The potential for carbon abatement in Taiwan's steel industry and an analysis of carbon abatement trends

摘要

This study applies a bottom-up approach to computation tree logic (CTL) by using mathematical relationships. According to a base scenario and a carbon abatement scenario, this study estimates the carbon abatement potential and costs in Taiwan's steel industry by drawing a carbon abatement cost curve for the years 2015, 2020, 2025, and 2030. In terms of short-term carbon abatement trends, the "existing carbon abatement technology that is undergoing steady growth and development" and the "currently popular carbon abatement technology that is facing transformational challenges" could be implemented immediately and should be the focus areas for research and development. In terms of long-term carbon abatement trends, if the steel industry in Taiwan were to implement the carbon abatement measures listed in this study, the amount of cost savings produced by energy conservations would be sufficient for covering the capital expenditure required for carbon reduction equipment. The carbon abatement cost curve in this study allows us to identify the carbon abatement measures that should be prioritized for the short, medium, and long terms, which would facilitate our development of a portfolio of carbon abatement measures, and provide a basis for the strategic analysis of carbon abatement technologies to the steel industry.
