日本語
本稿は、WIG（地効飛行）貨物機AIRSHIPを、ターボプロップ機や短距離海上貨物船と比較し、200–400海里の航路で37–44%の燃料削減を実証。持続可能航空燃料（SAF）と組み合わせると、ライフサイクルGHGを最大80%削減し、約21gCO2/tkmと化石燃料短距離海上輸送に匹敵する。WIGは時間重視貨物の有力な補完手段となる。
English
This paper compares the AIRSHIP WIG cargo craft against a regional turboprop and short-sea coaster on 200–400 NM Baltic routes, showing 37–44% block fuel reduction vs. the turboprop. With SAF, lifecycle GHG reduction reaches 80%, yielding ~21 gCO2/tkm comparable to fossil-fuel short-sea shipping. WIG craft are a viable complement for time-sensitive cargo currently served by aviation.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では離島や東南アジアとの物流にWIG技術の導入可能性があるが、本論文は欧州海域のケーススタディであり、直接的な政策連動は限定的。ただし、脱炭素輸送モードの選択肢として示唆に富む。
In the global GX context
The paper provides empirical efficiency data for an emerging transport mode (WIG) that could complement maritime and aviation decarbonization globally. For TCFD/ISSB frameworks, it offers a technology pathway for Scope 1 and 3 emissions reduction in logistics. The Baltic route case is applicable to many coastal regions.
👥 読者別の含意
🔬研究者:Compare WIG efficiency against established modes; useful for transport decarbonization modeling.
🏢実務担当者:Consider WIG-SAF as a potential option for time-sensitive cargo with lower emissions.
🏛政策担当者:Evaluate regulatory support for WIG infrastructure and SAF blending mandates to accelerate adoption.
📄 Abstract（原文）
Global transport decarbonization requires solutions faster than shipping and lower-emission than aviation. This paper compares the AIRSHIP commercial concept — a 12–16-tonne autonomous WIG cargo craft — against the ATR-42-600 regional turboprop and a short-sea coaster across 200–400 NM Baltic and Northern European routes. The AIRSHIP achieves 37–44% lower block fuel consumption than the ATR-42-600 at equivalent ranges, covering a 200 NM route in 50 minutes versus 8–12 hours for a displacement vessel. Sustainable aviation fuel requires no propulsion or infrastructure modification while enabling up to 80% lifecycle GHG reduction, placing WIG-SAF operations at approximately 21 g CO 2 /tkm — comparable to short-sea shipping on fossil fuels. WIG craft are a viable complement to existing modes for time-sensitive cargo on routes where aviation is the current alternative.
