Die Energiewende erfordert Technologien zur Reduzierung der Treibhausgasemissionen. Verschiedene Sektoren, darunter Landwirtschaft, Industrie und Verkehr, setzen Wasserstofftechnologien ein. Der Wasserstoff-Farbkreis erm\u00f6glicht die Kodifizierung von Erzeugungstechnologien. Jede Wasserstofffarbe hat einen eigenen Produktionsweg, der unterschiedliche Mengen an Treibhausgasemissionen erzeugt. <\/p>\n\n\n\n
\n
Grauer\/brauner\/schwarzer Wasserstoff, der durch die Verbrennung fossiler Brennstoffe, vor allem Erdgas und Kohle (braun aus Braunkohle), erzeugt wird, verursacht den Aussto\u00df von bis zu 20 Tonnen Kohlendioxid pro Tonne Wasserstoff. Dieser Farbpfad macht 90 Prozent der weltweiten Wasserstoffproduktion aus.<\/li>\n\n\n\n
Blauer Wasserstoff, der durch die Kombination von grauem Wasserstoff und Kohlenstoffabscheidung und -speicherung (CCS) sowie Kohlenstoffabscheidung, -nutzung und -sequestrierung (CCUS) erzeugt wird, vermeidet die meisten Treibhausgasemissionen.<\/li>\n\n\n\n
T\u00fcrkisfarbener Wasserstoff, der durch Pyrolyse von Methan entsteht, erzeugt Wasserstoff und festen Kohlenstoff.<\/li>\n\n\n\n
Gr\u00fcner Wasserstoff, der aus erneuerbaren Energiequellen wie Bioenergie, Sonne und Wind gewonnen wird, ist emissionsfrei. Seine Herstellung ist derzeit jedoch teuer. <\/li>\n\n\n\n
Gelber (oder violetter) Wasserstoff, der durch Elektrolyse von Strom aus Kernkraftwerken oder anderen Stromquellen entsteht, kann im Vergleich zu blauem oder gr\u00fcnem Wasserstoff h\u00f6here Emissionen verursachen. <\/li>\n\n\n\n
Rosa\/violett\/roter Wasserstoff entsteht durch Elektrolyse mit Kernenergie. Die Kohlenstoffintensit\u00e4t ist ausgezeichnet, da dieser Prozess keinerlei Kohlenstoffemissionen verursacht. Soziale, politische und sicherheitsrelevante Bedenken beeintr\u00e4chtigen jedoch die Produktion. <\/li>\n\n\n\n
Wei\u00dfer Wasserstoff ist geologisch und nat\u00fcrlich vorkommend. Es gibt jedoch nur begrenzte M\u00f6glichkeiten, diese potenziell CI-freundliche Form von Wasserstoff zu gewinnen und zu nutzen.<\/li>\n<\/ol>\n\n\n\n<\/figure>\n\n\n\n
Darin liegt eine entscheidende Herausforderung f\u00fcr den erfolgreichen \u00dcbergang zu einer kohlenstoffarmen Wirtschaft. Da sich Energiesysteme zunehmend von zentralisierten zu dezentralisierten, von \u201egrauen\u201c zu \u201egr\u00fcnen\u201c Systemen entwickeln, m\u00fcssen die Beteiligten Emissionen und gr\u00fcne Molek\u00fcle effizient erfassen und verfolgen k\u00f6nnen \u2013 und zwar auf transparente, sichere und standardisierte Weise \u2013 und zwar entlang der Wertsch\u00f6pfungsketten von der Produktion bis zum Verbrauch.<\/p>\n\n\n\n
Insgesamt wird die Geschwindigkeit, mit der die Kosten f\u00fcr gr\u00fcnen Wasserstoff sinken, von staatlichen Ma\u00dfnahmen und Anreizen abh\u00e4ngen, wie etwa der CO2-Bepreisung und Steuergutschriften.<\/p>","protected":false},"excerpt":{"rendered":"
