  • Müllverbrennung: Keine Methanol-Produktion in Zella-Mehlis - inSüdthüringen

    1 month ago | insuedthueringen.de | Hanno Böck

    Die Verbrennung von Abfällen wird in Deutschland häufig genutzt, um Strom und Fernwärme zu erzeugen. Doch dabei entsteht viel klimaschädliches Kohlendioxid. Schon seit etwa einem Jahrzehnt plante man daher an der Müllverbrennungsanlage (Raba) Zella-Mehlis, einen Teil des dabei entstehenden Kohlendioxids zu nutzen. Mithilfe von grünem Wasserstoff, der durch die Spaltung von Wasser mit Strom erzeugt werden kann, wollte man das Kohlendioxid zu Methanol umwandeln.

In recent years,there has been considerable interest in alternative shipping fuels derivedfrom green hydrogen — like methanol or ammonia. But what about hydrogen itself? Is green hydrogen a suitableshipping fuel? And if so, what could its role be in a futureclimate-neutral shipping industry? The shipping industry is, of course, operating under very diversecircumstances.
