Abstract [sv]

Detta projekt handlar om implementationen av högtemperaturs värmepumpar i järn- och stålindustrin i Sverige. Industrin både konsumerar stora mängder energi och släpper ut stora mängder växthusgaser. För att nå FN:s och Sveriges framtida mål kommer industrin behöva effektiviseras. Högtemperaturs värmepumpar kan ge betydande bidrag både till värmeåtervinning och till att minska energiförbrukning.

Målet med studien är att kartlägga järn- och stålindustrins processer och energianvändning i Sverige för att se huruvida en övergång till högtemperaturs värmepumpar skulle effektivisera industrin. För att undersöka detta har en litteraturstudie genomförts i kombination med tre intervjuer. De företagen som intervjuades var Jernkontoret, Ovako AB och Uddeholms AB.

Utifrån litteraturstudien och intervjuerna framstår det som att det i dagsläget skulle vara både svårt och ineffektivt att implementera högtemperaturs värmepumpar i den skrotbaserade stålindustrin i Sverige. Men med en del beräkningar och antaganden verkar det som att implementationen skulle kunna vara både möjlig och effektiv i framtiden.

Abstract [en]

This project is about the implementation of High Temperature Heat Pumps (HTHP) in the iron and steel Industry in Sweden. The industry is both a large energy consumer and a large greenhouse gas emitter. To reach both the UN:s and Sweden's own future goals, the industry must increase their efficiency. High temperature heat pumps can give a significant contribution to improve heat recovery and to decrease energy consumption.

The goal of this study is to map the iron and steel industries processes and energy consumption in Sweden to see if a change to high temperature heat pumps would increase efficiency in the industry. The method used was a combination of a literature study and three interviews. The interviewed companies were Jernkontoret, Ovako AB and Uddeholms AB.

The results from the literature study and the interviews indicate that it seems as if the implementation of high temperature heat pumps would be both hard and ineffective in the current situation in the scrap-based steel industry in Sweden. However, with some additional calculations and assumptions it seems like the implementation would be both possible and effective in the future.
