Uus vesinikutootmise meetod vajab 6 korda v\u00e4hem elektrit kui praegu vaja l\u00e4heb!<\/h3>\n\n\n\n

Chicago Illinoisi \u00fclikooli (UIC) teadlased on v\u00e4lja t\u00f6\u00f6tanud uue meetodi vesiniku eraldamiseks veest, kasutades p\u00e4ikeseenergiat ning p\u00f5llumajandusj\u00e4\u00e4tmeid ja s\u00f5nnikut. <\/p>\n\n\n\n

Teadlaste s\u00f5nul v\u00e4hendab meetod vesiniku tootmiseks vajalikku energiahulka 600%. <\/strong>Tulemused on avaldatud ajakirjas Cell Reports Physical Science<\/em>.\u00a0<\/p>\n\n\n\n

Meetod kasutab s\u00fcsinikurikast ainet, et v\u00e4hendada veest vesiniku eraldamiseks vajalikku elektrihulka. “See on transformatiivne tehnoloogia,” \u00fctlevad teadlased.<\/p>\n\n\n\n

Elektrol\u00fc\u00fcs on vesinikk\u00fctuse eluts\u00fckli k\u00f5ige kallim etapp, moodustades umbes 80% kuludest. Hiljutised edusammud vesiniku tootmisel on v\u00e4hendanud vee l\u00f5hustamiseks vajalikku pinget, lisades reaktsiooni s\u00fcsinikuallika. Selle protsessi k\u00e4igus kasutatakse aga sageli kivis\u00fctt v\u00f5i kalleid rafineeritud kemikaale ning k\u00f5rvalsaadusena tekib s\u00fcsinikuheide.<\/p>\n\n\n\n

UIC teadlased muutsid protsessi nii, et kivis\u00f6e asemel saab\u00a0s\u00fcsinikuallikana kasutada tavalistest j\u00e4\u00e4tmetest p\u00e4rit biomassi. Segades v\u00e4\u00e4velhapet p\u00f5llumajandusj\u00e4\u00e4tmete, loomsete j\u00e4\u00e4tmete ja kanalisatsioonist saadud massiga, tekitasid nad reaktsioonis kasutatava l\u00e4ga.<\/p>\n\n\n\n

Meeskond katsetas mitmeid erinevaid s\u00fcsinikuallikaid, sealhulgas suhkruroo- ja kanepij\u00e4\u00e4tmeid, paberij\u00e4\u00e4tmeid, lehmas\u00f5nnikut. K\u00f5ik viis sisendit v\u00e4hendasid elektrol\u00fc\u00fcsi l\u00e4biviimiseks vajalikku v\u00f5imsust, kuid parim tulemus saadi lehmas\u00f5nnikuga, mis v\u00e4hendas elektrivajadust 600% ehk ligi viiendiku voldini.<\/p>\n\n\n\n

V\u00e4hendatud pingega suutsid UIC teadlased tekitada elektrol\u00fc\u00fcsireaktsiooni \u00fche tavalise p\u00e4ikesepaneeli abiga, mis genereeris umbes 15 milliamprit voolu pingel 0,5 V, mis on v\u00e4hem kui AA-patarei toodetav v\u00f5imsus.<\/p>\n\n\n\n

“See on v\u00e4ga t\u00f5hus, kuna peaaegu 35% s\u00fcsinikuallikast ja p\u00e4ikeseenergiast muundatakse vesinikuks,” \u00fctles uuringu kaasautor Rohit Chauhan. Chauhan \u00fctles, et bioloogilise materjali kasutusm\u00e4\u00e4r on maailmarekord.<\/p>\n\n\n\n

Uurimisr\u00fchm \u00fctles, et selline j\u00e4\u00e4tmekasutus v\u00f5ib p\u00f5llumeeste jaoks kujuneda uueks tuluallikaks ning tekitab v\u00f5imaluse olla energia m\u00f5ttes iseseisev ja autonoomne. <\/p>\n\n\n\n

Orochem Technologies Inc. taotleb meetodile patenti ja teadlased kavatsevad katsetada meetodeid suuremas mahus. Selles uuringus osalesid ka Stanfordi \u00dclikool, Texase Tehnika\u00fclikool, India Tehnoloogiainstituut Roorkee ja Korea \u00dclikool.<\/p>\n\n\n\n
