Bio-mashoma simba mukusimudzira kwenyika yedu kusanzwisisa kupfuura kunzwisisa, mamwe matambudziko kupfuura kutsigirwa, asi nekuda kwerunako rwake rwekuzvarwa, uye pakupedzisira zuva nezuva kukura nekukura.
Pakupera kwegore ra2016, biomass yakagadzira makirogiramu mazana matatu nemazana mana nemazana mana emadhora emagetsi munyika yose, iri padyo nekubuditswa kwepagore kweChitatu Gorges Power Station, chiitiko chakakosha.
Zvakakosha, hafu yezvinhu zvaro zvakasvibirira zvinobva mukurima uye masango marara senge zvirimwa zvezviyo, uye imwe hafu yacho inobva mumarara emumaguta. Izvi zvinoreva kuti, painoburitsa yakachena magetsi magetsi, inogona kudzikamisa hosha huru mbiri dzezvakatipoteredza yekuvhurika kwemunda unopisa madzinde nemarara emumaguta, saka ine mabasa maviri ekudzivirira zvakatipoteredza.
Takaitawo zvakanaka mukuwedzera mari dzevarimi uye takanangana nekuderedza hurombo.
Sekureva kwedata reInternational Energy Organisation IEA data, kuumba kupisa kwemafuta mumusika wepasi rose webhizimusi rekusimudza simba rakaiswa pekutanga, asi mugove weChina ishoma kwazvo, kunwiwa kwegore rose muna2016 ingori mamirioni masere emamiriyoni, kana muna2013 mushure mekupararira kwehutsi hwenyika kutarisa nekuvandudza.
Grg haze inofanirwa kumanikidzwa marasha, kuoma kwekutsimbirira kwemarasha kunogara mukushandisa kwegore negore kwemamiriyoni mazana maviri nemakumi manomwe ematani eTe marasha anopfuura mazana zviuru mazana mashanu zvidiki uye zvepakati nepakati zvine marasha anopisa pasi pematani makumi maviri.
Iwo akapararira zvakanyanya, madiki vhoriyamu uye anonetsa kupisa zvakachena.
"Marasha kune gasi" akanaka, asi kwete echokwadi, kuumba kudziyisa mafuta pasina mubvunzo ndiyo yakanyanya kunaka sarudzo.
Izvo zvakarongerwa kusvika matani emamirioni makumi matatu mukati megumi nematanhatu-Yegore-mashanu Chirongwa nguva, nemamirioni zana ematani anokwanisika muna 2030.
Uye biomass simba rekugadzira, kuumba kupisa kwemafuta zvakare yakasimba biomass sezvinhu zvakagadzirwa, zvese mbishi zvinhu uye kugona kweaviri mabasa ekuchengetedza ezvakatipoteredza, pamwe nezvibatsiro zvekurima
Mumakore gumi ekutanga ezana ramakumi maviri nemasere, maGiogas nema biogas eGerman paakakura kubva pamazana anodarika mazana masere kusvika pamadhora zviuru zvishanu, achigadzira (apo) magetsi akawanda kupfuura hydro, China yakabviswa kubva kumabhaogas edzimba ekumaruwa kusvika makore mashoma apfuura.
Muzhizha ra2013, Muzvinafundo Cheng neni takanyora tsamba yakabatana kuna Premier Li Keqiang nezvekuvandudzwa kwegasi-gasi muChina.
'Anaerobic Fermentation ine simba rakawanda uye simba rekushandura zvinhu pakati pebyomass simba ekushandura nzira,' tsamba inoverenga.
Net greenhouse gasi inoburitsa yehupenyu hwakazara hupenyu (LCA) yefossil gasi yakasarudzika iri 398 gramu, nepo biogas inogadzirwa kubva kuzvipfuyo uye huku yehuku iri kubvisa 414 gramu.
Inofananidzwa nedhiziri uye peturu mota, mota bio-gasi inogona kudzikisa kuburitsa kwezvinhu zvine chinhu uye CO2 ne90%.
Uye zvakare, yangu huru isainzi yevhu. Mukuita kwe biomass kupisa patembiricha yakakwira, inodarika gumi mhando yezvirimwa zvinovaka muviri zvakaita se phosphorus, manganese, zinc nedare zvakasunganidzwa uye zvinokundikana kudzokororwa zvakare muvhu, nepo kuvhuvhuta kweanaerobic hakugone kudzokorodza ivhu chete, asi zvakare ive mune yakasikwa nyika.
Biogas ichangotanga muChina, asi tekinoroji yekutengesa nemidziyo zvave kukura.
National Energy Administration nebazi rezvekurima vakaita nhamburiko huru kusimudzira kugadzirwa kwemabhiriyoni masere m3 muChirongwa chegumi neshanu-chemakore mashanu, uye mari yekudyara inosvika 60% yeiyo biomass simba.
Anofungidzirwa kugona kugona muna 2030 anosvika makumi mana emamirioni m3, mabhiriyoni mashanu m3 kudarika fossil gasi rinounzwa kubva kuNorth Russian pombi.
Isu tinotonyanya kukurudzirwa nehurukuro yaMutungamiri Xi Jinping pamusangano wegumi nemana weCentral Leading Group for Financial and Economic Affairs pakupera kwa2016.
“Kukurudzira kudziyisa kwakachena munguva yechando mudunhu rekuchamhembe kwakakosha mukudziya kwevanhu munharaunda yekuchamhembe nekuderedza mazuva ehutsi. Ichi chikamu chakakosha chekisimusi mukugadzirwa kwesimba nekushandisa uye shanduko mumararamiro ehupenyu kumaruwa. ”
"Kumhanyisa kuraswa uye kushandiswazve kwemarara kubva kuzvipfuyo nekuhuku kwehuku kune chekuita nekugara pamwe nekugara kwevanopfuura mamirioni mazana matanhatu emamisha vagari, shanduko yesimba kumaruwa, uye nekukwanisa kuvandudza kubereka kwevhu uye kudzora kwekurima isiri-poindi kusvibiswa. Ichi chinhu chikuru chakanakira icho chinobatsira nyika uye nevanhu mukufamba kwenguva.
Isu tinofanirwa kutevedzera mutemo wekutsigirwa nehurumende uye mashandiro anotungamirwa nemakambani, titore biogas uye bio-gasi seyakanyanya nzira yekurapa, uye tishandise simba remuno nepedyo neiyo yekurima fetiraiza mumaruwa seyakanyanya kushandisa gwara, uye shingairira kupedza dambudziko rekurasa marara uye kushandisa zviwanikwa zvemapurazi makuru ekuchengeta huku munguva yeChirongwa chegumi nemashanu -Makore mashanu. ”
Zivai kuti mukutaura kwavo, Mutungamiri Xi akabatanidza kugadzirwa kwebiogas nekudzokororazve marara ehupenyu semombe uye huku yehuku, kudzora utsi uye kunetsekana nehupenyu hwevanhu.
Chekupedzisira, mvura biofuel, inova yekutanga yekutanga muChina, iyo yakareba kupfuura imwe mhando.
Pakutanga, kuchembera ethanol yezviyo yakatanga kune isiriyo kutanga, uye ndokuzoiswa pane cellulosic ethanol, iyo yaisakwanisa kurwiswa kwenguva yakareba.
Mumakore achangopfuura, nzira nyowani yakagadziriswa pasirese, kubva kuchikuva chikuva kusvika kune thermochemical chikuva uye budiriro dzakaitwa.
Izvo zvakasvibirira hazvisisiri starch nemafuta asi lignocellulose, uye chigadzirwa hachisisiri yakaderera mhando mafuta emafuta asi epamusoro giredhi biodiesel uye akareruka mafuta.
Tichifara, Wuhan Kaidi anga akamira pamusoro pehunyanzvi hwekumusoro uye munzvimbo inotungamira pasirese.
Chirimwa chebiodiesel chine goho repagore rematani mazana maviri ezviuru chichaiswa mukushanda muChina gore rinouya, rinove iro rinokosha zvikuru.
Tekinoroji budiriro inounza mbishi zvinhu budiriro, mbishi zvinhu budiriro inounza mbishi zvinhu mavambo budiriro.
Iyo feedstock yekugadzira biomass simba kugadzirwa, kuumba kupisa kwemafuta uye biogas kunouya zvakanyanya kubva kune yakasviba tsvina kubva muminda uye masango, nepo thermalization inogona kushandiswa kugadzira yakakwira-giredhi emafuta emafuta kubva kumahombekombe epasi ayo asingakwanise kurima zvirimwa asi anogona kukura akasimba simba mbesa.
Zvino, yakawanda sei iyi marginal land iripo?
Idata yatakawana kubva kubazi rezveminda uye zviwanikwa uye neState Forestry Administration muna2014 yaive mahekita emamiriyoni gumi nematanhatu.
Zvinonakidza kwazvo. Chaizvoizvo iri mamirioni mazana manomwe emamiriyoni anopfuura 1.8 bhiriyoni mu muvhu repurazi muChina. Icho chaicho chikuru biomass simba "goridhe mugodhi".
Yakawanda sei biomass inogona kugadzirwa kubva pa1.66 mahekita epasi pemarginal?
