Az acélipar zöld átállásának technológiai áttekintése, annak műszaki gazdasági vonatkozásai
Absztrakt
A vas- és acélipar felelős a világ üvegházhatású gázkibocsátásának több mint 7%-áért. A Párizsi Megállapodás hőmérsékleti céljainak elérése érdekében a CO2-kibocsátás drasztikus csökkentésére van szükség. Számos alacsony vagy nulla CO2-kibocsátású vas- és acélgyártási projekt van tervben vagy folyamatban a zöldacél előállítása érdekében. Számos megközelítés létezik a szén-dioxid-kibocsátás jelentős csökkentésének elérésére az acéliparban, mint körforgásos gazdaság, illetve az egyes technológiák CO2-csökkentésére és közvetlen szén-dioxid-kibocsátás elkerülése is. A vas- és acélipar zöld átállásának viszont számos műszaki-gazdasági vonatkozása van a technológia, infrastruktúra, tőke, működési költségek, kereslet és a politikai irányelvek szempontjaiból. Az átállás globális kihívást jelent, amely globális választ tesz szükségessé.
