A makwaara okwu carbon capture na nchekwa dị ka carbon dioxide capture na storage. Nkọwa maka okwu a bụ: "A usoro nke a na-ekewapụta carbon dioxide (CO2) dị ọcha site na ụlọ ọrụ mmepụta ihe na isi mmalite metụtara ike (ejide), tinye ya, tinye ya ma buru ya gaa ebe nchekwa maka nnọpụiche dị ogologo oge site na ikuku". Okwu na echiche metụtara bioenergy na carbon njide na nchekwa a maara na bekee di ka bioenergy with carbon capture and storage (BECCS) na mwepụ carbon dioxide (nke a na-akpọkwa mgbapụta na-adịghị mma).
