This Master Thesis research addresses strategies for deploying sustainable aircraft technologies, with the primary goal to accelerate sustainability transitions within the aviation industry. The focus of the research is on analysing hydrogen and ultra-efficient aircraft technologies in comparison to a conventional aircraft, with 50% SAF drop-in, as the benchmark technology.

The Technological Innovation System (TIS) framework, viewed from a company perspective, serves as the basis for this research. The TIS framework can be defined as "the network of actors interacting within the industry, subject to certain institutions and involved in the generation, diffusion, and utilisation of a novel innovation." Through the examination of seven essential dimensions, referred to as TIS building blocks, the most significant bottlenecks impeding the implementation of hydrogen and ultra-efficient aircraft have been identified.

This knowledge has been utilised to create a three-phased deployment strategy for both sustainable aircraft technologies, considering timing and scale. The research scope has focused on the regional market segment, using a 70-90 passenger Embraer 175 aircraft design as reference aircraft. Key insights from the research have led to proposed recommendations to industry stakeholders, policy-makers and academics.
