Ukubanjwa kwekhabhoni, ukuGcina iKhabhoni, ukuSetyenziswa kweKhabhoni: Imodeli entsha yokuncitshiswa kwekhabhoni ngeteknoloji

Itekhnoloji yeCCUS inokuxhobisa ngokunzulu amasimi ahlukeneyo. Kwintsimi yamandla kunye namandla, ukudibanisa "amandla okushisa + CCUS" kukhuphisana kakhulu kwinkqubo yamandla kwaye inokufikelela ukulingana phakathi kophuhliso lwekhabhoni ephantsi kunye nokusebenza kakuhle kokuveliswa kwamandla. Kwintsimi yoshishino, iteknoloji ye-CCUS inokukhuthaza ukuguqulwa kwekhabhoni ephantsi kumashishini amaninzi akhuphayo kunye nobunzima bokunciphisa, kunye nokubonelela ngenkxaso yobugcisa ekuphuculweni kwezoshishino kunye nophuhliso lwekhabhoni ephantsi kumashishini asebenzisa amandla emveli. Ngokomzekelo, kwishishini lensimbi, ngaphezu kokusetyenziswa kunye nokugcinwa kwe-carbon dioxide ebanjwe, inokusetyenziswa ngokuthe ngqo kwinkqubo yokwenza insimbi, enokuphucula ngakumbi ukusebenza kokunciphisa ukukhutshwa. Kwishishini lesamente, ukukhutshwa kwekhabhoni dioksidi ukusuka ekubolisweni kwe-akhawunti ye-limestone malunga ne-60% yokukhutshwa okupheleleyo kweshishini le-samente, iteknoloji yokubamba i-carbon dioxide inokubamba i-carbon dioxide kwinkqubo, yindlela yobugcisa efunekayo yokuchithwa kwe-samente. ishishini. Kwishishini le-petrochemical, i-CCUS inokufezekisa zombini imveliso yeoli kunye nokunciphisa i-carbon.

Ukongeza, itekhnoloji yeCCUS inokukhawulezisa uphuhliso lwamandla acocekileyo. Ngokuqhushumba kweshishini lamandla e-hydrogen, i-fossil energy imveliso ye-hydrogen kunye ne-CCUS iteknoloji iya kuba ngumthombo obalulekileyo we-hydrocarbon ephantsi ixesha elide kwixesha elizayo. Okwangoku, imveliso yonyaka yezityalo ezisixhenxe zokuvelisa i-hydrogen eziguqulwe ngeteknoloji ye-CCUS emhlabeni iphezulu njengeetoni ezingama-400,000, eziphindwe kathathu zokuveliswa kwe-hydrogen yeeseli ze-electrolytic. Kwakhona kulindeleke ukuba i-2070, i-40% yemithombo ye-hydrocarbon ephantsi yehlabathi iya kuvela "kwi-fossil energy + CCUS technology".

Ngokweenzuzo zokunciphisa ukukhutshwa, iteknoloji ye-CCUS 'negative carbon inokunciphisa iindleko ezipheleleyo zokuphumeza ukungathathi hlangothi kwekhabhoni. Kwelinye icala, itekhnoloji ye-CCUS 'negative carbon ibandakanya ukubanjwa nokugcinwa kwe-biomass energy-carbon (BECCS) kunye nokubanjwa kwekhabhoni yomoya ngqo kunye nokugcinwa (DACCS), ethi ibambe ngokuthe ngqo ikharbon diokside kwinkqubo yokuguqulwa kwamandla ebhayomass kunye nomoya, ngokulandelelanayo, ukufikelela kwi-decarbonization enzulu ngexabiso eliphantsi kunye nokusebenza okuphezulu, ukunciphisa iindleko ezicacileyo zeprojekthi. Kuqikelelwa ukuba i-decarbonization enzulu yecandelo lamandla ngokusebenzisa i-biomass energy-carbon capture (BECCS) ubuchwepheshe kunye ne-air carbon capture (DACCS) ubuchwepheshe buya kunciphisa iindleko zotyalo-mali ezipheleleyo zeenkqubo ezikhokelwa ngamandla ahlaziyekayo kunye nokugcinwa kwamandla ngama-37% ukuya kuma-48. %. Ngakolunye uhlangothi, i-CCUS inokunciphisa umngcipheko wee-asethi ezinqamlekileyo kunye nokunciphisa iindleko ezifihliweyo. Ukusebenzisa itekhnoloji ye-CCUS ukuguqula isiseko semizi-mveliso esifanelekileyo sinokuqonda ukusetyenziswa kwekhabhoni ephantsi yeziseko zamandla efosili kunye nokunciphisa iindleko ezingasebenziyo zezibonelelo phantsi komqobo wokukhutshwa kwekhabhoni.
