Research of the spatial and temporal diffusion of technologies and their performance trends offers important insights for patterns, drivers, and constraints of future technological change, for instance, that required to achieve climate stabilization. The research project aims to further the understanding of the historic change of such technologies which could present analogies for new environmental add-on technologies (e.g. carbon capture and storage, direct air capture).
Following the methodology of Wilson (2009), a historic scaling dynamics analysis was conducted for a range of chemical industry production processes (e.g., for ammonia, ethylene, benzene, chlorine, caustic soda). A 3-parameter logistic function was fitted to time-series data at industry and unit levels using IIASA's LSM2 software. The estimated parameters (saturation level, infliction point, time period over which y grows from 10% to 90% of the saturation level) allow for comparison of the rates and extent of scaling between the industry and unit levels of a technology as well as between different technologies. Linking production capacity to the energy intensity of production over time enables comparability of the extent and rates of scaling of chemical industry technologies with scaling patterns found, for example, for energy technologies.
The analysis is highly dependent on data availability and quality. Data search and preparation turned out to be very time-consuming, so that at this point only preliminary results are available. (Originally, the project had envisaged a cost trend analysis of environmental add-on technologies for traditional air pollutants - like flue gas desulphurization units, in Germany and Japan.) A lack of publicly accessible cost data inhibited the continuation of this line of research. Preliminary results suggest similar scaling dynamics of chemical industry technologies to the ones found for energy technologies. An analysis of the relation of cost dynamics and scaling dynamics is yet to be performed.
