日本語
CASTは鉄鋼製造技術の費用を詳細に評価するボトムアップ型の技術経済モデルです。高炉、直接還元鉄、電気炉などの主要プロセスを網羅し、スクラップやDRIの配合も考慮します。中国、ドイツ、日本を対象に、資本コスト、エネルギー価格、炭素価格などの前提を変えたシナリオ分析が可能で、鉄鋼セクターの脱炭素経路の研究や政策分析を支援します。
English
CAST is a bottom-up techno-economic model for estimating itemized production costs of iron and steelmaking technologies. It covers main processes from ironmaking to steelmaking, allowing users to quantify costs with blends of hot metal, DRI, and scrap. Scenario analysis across financial, commodity, and policy assumptions is supported, with default data for China, Germany, and Japan. The tool aids research, policy analysis, and stakeholder engagement on steel decarbonization pathways.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の鉄鋼業は世界有数の排出量を抱え、水素還元やCCUSなどの革新的技術の開発が進む。本モデルは、炭素価格や技術選択がコスト構造に与える影響を定量的に示すことで、日本の政策立案や企業の投資判断に示唆を与える。特に、GX推進やカーボンプライシング導入の議論に有用なツールとなる。
In the global GX context
Globally, steel decarbonization is critical for meeting climate targets, and carbon pricing mechanisms are expanding. CAST provides a transparent, comparable framework for assessing technology costs across major steel-producing countries, supporting policy analysis and corporate strategy. It enables stakeholders to evaluate the impact of carbon pricing and technology choices on cost competitiveness, informing transition finance and investment decisions.

📄 Abstract（原文）
CAST is a bottom-up techno-economic model for estimating itemized production costs of iron and steelmaking technologies. It covers the main production processes, from ironmaking (blast furnace, direct reduction of iron, and electric smelting furnace) to steelmaking (basic oxygen furnace and electric arc furnace). The tool also allows users to quantify the cost of steelmaking using a blend of hot metal, direct reduced iron, and scrap. CAST supports scenario analysis across a wide range of financial, commodity price, and policy assumptions. Default data are provided for three countries — China, Germany, and Japan — and users can adjust key assumptions, such as capital investment by technology, energy prices, raw material costs, carbon pricing, and technology choice, to see how cost structures, cost differences, and emissions intensities respond in real time. The tool is intended to support research, policy analysis, and stakeholder engagement on steel sector decarbonization pathways.
