この研究は、LNG燃料船におけるオンボード炭素回収（OCC）の温室効果ガス削減効果と副作用をライフサイクル評価で分析。2隻の船（大型クレーン船SleipnirとLNG運搬船）を対象に、32-55%のGHG削減が可能であることを示し、非気候影響は限定的だが燃料供給やメタンスリップの影響を考慮したケースバイケースの評価を推奨している。
English
This study uses Life Cycle Assessment to evaluate greenhouse gas (GHG) mitigation and side-effects of on-board carbon capture (OCC) on two LNG-fueled ships (crane ship Sleipnir and an LNG carrier). Results show a 32–55% GHG reduction potential, with manageable non-climate impacts. The study recommends including OCC in the portfolio of intermediate decarbonization options for the maritime sector, emphasizing case-by-case evaluation of life cycle emissions.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
本論文は、国際海運の脱炭素化（IMO目標）に関連し、日本の海運・造船業界がLNG燃料船へのCCUS導入を検討する際の定量的根拠を提供する。特に、メタンスリップや燃料供給チェーンを含むライフサイクル視点の重要性を強調しており、SSBJに基づくGHG排出開示の精緻化にも示唆を与える。
In the global GX context
In the global context, this paper supports the IMO's 2050 decarbonization targets by demonstrating the viability of on-board carbon capture as an intermediate solution alongside alternative fuels. It highlights the need for life-cycle-based assessment in climate disclosure frameworks like the ISSB's marine fuel standards.

📄 Abstract（原文）
Decarbonization targets for the maritime sector until 2050 require greenhouse gas (GHG) mitigation options like alternative fuels and on-board carbon capture (OCC). This study assesses GHG mitigation and side-effects of OCC via Life Cycle Assessment of two LNG-fueled ships, the large crane ship Sleipnir and an LNG carrier, and their distinct operational profiles. A large bandwidth of 32%–55% GHG emissions mitigation is achievable, depending on the ship, operation and design. Non-Climate impacts increase without raising major environmental concerns for the monoethanolamine-solvent OCC systems, based on the measured emissions from pilot operation, despite the limited applicability of current impact pathway modelling on open-sea context. With lower GHG mitigation potential compared to alternative fuels but potentially better availability due to less competition from other sectors, including OCC into the portfolio of intermediate decarbonization options for the marine sector is recommended, emphasizing case-by-case evaluation of life cycle emissions, especially fuel supply and methane slip affected by the operational profile.
