Study / Potential for electrification of industrial thermal processes - Phase 1
In the current context of industrial decarbonisation in France, process electrification is one of the solutions to be considered given the particularity of the French energy mix. In its National Low-Carbon Strategy (SNBC), France has set a target of 70% electrification of its industry by 2050 (final energy). In this context, ALLICE wished to shed light on the electrification potential of various industrial thermal processes, the profitability of electrical solutions (in substitution or in coupling with fossil energy technologies) and the avenues of innovation necessary to lift the technical and economic barriers. The realization of this collective study was entrusted to CETIAT and Cetim.
The study has prioritised five representative thermal processes covering different industrial sectors: pasteurisation, evapo-concentration, high- and low-temperature batch ovens, high- and low-temperature tunnel ovens, tunnel dryer. For each process are detailed:
The study has prioritised five representative thermal processes covering different industrial sectors: pasteurisation, evapo-concentration, high- and low-temperature batch ovens, high- and low-temperature tunnel ovens, tunnel dryer. For each process are detailed:
- The identification and characterization of compatible electrical technologies
- A detailed techno-economic analysis of the partial or total substitution of fossil fuels by electrical solutions for the targeted processes, with sensitivity analyses to take into account the impact of changes in energy costs and relative to the carbon tax
- Tangible feedback from the process studied
The conclusions of these techno-economic analyses highlight the advantages and obstacles to electrification, taking into account the specific features of each process. One of the major benefits of this study is to have this process-oriented analysis, and the positioning of each electrical technology with regard to operating criteria in the field. Indeed, the technical conditions of the processes have a strong impact on the viability or not of the electrical alternatives.
