Modelling Long-Term Industry Energy Demand and CO2 Emissions in the System Context Using REMIND (Version 3.1.0)

Michaja Pehl, Felix Schreyer, and Gunnar Luderer

Abstract. This paper presents the extension of industry modelling within the REMIND integrated assessment model to industry subsectors, and the projection of future industry subsector activity and energy demand for different baseline scenarios for use with the REMIND model. The industry sector is the largest greenhouse gas-emitting energy demand sector and considered a mitigation bottleneck. At the same time, industry subsectors are heterogeneous and face distinct emission mitigation challenges. By extending the multi-region, general equilibrium integrated assessment model REMIND to an explicit representation of four industry subsectors (cement, chemicals, steel, and other industry production), along with subsector-specific carbon captrure and sequestration (CCS), we are able to investigate industry emission mitigation strategies in the context of the entire energy-economy-climate system, covering mitigation options ranging from reduced demand for industrial goods, over fuel switching and electrification, to endogenous energy efficiency increases and carbon capture. We also present the derivation of both activity and final energy demand trajectories for the industry subsectors for the use with the REMIND model in baseline scenarios, based on short-term the continuation of historic trends and long-term global convergence. The system allows for selective variation of specific subsector activity and final energy demand across scenarios and regions to create consistent scenarios for a wide range of socioeconomic drivers and scenario story lines, like the shared socioeconomic pathways (SSPs).

Short summary
We extend the REMIND model (used to investigate climate mitigation strategies) by an industry module that represents cement, chemicals, steel, and other industry. We also present a method for deriving scenarios of industry subsector activity and energy demand, that are consistent with established socioeconomic scenarios. This allows us to investigate the different climate change mitigation challenges and strategies in industry subsectors in the context of entire energy-economy-climate system.
