Kusiyana nemamwe magetsi anovandudzwazve, kuvandudzwa kwebiomass magetsi ekugadzira tekinoroji kunongokanganisa mabhenefiti ehupfumi, kwete

nzanga.Panguva imwecheteyo, kugadzirwa kwemagetsi ebiomass kunodawo kusakuvadza uye kuderedzwa kurapwa kwemarara ekurima nemasango nedzimba

marara.Rubatsiro rwayo rwezvakatipoteredza uye munzanga yakakura zvikuru kupfuura simba rayo rinobatsira.Kunyangwe mabhenefiti akaunzwa nekuvandudzwa kwebiomass

tekinoroji yekugadzira magetsi yakakosha kusimbisa, mamwe matambudziko akakosha ehunyanzvi mune biomass magetsi ekugadzira mabasa haagone kushanda zvakanaka

yakagadziriswa nekuda kwezvinhu zvakaita senzira dzisina kukwana dzekuyera uye zviyero zvebiomass zvakabatanidzwa kugadzirwa kwemagetsi, iyo isina simba nyika yemari.

rubatsiro, uye kushomeka kwekuvandudza matekinoroji matsva, zvinova zvikonzero zvekudzikamisa kugadzirwa kwemagetsi ebiomass.

tekinoroji, Naizvozvo, matanho anonzwisisika anofanira kutorwa kuti akusimudzire.

(1) Kunyangwe kusuma tekinoroji uye kusimudzira kwakazvimiririra ari ese ari madhairekitori makuru ekuvandudza simba remumba biomass

indasitiri yechizvarwa, isu tinofanirwa kuziva zvakajeka kuti kana tichida kuve ne nzira yekupedzisira, isu tinofanirwa kuyedza kutora nzira yekusimudzira yakazvimirira,

uyezve gara uchivandudza matekinoroji epamba.Panguva ino, inonyanya kuvandudza nekuvandudza biomass magetsi ekugadzira tekinoroji, uye

mamwe matekinoroji ane hupfumi huri nani anogona kushandiswa mukutengesa;Nekuvandudzwa zvishoma nezvishoma uye kukura kwebiomass sesimba guru uye

biomass magetsi ekugadzira tekinoroji, biomass ichave nemamiriro ekukwikwidza nemafuta emafuta.

(2) Mutengo wekutonga munharaunda unogona kudzikiswa nekudzikisira huwandu hwezvikamu zvemagetsi zvinopisa tsvina yekurima uye

nhamba yemakambani ekugadzira magetsi, uku ichisimbisa manejimendi ekutarisa mapurojekiti ekugadzira magetsi ebiomass.Panyaya yemafuta

kutenga, kuve nechokwadi chekupa yakakwana uye yemhando yepamusoro yezvigadzirwa, uye kuisa hwaro hwekushanda kwakagadzikana uye kwakanaka kwesimba remagetsi.

(3) Kuwedzera kunatsiridza yakasarudzika mutero marongero ekugadzirwa kwemagetsi ebiomass, kuvandudza mashandiro ehurongwa nekuvimba nekubatana.

kushandura, kukurudzira uye kutsigira kuvakwa kwemapurojekiti ekuratidzira, uye kudzikisira kukosha

yemapurojekiti ebiomass anongoburitsa magetsi asi kwete kupisa.

(4) BECCS (Biomass simba rakasanganiswa nekabhoni kubatwa uye kuchengetedza tekinoroji) yakurudzira modhi inosanganisa biomass simba rekushandisa.

uye kubatwa nekuchengetedza kabhoni dhaibhorosi, zvine zvakanakira kaviri kabhoni emissions uye kabhoni isina kwayakarerekera simba.BECCS inguva refu

tekinoroji yekudzikisa emission.Parizvino, China ine tsvakiridzo shoma mundima iyi.Senyika yakakura yekushandisa zviwanikwa uye kabhoni emissions,

China inofanirwa kusanganisira BECCS muhurongwa hwekutarisana nekushanduka kwemamiriro ekunze uye kuwedzera matura ayo ehunyanzvi munzvimbo ino.
