Imagine a school science fair project where kids build a device to capture smoke from a toy truck’s exhaust, filter it, and then show how it could be reused.

Now, picture this on a much larger scale with real semi-trucks, and you’ve got Remora’s technology.

Remora is a Detroit-based startup developing a device that captures carbon emissions directly from the tailpipes of semi-trucks.

Their solution helps reduce the environmental impact of heavy-duty transportation while creating a new revenue stream for truck owners.

The Beginning of Remora

Remora's journey began in 2020 when Paul Gross, inspired by his solo bicycle trip across the US and a passion for carbon-neutral transportation, co-founded the company.

The idea was to capture carbon emissions from semi-trucks, repurpose the captured carbon, and reduce the environmental impact of heavy-duty transportation.

How Remora Captures Carbon Emissions

Remora's device bolts onto the back of a Class 8 tractor, attaches to its tailpipe, and filters carbon emissions using carbon scrubbing technology.

The captured CO2 is compressed and stored in onboard tanks. Drivers can offload it during refueling stops, allowing the trucks to continue their journeys without interruption.

The captured CO2 can then be sold to end-users or sequestered permanently in EPA-certified wells, creating revenue for truck owners.

A Retrofit Approach to Carbon Capture

Remora's approach to carbon capture uses a device that can be retrofitted onto existing trucks.

Electric semi-trucks face challenges related to heavy batteries and limited range. Remora's device can be retrofitted onto existing trucks, making it adaptable and cost-effective.

The captured CO2 can also be converted back into diesel using CO2-to-fuels technology. This creates a circular economy that leverages existing infrastructure without the need for massive overhauls.

Remora's Funding

In February 2024, Remora secured Series A funding from Voyager Ventures.

This followed a seed funding round in April 2021, when the company attracted investment from First Round Capital and other investors.

Such financial backing underscores the potential impact of Remora's technology on the global effort to combat climate change. (Source: Crunchbase)

Remora's Vision and Values

Remora's vision emphasizes urgency, honesty, and respect for its team and partners.

The company focuses on developing a solution that addresses the climate crisis while making operational and financial sense.

Remora describes its approach as low-ego and high-intensity, with a focus on its mission.

Carbon-Negative Trucks

Remora's technology has the potential to make semi-trucks carbon-negative, especially when paired with biofuels.

In this model, the more these trucks are driven, the more CO2 is removed from the atmosphere.

The approach is cheaper and more effective than other carbon removal methods, thanks to the higher concentration of CO2 in vehicle exhaust compared with ambient air.

Turning Emissions into Revenue

Remora's device captures carbon emissions from semi-trucks, stores the CO2 onboard, and creates revenue options through selling or permanently sequestering it.

By turning carbon emissions into an opportunity for truck owners, Remora supports the environment and businesses that rely on heavy-duty trucking.

Remora is capturing the future one truck at a time.
