Energy Implications of Electrotechnologies in Industrial Process Heating Systems
Industrial process heating (PH) systems consumed 7.5 quads of energy in 2014. These systems are predominately fuel-fired with over 87% of the total primary energy coming from fuel-based energy sources. The use of renewable/clean electricity offers an opportunity to decouple PH from direct fossil fuel use, reducing environmental footprints while saving energy. While electrically heated systems (electrotechnologies), are usually more efficient, provide better process control, and increase product quality; technological gaps and economic factors hinder their widespread adoption. This work explores the potential of current and emerging electrotechnologies to overcome these barriers and pave the path for electrification in major industries. Five industries with significant PH energy consumption are chosen and its heating requirements are studied for each manufacturing step. Possible electrotechnology alternatives (currently available and emerging) are identified for each step and the barriers associated with its large-scale implementation are investigated. Based on this analysis, appropriate routes of electrification are proposed for each industry and their potential impact on the national level energy consumption are quantified using a standardized methodology. This paper will present the electrification routes that are deemed feasible for each industry along with its quantitative impact on the use of electrical energy at national level. The technical details of the new systems and processes considered are also presented along with the barriers identified.
