1. **胺基燃烧后捕集(PCC)是唯一可行技术**:当前大型NGCC电厂脱碳仅依赖胺基PCC,其他技术(如Allam循环、固体吸附剂)因不成熟或低浓度烟气限制暂不可行。 2. **捕集成本敏感度高**:成本随负荷因子变化显著,高负荷时约80美元/吨CO₂,低负荷时超212美元/吨;2020-2024年通胀与利率上升导致成本激增59%。 3. **捕集率目标提升**:传统90-95%基准已被突破,研究证实可实现近100%“新增CO₂”捕集(如广东平台测试)。 4. **灵活性是关键**:英国FOCUSS项目证明溶剂存储系统可保障启停及变负荷时高捕集率,中国华能洋浦试点(2000吨/年)验证了灵活运行。 5. **中英战略需求**:中国2030年气电容量或达200-400GW,英国目标2035年电力净零,NGCC+CCUS是电网稳定的核心过渡技术。
气电如何脱碳? 捕碳成本有多高? 灵活运行可行吗?
