Kakaretso ea kutloisiso

Li-startups tsa carbon-to-value li etella pele ho ntlafatseng mesi ea khabone hore e be ntho ea bohlokoa. Mafura le thepa ea kaho li bontša ka ho hlaka monyetla o moholo oa phokotso ea carbon dioxide (CO2) le ho sebetsa 'marakeng. Ka lebaka leo, lihlahisoa tse ngata li etsoa ho sebelisoa CO2, ho tloha joala bo phahameng le mabenyane ho ea ho lintho tse sebetsang tse kang konkreite le lijo.

Boemo ba lisebelisoa tse thehiloeng ho CO2

Indasteri ea carbon tech ke 'maraka o ntseng o hōla ka potlako o' nileng oa hapa tlhokomelo ho tsoa ho bo-ramatsete. Tlaleho e entsoeng ke PitchBook e senotse hore lits'ebetso tsa theknoloji ea boemo ba leholimo tse sebetsanang le mahlale a phokotso ea khabone le mesi e phahamisitse lithuso tsa lichelete tsa $ 7.6 billion ho venture capital (VC) kotareng ea boraro ea 2023, ho feta rekoto e fetileng e behiloeng ka 2021 ka $ 1.8 bilione. Ho phaella moo, Canary Media e hlokometse hore halofo ea pele ea 2023, li-startups tse 633 tsa boemo ba leholimo li ile tsa phahamisa chelete, e leng keketseho ho tloha ho 586 ka nako e tšoanang selemong se fetileng.

Ho ipapisitsoe le tlhahlobo e entsoeng ka 2021 ke Univesithi ea Michigan's Global CO2 Initiative, lekala lena le na le monyetla oa ho fokotsa likhase tsa CO2 lefatšeng ka bophara ka liperesente tse 10. Nomoro ena e bolela hore tšebeliso ea khabone ke tlhokahalo e ke keng ea qojoa e lokelang ho kenyeletsoa letotong la mahlale a hlokahalang ho fihlela lipehelo tse felletseng tse behiloeng ke mebuso le likhoebo. 

Haholo-holo, mafura le lisebelisoa tsa mohaho, tse kang konkreite le li-aggregate, li na le maemo a phahameng ka ho fetisisa a ho fokotsa CO2 le bokhoni ba 'maraka. Ka mohlala, samente, karolo ea bohlokoa ea konkreite, e ikarabella bakeng sa karolo ea 7 lekholong ea likhase tsa CO2 lefatšeng ka bophara. Baenjiniere ba loanela ho fetola theknoloji ea konkreite ka ho etsa konkreite e kentsoeng ka CO2 e sa hapeng likhase tse futhumatsang lefatše empa hape e na le matla a maholo le ho tenyetseha ho feta balekane ba eona ba setso. 

Tšusumetso e senyang

Mefuta e fapaneng ea ho qala e lokolla lihlahisoa tse khahlisang tse entsoeng ka CO2. CarbonCure e thehiloeng Canada, e thehiloeng ka 2012, ke e 'ngoe ea mekhatlo ea pele ea ho kenyelletsa carbon ho thepa ea mohaho. Theknoloji e sebetsa ka ho kenya CO2 ka konkreite nakong ea ho kopanya. CO2 e kentsoeng e sebetsana le konkreite e metsi 'me e potlakela ho bolokoa joalo ka liminerale. Leano la khoebo la CarbonCure ke ho rekisa theknoloji ea eona ho bahlahisi ba thepa ea kaho. Feme e khutlisetsa litsamaiso tsa baetsi bana, e li fetola likhoebo tsa theknoloji ea carbon.

Air Company, e qalileng New York ho tloha 2017, e rekisa lintho tse thehiloeng ho CO2 tse kang vodka le litlolo tse nkhang hamonate. Feme e bile e hlahisitse sanitizer ea letsoho nakong ea seoa sa COVID-19. Theknoloji ea eona e sebelisa k'habone, metsi le matla a ka nchafatsoang, 'me e li kopanya ka har'a mochini ho etsa lino tse tahang joalo ka ethanol.

Ho sa le joalo, ho qala Twelve ho hlahisitse electrolyzer ea lebokose la tšepe e sebelisang metsi le matla a tsosolositsoeng feela. Lebokose le fetola CO2 hore e be khase ea synthesis (syngas), motsoako oa carbon monoxide le hydrogen. Sehlahisoa se le seng feela ke oksijene. Ka 2021, li-syngas li ile tsa sebelisoa ho jete ea pele ea lefatše ea carbon-neutral, e se nang mesaletsa ea lintho tsa khale. 

Qetellong, khoele ea pele le lesela le hlahisitsoeng ho tsoa ho khabone e hapiloeng li entsoe ka 2021 ke feme ea theknoloji ea baeloji ea LanzaTech ka kopanelo le lets'oao le phahameng la liaparo tsa liatleletiki la lululemon. Ho hlahisa ethanol ho tsoa mehloling ea litšila ea carbon, LanzaTech e sebelisa tharollo ea tlhaho. Feme e sebelisane le India Glycols Limited (IGL) le moetsi oa masela oa Taiwan Far Eastern New Century (FENC) ho etsa polyester ka ethanol ea eona. 

Litlamorao tsa lisebelisoa tse thehiloeng ho CO2

Litlamorao tse pharalletseng tsa lisebelisoa tse thehiloeng ho CO2 li ka kenyelletsa: 

• Mebuso e khothaletsang indasteri ea ho hapa khabone le liindasteri tsa boleng ba khabone ho phethahatsa boitlamo ba bona ba carbon net zero.
• Ho eketsa matsete a lipatlisiso mabapi le hore na carbon tech e ka sebelisoa joang liindastering tse ling, tse kang tlhokomelo ea bophelo bo botle le ho hlahloba sebaka.
• Lisebelisoa tse ling tsa carbon tech tse sebelisanang le lik'hamphani le lihlahisoa ho theha lihlahisoa tse thehiloeng ho carbon. 
• Brands e fetela ho lisebelisoa le lits'ebetso tse thehiloeng ho khabone ho ntlafatsa maemo a bona a tikoloho, sechaba, le puso (ESG).
• Bareki ba mekhoa e metle ba fetohela ho lihlahisoa tsa khabone tse nchafalitsoeng, ba fetolelang karolo ea 'maraka ho likhoebo tse tšoarellang.
• Thahasello e matlafalitsoeng ea k'hamphani ho thekenoloji ea carbon e lebisang ho thehoeng ha mafapha a khethehileng a tsepamisitseng maikutlo ho kopanyelletsang litheknoloji tsena mekhoeng e teng ea tlhahiso.
• Tlhokahalo e ntseng e eketseha ea litsebi tsa theknoloji ea carbon e susumetsang liunivesithi ho theha mananeo a thuto le mananeo a koetliso.
• Litšebelisano tsa machaba pakeng tsa mebuso ho tiisa melaoana ea carbon tech, ho ntlafatsa khoebo le ts'ebeliso ea lefats'e.

Lipotso tse lokelang ho nahanoa

• Mebuso e ka khothaletsa likhoebo joang hore li fetohele tšebetsong ea khabone ho isa boleng?
• Melemo e meng e ka bang teng ea ho sebelisa khabone hape ke efe?
