Leha ho na le kemiso e tšosang ea nako e behiloeng ke Tumellano ea Paris, lithanele tsa zero-carbon li ka fihlelleha haeba litharollo tse nepahetseng li ka kengoa tšebetsong.

Indasteri ea lithanele e boemong bo holimo moo botsitso le decarbonisation li leng kaholimo ho li-ajenda tsa batsamaisi. Ho fihlela sepheo sa phetoho ea maemo a leholimo ea 1.5°c ka 2050, indasteri ea likotopo e tla hloka ho fokotsa likhase tsa CO2 ka kotloloho ho ea ho zero.

Hona joale ke linaha tse fokolang haholo le merero ea mekhoa ea motheo e "tsamaeang puo" le ho nka bohato ba ho fokotsa carbon. Mohlomong Norway ke naha e le 'ngoe e etellang pele,' me, joalo ka 'maraka oa bona oa likoloi tsa motlakase oa malapeng, thepa ea kaho ea motlakase e ntse e sebelisoa ka ho eketsehileng,' me metse e meholo e tla ba le kaho ea carbon neutral ka 2025. Ka ntle ho Norway, linaha tse seng kae le merero ea Europe ka mohlala. , ba theha bonyane lipheo tsa litabatabelo tsa ho fokotsa khabone, empa hangata ba tsepamisitse maikutlo feela ho nts'etsopele metsoako ea konkreite ea khabone e tlase.

Indasteri ea lithanele e kenya letsoho ho khase ea CO2 lefatšeng ka bophara 'me e na le karolo eo e lokelang ho e bapala phokotsong ea khabone. Indasteri e tobane le khatello e ntseng e eketseha ho tsoa ho baetsi ba maano, batseteli le bareki ho ts'ebetso ea decarbonise.


Hang ha ho nkuoe qeto ea ho haha ​​kotopo e ncha, moralo o bohlale o lateloang ke kaho e hloahloa e shebaneng le k'habone qetellong e tla lebisa litšenyehelong tse tlase tsa projeke.

Leha ba bang ba lumela hore ho fokotsa khabone ho lekana le litšenyehelo tse phahameng tsa projeke, ts'ebetso e ntle ea taolo ea khabone indastering ea kaho e fana ka maikutlo a fapaneng, 'me ka mokhoa o akaretsang oa bophelo bohle ba projeke, ka lienjineri tse tsepamisitseng maikutlo ho bolokeng khabone, sena se fana ka ts'ebetso ea ho boloka litšenyehelo tsa projeke ka kakaretso. hape! Ka sebele ona ke molao-motheo o ka morao ho PAS2080 e tloaelehileng ho Taolo ea Carbon in Infrastructure 'me ho loketse ho sebelisoa mererong bakeng sa ba chesehelang decarbonisation.

Ka lebaka la tabatabelo ena e ntseng e hola le tlhokeho ea decarbonisation, lisente tsa ka tse hlano ke tsena: lintlha tse tharo tsa bohlokoa tse ka potlakisang boiteko ba ho tlosa carbonate le ho hatela pele haholo ho fihlela sepheo sa phetoho ea tlelaemete ea 1.5°C - Ho aha ka bohlale, ho aha ka bokhabane, le ho aha bophelong.

Haha ka bohlale - Tsohle li qala ka moralo o mocha le o nahanelang

Melemo e kholo ea decarbonisation ka har'a lithanele e tsoa liqetong tsa methati ea ho rala le ea meralo. Likhetho tse tlang pele bakeng sa merero e ka bang teng li bohlokoa pale ea khabone, ho kenyelletsa le ho haha ​​ho hang, kapa ho batla ho ntlafatsa kapa ho lelefatsa bophelo ba thepa e teng pele ho latela mokhoa o mocha oa ho aha.

Kahoo, ke qalong ea mokhahlelo oa ho etsa liphapang tse ka sehloohong, 'me lithaneleng ke moralo moo karolo e kholo ka ho fetisisa ea ho boloka carbon e ka etsoang. Melemo e joalo ea meralo e ka kengoa tšebetsong habonolo mererong ea lithanele ka boetapele ba bareki, mohlala ho khothaletsa mekhoa ea ho reka e hohelang borakonteraka ba ka sehloohong ho fana ka lits'ebetso le lisebelisoa tse ncha tsa ho fokotsa khabone, tse hlasimollang ketane e pharalletseng ea phepelo ea thepa.

Lithakong tsa sefahleho tse bulehileng, tšehetso ea lejoe la konkreite e fafalitsoeng e sebelisoa lefatšeng ka bophara, 'me linaheng tse ngata lefats'eng, ka lebaka la boleng ba eona bo phahameng, e boetse e amohetsoe ka bophara bakeng sa lithapo tsa kotopo tse sa feleng, tse bolokang lipakeng tsa 20-25% ea konkreite e sebelisoang kotopong e tloaelehileng. litsamaiso tsa lera. Ke lumela hore lits'ebetso tsa sejoale-joale tse fafalitsoeng tsa konkreite kajeno, tse kopanyang maemo a holimo a Portland Cement replacement, polymer fibers le mahlale a macha a thibelang metsi, li fana ka menyetla ea ho fihlela phokotso e fetang 50% ea khabone ka har'a lithanele tsa rona. Empa hape, litharollo tsena tsa 'Haha Bohlale' li tlameha ho nkuoa le ho kengoa ts'ebetsong qalong ea moralo ho eketsa bokhoni bo boholo ba ho boloka khabone. Tsena ke litharollo tsa 'nete tsa ho boloka chelete ea' nete, 'me re ka etsa mehato ena e meholo kajeno ka moetlo o nepahetseng oa sehlopha, moralo o nepahetseng, hammoho le mefuta e mecha e thabisang ea ho reka thepa e qobellang lintho tse ntle hore li etsahale.

Joalo ka lehlakore chete, phephetso bakeng sa k'habone e fafalitsoeng ka konkreite e tlase ke ho eketseha butle ha matla lihora tse 'maloa tsa pele ka mor'a ho fafatsa. Ho fumana matla pele ho nako ho bohlokoa bakeng sa polokeho e holimo le tlhahiso ea ho haha ​​​​marako a lekaneng. Lithuto tse khahlisang tseo re li entseng ka li-geopolymers (metsoako e se nang samente ea Portland) li bonts'itse hore re ka fumana konkreite ea khabone e tlase haholo ka matla a pele a matla, leha re ntse re tsoela pele ho ntlafatsa ts'ebetso e hlokahalang ea nako e telele ho etsa hore metsoako ena e sebetse haholoanyane.


Mohato o latelang oo re ka o nkang mabapi le lithanele tsa carbon zero ke ho sebetsa hantle haholo ts'ebetsong eohle ea kaho.


Tsepamiso ea pele - likamano tsa maano mabapi le moralo le ts'ebelisano 'moho le borakonteraka le ketane ea phepelo.

Lisebelisoa tsa konkreite tse fafalitsoeng tse tlase le tse tlase haholo. Li-accelerator tse ncha le li-membrane ke tsa bohlokoa.

Koetliso ea simulator, tumello ea EFNARC, ntlafatso e tsoelang pele, nts'etsopele ea ho fafatsa ka thuso ea komporo.

Batho ke senotlolo sa ho etsa mosebetsi o tlase oa carbon SCL. E ke ke ea tsoa molaong oa mmuso. Basebelisi ba merero ba tlameha ho etella pele.

Mokhoa o akaretsang oa moralo le kaho oa kotopo oa hlokahala ho fokotsa indasteri. Mohato o mong le o mong oa ts'ebetso o fana ka karolo ea bohlokoa ea ho boloka khabone.

Haha ka bokhabane - Thepa e bohlale, batho le digitalisation

Ho tla hlokahala boiteko bo bongata ho sebetsana le mehloli ea mantlha ea mesi le ho felisa carbonise. Liketso tse joalo li kenyelletsa khato ea ho fumana mokhoa o tsitsitseng, tšebeliso e khethehileng ea mafura, likoloi tsa motlakase, hammoho le ho fetohela ho bafani ba motlakase o motala ho matlafatsa merero ea rona ea kaho ea lithanele.

Mohlala oa nyehelo ea rona e tšoarellang ke likoloi tsa rona tsa betri tsa SmartDrive tsa motlakase. SmartDrive e fana ka ts'ebetso e ntlafetseng ka mesi e se nang letho ea lehae. Li boetse li felisa litšenyehelo tsa ho tsamaisa mafura le mafura 'me li na le litšenyehelo tse tlase tsa tlhokomelo ea lisebelisoa. Ka mohlala, likonteraka tsa kotopo tsa Norway li se li ntse li sebetsa ho fihlela lipheo tsa 2050 tsa carbon net zero ka ho sebelisa liroboto tse fafatsang tsa SmartDrive Spraymec 8100 SD tse lefisoang li sebelisa motlakase oa marang-rang a fehloang ka metsi.

Sena ke nete ea zero mme 2050 e lokile.

Taba ea bohlokoa phokotsong ea khabone ke ho qala ho metha le ho theha ts'ebeliso ea rona ea khabone mererong ea ho tsamaisa lithanele kajeno - Re hloka ho theha motheo oo re lokelang ho lekanya ho ona e le hore re be le ntlha ea ho ntlafatsa papali ea rona. Ho etsa sena ke lebelletse phetohelo ea dijithale ho kotopo ea konkreite e fafalitsoeng, ho sebelisa sethala sa phihlello ea data se hulang mehloli ea data ho tsoa lisebelisoa tsa rona tse ka tlas'a lefatše, limela tsa batch joalo-joalo, empa hape le lisebelisoa tse bohlale le tsa nako ea 'nete tsa 3D sefahlehong sa ho epolloa se tšehetsang basebelisi ba liroboto " ho e fumana ka lekhetlo la pele” ha ba khona ho fafatsa ka boemo bo hlokahalang kapa botenya. Litsamaiso tsena li tla ts'ehetsa baenjiniere ho lekola ts'ebeliso ea thepa, jeoloji le boleng mohlala. Ha e le hantle lefahla la sebele la dijithale e tla ba la bohlokoa haholo ho bohle ba amehang 'me le tla tsamaisa tlhahlobo ea letsatsi le letsatsi ea khabone le phokotso ea litšenyehelo, ha e ntse e fihlella lits'ebetso tse laoloang, tse bolokehileng.

Haha bophelo bohle

Rona nre tlameha ho se be sechaba se lahlang lintho, haholo-holo bophelong ba rona ba ho lahla lintho! Thepa ea Normet e tla tšoarella, 'me kae kapa kae moo re ka khonang re ka sebelisa lisebelisoa le lisebelisoa hape ho haha ​​​​lisebelisoa tse ncha le thepa e ncha ea kaho.

Ka bokhuts'oane, ho hlokahala boiteko bo bongata mekhoeng e fapaneng ho potlakisa boiteko ba ho tlosa carbonate. Ha se feela ka konkreite e tlase ea carbon. Kaofela re na le mosebetsi oo re lokelang ho o etsa, kahoo ha re fihleng ho oona 'me re be le lithanele tse "tlase tsa carb".
