Aikin Vesta
Project Vesta; kamfani ne na fa'ida na jama'a wanda ke bincike da aiwatar da saurin yanayi na ma'adinan olivine azaman dabarun rage yanayi don kama carbon acikin tekuna. Kamfanin yana fatan samun damar cire tan daya na carbon dioxide akan dalar Amurka 10 a babban sikeli. Kamfanin yana so ya yi amfani da olivine akan kashi 2% na shelves na nahiyar don sarrafa carbon, wanda suka kiyasta zai isa ya sake kwato duk hayakin carbon dioxide na shekara-shekara daga mutane. Har'ila yau, yana so ya sayar da kiredit na carbon.

Kamfanin yana gudanar da gwaje-gwaje, gwaje-gwajen toxicology, da kuma shirin gwaje-gwajen rairayin bakin teku.

Tarihi 
Project Vesta ya samo asali ne daga canjin yanayi da ke mai da hankali kan tunani Canjin yanayi. Kelly Erhart, wanda a baya ya kafa kamfanin bayan gida mara ruwa kuma ya koyi saurin yanayi daga rahoton yanayi, ya kafa Project Vesta a cikin 2019 a matsayin mai zaman kansa mai hedikwata a San Francisco. An gudanar da bincike a cikin gwaje-gwajen dakin gwaje-gwaje kan tsarin, amma ba a gudanar da gwaje-gwajen bakin teku ba kafin. Daga baya ƙungiyar ta canza daga ƙungiyar sa-kai zuwa kamfani mai amfanar jama'a.

Mai sarrafa biyan kuɗi Stripe ya riga ya biya tan 3,333 na ƙimar carbon sequestration daga kamfanin a $75 kowace ton.

Kamfanin ya ce a cikin 2022 zai iya cire carbon dioxide daga sararin samaniya a kan dala 35 ton idan aikin ya kai gigatonnes.

Acikin 2022, garin Southampton, New York, tare da haɗin gwiwar Jami'ar Stony Brook, da Cibiyar Haɗin gwiwar Jami'ar Cornell, da Project Vesta, sun fara aikin matukin jirgi don sanya yadudduka cubic 500 na olivine a kan rairayin bakin teku na Southampton wanda ke raguwa a matsayin matakan teku. tashi. A matsayin wani ɓangare na matukin jirgin da sauran gwaje-gwajen, kamfanin ya sa ido kan ko tsarin su yana fitar da tarin guba daga olivine.

Tsari 
Project Vesta yana gwada ko tsarin yanayin olivine zai rage koma bayan teku kuma ya rage yawan acidity na teku. Tsarin Vesta na aikin yana kwaikwayon tsarin yanayi na yanayi don canza olivine zuwa silicates da sauran sinadarai masu tsayayye, kamar calcium carbonate wanda ke hazo zuwa gindin teku yayin da rayuwar ruwa ke cinye sinadarai da ke faruwa ta zahiri kuma ya mutu (duba Carbon a cikin yanayin ruwa don ƙarin bayani). Ayyukan rairayin bakin teku masu a kan murkushe olivine yana ba da damar saurin yanayi fiye da sauran adibas na olivine, wanda kawai ke ɗaukar ƙarancin carbon dioxide.

Tun da yanayin yanayin olivine yana haifar da samfuran kwayoyin halitta irin su calcium carbonate wanda zai iya yin alkalinize ruwan teku na acidification ko sakin karafa irin su nickel mai bioavailable, kungiyar kuma ta yi bincike kan abubuwan sinadarai da toxicology na ruwan da abin ya shafa da rayuwar ruwa. Project Vesta yana buga binciken binciken su na kimiyya kuma har zuwa Mayu 2020 sun sanya hanyoyin su bude tushen.
