二氧化碳截住儲埋

**二氧化碳截住同儲埋**（簡寫做**碳截儲**，**CCS**）即係捉實啲大型發電廠產生嘅二氧化碳（CO2），然後用各種辦法儲起佢，唔畀佢出大氣層。碳截儲係調慢全球變暖嘅一個方法，商業用大型二氧化碳截住嘅方法已經用咗一段時間，好成熟。將二氧化碳渚入地層係做過吓，不過，要長期咁儲埋二氧化碳只係一個未實踐嘅諗頭。到而家（2007年）為止，未有一間投產嘅電廠安裝咗碳截儲嘅設施。

有碳截儲設施嘅電廠，比起冇嘅廠，排少八到九成嘅二氧化碳，而有減排設施嘅電廠運行嗰時，大約用多兩到九成嘅能源，呢個只限於新起、近住儲埋地點嘅廠，如果現成嘅電廠加減排設施會重貴。

一係將啲二氧化碳㘉入地下岩層，深海。或者變成碳酸礦物。深海儲埋會搞到海洋酸化。儲埋喺地下岩層而家係最理想同可行嘅方法，現有嘅地點估計可以至少儲 2000 Gt 嘅 CO2（而家人類每年整 30 Gt 嘅 CO2 出嚟）。
