Remora Carbon

Onboard CO2 capture for heavy trucks

Overview

Remora Carbon provides a CO2 capture device for Class 8 tractors that attaches to the truck’s aftertreatment system to scrub exhaust and capture CO2, which is then compressed and stored in onboard tanks. The system uses exhaust heat to help power parts and can automatically bypass if tanks are full, allowing the truck to keep moving. Offloading is done by connecting to external tanks; Remora Carbon installs offload tanks at distribution centers for round trips and is rolling out tanks at truck stops for long-haul routes. Captured CO2 is delivered to end-users or sequestered underground in EPA-certified wells. Revenue comes from selling or leasing the devices and from collecting and delivering the captured CO2. The goal is to reduce carbon emissions in the trucking industry by providing a practical, scalable CO2 capture and storage solution.

Simplify's Take

What believers are saying

  • Pacific Harbor Line partnership deploys at Long Beach and Los Angeles ports in 2025.
  • Union Pacific and Norfolk Southern pilots enable scaling across major U.S. rail fleets.
  • Offload infrastructure at truck stops creates network effects boosting adoption speed.

What critics are saying

  • Declining CO2 prices from Climeworks crush revenue-sharing within 12-24 months.
  • Norfolk Southern abandons pilots due to 20% fuel penalty in 6-12 months.
  • Cummins launches cheaper integrated capture capturing 25% truck market in 18-24 months.

What makes Remora Carbon unique

  • Remora retrofits Class 8 trucks with zero-backpressure carbon capture achieving 90% CO2 efficiency.
  • Technology elevates locomotives to EPA Tier 4 standards via exhaust scrubbing without retrofits.
  • Revenue-sharing from selling captured CO2 to agriculture and manufacturing distinguishes model.

Pacific Harbor Line Expands Sustainability Efforts with Remora Partnership

Pacific Harbor Line expands sustainability efforts with Remora partnership. Anacostia Rail Holdings (ARH) announced that its Pacific Harbor Line (PHL) subsidiary has entered into a development agreement with Remora, a Michigan-based climate technology startup that is pioneering mobile carbon capture for freight rail and trucking. PHL, which provides rail transportation, maintenance and dispatching services to both Ports of Long Beach and Los Angeles, is also an investor in Remora, and Peter A. Gilbertson, president and CEO of PHL's parent company, Anacostia Rail Holdings, serves as an advisor. The partnership aligns with PHL's long-standing commitment to innovation, environmental stewardship, and practical pathways toward decarbonization of freight rail operations. "We are proud of our progress toward zero emission operations, which started when we acquired Tier 2 (lower emission) locomotives some 16 years ago," says Otis L. Cliatt II, PHL President. That initial success was followed by an evolution to Tier 3+ locomotives and then a conversion to renewable diesel fuel which cut CO[2] emissions by some 70 percent. PHL also operated a zeroemission (ZE) EMD(R) Joule battery-electric locomotive from Progress Rail in test service, and it currently operates a Tier 4 locomotive. The railroad plans to upgrade its entire fleet of Tier 3+ locomotives to Tier 4 using proven after-treatment technologies. "For PHL and Anacostia, carbon capture adds yet another option in our efforts to slash emissions," says Gilbertson. "In addition to reducing CO[2] emissions, Remora's technology elevates connected locomotives to EPA Tier 4 standards and also enables the reuse of carbon in other commercial applications." The U.S. is facing a CO[2] shortage, even as trains and trucks emit roughly 375 million tons of it every year. Remora's solution captures that CO[2], converts it to liquid, and sells it to industries such as farming, food production, and manufacturing, sharing the revenue with its transportation partners. "This partnership with Remora gives PHL an opportunity to help shape a technology that could significantly reduce freight rail emissions while creating new economic value for operators," said Cliatt. "We're proud to support innovations that have the potential to benefit the entire rail industry." Founded five years ago, Remora has raised $117 million in venture capital from investors. The company's early truck-based pilots informed a redesigned system that eliminates backpressure, increases efficiency, and captures up to one ton of CO[2] per hour at locomotive scale. "We're building this technology not only to meet environmental goals, but to make it financially compelling for railroads," said Paul Gross, co-founder and CEO of Remora. "Pacific Harbor Line's support and Anacostia's leadership will be instrumental as we bring carbon capture to freight rail."
