Abstract: | Technology development is a sophisticated process including multiple development phases. Already the research phase as the first phase of the development process can significantly determine the later technical, economical and environmental performance of a technology. Due to the high environmental impact of technologies during their life cycle, the use of sustainability analysis methodologies in an early stage of technology development seems valuable. Life Cycle Assessment (LCA) is a methodology to analyze the environmental impact of products during their whole life cycle. This methodology was originally developed to compare different yet functionally analogous products, such as tetra packs and glass bottles. In the last 20 years, life cycle based product analysis became increasingly popular and was adapted to new application fields requiring adaptation also of the LCA methodology itself. Thus, multiple new approaches and methodologies were developed. Due to the lack of a uniform scientific LCA approach, a general LCA methodology towards the analysis of different product types and application fields (i.e. technology development) is currently unavailable. The present work examines the application of LCA in technology development. The study includes an analysis of existing methodological approaches, and the identification of technology-specific requirements for the LCA on the example of a case study. In addition, a new method for the application of LCA in the development of a new technology was designed and successfully applied to the case study. As an example for the development of a complex technology, a microreactor for Fischer-Tropsch synthesis (FTS) in a Gas-to-Liquid (GtL) process was chosen as a case study. The focus of the theoretical work lies in the modeling of the technology development process and how to deal with different models in LCA and technology development. Based on the general systems theory, a model of microreactor development was created. Subsequently, a method for the application of LCA on the model of micro-reactor development was developed. Using this novel methodology, four phases of the microreactor development were analyzed by LCA; design and manufacturing, use of a microreactor for the FTS, application of the microreactor in the GtL process and application of the GtL process for the substitution of gas flaring in offshore oil production. The LCA results obtained with the new methodology provide evidence on environmental effects of various design configurations of the technology under development throughout the development process. The application of this new methodology during the microreactor development process for the first time allows the creation of environmentally optimized GtL processes for site-specific oil production. |
