インスタントコーヒー製造の脱炭素経路を技術経済的に評価した研究。バイオメタン・バイオマスへの燃料転換で最大86%削減しつつ経済性を維持でき、電化はエネルギー需要を6%削減し脱炭素電源下で最大72%減。水素は由来次第で排出量が大きく変動するが現状は高コストで、CCS併用時はネットマイナス排出も可能だがエネルギー需要とコストが増す。北欧はバイオメタン・電化、南欧は天然ガスが優位という地域差も示す。
English
A techno-economic assessment of decarbonization pathways for instant coffee manufacturing. Fuel switching to biomethane/biomass cuts emissions up to 86% while staying cost-competitive; electrification lowers energy demand 6% and emissions up to 72% with a clean grid. Hydrogen's footprint hinges on its origin and remains costly, while CCS with bioenergy can reach net-negative emissions at higher energy and cost. Regional differences favor biomethane/electrification in the Nordics and natural gas in Southern Europe.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
食品製造業のScope1排出削減はSSBJ・有報での気候関連開示やSBTi目標設定の実務課題であり、燃料転換・電化・CCSの費用対効果の比較は日本企業の脱炭素投資判断に示唆を与える。炭素価格や再エネ価格の感度分析は政策設計の参考になる。
In the global GX context
Provides sector-specific evidence on the cost-effectiveness of fuel switching, electrification, hydrogen and CCS for an energy-intensive food process—useful for transition-plan credibility under ISSB/CSRD and for Scope 1 abatement strategy in hard-to-electrify manufacturing.

📄 Abstract（原文）
Instant coffee (IC) manufacturing is among the most energy-intensive processes in the food and beverage industry, requiring substantial amounts of heat and electricity, and generating significant CO2 emissions. This study evaluates multiple decarbonization pathways—including fuel switching, process electrification, CO2 capture and storage (CCS), and energy efficiency—through a systematic techno-economic assessment. Results show that conventional natural gas-based (NG) production emits above 2.5 tCO2/tIC. Fuel switching towards biomethane and biomass results in CO2 emission reductions up to 86% while remaining economically competitive. Electrification reduces energy demand by 6% and can lower emissions by up to 72% with a decarbonized electricity grid. Similarly, the carbon footprint of hydrogen-based systems strongly depends on hydrogen origin: grey hydrogen emits about 3.5 tCO2/tIC, whereas green hydrogen can achieve reductions of 68–75% compared to ‘NG’. However, hydrogen remains prohibitively expensive under current market conditions. CC enables further reductions and even net-negative emissions (–0.2 to –2.88 tCO2/tIC) when combined with bioenergy, albeit with additional energy demand (+15–26% compared to NG) and higher costs. Regional analysis highlights stronger prospects for biomethane and electrification in Nordic countries, while NG-based systems remain economically favored in Southern Europe. The study emphasizes the importance of favorable energy prices, higher carbon pricing, sustainable biomass availability, electricity grid reinforcement, and waste heat recovery integration for the long-term decarbonization of the IC industry.
