Potentials for Saving Energy and CO2-emission through the Use of EPM Technologies
The paper demonstrates how electromagnetic processing of materials(EPM)provides significant opportunities for saving primary energy and reducing carbon emissions in industrial thermal processes.Potentially electricity can replace up to 100%of other energy carriers currently used for process heat.For the time horizon from now to the year 2050 a transition scenario is developed and described.In this scenario the industrial processes are gradually switched from the actual situation to a situation with 100%electrically operated industrial processes.The developed scenarios take into account the most energy intensive industrial thermal processes,which could be replaced by electrothermal technologies and offer obviously the biggest future potential in terms of saving of primary energy and reducing of carbon emissions.As the average primary energy factor(PEF)gradually decreases from 2.5 currently,to 1 for a 100%renewable electricity system,the benefits of EPM will gradually increase.For each step in the development of the PEF the annual primary energy savings and annual reductions in greenhouse gas emissions are calculated and described in this paper.
