本研究は、ディーゼル式冷凍コンテナ（MRC）とリチウムバッテリー式冷凍コンテナ（LRC）のライフサイクルGHG排出量を比較した。中国のグリッドベースでは両者の排出量はほぼ同等だが、クリーンな電力や低排出バッテリー生産、低GWP冷媒などの条件下でLRCが有利となる。運行段階が排出量の約95%を占め、牽引用エネルギーの影響が大きい。
English
This study conducts a life cycle assessment (LCA) of diesel mechanical vs. lithium battery refrigerated containers (40-ft). Under a China baseline grid, total GHG emissions are nearly equal (60.97 vs 61.04 g CO2e/t-km). Battery containers become favorable with cleaner electricity, lower-emission battery production, and low-GWP refrigerants. Operational phase dominates (95% of lifecycle GHGs), driven by traction energy. The results highlight the conditions under which electrification of refrigeration yields GHG reductions.

📄 Abstract（原文）
Abstract Decarbonizing temperature-controlled road freight is essential to sustainable food systems but complicated by the added energy demand of refrigeration. We perform a cradle-to-grave life cycle assessment (LCA) of 40—ft refrigerated containers comparing a diesel mechanical refrigerated container (MRC) with a battery-driven lithium refrigerated container (LRC). This study focuses on climate change impacts expressed as life cycle greenhouse gas (GHG) emissions (CO₂-equivalent). Under a China grid baseline, life-cycle GHG emissions are effectively equal: 60.97 vs 61.04 g CO₂e/(t·km) for MRC and LRC, respectively—a marginal + 0.12% for LRC. Operation dominates (~ 95% of life-cycle GHGs), led by traction energy. Although electrifying the refrigeration unit lowers use-phase emissions, gains are offset by ( i ) the mass penalty of the battery pack, which raises traction energy, and ( ii ) upstream emissions from battery manufacturing on a carbon-intensive grid. Sensitivity analyses show LRC becomes favorable with cleaner electricity, lower-emission battery production and recycling, low-GWP/low-leakage refrigerants, and reduced empty running. Conversely, when grid carbon intensity is high, electrifying refrigeration alone yields negligible benefit. Larger near-term mitigation likely comes from electrifying vehicle drive, power-system decarbonization, and logistics optimization. Additionally, although the LRC entails a modestly higher upfront investment, its lower operational energy demand translates into improved life-cycle economic performance. These results provide a transparent baseline for comparing lithium-battery and mechanical refrigeration pathways and clarify the grid, mass, and refrigerant conditions under which refrigeration electrification delivers measurable GHG reductions. The future research could extend this framework by incorporating non-CO₂ climate forcers, air pollutant emissions, and broader material-related environmental impacts to enable a more comprehensive sustainability assessment.
