Cercet\u0103tori de la Universitatea California din Santa Barbara au dezvoltat un lichid care stocheaz\u0103 energia solar\u0103 \u00een leg\u0103turi chimice, scrie ScienceBlog<\/a><\/span>.<\/p>\n

Descoperirea ar putea transforma modul \u00een care este realizat\u0103 stocarea energiei regenerabile, elimin\u00e2nd nevoia bateriilor tradi\u021bionale. \u00cen loc s\u0103 transforme lumina \u00een electricitate, sistemul stocheaz\u0103 direct c\u0103ldura \u00eentr-o molecul\u0103 special conceput\u0103.<\/p>\n

Oamenii de \u0219tiin\u021b\u0103 spun c\u0103 inova\u021bia ar putea permite \u00eenc\u0103lzirea locuin\u021belor f\u0103r\u0103 emisii de carbon.<\/p>\n

Cum func\u021bioneaz\u0103 sistemul de stocare solar\u0103 molecular\u0103<\/h2>\n

Tehnologia se bazeaz\u0103 pe o molecul\u0103 numit\u0103 pirimidon\u0103. C\u00e2nd este expus\u0103 la lumin\u0103 solar\u0103, molecula \u00ee\u0219i schimb\u0103 forma \u0219i intr\u0103 \u00eentr-o stare de energie ridicat\u0103. Ea r\u0103m\u00e2ne stabil\u0103 \u00een aceast\u0103 form\u0103 \u201e\u00eenc\u0103rcat\u0103\u201d p\u00e2n\u0103 c\u00e2nd este declan\u0219at\u0103 eliberarea c\u0103ldurii stocate.<\/p>\n

Un stimul mic, precum c\u0103ldura sau un acid, determin\u0103 revenirea la forma ini\u021bial\u0103 \u0219i eliberarea energiei. Conceptul este cunoscut sub numele de Molecular Solar Thermal (MOST), adic\u0103 stocare solar\u0103 molecular\u0103 a energiei termice.<\/p>\n

Spre deosebire de bateriile litiu-ion, lichidul nu pierde treptat energia acumulat\u0103. Cercet\u0103torii spun c\u0103 energia poate fi stocat\u0103 ani de zile f\u0103r\u0103 degradare.<\/p>\n

Sistemul func\u021bioneaz\u0103 ca un arc \u00eenc\u0103rcat cu c\u0103ldur\u0103 solar\u0103, gata de utilizare la cerere.<\/p>\n

Inspirat din ADN \u0219i proiectat pentru eficien\u021b\u0103<\/h2>\n

Designul molecular a fost inspirat de procese naturale din ADN. Cercet\u0103torii au imitat o modificare structural\u0103 numit\u0103 izomer Dewar. Aceast\u0103 abordare a dus la crearea unei molecule sintetice u\u0219oare \u0219i compatibile cu apa.<\/p>\n

Noul sistem atinge o densitate energetic\u0103 de 1,6 megajouli pe kilogram. Prin compara\u021bie, bateriile litiu-ion stocheaz\u0103 aproximativ 0,9 megajouli pe kilogram. Cercet\u0103torii spun c\u0103 performan\u021ba este aproape dubl\u0103.<\/p>\n

\u00cen teste de laborator, o jum\u0103tate de mililitru de lichid a generat suficient\u0103 c\u0103ldur\u0103 pentru a fierbe ap\u0103. Oamenii de \u0219tiin\u021b\u0103 au numit experimentul \u201etestul fierb\u0103torului\u201d, considerat un pas major pentru tehnologia MOST.<\/p>\n

Aplica\u021bii posibile \u0219i pa\u0219ii urm\u0103tori<\/h2>\n

Echipa \u00ee\u0219i imagineaz\u0103 colectoare solare montate pe acoperi\u0219uri care \u00eencarc\u0103 lichidul pe timpul zilei. Fluidul \u00eenc\u0103lzit ar putea fi apoi stocat \u00een rezervoare izolate pentru utilizare nocturn\u0103.<\/p>\n

Sistemul ar putea furniza ap\u0103 cald\u0103 \u0219i \u00eenc\u0103lzire f\u0103r\u0103 combustibili fosili. \u00cen prezent, molecula absoarbe \u00een principal lumin\u0103 ultraviolet\u0103, ceea ce \u00eei limiteaz\u0103 eficien\u021ba.<\/p>\n

Cercet\u0103torii lucreaz\u0103 la adaptarea acesteia pentru a absorbi mai mult\u0103 lumin\u0103 vizibil\u0103.<\/p>\n

Dac\u0103 va avea succes, tehnologia ar putea deveni o alternativ\u0103 scalabil\u0103 la metodele conven\u021bionale de stocare a energiei.<\/p>\n","protected":false},"excerpt":{"rendered":"
