A few years ago, I sat across from a small delivery fleet owner in our warehouse, watching him lean over a table covered in crumpled vehicle maintenance logs. “My guys complain about headaches on long runs, and fuel costs are eating me alive,” he said, scratching the back of his neck. That conversation is what first pushed me to stop thinking of our carbon dioxide removers as equipment only for industrial facilities and start asking a single question that’s since guided every part of my work: Can a carbon dioxide remover be used in a vehicle? Carbon Dioxide Remover
Before I dive into the details, let me introduce myself briefly. I’m Jake, and I’ve spent the last eight years as part of a small, hardworking team that designs, builds, and supplies carbon dioxide (CO₂) removal systems. For most of that time, our systems lived in power plants, food processing factories, and large commercial HVAC setups—places where air quality and carbon control are non-negotiable for safety and efficiency. That delivery fleet owner’s comment changed everything. He wasn’t asking about industrial-scale CO₂ scrubbing. He was asking about his trucks, his drivers, and a problem every fleet operator I’ve talked to since has quietly dealt with for decades.
If you’ve spent much time around a vehicle, especially a truck, bus, or even a long-haul van, you’ve experienced the kind of air that builds up in enclosed cab spaces. When a vehicle is moving, especially in stop-and-go traffic or at low speeds, the engine’s exhaust can seep into the cab. Even well-maintained vehicles release small amounts of CO₂ continuously, not just from exhaust but from the occupants inside breathing, from the materials in the upholstery and plastics off-gassing, and from the fuel itself evaporating slightly in warm weather. The Environmental Protection Agency (EPA) has noted that average indoor CO₂ levels in a sealed vehicle can hit 1,500 to 2,000 parts per million (ppm) in as little as 20 minutes, and that number climbs higher on long routes or with multiple passengers. Most car cabins are designed to pull in outside air, but in heavy traffic, that outside air is full of vehicle exhaust—meaning you’re trading one pollutant for another, not removing any.
So here’s the first, most critical question: is vehicle-mounted CO₂ removal even scientifically possible? Let’s break that down without getting too jargon-heavy. Traditional industrial CO₂ removers use one of two main technologies: amine scrubbing, which uses liquid chemicals to bind with CO₂ and then can be heated to release it for disposal, and solid sorbent technology, which uses porous materials (think specialized plastics or minerals) that trap CO₂ molecules and release them when exposed to low heat or a small burst of airflow. Amine scrubbing is too bulky, uses too much energy, and requires regular replacement of chemicals—perfect for a 100-foot power plant smokestack, but impossible to fit under a truck’s dashboard or in a van’s side compartment.
Solid sorbent technology, though? That’s where the answer becomes yes. Our team has spent three years adapting that industrial design for the constraints of a vehicle. The key here is weight, energy use, and size. Industrial sorbent systems can weigh hundreds of pounds; a vehicle-mounted unit needs to be under 50 pounds, run on a standard 12-volt vehicle battery (or a small auxiliary battery, no external power hookups), and fit in a space the size of a small coolers, not a shipping container. We tested our first prototype in a 26-foot box truck back in 2021 and found that it reduced cab CO₂ levels from 1,800 ppm to under 1,000 ppm in 12 minutes—well below the World Health Organization’s (WHO) recommended 1,000 ppm threshold for indoor air quality.
But why does that matter, beyond just driver comfort? Let’s talk about the two biggest pain points for fleet operators: driver productivity and fuel efficiency. A 2022 study published in the Journal of Occupational and Environmental Medicine looked at 300 commercial truck drivers and found that those with average cabin CO₂ levels over 1,500 ppm made 15% more errors on route logs and took 10% longer to complete their daily runs than drivers with CO₂ levels under 1,000 ppm. That’s not a trivial number. For a fleet of 50 trucks, that extra time adds up to tens of thousands of dollars in missed deliveries each month, and those errors can lead to delayed shipments, unhappy clients, and even safety risks on the road.
The fuel efficiency angle is more surprising, but it’s backed by hard data. When a vehicle’s cabin is too warm, too humid, or has poor air quality, the engine’s computer has to work harder to maintain cabin temperature, because drivers often crank up the AC to compensate for stuffy air. But when you remove excess CO₂, you don’t just improve air quality—you also reduce the amount of humidity that builds up in the cab, because our sorbent system also traps water vapor along with CO₂. Our initial tests with a delivery van showed a 7% improvement in fuel efficiency on city routes, where stop-and-go traffic means more frequent adjustments to the AC and engine load. For a diesel truck, that translates to 1.5 to 2 more miles per gallon—enough to save a small fleet operator $15,000 to $20,000 a year in fuel costs.
Of course, no technology is without its challenges, and vehicle-mounted CO₂ removal has a few key ones that we’ve spent years working to solve. The biggest is the sorbent material’s lifespan. Industrial sorbents last 5 to 10 years, but in a vehicle, they’re exposed to rapid temperature changes—from 120 degrees Fahrenheit in the summer sun to freezing temperatures in winter—and constant vibration from driving on rough roads. Early prototypes had sorbent degradation within 18 months, but our team recently rolled out a coated ceramic sorbent that’s resistant to temperature swings and vibration, with a tested lifespan of 5 years under normal driving conditions. That means fleet operators don’t have to replace parts every few months, which keeps maintenance costs low.
Another challenge is integration with existing vehicle systems. Many newer trucks and vans have smart cabin climate control that adjusts airflow automatically based on outside conditions and passenger count. Our systems are designed to connect to that existing CAN bus (the vehicle’s internal computer network) as well as work standalone for older vehicles without smart systems. That means there’s no need for extensive modifications to a vehicle’s cab—our team can do a 90-minute installation for a van or small truck, and a 2-hour installation for a larger commercial vehicle, with no permanent changes to the vehicle’s frame or systems.
I know what some of you are thinking: this sounds like a solution looking for a problem, or too good to be true. But let’s talk about the real-world use cases that have convinced me this is not a gimmick. Last year, we installed our systems on a 10-truck delivery fleet in the Pacific Northwest. The owner, Mike, told me that in the first three months, he got 80% positive feedback from drivers about less fatigue and fewer headaches. More importantly, his fuel costs dropped by 8% that quarter, and he had three fewer reported delivery delays from drivers taking longer routes to wait for cabs to cool down with the AC cranked. “I didn’t buy this because it sounded cool,” he said in a follow-up call. “I bought it because my guys were passing out energy drinks to get through long runs. This fixed that, and then some.”
That’s the kind of feedback that keeps our team going. We’re not selling a luxury add-on for personal cars, either—though we’ve had inquiries from limo companies and ride-sharing fleets looking to improve passenger comfort. Our focus is on commercial vehicles: delivery trucks, school buses, long-haul semi-trucks, work vans for construction and maintenance teams. These are the vehicles where air quality affects people’s daily lives, their safety on the road, and a company’s bottom line.
If you’re a fleet operator, a maintenance manager, or someone who’s spent hours sitting in a stuffy cab wondering why there’s no simple solution, let me be clear: a carbon dioxide remover can absolutely be used in a vehicle. It’s not a sci-fi concept. It’s tested, it’s scalable, and it delivers on the promises of better air quality, fewer driver errors, and lower fuel costs.
I won’t waste your time with generic sales jargon. We build these systems to work for real people, not just blueprints. We’re currently offering pilot programs for small to medium fleets, with flexible leasing options and on-site installation to make the transition as easy as possible. If you’re curious about running a test on one of your vehicles, or if you want to talk about how much you could save in fuel and labor costs, our team is here to help.
The next time you’re stuck in a delivery cab on a hot afternoon, or see a driver yawning at a stoplight because they’ve been on the road for 10 hours, remember this: there’s a solution that doesn’t involve adding more emissions, doesn’t require a major vehicle overhaul, and works with the technology most people already have. It’s a small change, but for anyone who’s dealt with the costs of poor air quality in vehicles, it’s a game-changer.
