Mtsutso waukulu wa biofuels ndi carbon dioxide

biofuel

Masiku ano biofuels amagwiritsidwa ntchito pazinthu zina zachuma. Ogwiritsidwa ntchito kwambiri ndi Mowa ndi biodiesel. Zimamveka kuti mpweya wa kaboni dayokisaidi wotulutsidwa ndi biofuel umakhala wolingana ndi kuyamwa kwa CO2 komwe kumachitika ndi photosynthesis mu zomera.

Koma zikuwoneka kuti izi sizomwe zili choncho. Malinga ndi kafukufuku wa University of Michigan Energy Institute motsogozedwa ndi John DeCicco, kuchuluka kwa kutentha komwe CO2 imatulutsa potulutsa biofuels sikugwirizana ndi kuchuluka kwa CO2 kotengeka ndi zomera panthawi ya photosynthesis pamene mbewu zimakula.

Kafukufukuyu adachitidwa kutengera ndi zomwe adalemba Dipatimenti ya Zaulimi ku United States. Nthawi zinawunikiridwa momwe kupanga biofuel kudakulirakulira ndipo kuyamwa kwa mpweya woipa wochokera ku mbewu kumangolepheretsa 37% ya mpweya wonse wa CO2 wotulutsidwa powotcha biofuels.

Zotsatira zamaphunziro aku Michigan zimatsimikizira kuti Kugwiritsa ntchito biofuel kukupitilizabe kukulitsa kuchuluka kwa CO2 yotulutsidwa m'mlengalenga ndipo sizinachepe monga momwe timaganizira kale. Ngakhale gwero la mpweya wa CO2 limachokera ku biofuel monga ethanol kapena biodiesel, mpweya wotulutsa mlengalenga ndiochulukirapo kuposa womwe umadzala ndi mbeu za mbeu, chifukwa chake akupitilizabe kukulitsa kutentha kwanyengo.

A John DeCicco adati:

'Aka ndi kafukufuku woyamba kuwunika bwino mpweya womwe umatulutsidwa pamtunda pomwe biofuels amalimidwa, m'malo mongoganiza za izi. Mukayang'ana zomwe zikuchitika padziko lapansi, mudzapeza mpweya wokwanira amene amachotsedwa mumlengalenga kuti athe kulinganiza zomwe zimatuluka mchipilala. "
