Amanyathelo okudala iitonela zero-carbon

Ngaphandle kwexesha eloyikisayo elimiselwe yi-Paris Accord, iitonela ze-zero-carbon zinokufikeleleka ukuba izisombululo ezifanelekileyo ziphunyeziwe.

Umzi-mveliso we-tunneling ukwindawo yokuncamisa apho uzinzo kunye ne-decarbonisation ziphezulu kwii-ajenda zabaphathi. Ukufezekisa i-1.5 ° c ekujoliswe kuyo kutshintsho lwemozulu ngo-2050, ishishini lokuthungatha kuya kufuneka linciphise ukukhutshwa kwe-CO2 ngokuthe ngqo kwi-net zero.

Okwangoku ambalwa kakhulu amazwe kunye neeprojekthi zeziseko ezingundoqo "zihamba intetho" kwaye zithatha inyathelo lokunciphisa ikhabhoni. Mhlawumbi iNorway lilizwe elinye elihamba phambili, kwaye, njengoko kunye nemarike yabo yemoto yombane yasekhaya, izixhobo zokwakha zombane zombane zisanda kuqashwa, kunye nezixeko ezinkulu ezinokwakhiwa kwe-carbon neutral ngo-2025. Ngaphandle kweNorway, amazwe ambalwa kunye neeprojekthi eYurophu ngokomzekelo. , baseka ubuncinane iithagethi ezinqwenelekayo zokunciphisa i-carbon, kodwa ngokuqhelekileyo kuphela ngokugxila ekuphuhliseni imixube ye-carbon concrete ephantsi.

Ishishini le-tunneling linegalelo ekukhutshweni kwe-CO2 yehlabathi kwaye linendima yokudlala ekunciphiseni i-carbon. Ishishini lijongene noxinzelelo olwandayo oluvela kubenzi bemigaqo-nkqubo, abatyali-mali, kunye nabathengi ukuba benze imisebenzi ye-decarbonise.

Emva kokuba isigqibo sithathiweyo sokwakha itonela elitsha, uyilo olukrelekrele olulandelwa kulwakhiwo olusebenzayo olugxile kwikhabhoni luya kuthi ekugqibeleni lukhokelele kwiindleko zeprojekthi eziphantsi.

Ngelixa abanye bekholelwa ukuba itonela yekhabhoni ephantsi ilingana neendleko eziphezulu zeprojekthi, eyona ndlela isebenzayo ngoku yolawulo lwekhabhoni kwishishini lokwakha icebisa ngenye indlela, kwaye ngendlela ebanzi kubo bonke ubomi beprojekthi, kunye neenjineli ezigxile ekugcinweni kwekhabhoni, oku kuzisa ngokwangaphakathi ukonga iindleko zeprojekthi. kwakhona! Ngokuqinisekileyo le yimfundiso esemva kwePAS2080 eqhelekileyo kuLawulo lweCarbon kwiZiseko zoPhuhliso kwaye kufanelekile ukuqeshwa kwiiprojekthi zabo banomdla kwi-decarbonisation.

Ngenxa yolu sukelo lukhulayo kunye nesidingo se-decarbonisation, nazi iisenti zam ezintlanu: imiba emithathu engundoqo enokukhawulezisa iinzame ze-decarbonation kwaye yenze ukuqhubela phambili okubonakalayo ekufezekiseni injongo yokutshintsha kwemozulu nge-1.5°C ‒ Yakha ubuhlakani, ukwakha ngokufanelekileyo, kwaye wakhele indawo ubomi bonke.

Yakha ngobukrelekrele-Yonke into iqala ngoyilo oluyilayo nolucingelayo

Eyona nzuzo inkulu ye-decarbonisation kwitonela ivela kwizigqibo kwizigaba zokucwangcisa kunye noyilo. Ukhetho lwangaphambili lweeprojekthi ezinokwenzeka lubalulekile kwibali lekhabhoni, kubandakanywa nokuba kwakhiwe konke, okanye ukujonga ukuphucula okanye ukwandisa ubomi be-asethi ekhoyo ngaphambi kokulandela indlela entsha yokwakha.

Ngoko, kusekuqaleni kwinqanaba lokuyila ukuba ulwahlulo oluphambili lwenziwe, kwaye kwiitonela kuyilo apho umlinganiselo omkhulu wokonga kwikhabhoni unokwenziwa. Olo ncedo loyilo lunokuphunyezwa ngokulula kwiiprojekthi zetonela ngokusebenzisa ubunkokheli babathengi, umzekelo ukukhuthaza iindlela zokuthengwa kwempahla ezitsala iikontraka eziphambili ukuba zibonelele ngeenkqubo ezintsha zokunciphisa ikhabhoni kunye nemathiriyeli, ezithi nazo zivuselele ikhonkco lobonelelo lobugcisa olubanzi.

Kwitonela yobuso obuvulekileyo, inkxaso yamatye ekhonkrithi etshiziweyo isetyenziswa kwihlabathi jikelele, kwaye kumazwe amaninzi ehlabathi, ngenxa yomgangatho wayo ophakamileyo, iye yamkelwa ngokubanzi kwitonela esisigxina, egcina phakathi kwe-20-25% yekhonkrithi esetyenziswa kwitonela yesiqhelo. iinkqubo zelinen. Ndiyakholelwa ukuba iinkqubo zekhonkrithi ezitshiziweyo namhlanje, ezidibanisa amanqanaba aphezulu ePortland Cement replacement, iintsinga zepolymer kunye nobuchwepheshe obutsha bokuthintela amanzi, zibonelela ngamathuba okufezekisa ngaphezulu kwe-50% yokuncipha kwekhabhoni kwilinen yethu yetonela. Kodwa kwakhona, ezi zisombululo 'Zakha uBukrelekrele' kufuneka zibanjwe kwaye ziphunyezwe kwinqanaba loyilo lokuqala ukuze kwandiswe amandla amakhulu okugcina ikhabhoni. Ezi zizisombululo zokwenyani zokunika ulondolozo lokwenyani, kwaye singenza la manyathelo makhulu namhlanje ngenkcubeko yeqela elilungileyo, uyilo oluchanekileyo, kunye nokudityaniswa neemodeli ezintsha ezinomdla zokuthenga ezinyanzela izinto ezakhayo ukuba zenzeke.

Njengecala elingunote, umceli mngeni kwikhabhoni ephantsi etshizwe ikhonkrithi yinzuzo yamandla ecothayo kwiiyure ezimbalwa zokuqala emva kokutshiza. Ukuzuza amandla kwangethuba kubalulekile kukhuseleko oluphezulu kunye nemveliso ekwakheni iileya ezishinyeneyo ngokwaneleyo. Izifundo ezinomdla eziye zaphuhliswa kunye ne-geopolymers (imixube engenazo i-samente yasePortland) ibonise ukuba sinokufumana ikhonkrithi ye-ultra-low carbon kunye nokuzuza ngokukhawuleza kwamandla okuqala, nangona siqhubeka nokuphucula ukusebenza kwexesha elide elifunekayo ukwenza le mixube isebenze ngakumbi.

Inyathelo elilandelayo esinokulithatha ukuya kwiitonela ze-carbon zero kukusebenza ngokugqwesileyo kuzo zonke iinkqubo zokwakha.

Ugqaliselo lwakwangoko - ubuhlakani bobuchule kuyilo kunye nentsebenziswano kunye neekontraka kunye nekhonkco lokubonelela.

Izinto ezisezantsi kunye nekhabhoni ephantsi etshizwe ngekhonkrithi. Ii-accelerator ezintsha kunye ne-membrane zingundoqo.

Uqeqesho lokulinganisa, ukuvunywa kwe-EFNARC, ukuphuculwa okuqhubekayo, ukuphuhlisa ngakumbi ukutshiza okuncediswa yikhompyutha.

Abantu bangundoqo ekwenzeni itonela ye-carbon SCL ephantsi. Ayizukuvela kumthetho karhulumente. Abaqhubi bezicwangciso kufuneka bakhokele.

Indlela ebanzi yoyilo lwetonela kunye nolwakhiwo iyafuneka ukuze kuhlaziywe ushishino. Inyathelo ngalinye lenkqubo libonelela ngecandelo elibalulekileyo lokonga ikhabhoni.

Yakha ngokufanelekileyo - Izixhobo ezihlakaniphile, abantu kunye nedijithali

Kuya kufuneka iinzame ezininzi ukujongana nemithombo ephambili yokukhutshwa kwezinto ezikhutshwayo kunye nokunciphisa i-carbonise. Amanyathelo anjalo aquka inyathelo elibhekisele ekufumaneni izinto ngokuzinzileyo, ukusetyenziswa kwamafutha okufudumeza okukhethiweyo, oololiwe bombane, kunye nokutshintshela kubaboneleli bombane oluhlaza ukunika amandla iiprojekthi zethu zokwakha itonela.

Umzekelo wonikezelo lwethu oluzinzileyo ziimoto zethu zombane zebhetri yeSmartDrive. I-SmartDrive ibonelela ngentsebenzo ephuculweyo ngokukhutshwa kwe-zero kwasekhaya. Bakwaphelisa iindleko zokuthutha amafutha kunye nepetroli kwaye baneendleko eziphantsi zokulungisa izixhobo. Ngokomzekelo, iikontraki zaseNorway sele zisebenza kwiithagethi ze-2050 ze-carbon net zero ngokusebenzisa i-SmartDrive Spraymec 8100 SD iirobhothi zokutshiza zihlawuliswa ngokusebenzisa umbane wegridi yombane. Sikwaqala ukukubona oku kwiiprojekthi zemigodi ezikude apho amaziko ombane ahlaziyekayo asemgodini abonelela ngamandla okutshaja ibhetri kwinqanawa yezixhobo zemigodi. Le yi-zero enetha kwaye i-2050 ilungile.

Okubaluleke kakhulu ekuncitshisweni kwekhabhoni kukuqala ukulinganisa kunye nokuseka ukusetyenziswa kwekhabhoni kwiiprojekthi zokuhambisa itonela namhlanje - Kufuneka senze isiseko sokulinganisa ukuze sibe nendawo yokukhangela ukuphucula umdlalo wethu. Ukwenza oku ndilindele inguqu yedijithali kwitonela yekhonkrithi etshiziweyo, usebenzisa amaqonga okufikelela kwidatha atsala imithombo yedatha esuka kwizixhobo zethu eziphantsi komhlaba, izityalo zebhetshi njl. ukuyifumana okokuqala” xa banokutshiza nokuba kwiprofayile efunekayo okanye ubukhulu. Ezi nkqubo ziya kuxhasa iinjineli ukuba zivavanye ukusetyenziswa kwezinto, ijoloji, kunye nomgangatho umzekelo. Ngokwenyani iwele ledijithali lexesha lokwenyani liya kuba nexabiso kakhulu kubo bonke abachaphazelekayo kwaye liya kuqhuba uphononongo lwemihla ngemihla lwekhabhoni kunye nokunciphisa iindleko, ngelixa lifumana iinkqubo ezilawulwayo, ezikhuselekileyo.

Iiplatifti zoqeqesho lwenyani yenyani yabaqhubi abaphambili ziyasekwa kwishishini lethu kunye neNormet's VR Sprayed Concrete Simulator, evunywe sisikimu sesiqinisekiso se-EFNARC C2 samazwe ngamazwe, ngumzekelo wamva nje ovumela abaqhubi bemibhobho ukuba baphucule izakhono zabo kwindawo yokufundela.
