Kodi Biomass Ndi Mphamvu Zotani?

Mphamvu ya biomass ndi yakale ngati moto wa caveman, ndipo imakhalabe magwero ofunika mphamvu zowonjezereka padziko lonse lapansi. Ngakhale kuti ntchito yake yakale inali yotentha ndi mphamvu, komabe anthu ambiri sadziŵa kuti biomass mphamvu imatanthauzanji kwenikweni, kapena kuti zimakhala zotani.

Kodi Biomass Ndi Mphamvu Zotani?

Mphamvu za biomass ndi mtundu uliwonse wa mphamvu zomwe zimagwiritsa ntchito zamoyo (chomera kapena nyama) monga gwero lake.

Chifukwa tanthauzo la biomass ndi lalikulu kwambiri, mafuta omwe angatengedwe kuti "zinyama" zimaphatikizapo zinthu zosiyanasiyana ndipo ochita kafukufuku akupeza zatsopano zowonjezera mphamvu zamagetsi nthawi zonse.

Manyowa a zinyama, zinyalala zakuda, nkhuni zamtengo wapatali, mafuta a masamba, algae, mbewu monga chimanga, shuga, switchgrass ndi zina zamasamba - ngakhale pepala ndi zinyalala zapanyumba - zingagwiritsidwe ntchito ngati gasi lamoto.

Mafuta a biomass akhoza kutembenuzidwa mwachindunji kutentha kwa mphamvu kudzera mu kuyaka, monga kutentha kwa chipika pamoto. Nthaŵi zina, chilengedwe chimasandulika mafuta ena; Zitsanzo zimaphatikizapo mafuta a ethanol opangidwa kuchokera ku chimanga kapena gesi ya methane yomwe imachokera ku zinyalala za nyama.

Kodi Magetsi Ambiri Amathandiza Bwanji?

Pafupifupi mphamvu zitatu kapena zinayi za mphamvu za ku America zimachokera ku zinyama, pamene 84 peresenti imachokera ku mafuta monga mafuta, malasha, ndi mafuta. Mwachiwonekere, zamoyo zam'madzi zimakhala ndi njira yochuluka zisanayambe zisanavomerezedwe ngati gwero la mphamvu.

Ngakhale kuti pali mavutowa, pali ubwino wambiri kuti ntchito yowonjezereka ikugwiritsidwe ntchito. Chinthu chimodzi chodziwika bwino kuti mafuta oyambitsa zitsamba ali ndi mphamvu zina zowonjezera mphamvu ndi kuti zitsamba zimakhala zowonjezereka: Titha kukula zomera zambiri, koma palibe amene angathe kupanga mafuta ambiri.

Ubwino winanso ndi wakuti magwero ena a zinyama, monga manyowa, utuchi, ndi zinyalala, amagwiritsira ntchito mafuta omwe angawonongeke. Choncho, magwerowa amachepetsa kudalira kwathu pa mafuta ndi mphamvu za nyukiliya komanso kuchepetsa mavuto omwe amachititsa - phokoso, fungo, nyongolotsi, kuchepa kwa chuma - zomwe zimagwirizanitsidwa ndi zinyumba.

Biomass Energy ndi Mazingira

Biomass ndi gwero la mphamvu zowonjezereka zomwe zingathe kubwereranso pamtundu uliwonse wa mbewu, zokolola nkhuni kapena mulu wa manyowa - koma sizingwiro. Chifukwa chakuti amachokera ku magwero osiyanasiyana, mafuta a biomass nthawi zonse sagwirizana ndi kapangidwe ka mphamvu kapenanso mphamvu, ndipo pakali pano palibe makina opangira zitsulo komanso otsatsa monga momwe ziliri ndi mafuta ndi gasi.

Kuonjezerapo, kutentha kwa mafuta a zamoyo, monga kutentha kwa mafuta, kumapangitsa kuti zinthu zowonongeka zowonongeka, monga mankhwala , carbon dioxide (CO) ndi carbon dioxide (CO2) zikhale zoopsa. CO2 ndi mpweya wowonjezera kutentha womwe ndi chimodzi mwa zifukwa zomwe zimayambitsa kutentha kwa dziko ndi kusintha kwa nyengo.

Mphamvu yowonjezereka ya mphamvu zamagetsi, komabe, ikhoza kuchepetsa kwambiri chilengedwechi. Pamene kutentha kwa biomas kutulutsa carbon monoxide ndi CO2 m'mlengalenga, mitengo, ndi zomera zomwe zimakula monga mphamvu zowonongeka zimatulutsa mpweya wochokera m'mlengalenga panthawi ya photosynthesis. Njira imeneyi imatchedwa "kutsekemera kaboni" kapena "kubanki".

Kodi Biomass Energy Eco-Friendly?

Pali kutsutsana kwakukulu kwa mphamvu yowonjezera mphamvu ya biomass ndi sequtering carbon.

Akatswiri ena apeza kuti mpweya wa carbon (CO ndi CO2) umatulutsidwa pamene mafuta amtundu wotentha amawotchedwa ndi ofanana ndi kaboni yosungidwa m'mitengo ndi zomera zomwe zimakula pamtunda "m'minda." Kufufuza kumeneku kumapangitsa kuti mphamvu zamagetsi zisawonongeke komanso zisawonongeke.

Komabe, akatswiri ena adapeza kuti chitukuko chazamagetsi chomwe chimapangitsa kuti chilengedwe chikhale chonchi chimasokoneza chilengedwe komanso khalidwe la mpweya. Greenpeace yatulutsa lipoti lakuti, "Kutentha Biomess," yomwe imapeza kukula kwakukulu kwa mphamvu zowonongeka kwapangitsa kuti pakhale zowonongeka monga utuchi ndi mapeyala a mapepala, ndipo mitengo yonse ndi malo ena ofunika kwambiri a nkhalango tsopano akuwonongedwa:

"Canada yekha imatulutsa ma gatgatoni 40 a mpweya wa CO2 chaka chilichonse kuchokera ku bioenergy production, ndalama zomwe zimadutsa mpweya wamoto wa 2009 ku Canada.

CO2 imachokera idzavulaza nyengo kwa zaka makumi ambiri isanatengedwe ndi mitengo yatsopano. "

Tsogolo la Biomass Energy

Ngakhale kuti ndi gwero lakale la mphamvu, mphamvu zowonongeka zamoyo zili ndi njira yochuluka zogwiritsira ntchito zisanayambe kugwiritsira ntchito mphamvu zina monga magetsi ndi nyukiliya .

Komabe, malo amoto sakuyendamo, ndipo ndondomeko yamphamvu yowonjezera ingakhale njira yabwino kwambiri yothetsera chitetezo cha mphamvu m'zaka za m'ma 2000. Monga momwe ofufuza a ku Oak Ridge National Laboratory adanenera, "Kafukufuku amasonyeza kuti njira yabwino [biomass] idzakhala yosiyana ndi malo ndi malo, otsimikiziridwa ndi ubwino wa dzikolo, ntchito zake zamakono, kugwiritsa ntchito mpikisano, ndi zofuna za mphamvu."

Dziwani zambiri zokhudza magetsi a zinyama powerenga nkhani izi pazitsamba zamatabwa, zowonongeka, zamagetsi, biogaz ndi zinyama zamadzi.
