Abstract (Swedish)
Industrial processes currently account for a significant share (25–35 %) of the world’s total energy demand and related emis- sions. During recent years, the amount of low-carbon electric- ity from renewable energy sources (such as wind and solar) has increased continuously. There is therefore an increasing inter- est in electrification of industrial processes in order to achieve long-term decarbonisation goals.
Structural changes in the capital-intensive processing in- dustry take a long time to implement. Furthermore, the num- ber of possible technologies and systems for electrification of industrial processes is high, and different technologies and combinations of technologies will have different performance both in terms of economy...

Structural changes in the capital-intensive processing in- dustry take a long time to implement. Furthermore, the num- ber of possible technologies and systems for electrification of industrial processes is high, and different technologies and combinations of technologies will have different performance both in terms of economy and carbon footprint. For indus- trial decision-makers, it is important both to understand such systemic effects of electrification technologies and to discard low-performing candidates at an early stage. So far, studies on industrial electrification have focused on top-down approaches using explorative scenarios for analysing the consequences of a sector-wide full electrification assuming greenfield invest- ments. There is a lack of studies adopting a bottom-up per- spective for investigation of partial electrification options in brownfield investments at existing sites including process inte- gration aspects and system consequences as well as the impacts on overall energy efficiency.
The objective of this paper is to propose a methodology for bottom-up assessments of industrial electrification options and to demonstrate this methodology with a case study. For this purpose, a bottom-up methodology that especially accounts for the systematic effects of increased electrification on a plant level was developed and then applied to the steam system of an oil refinery plant in Sweden. The results show that the energy and carbon footprint consequences of such measures are hard to pre- dict without detailed modelling studies since industrial process unit operations are highly interlinked. Furthermore, the results from the techno-economic as well as carbon footprint bottom- up assessments can be used to compare electrification with other decarbonisation options and to formulate detailed roadmaps for decarbonization of energy-intensive industrial processes.
