Remora

What Remora does

Remora (legal entity Echeneidae Inc.) is a Detroit-area industrial technology company founded in 2020 that develops mobile carbon capture systems for diesel-powered heavy-duty vehicles, primarily locomotives and semi-trucks. Its core product is a zero-backpressure retrofit device that uses two proprietary adsorbents (engineered for humid exhaust conditions) and a proprietary gas separation process to extract and purify up to 90% of CO2 from exhaust, while reducing soot, particulate matter, and NOx to Tier 4 emissions standards. The modular architecture is designed to scale across vehicle types and is being extended to stationary applications such as ships, data center generators, cement kilns, and power plants.

The company's business model combines hardware sales with a recurring revenue component: Remora sells the capture system to operators, then the purified liquid CO2 is offloaded at rail yards and truck stops and sold to end users in food, beverage, agriculture, water treatment, manufacturing, and concrete industries, with revenue shared with the operator. Additional revenue streams include carbon removal/removal credit sales (with a signed offtake agreement with Shopify), and qualification for government incentives including 45Q ($60-$85/MT), EPA Emissions Reduction credits, and CARB Low Carbon Fuel Standard credits ($75-$125/MT). When paired with renewable diesel, the system enables carbon-negative operation via BECCS.

Remora operates a direct enterprise sales motion concentrated in North America (US and Canada), targeting Class I and short-line railroads and major fleet operators. Testing or development agreements are in place with Norfolk Southern, Union Pacific, Pacific Harbor Line (also an investor), and Genesee & Wyoming subsidiaries (BPRR, IORY), while trucking partners include Ryder, Werner Enterprises, Estes, Purolator, ForwardAir, and Covenant Logistics. The company has raised $117M in venture capital from a syndicate that includes Valor Equity Partners (lead), Lowercarbon Capital, Union Square Ventures, First Round Capital, Y Combinator, Neo, Voyager, and MCJ Collective, with Shopify and Pacific Harbor Line also participating as strategic investors.

Revenue model

1. Carbon Capture System Sales: Remora sells the carbon capture system to railroads and trucking companies. The system pays for itself over its lifetime and generates a return on investment for operators.
2. CO2 Revenue Sharing: Remora extracts and purifies up to 90% of CO2 from vehicle exhaust and sells the purified CO2 to end-users (food, beverage, agriculture, water treatment, manufacturing, concrete industries), sharing revenue with the railroad or trucking company operator.
3. Carbon Removal Credits: Remora can sell carbon reduction credits for capturing CO2 from trains or trucks. Retrofit on renewable diesel/biofuel can make vehicles carbon negative, generating additional carbon removal credit revenue. Already signed a credit offtake agreement with Shopify.
4. Government Tax Credits: Remora is working to qualify for 45Q Tax Credit ($85/MT for CO2 sequestration, $60/MT for utilization), EPA Emissions Reduction credits, and CARB Low Carbon Fuel Standard Credits ($75-$125/MT for sequestration).

Core offering

Remora designs, manufactures, and sells mobile carbon capture systems that retrofit diesel locomotives and semi-trucks to extract and purify up to 90% of CO2 from exhaust while reducing soot, particulate matter, and NOx to Tier 4 standards. The company sells the captured liquid CO2 to industrial end users in food, beverage, agriculture, water treatment, manufacturing, and concrete markets, sharing the CO2 revenue with the rail or trucking operator that hosts the system.

Product overview

Remora offers a single unified product: the Remora Carbon Capture System, a mobile carbon capture technology that retrofits diesel locomotives and semi-trucks. The system consists of proprietary adsorbents (Breakthrough Adsorbents) and a proprietary gas separation process achieving 90% capture efficiency. Remora sells the captured and purified CO₂ to end users in industries such as food, beverage, agriculture, water treatment, manufacturing, and concrete, sharing revenue with railroad and trucking company partners. The company is also developing CO₂ offloading infrastructure as an add-on component at fueling locations. Future applications under development include ships, data center generators, cement kilns, and power plants.

Products and services

• Remora Carbon Capture System A mobile carbon capture system that retrofits diesel locomotives and semi-trucks with zero-backpressure capture technology, extracting and purifying up to 90% of CO2 from exhaust while reducing soot, particulate matter, and NOx to Tier 4 emissions standards. The captured CO2 is condensed to liquid and sold to industrial end users, with revenue shared with the railroad or trucking operator hosting the system.
• Breakthrough Adsorbents Remora's two proprietary adsorbents engineered to function in the humid exhaust environment of diesel engines, where off-the-shelf carbon capture solvents fail because they are corrosive, volatile, and can release carcinogens when they degrade. Used as the capture medium inside the Remora Carbon Capture System.
• Proprietary Gas Separation Process A proprietary gas separation process that integrates with the Remora capture system to deliver 90% CO2 capture efficiency, third-party validated. The process is informed by proprietary simulation tools, machine learning, small-scale testing, and full-scale validation.
• CO2 Offloading Infrastructure Offload tanks installed at distribution centers, truck stops, and rail yards along freight corridors where captured liquid CO2 is rapidly pumped out of vehicles during refueling. The collected CO2 is picked up by distributors and transported to industrial end users for sale and use.

Broad incumbents

• CarbonCapture Inc. CarbonCapture Inc. develops carbon removal technology using direct air capture (DAC) at industrial scale. While not focused on mobile vehicle capture, it competes for the same carbon capture and removal credit dollars and investor capital within the climate-tech ecosystem.
• Heirloom Carbon Technologies: Heirloom uses limestone-based DAC technology to capture CO2 from the atmosphere and is a leading player in the carbon removal market. Comparable as a carbon removal credit competitor pursuing the same voluntary corporate offtake market (e.g., Shopify-style buyers).
• 1PointFive (Occidental): 1PointFive is building one of the world's largest DAC facilities (Stratos) using technology licensed from Carbon Engineering. Comparable as a large-scale carbon removal credit supplier competing for the same corporate offtake demand Remora is targeting with vehicle-based capture.
• Wabtec Corporation: Wabtec is a major rail equipment manufacturer providing locomotive technology, emissions control, and Tier 4 upgrade solutions. Comparable as a key rail-industry incumbent whose emissions-reduction product portfolio intersects with Remora's locomotive retrofit offering, and a potential strategic acquirer or competitor.
• Climeworks: Climeworks is a pioneer in commercial direct air capture, operating the world's largest DAC facilities. As a leading CDR credit producer, it competes with Remora in the voluntary carbon credit market where corporate buyers like Shopify allocate offtake dollars.

Emerging players

• C-Quest Capital: C-Quest Capital invests in and originates carbon credits from cookstove and other nature-based and technology-based projects. Comparable as a participant in the voluntary carbon credit market where Remora sells its carbon removal credits.
• Carbon Clean Solutions: Carbon Clean Solutions provides industrial-scale carbon capture technology for point-source emitters (refineries, cement, steel). Comparable as a competitor in the broader carbon capture equipment market, though focused on stationary industrial sources rather than mobile vehicle applications.
• Global Thermostat: Global Thermostat develops commercial direct air capture technology with a focus on lower-cost capture. Comparable as a carbon capture technology developer competing for the same industrial CO2 utilization and CDR credit revenue pools Remora targets.
• LanzaTech: LanzaTech uses carbon capture and gas fermentation to convert captured carbon into fuels and chemicals (carbon-to-value). Comparable as a competitor in the carbon-to-value space where Remora sells captured CO2 into industrial end-markets like fuels and chemicals.

Direct peers

• CarbonOrO: CarbonOrO is a Canadian carbon capture company developing mobile carbon capture technology for diesel vehicles (trucks and locomotives), directly competing with Remora's core product offering in the same target market of heavy-duty vehicle emissions.
