替代等常规减排方案后，仍将剩余34%的碳排放量，即使氢直接还原铁(DRI)技术取得重大突破，剩余碳排放量也超过8%。水泥行业通过采取其他常规减排方案后，仍将剩余48%的碳排放量。CCUS coupled with renewable energy could realize negative emissions.CCUS 与新能源耦合的负排放技术是实现碳中和目标

6、的重要技术保障。CCUS coupling with bio-energy,usually referred to as BECCS,could realize negativeemssions.Negative emission technologies can neutralize greenhouse gas emissions andprovide important support for achieving the goal of carbon neutrality.BECCS及其他负排放技术可中和该部分温室气体排放，推动温室气体净零排放，为实现碳中和目标提供重要支撑。Source
