Abstract

Die Bedeutung von Wasserstoff auf dem Weg hin zur Klimaneutralität wird deutlich ansteigen und es ist von einer enormen Erhöhung des Bedarfs auszugehen. Wasserstoff wird gegenwärtig überwiegend aus fossilen Brennstoffen hergestellt. Deshalb werden Technologien zur kohlenstoffarmen Herstellung wichtiger: Dazu zählt neben dem blauen Wasserstoff vor allem der sogenannte grüne Wasserstoff unter Nutzung erneuerbarer Energien. Perspektivisch soll grüner Wasserstoff den auf Basis von fossilen Quellen hergestellten Wasserstoff ersetzen, dies bedingt allerdings dessen Wettbewerbsfähigkeit bei der Herstellung. Die Herstellungskosten hängen maßgeblich von den Stromkosten bzw. -preisen, der Investition in den Elektrolyseur, dem Elektrolyseurwirkungsgrad sowie den Betriebsstunden des Elektrolyseurs ab. Im Folgenden soll deshalb ein kurzer Überblick über den Stand der Elektrolyseure und die Herstellungskosten von grünem Wasserstoff gegeben werden. Zudem wird auch skizziert, welche Wasserstoffbedarfe in Deutschland erwartet werden.
