水素、太陽熱、バイオエネルギー、CO2変換技術を統一した技術経済指標で比較評価した研究。水素は66〜95%の温暖化削減と10.0〜15.7兆ドルの緩和コスト削減をもたらす一方、2030年までに600MtのCCUS容量ギャップがある。電化40%、CCUS30%、循環経済16%を組み合わせたセクター横断統合枠組みを提示し、企業のサステナビリティ計画やインフラ投資判断に定量的示唆を与える。

English

This paper provides a cross-technology quantitative assessment of hydrogen, solar thermal, bioenergy, and CO2 conversion, using unified techno-economic metrics. Hydrogen offers 66–95% global warming reduction and $10.0–15.7 trillion in mitigation cost savings, but a 600 Mt annual CCUS capacity gap remains by 2030. A cross-sector framework links electrification (40%), CCUS (30%), and circular economy (16%) for hard-to-abate industries, offering actionable insights for corporate planning and infrastructure investment.

📄 Abstract（原文）

Energy conversion technologies are fundamental to decarbonizing global energy systems, yet their widespread adoption is hindered by high costs, infrastructure gaps, and poor cross‐sector integration. This paper provides a novel cross‐technology comparative framework through an integrated quantitative assessment of hydrogen production, solar thermal systems, bioenergy, and CO 2 conversion technologies, evaluating their technical readiness, scalability, and system integration potential using unified techno‐economic metrics and a cross‐sectoral framework. The analysis reveals that hydrogen offers 66–95% global warming reduction potential and $10.0–15.7 trillion USD in climate mitigation cost savings, alongside a 600 Mt. annual CCUS capacity gap by 2030. While several conversion technologies have reached technical maturity (TRL 7–9), realizing chemical‐sector CCU potential would require over 18,100 PWh (55% of projected global supply) of low‐carbon electricity. A cross sector integration framework links electrification (40%‐), CCUS (30%, 1.49 Gt CO 2 /yr), and circular economy strategies (16%) for hard‐to‐abate industries. The findings provide actionable quantitative insights for corporate sustainability planning, R&D portfolio optimization, and infrastructure investment decisions, emphasizing that widespread deployment depends on continued cost reductions, successful pilot to commercial scaling, and strategic modernization of energy infrastructure to achieve net zero emissions by mid‐century. The overarching objective is to guide strategic decision‐making for net‐zero transitions by providing a unified evidence base for prioritizing investments across competing technology pathways.
