本研究は、インド・ジャムリアの製鉄所を対象に、太陽光・風力・蓄電池・ディーゼルバックアップを組み合わせたハイブリッド再生可能エネルギーシステムを用いて、グリーン水素を製造し低炭素鋼を生産するマイクロパイロットスケールの技術経済性評価を実施。結果として年間50kgのグリーン水素を生成し、1トンの低炭素鋼を生産可能であるが、水素製造コストは52.40ドル/kgと高く、スケールアップによるコスト低減が課題。CO2排出量は従来のコークス法と比較して99.98%削減され、技術的実現可能性を示した。
English
This study conducts a techno-economic assessment of a micro-pilot green hydrogen-based decarbonization scenario for steel production in Jamuria, India, using a hybrid renewable system (solar, wind, battery, diesel backup). The system produces 50 kg of green hydrogen annually, enabling 1 ton of low-carbon steel. The levelized cost of hydrogen is $52.40/kg, high due to scale, but CO2 emissions are reduced by 99.98% compared to traditional coke-based steelmaking, demonstrating technical feasibility.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも鉄鋼業の脱炭素は急務であり、グリーン水素を用いた製鉄技術（COURSE50など）が注目されている。本研究成果は、インドの事例ではあるが、再生可能エネルギーと水素製造を組み合わせたシステム設計や経済性評価の枠組みを提供しており、日本国内でのスケールアップやコスト低減の検討に参考となる。
In the global GX context
Globally, steel decarbonization is critical for net-zero targets, and green hydrogen is a key pathway. This pilot study provides replicable techno-economic parameters and scaling thresholds that inform similar efforts worldwide, particularly for integrating renewable energy with hydrogen production in heavy industry.

📄 Abstract（原文）
This work provides a micro-pilot techno-economic and environmental assessment of a green hydrogen-driven decarbonization scenario for low-carbon steel production at the capacity of 1 ton steel produced (i.e., requiring 50 kg of green hydrogen). In this work an integrated renewable energy (RE) scenario for the steel production site at Jamuria, West Bengal, India is planned to utilize solar photovoltaic (PV), wind turbines (WTs), battery storage and a diesel backup generator to meet the hydrogen production load from an electrolyzer using HOMER Pro software. The results show that the proposed micro-pilot system produces excess electricity with respect to the plant's operating demand (i.e., 3,297,719 kWh/year), allowing for the realization of 50 kg/year of green hydrogen that could be converted into the production of low-carbon steel at a scale of 1 ton. At pilot scale, the levelized cost of hydrogen (LCOH) is calculated at $52.40/kg due to the lack of economies of scale but it is anticipated that this will fall dramatically upon industrial deployment. Most importantly, the process succeeds in emitting nearly zero direct CO₂, however, the only source was 23.1 kg/year from a backup diesel generator for periods of extreme renewable intermittency, achieving a radical reduction in emissions of 99.98% when compared to traditional coke-based steelmaking. These outcomes suggest the technical feasibility of renewable-driven hydrogen generation for steel decarbonization at pilot scale and establish a replicable framework for scaling up to industrial level. The research also establishes essential scaling parameters and economic thresholds for commercialization.
