Carbon Capturing

Abstract

Um die vorgegebenen Klimaziele zu erreichen, bedarf es einer skalierten Anwendung von Negative Emission Technologies. Diese können das, in der Atmosphäre befindliche, Kohlenstoffdioxid einfangen und langfristig speichern. Die Literatur zeigt, dass es bereits einige Technologien wie beispielsweise BECCS, Direct Air Capturing oder Enhanced Rock Weathering gibt und diese ein großes Potenzial für die globale CO2-Reduktion haben. Da diese Technologien in skalierten Maßstab ausgerollt werden müssen, werden gewisse ökonomische Rahmenbedingungen benötigt. Diese Arbeit befasst sich daher mit den wichtigsten Regulierungsmaßnahmen, damit die Technologien DAC und ERW zu etablierten Methoden der CO2-Reduktion werden. Hierfür wurde eine qualitative, induktive Methodik herangezogen, um die Zusammenhänge der jeweiligen Wechselwirkungen besser verstehen zu können. Es wurden sieben Expert:innen zu der Thematik der NETS und Rahmenbedingungen befragt. Die Ergebnisse dieser Arbeit zeigen, dass speziell für diese beiden Methoden Förderungen für Forschung und Entwicklung sowie Standards und eine CO2-Steuer den größten Einfluss auf die globale Etablierung der Technologien haben. Zudem sei es wichtig, die soziale Akzeptanz der Bevölkerung zu erlangen und Nischenmärkte für den Voluntary Offset Markt zu gründen und regulieren.

In order to achieve the specified climate targets, a scaled-up application of Negative Emission Technologies is required. These can capture the carbon dioxide in the atmosphere and store it for the long term. Literature shows that some technologies such as BECCS, Direct Air Capturing or Enhanced Rock Weathering already exist and have great potential for global CO2 reduction. Since these technologies need to be scaled to become profitable, specific economic conditions are needed. This paper therefore addresses the key regulatory measures for the technologies DAC and ERW to become established methods of CO2 reduction. For this purpose, a qualitative, inductive methodology was used to better understand the interrelationships of the respective technologies and the effect of different economic conditions. Seven experts were interviewed on the topic of NETS and framework conditions. The results of this work show that especially for these two methods, subsidies for research and development as well as standards and a CO2 tax have the greatest influence on the global establishment of the technologies. Furthermore, it is important to gain the social acceptance of the population and to establish and regulate niche markets for the voluntary offset market.
