Ubuchwepheshe be-CCUS bunganika amandla ngokujulile izinkambu ezahlukahlukene. Emkhakheni wamandla namandla, inhlanganisela "yamandla ashisayo + CCUS" inokuncintisana kakhulu ohlelweni lwamandla futhi ingafinyelela ukulingana phakathi kokuthuthukiswa kwekhabhoni ephansi nokusebenza kahle kokukhiqizwa kwamandla. Emkhakheni wezimboni, ubuchwepheshe be-CCUS bungagqugquzela ukuguqulwa kwekhabhoni ephansi yezimboni eziningi ezikhipha umoya ongcolile nezinzima ukunciphisa, futhi zinikeze ukusekelwa kwezobuchwepheshe ekuthuthukisweni kwezimboni kanye nokuthuthukiswa kwekhabhoni ephansi yezimboni zendabuko ezisebenzisa amandla. Isibonelo, embonini yensimbi, ngaphezu kokusetshenziswa nokugcinwa kwe-carbon dioxide ebanjiwe, ingasetshenziswa futhi ngokuqondile kwinqubo yokwenza insimbi, engakwazi ukuthuthukisa ukusebenza kahle kokunciphisa ukukhishwa. Embonini kasimende, ukukhishwa kwe-carbon dioxide ekuwohlokeni kwe-akhawunti ye-limestone cishe kwe-60% yengqikithi yokukhishwa kwemboni kasimende, ubuchwepheshe bokuthwebula i-carbon bungabamba i-carbon dioxide kule nqubo, kuyindlela yobuchwepheshe edingekayo ukuze kukhishwe i-carbonization kasimende. imboni. Embonini ye-petrochemical, i-CCUS ingafinyelela kokubili ukukhiqizwa kukawoyela kanye nokunciphisa i-carbon.
Ngaphezu kwalokho, ubuchwepheshe be-CCUS bungasheshisa ukuthuthukiswa kwamandla ahlanzekile. Ngokuqhuma kwemboni yamandla e-hydrogen, ukukhiqizwa kwe-hydrogen yamandla ezinto ezimbiwa phansi kanye nobuchwepheshe be-CCUS kuzoba umthombo obalulekile we-hydrocarbon ephansi isikhathi eside esikhathini esizayo. Njengamanje, umkhiqizo wonyaka wezitshalo eziyisikhombisa zokukhiqiza i-hydrogen okuguqulwa ubuchwepheshe be-CCUS emhlabeni uphakeme ngamathani angu-400,000, okuphindwe kathathu ukukhiqizwa kwe-hydrogen yamaseli e-electrolytic. Kulindeleke futhi ukuthi ngo-2070, i-40% yemithombo ephansi ye-hydrocarbon emhlabeni izovela "ku-fossil energy + CCUS technology".
Mayelana nezinzuzo zokunciphisa ukungcola, ubuchwepheshe be-CCUS 'negative carbon bunganciphisa izindleko eziphelele zokuthola ukungathathi hlangothi kwekhabhoni. Ngakolunye uhlangothi, ubuchwepheshe be-CCUS 'negative carbon technologies buhlanganisa i-biomass energy-carbon capture and storage (BECCS) kanye ne-direct air carbon capture and storage (DACCS), ebamba ngokuqondile i-carbon dioxide enqubweni yokuguqulwa kwamandla e-biomass kanye nomkhathi, ngokulandelana, ukuze ukufeza i-decarbonization ejulile ngezindleko eziphansi kanye nokusebenza kahle okuphezulu, ukunciphisa izindleko ezicacile zephrojekthi. Kulinganiselwa ukuthi ukuchithwa okujulile komkhakha wamandla ngobuchwepheshe bokuthwebula i-biomass energy-carbon (BECCS) kanye nobuchwepheshe bokubanjwa kwekhabhoni yomoya (DACCS) kuzonciphisa izindleko eziphelele zokutshalwa kwezimali zezinhlelo eziholwa amandla avuselelekayo avuselelekayo kanye nokugcinwa kwamandla ngama-37% ukuya kuma-48. %. Ngakolunye uhlangothi, i-CCUS inganciphisa ubungozi bempahla eboshiwe futhi inciphise izindleko ezifihliwe. Ukusebenzisa ubuchwepheshe be-CCUS ukuguqula ingqalasizinda yezimboni efanele kungabona ukusetshenziswa kwekhabhoni ephansi kwengqalasizinda yamandla ensalela phansi futhi kunciphise izindleko zokungenzi lutho zezindawo ngaphansi komkhawulo wokukhishwa kwekhabhoni.
