The video introduces Remora, a pioneering company that has developed the world’s first commercial mobile carbon capture system designed specifically for diesel trucks and freight trains. Founded by Paul Gross, Remora retrofits vehicles with technology that extracts and purifies CO2 directly from their exhaust. This captured CO2 is then stored in pressure vessels and transported to end users such as food and beverage companies, greenhouses, and water treatment facilities, where it can be recycled in innovative ways. The system not only reduces emissions by up to 90% but also creates new revenue streams for transportation operators, addressing a significant source of carbon emissions in the US.
Paul Gross shares the origin story of Remora, explaining how he identified a CO2 shortage in the US despite massive emissions from transportation. Without a formal science or engineering background, he collaborated with experts, including Christina Reynolds, to develop the technology. He emphasizes that founders don’t need to be experts themselves but should build strong teams of specialists and continuously learn. The company’s approach focuses on point source carbon capture—extracting CO2 directly from exhaust rather than from the atmosphere, which is more energy-intensive and costly. Remora’s technology uses pellets that trap CO2 molecules from exhaust gases, allowing clean gases to pass through.
Remora’s innovation lies in its mobile, modular design, which can be installed on semi-trucks and locomotives. The company manufactures much of its hardware in-house near Detroit to leverage local engineering talent experienced in rugged, industrial applications. They have developed a simulator with a real truck engine in a shipping container to test and optimize their system under various conditions. This iterative process has improved the device’s efficiency, size, and CO2 capture purity. Remora is also developing a version for freight trains, including a dedicated rail car that processes exhaust on board, with a 4,400-horsepower locomotive serving as a test platform.
Scaling production presents challenges, particularly in creating modular kits that fit different vehicle models and maintaining vertical integration to speed up manufacturing and iteration. Remora currently employs 43 people and has raised $17 million in venture funding. They have signed evaluation agreements with major freight companies like Ryder and Union Pacific, signaling strong industry interest. The company’s goal is ambitious: to capture up to a billion tons of CO2 annually by expanding their technology to other sectors such as generators, oil and gas production, container ships, cement plants, refineries, and natural gas turbines.
In summary, Remora is tackling one of the hardest climate problems—transportation emissions—by innovating mobile carbon capture technology that is scalable and commercially viable. Their approach combines scientific rigor, engineering expertise, and strategic manufacturing to create a product that can dramatically reduce emissions from some of the most challenging sources to electrify. With strong backing and partnerships, Remora aims to make a significant impact on national and global carbon emissions, demonstrating the potential for carbon capture to be integrated into everyday industrial processes and transportation.
