Majhne kinetične vodne turbine, mogoče postavitve in ekonomska učinkovitostPredin, Andrej, 1961- ; Hren, GorazdV prispevku je zbran pregled majhnih kinetičnih turbin, primernih za reke v Sloveniji, in njihove tehnologije. V zadnjem desetletju se pojavljajo predvsem v deželah, bogatih s hidroenergetskim ... potencialom (Kanada, ZDA, UK..), žal brez ekonomskega vrednotenja škodljivih posegov v rečni habitat pri klasičnih postavitvah, kot so hidrokinetične turbine, še posebno manjše, ki so ekonomsko manj zanimive. Zaradi relativno nizke proizvodnje, ki izvira predvsem iz dejstva, da se ne izkorišča celoten hidroenergetski potencial reke, ampak samo dinamični del, so hidrokinetične turbine investicijsko gledano razmeroma drage. Če želimo povečati hidroenergetski izkoristek, so potrebne izvedbe z več agregati, ki večajo tudi investicijske, obratovalne in vzdrževalne stroške. Prav slednje je razlog, da se te tehnologije ne razvijajo in se komercialno ne uveljavljajo tako hitro, kot bi pričakovali. Ker smo vse bolj odgovorni do okolja, bomo prisiljeni razvijati in uporabljati tehnologije, katerih kratkoročni donosi so majhni, dolgoročni vpliv na okolje pa pozitiven. Avtorja meniva, da je to področje raziskovalna in tehnološka priložnost za Slovenijo.Source: URE, energetika in okolje = Energy efficiency, energy and environment (Str. 143-149)Type of material - article, component partPublish date - 2013Language - slovenianCOBISS.SI-ID - 76815873
