フランスのRégiolis Hybridプロジェクトは、既存のバイモード車両の4基のパワーパックのうち2基を大容量リチウムイオン電池に置換し、回生ブレーキエネルギーを活用してエネルギー消費を20%削減することを目指した。旅客を乗せたLi-ion電池搭載列車として初めて6万km以上を走行し、台上試験でCO2最大25%減、HC52%減、NOx41%減等を確認。バイオ燃料性能と時刻表遵守・信頼性も評価した。
English
The Régiolis Hybrid project replaced two of four powerpacks in a dual-mode train with high-power Li-ion batteries to recover braking energy and cut consumption by 20%. The train carried passengers for the first time in France, logging over 60,000 km; bench tests replaying operational data showed up to −25% CO2, −52% HC, −41% NOx. Biofuel performance and timetable reliability were also assessed.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では鉄道の省エネ・脱炭素化はScope 3排出削減やグリーン輸送の文脈で注目される。特に非電化区間を持つ事業者にとって、既存車両の電池ハイブリッド化は設備更新コストを抑えた現実的選択肢となり得る。SSBJのScope 3開示やTCFD対応における運輸部門の削減実績としても参考になる。
In the global GX context
This paper provides rare real-world validation of battery-hybrid retrofits for rail, directly relevant to transport decarbonization pathways under ISSB/CSRD Scope 3 reporting. It demonstrates measurable CO2 and air pollutant reductions without compromising operational reliability, offering a template for fleet-level transition planning in the rail sector.
👥 読者別の含意
🔬研究者:Provides empirical data on hybrid train performance, energy savings, and reliability metrics for transport decarbonization modeling.
🏢実務担当者:Demonstrates a retrofit pathway for existing rolling stock to cut emissions and comply with Scope 3 targets without full fleet replacement.
🏛政策担当者:Offers evidence for supporting battery-hybrid retrofits as a cost-effective measure to meet transport decarbonization and air quality goals.
📄 Abstract（原文）
Abstract Régiolis Hybrid project involves modifying an existing dual-mode Régiolis train by replacing 2 of the 4 powerpacks with high-power lithium-ion batteries. The main aim of this project is to reduce energy consumption by 20% by recovering and exploiting electrical braking energy, previously dissipated as heat in the braking choppers. For the first time in France, a train equipped with Li-Ion batteries was able to carry passengers. Fitted with a datalogger that continuously sends all the necessary monitoring data, it then travelled more than 60,000 km, enabling a precise assessment of the overall performance. Environmental performance was measured by a test bench campaign to replay the data collected during commercial operation. This made it possible to assess the precise gain in CO2 emissions and pollutants without bias, and find up to −25% CO2, −52% HC, −41% CO, −41% NOx, −39% PM. Furthermore, performance with biofuels was also evaluated. Finally, reliability was studied from two angles: the ability to keep the timetable compared to the rest of the dual-mode trains fleet, but also by analyzing the new operating points of the remaining powerpacks to ensure that the usage profile doesn’t degrade the train reliability.
