Icyumweru kimwe nyuma y’isohoka ry’ingamba za hydrogène ya guverinoma y’Ubwongereza, mu karere ka Liverpool hatangijwe igeragezwa ryo gukoresha hydrogène 100% mu gukora ibirahure bireremba, bikaba byari ku nshuro ya mbere ku isi.
Ibicanwa biva mu kirere nka gaze karemano bisanzwe bikoreshwa mugikorwa cyo kubyaza umusaruro bizasimburwa rwose na hydrogène, byerekana ko inganda zikirahure zishobora kugabanya cyane imyuka ihumanya ikirere kandi igatera intambwe nini yo kugera kuntego ya zeru.
Ikizamini cyakorewe mu ruganda rwa St Helens i Pilkington, isosiyete ikora ibirahuri yo mu Bwongereza, aho iyi sosiyete yatangiye gukora ibirahure bwa mbere mu 1826. Mu rwego rwo guca burundu Ubwongereza, inzego zose z’ubukungu zigomba guhinduka rwose.Inganda zingana na 25% by’ibyuka bihumanya ikirere mu Bwongereza, kandi kugabanya ibyo byuka ni ngombwa niba igihugu kigera kuri “net zero.”
Nyamara, inganda zikoresha ingufu ni imwe mu mbogamizi zikomeye zo guhangana nazo.Ibyuka bihumanya mu nganda, nko gukora ibirahure, biragoye cyane kugabanya ibyuka bihumanya binyuze muri ubu bushakashatsi, turi intambwe imwe yo gutsinda iyi nzitizi.Umushinga wibanze wa "HyNet Industrial Fuel Conversion" uyobowe ningufu ziterambere, kandi hydrogen itangwa na BOC, izaha HyNet ikizere cyo gusimbuza gaze naturel na hydrogène nkeya.
Ibi bifatwa nkibintu byambere ku isi byerekanwe kwinshi kwa hydrogène yaka 100% mu bidukikije bireremba (urupapuro).Ikizamini cya Pilkington mu Bwongereza ni umwe mu mishinga myinshi ikomeje gukorwa mu majyaruguru y'uburengerazuba bw'Ubwongereza kugira ngo hamenyekane uburyo hydrogen ishobora gusimbuza ibicanwa biva mu nganda.Nyuma yuyu mwaka, ibindi bigeragezo bya HyNet bizabera muri Port Sunlight, Unilever.
Iyi mishinga yo kwerekana izashyigikira hamwe guhindura ibirahuri, ibiryo, ibinyobwa, ingufu n’imyanda ikoreshwa na hydrogène nkeya ya karubone kugirango isimbuze ikoreshwa ry’ibicanwa.Ibigeragezo byombi byakoresheje hydrogen yatanzwe na BOC.Muri Gashyantare 2020, BEIS yatanze miliyoni 5.3 z'amapound yo gutera inkunga umushinga wa HyNet wo mu nganda uhindura ibicuruzwa binyuze mu mushinga wo guhanga ingufu.
Ati: “HyNet izazana akazi no kuzamuka mu bukungu mu majyaruguru y'uburengerazuba no gutangiza ubukungu buke bwa karubone.Twibanze ku kugabanya ibyuka bihumanya ikirere, kurinda imirimo 340.000 isanzwe ikora mu karere k’amajyaruguru yuburengerazuba, no guhanga imirimo mishya irenga 6.000., Gushyira akarere mu nzira yo kuba umuyobozi w'isi mu guhanga ingufu zisukuye. ”
Matt Buckley, umuyobozi mukuru w’Ubwongereza wa Pilkington UK Ltd, ishami rya NSG Group, yagize ati: “Pilkington na St Helens bongeye guhagarara ku isonga mu guhanga udushya mu nganda kandi bakora ikizamini cya mbere cya hydrogène ku isi ku murongo w’ibirahure bireremba hejuru.”
“HyNet izaba intambwe ikomeye yo gushyigikira ibikorwa byacu bya decarbonisation.Nyuma yibyumweru byinshi byikigereranyo cyuzuye cyibicuruzwa, byagaragaye neza ko bishoboka gukora uruganda rwikirahure kireremba hamwe na hydrogène neza kandi neza.Ubu turategereje igitekerezo cya HyNet kizaba impamo. ”
Ubu, abakora ibirahuri byinshi kandi biyongera R&D no guhanga udushya twogukoresha ingufu no kugabanya ibyuka bihumanya ikirere, kandi bagakoresha ikoranabuhanga rishya ryo gushonga kugirango bagenzure ingufu zikoreshwa mubirahure.Muhinduzi azagutondekanya bitatu kuri wewe.
1. Tekinoroji yo gutwika Oxygene
Oxygene yaka bivuga inzira yo gusimbuza umwuka na ogisijeni mugikorwa cyo gutwika lisansi.Iri koranabuhanga rituma hafi 79% ya azote mu kirere itakigira uruhare mu gutwika, bishobora kongera ubushyuhe bwa flame kandi byihutisha umuriro.Byongeye kandi, imyuka ihumanya ikirere mugihe cyo gutwika oxy-lisansi igera kuri 25% kugeza kuri 27% yo gutwika ikirere, kandi igipimo cyo gushonga nacyo cyateye imbere cyane, kigera kuri 86% kugeza 90%, bivuze ko ubuso bw itanura busabwa kugirango ubone ibirahuri bingana biragabanuka.Ntoya.
Muri Kamena 2021, nk'umushinga w'ingenzi wo gutera inkunga inganda mu Ntara ya Sichuan, Ikoranabuhanga rya elegitoroniki rya Sichuan Kangyu ryatangiye kurangiza ku mugaragaro umushinga mukuru w'itanura ryayo rya ogisijeni yose, rikaba rifite ahanini uburyo bwo guhindura umuriro no kuzamura ubushyuhe.Umushinga wubwubatsi ni "ultra-thin electronic cover cover substrate, ITO conductive glass substrate", kuri ubu ikaba ari nini nini imwe-itanura imwe-imirongo ibiri-yose ya ogisijeni yaka ireremba umurongo wa elegitoroniki ikora mubushinwa.
Ishami ryo gushonga ryumushinga rikoresha oxy-lisansi yaka + tekinoroji yo kongera amashanyarazi, ishingiye kuri ogisijeni na gaze gasanzwe, hamwe no gushonga bifasha binyuze mu kongera amashanyarazi, nibindi, bidashobora kuzigama 15% kugeza kuri 25% gusa yo gukoresha lisansi, ariko kandi ongera itanura Ibisohoka kuri buri gice cy itanura byongera umusaruro hafi 25%.Byongeye kandi, irashobora kandi kugabanya ibyuka bihumanya ikirere, kugabanya igipimo cya NOx, CO₂ nizindi aside ya azote ikomoka ku gutwikwa hejuru ya 60%, kandi igakemura byimazeyo ikibazo cy’amasoko yangiza!
2. Ikoreshwa rya tekinoroji ya gaz
Ihame rya tekinoroji ya gazi ya flue nugukoresha okiside kugirango okiside NOX kugeza NO2, hanyuma NO2 yabyaye ikururwa namazi cyangwa igisubizo cya alkaline kugirango igere kuri denitration.Ikoranabuhanga rigabanijwe cyane cyane kugabanya catalitike yo kugabanya (SCR), guhitamo kugabanya kugabanuka kwa catalitiki (SCNR) no gutandukanya gazi ya flue.
Kugeza ubu, mu bijyanye no gutunganya imyanda, amasosiyete y’ibirahure mu gace ka Shahe yubatse ahanini ibikoresho byo kwamagana SCR, akoresheje ammonia, CO cyangwa hydrocarbone mu rwego rwo kugabanya imiti igabanya OYA muri gaze ya flux kuri N2 ahari ogisijeni.
Hebei Shahe Umutekano Inganda Co, Ltd.Kuva ryuzura kandi rigashyirwa mu bikorwa muri Gicurasi 2017, gahunda yo kurengera ibidukikije yakoraga neza, kandi ubwinshi bw’imyuka ihumanya muri gaze ya flue irashobora kugera ku bice bitarenze mg / N㎡, dioxyde de sulfure iri munsi ya mg / N 50 And, na okiside ya azote iri munsi ya 100 mg / N㎡, kandi ibipimo byangiza umwanda bigera ku gipimo gihamye igihe kirekire.
3. Gupfusha ubusa ingufu z'amashanyarazi
Ikirahure cyo gushonga itanura imyanda itanga ingufu ni tekinoroji ikoresha ibyuka bishyushya imyanda kugirango igarure ingufu zumuriro ziva mumashyanyarazi yimyanda yibirahure kugirango itange amashanyarazi.Amazi yo kugaburira amazi ashyushye kugirango atange amavuta ashyushye, hanyuma amavuta ashyushye yoherejwe kuri turbine kugirango yongere kandi akore imirimo, ahindure ingufu z'amashanyarazi ingufu za mashini, hanyuma atware generator kubyara amashanyarazi.Iri koranabuhanga ntirizigama ingufu gusa, ahubwo rifasha no kurengera ibidukikije.
Xianning CSG yashoye miliyoni 23 Yuan mu iyubakwa ry’umushinga w’amashanyarazi y’imyanda mu 2013, kandi wahujwe neza na gride muri Kanama 2014. Mu myaka yashize, Xianning CSG yakoresheje ikoranabuhanga ry’amashanyarazi y’imyanda kugira ngo igere ku kuzigama ingufu kandi kugabanya ibyuka bihumanya mu nganda zikirahure.Biravugwa ko impuzandengo y’amashanyarazi ya Xianning CSG y’amashanyarazi y’amashanyarazi agera kuri miliyoni 40 kWh.Impinduka ihindurwa ibarwa hashingiwe ku gukoresha amakara asanzwe y’amashanyarazi angana na 0.350kg y’amakara asanzwe / kWt hamwe na karuboni ya dioxyde de carbone ya 2.62kg / kg y’amakara asanzwe.Amashanyarazi ahwanye no kuzigama 14.000.Toni yamakara asanzwe, igabanya imyuka ya toni 36,700 ya dioxyde de carbone!
Intego ya "carbone peak" na "kutabogama kwa karubone" ni inzira ndende.Isosiyete ikora ibirahure iracyakeneye gukomeza imbaraga zayo mu kuzamura ikoranabuhanga rishya mu nganda z’ibirahure, guhindura imiterere ya tekiniki, no guteza imbere ishyirwa mu bikorwa ryihuse ry’intego z’igihugu cyanjye “karuboni ebyiri”.Nizera ko mu iterambere rya siyanse n’ikoranabuhanga no guhinga byimbitse by’abakora ibirahure byinshi, inganda z’ibirahure rwose zizagera ku iterambere ryiza, iterambere ry’icyatsi n’iterambere rirambye!
