從排氣管開始的減碳革命：Remora 如何重塑交通運輸的 ESG 策略

當全球交通運輸部門持續面對減碳壓力，密西根州的新創公司 Remora 提出了一項大膽又實用的解方——將碳捕捉設備直接安裝在柴油車與火車上，於源頭即時抽取排放的二氧化碳（CO₂）。這不僅開啟了移動式碳捕捉（Mobile Carbon Capture, MCC）的新篇章，也為高排放的貨運行業帶來迫切需要的轉型契機。

Decarbonizing on the Move: How Remora’s Mobile Carbon Capture Technology is Redefining Transportation ESG

As the global transportation sector faces mounting pressure to decarbonize, Michigan-based startup Remora has introduced a bold and pragmatic solution - installing carbon capture devices directly onto diesel trucks and trains to extract carbon dioxide (CO₂) emissions at the source. This initiative not only opens a new chapter in Mobile Carbon Capture (MCC) but also provides a timely transformation pathway for the freight industry, one of the hardest sectors to decarbonize.

ESG 策略中的「技術創新」：用硬體解決排放難題

與多數以數據與管理為主的 ESG 解方不同，Remora 將 ESG 融入硬體創新，研發一套可裝載於現有柴油貨車與火車的碳捕捉系統。其最新版本預計每小時可捕獲約一公噸 CO₂，並轉為液態銷售予農業、食品與飲料等行業使用，實現「碳變資產」（carbon-to-value）的商業模式。

Tech Innovation as ESG Strategy: Hardware for a High-Emission Problem

Unlike most ESG solutions centered around data and management, Remora integrates ESG through hardware innovation, developing a retrofit carbon capture system compatible with existing diesel trucks and locomotives. Its latest model is designed to capture up to one metric ton of CO₂ per hour, converting it into liquid form for resale to sectors like agriculture, food, and beverages - realizing a “carbon-to-value” business model.

目前，公司已獲得 1.17 億美元創投資金支持，並已投入超過五年進行研發與迭代。這項技術的最大亮點是：無需更換車輛、即可減碳，降低傳統運輸業的轉型門檻。

從失敗中學習：2023 年實測經驗如何推進技術升級？

The company has secured $117 million in venture capital and has invested over five years in R&D and iteration. The standout feature: decarbonization without replacing the vehicle fleet, significantly lowering the barrier to transition for traditional transport operators.

儘管 Remora 在 2023 年的首次試點中，遭遇如排氣水淹與引擎回壓等挑戰，導致原始設計無法穩定運作，但這些挫折反而促使團隊進一步升級其材料與結構。

最新系統採用全新吸附材料，可有效濾除碳黑與粉塵，同時將 CO₂ 捕捉效率提升至 90%。並計劃於 2026 年正式在移動列車上進行實測，進一步驗證技術成熟度。

氣候治理從引擎開始：大型運輸企業與鐵道巨頭的 ESG 承諾

包括 Union Pacific、Norfolk Southern、DHL、Ryder 等多家重量級物流與運輸企業，皆參與 Remora 系統的試驗。這顯示，即便在 ESG 政策受到川普政府影響而受限的美國環境下，產業領導者仍選擇積極布局長期減碳目標。

Learning from Setbacks: How 2023 Trials Advanced the Tech

Although Remora faced challenges in its 2023 pilot - such as exhaust condensation flooding and engine backpressure that hindered initial system stability - these setbacks became catalysts for technological advancement.

The latest version employs new sorbent materials capable of filtering out carbon black and particulates, and has boosted CO₂ capture efficiency to 90%. A field test on mobile locomotives is scheduled for 2026, aiming to validate the technology's readiness at scale.

Climate Governance Starts with Engines: Transport Giants Align ESG with Operations

Major logistics and transport companies, including Union Pacific, Norfolk Southern, DHL, and Ryder, have joined Remora’s trials - signaling that even in the regulatory uncertainty of a post-Trump U.S. ESG landscape, industry leaders are still committing to long-term carbon reduction goals.

對鐵道業而言，Remora 的系統具有獨特吸引力，能套用於既有柴油機車，減少因更新車輛而產生的碳足跡與資本支出，並將永續納入資產管理與折舊週期中。

移動碳捕捉的潛力與挑戰：一場關於「可攜式永續」的實驗

移動式碳捕捉雖具有龐大潛力，但其挑戰亦不容忽視。CO₂ 的密度與重量意味著高昂的運輸成本，同時如何在不影響車輛效能下高效抽取並儲存廢氣，也考驗工程設計極限。

然而，若 Remora 能成功完成實測並進入規模化部署階段，此技術將為交通運輸領域提供一條少有的「不必汰換車隊也能減碳」路徑，也將在全球氣候技術投資市場中占有一席之地。

For the rail sector, Remora's system offers unique appeal: it can be retrofitted to existing diesel locomotives, reducing both the carbon footprint and capital expenditure associated with fleet replacement. It also enables sustainability integration into asset management and depreciation cycles.

The Promise and Pitfalls of Mobile Carbon Capture: A Test of Portable Sustainability

While the promise of MCC is substantial, the challenges are equally real. The density and weight of captured CO₂ result in high transport costs, and the need to efficiently extract and store exhaust gases without compromising vehicle performance pushes engineering limits.

However, if Remora successfully completes testing and scales up deployment, this technology could offer the rare decarbonization path that doesn’t require fleet turnover, securing its place in the global climate tech investment landscape.

重塑 ESG 框架下的運輸正義與技術平權

Toward Transport Justice and Tech Equity in ESG

值得注意的是，Remora 的技術不只是企業減碳策略的補強工具，也可能成為 氣候正義（climate justice）的一環。對於難以負擔電動車或氫能轉型的中小型物流商而言，碳捕捉 retrofit 技術提供了具備即時性與成本效益的減碳管道，實現技術平權與多元路徑減碳的 ESG 原則。

Importantly, Remora’s innovation is more than a corporate carbon reduction tool - it may also become a vehicle for climate justice. For small and medium-sized logistics companies unable to afford a transition to electric or hydrogen fleets, retrofit carbon capture provides an immediate and cost-effective decarbonization solution, advancing both technological equity and the multi-pathway principle of ESG.

在 ESG 的未來，解方不再是二選一，而是科技、政策與市場的多點佈局。Remora 的案例提醒我們，即使來自排氣管的微小變化，也能為重型交通的低碳轉型，打開一扇新門。

In the future of ESG, solutions are no longer binary - they’re multi-faceted, shaped by technology, policy, and market dynamics. Remora’s case reminds us that even small changes from a tailpipe can open a new door to low-carbon transformation in heavy transport.
