📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では水素社会実現に向けた動きが活発であり、既存の天然ガスインフラを活用したハイスン導入は、商用車・物流分野の脱炭素化に寄与する可能性がある。また、SSBJ開示やカーボンプライシングへの対応として、実効性のある移行技術のエビデンスとして有用。
In the global GX context
Globally, this study provides empirical evidence for hythane as a bridge technology in heavy-duty transport, aligning with EU post-2030 CO2 and Euro 7 targets. It supports transition finance and disclosure frameworks by demonstrating a practical, low-disruption decarbonization option.

📄 Abstract（原文）
Engines remain central to the heavy-duty transport sector, yet meeting Europe's post-2030 CO₂ and Euro 7 emission targets requires low-disruption, rapidly deployable strategies. Natural gas infrastructure is already established in many regions, and hydrogen blending offers a route to reduce fuel carbon intensity without major hardware changes. This study evaluates methane and Hythane (methane with 20% H₂) fueling in a spark-ignition engine, supported by validated Chemkin-Pro simulations incorporating 20% exhaust gas recirculation (EGR). Experimental measurements characterized performance and emissions across loads, fuel blends and equivalence ratio (lambda, λ), while the simulation framework quantified λ- and EGR-dependent NOx formation using a global EGR-species formulation. Relative to neat methane, Hythane reduced ignition delay, improved combustion completeness, and extended the lean stability limit, without increasing cylinder pressure, confirming compatibility with hardware. With 20% EGR operation at λ ≈ 1.25 can achieve <0.2 g/kWh NOx (with aftertreatment), <0.8 g/kWh unburnt hydrocarbons, and over 30% CO₂ reduction relative to a Euro 6 diesel. These results provide new evidence that Hythane fueling, combined with existing EGR and aftertreatment systems, offers a practical, resource-efficient and minimally disruptive pathway for current gas engines to meet future emissions targets, supporting fleet decarbonization and air-quality goals.
