LNG ingachepetse kwambiri mpweya wa SOx ndi tinthu tating'onoting'ono, komanso mpweya wa NOx, poyerekeza ndi dizilo. Komabe, LNG ikadali mafuta opangidwa kale, ndipo nkhani ya "methane slip" (kutuluka kwa methane) ingachepetse ubwino wake wa nyengo, chifukwa methane ndi mpweya wamphamvu kwambiri wowonjezera kutentha. LNG nthawi zambiri imawonedwa ngati mafuta osinthira.
2. Biofuel (Biodiesel, HVO, ndi mitundu ina)
Mafuta a biofuel ali ndi kuthekera kochepetsa mpweya woipa ngati apezeka m'malo osungira zinthu. Ubwino wawo ndi wakuti angagwiritsidwe ntchito m'mainjini omwe alipo omwe ali ndi kusintha kochepa, zomwe zimapangitsa kuti akhale oyenera kukonzedwanso m'sitima. Mavuto ndi monga kupezeka kwa zinthu, khalidwe lokhazikika, komanso kuonetsetsa kuti zipangizo zopangira sizikupikisana ndi zosowa za chakudya kapena kuwononga nkhalango.
3. Methanol (kuphatikiza e-methanol)
Methanol ikuyamba kugwira ntchito chifukwa ndi yosavuta kuigwiritsa ntchito kuposa hydrogen ndipo imatha kupangidwa "yobiriwira" pogwiritsa ntchito CO₂ yosungidwa ndi hydrogen yongowonjezwdwa. Komabe, methanol ndi poizoni ndipo ili ndi mphamvu yotsika ya calorific, yomwe imafuna thanki yayikulu yofanana.
Kapangidwe ka Sitima ndi Kugwiritsa Ntchito Mphamvu Mwachangu
Mphamvu zina zitha kukhala zothandiza kwambiri zikaphatikizidwa ndi kusintha kwa kapangidwe ka zombo. Zina mwazinthu zatsopano zomwe zimafala ndi izi:
- Kukonza mawonekedwe a chipolopolo kuti muchepetse kukana madzi.
- Kuyendetsa bwino, mwachitsanzo kugwiritsa ntchito zida zoyendetsera azimuth zokhala ndi mphamvu zowongolera mwanzeru.
- Machitidwe obwezeretsa mphamvu, kuphatikizapo kugwiritsa ntchito kutentha kotayira pa zombo zosakanikirana.
- Kuwongolera katundu m'mahotela, monga kugwiritsa ntchito ma LED, HVAC yosagwiritsa ntchito mphamvu zambiri, ndi makina owongolera anzeru.
- Zipangizo zopepuka komanso malo abwino kwambiri kuti zigwirizane ndi kulemera kwa mabatire kapena matanki ena amafuta.
Pa sitima zonyamula anthu, kugwiritsa ntchito mphamvu sikuchokera ku kuyendetsa kokha komanso ku zosowa za chitonthozo: mpweya woziziritsa, magetsi, ma elevator, mabwato, ndi machitidwe osangalatsa. Chifukwa chake, njira ya "sitima ngati dongosolo la mphamvu" ndiyofunikira—kuyang'anira kugwiritsa ntchito mphamvu zonse za sitimayo mwanjira yogwirizana.
Zomangamanga za Madoko ndi Zothandizira Zachilengedwe
Kupambana kwa zombo zina zogwiritsa ntchito mphamvu kumadalira kwambiri kukonzekera kwa madoko. Zombo zamagetsi zimafuna malo ochajira mwachangu, makina olumikizira okha, komanso mphamvu yokwanira ya netiweki. Hydrogen imafuna malo opangira kapena kugawa, malo osungira, ndi njira zapamwamba zotetezera. Ngakhale pa mafuta a biofuel kapena methanol, madoko ayenera kusintha matanki osungira, makina opopera, ndi kuwongolera zoopsa.
Kuwonjezera pa zomangamanga zakuthupi, pakufunika malamulo okhudza chilengedwe ndi anthu ogwira ntchito: miyezo yogawa zombo, satifiketi yachitetezo, maphunziro a ogwira ntchito, ndi njira zothandizira mwadzidzidzi. Popanda thandizoli, ngakhale ukadaulo wapamwamba umavutika kugwira ntchito mosalekeza.
Mavuto Okhudza Kukhazikitsa Ntchito M'munda
Ngakhale kuti kusintha kwa mphamvu m'zombo zonyamula anthu kumakumana ndi zopinga zazikulu zingapo. Ndalama zambiri zoyambira nthawi zambiri zimakhala chopinga kwa ogwira ntchito, makamaka m'misewu yokhala ndi malire ochepa. Kupezeka kwa zida zosinthira ndi akatswiri apadera kumakhalabe kochepa m'madera ena. Kuphatikiza apo, kusatsimikizika kokhudza kupezeka kwa mphamvu zobiriwira—kaya magetsi obwezerezedwanso, haidrojeni wobiriwira, kapena mafuta amagetsi—kumavuta kukonzekera kwanthawi yayitali.
Kumbali ina, kupita patsogolo kwa ukadaulo kukufulumira. Mitengo ya mabatire ikutsika, kugwiritsa ntchito bwino ma cell amafuta kukukwera, ndipo maboma ambiri akupereka zolimbikitsira kuchepetsa mpweya woipa. Izi zimatsegula mwayi kuti ukadaulo wina wamagetsi ukhale wopindulitsa chaka ndi chaka.
Tsogolo Loyera la Zombo Zonyamula Anthu
Ukadaulo wa zombo zonyamula anthu pogwiritsa ntchito mphamvu zina si njira yodziwika bwino, koma ndi sitepe yopita ku mayendedwe okhazikika apanyanja. Zombo zamagetsi zoyendetsedwa ndi mabatire zimachita bwino kwambiri panjira zazifupi zokhala ndi nthawi yokhazikika; machitidwe osakanikirana amapereka mlatho wosinthira wosinthika; haidrojeni ndi maselo amafuta amapereka mphamvu yotulutsa mpweya wochepa kwambiri mtsogolo; pomwe LNG, biofuels, ndi methanol ndi njira zomwe zingasinthidwe kuti zigwirizane ndi kukonzekera kwa zomangamanga komanso zofunikira panjira.
Mtsogolomu, kuphatikiza ukadaulo wambiri mwina ndiye yankho lenileni.
