Okutereka mu bbugumu
Okutereka ebbugumu lye maka agasinga okubeera n'obuzito obutono mu kulaba okutereka, kubanga teddamu kibuuzo "bbaatule ki" - kibuusabuusa oba bbaatule kye kikozesebwa ekituufu n'akatono.
Okutereka ebbugumu okutegeerekeka mu mazzi, ice oba omunnyo ogusaanuuse kukuze, kwa bbeeyi ntono buli yuniti y’amasoboza agaterekeddwa, era kuwangaala emyaka 25–30. Okutereka ebbugumu erikusike mu bintu ebikyusa phase-kuwa density eya waggulu ku bbugumu eriweereddwa, nga okukula kwawukana nnyo okusinziira ku bintu. Okutereka eddagala ly’ebbugumu kuwa density y’enzikiriziganya esinga obunene era okusinga kusigala ku mutendera gw’okunoonyereza.
Etteeka ly’okusalawo lyangu era litera okusubwa. Singa omugugu oguweebwa guba gwa bbugumu, nnyogovu oba omukka, ensalosalo y’enkola entuufu eba ya bbugumu. Okukyusa amasannyalaze okugatereka mu bbaatule n’okugakyusa okudda mu kuvuga chiller kitegeeza okusasula okufiirwa mu kukyusa emirundi ebiri ku mpeereza ttanka y’amazzi aganyogozeddwa-gy’etuusa butereevu. Ekifo ky’amakolero nga kyetaagisa 8 MWh-ebbugumu ekiro n’amasoboza g’enjuba mu ttuntu kirina okuba nga kisooka kugeraageranya maduuka g’ebbugumu, era nga kyongerako bbaatule singa wabaawo empeereza y’amasannyalaze ey’enjawulo eraga ensonga emu.
Ebitwala eddagala: Haidrojeni
Amaanyi ga haidrojeni aga 30–45%-okutuuka ku-amaanyi amalungi si kizibu kya yinginiya ekirindiridde okutereezebwa. Ye nsaasaanya ey’omunda ey’ekkubo eriyinza okukwata amaanyi okumala emyezi n’okuweereza obwetaavu nti amasannyalaze tegasobola kutuuka - emmere y’amakolero, ebbugumu ery’enkola ey’ebbugumu eringi-, entambula enzito.
Weekenneenye haidrojeni nga pulojekiti yeetaaga ebbanga lya sizoni, amaanyi agatambuzibwa, oba okuyungibwa wakati w’amasannyalaze n’ekitundu ekirala. Kikebere okusinziira ku bbaatule oluvannyuma lw’okukakasa nti bbaatule mu butuufu tesobola kutuukiriza bbanga lyetaagisa, kubanga ku bbanga lyonna bbaatule ly’esobola okuweereza, haidrojeni efiirwa ku bulungibwansi n’enjawulo ennene.
Okutereka Amasannyalaze
Supercapacitors zituusa okuddamu kwa millisecond n’obutitimbe bwa cycles ku 90–95% efficiency, nga amasoboza gapimiddwa mu seconds. Zino ze ky’okuddamu ekituufu ku mutindo gw’amaanyi, okuvuga-okuyita, ne frequency y’okuvuga obugaali eya waggulu ennyo, era eky’okuddamu ekikyamu ku kintu kyonna ekipimiddwa mu ssaawa. Okutereka amaanyi ga magineeti aga superconducting kusigala nga tekinologiya ow’okunoonyereza n’omukugu-okukozesa; ebyetaago bya cryogenic bikikuuma ebweru w’okugula pulojekiti mu bulambalamba.
