I appreciate the fish pun! This is why we're currently offloading the CO2 every 600 miles. Luckily, offloading only takes a couple mins, and drivers are legally mandated to stop every 8 hours (< 600 miles of driving), so they can just offload while they stop, or at the end of the day. 600 miles worth of driving creates about 1,800 lbs of CO2, which is very doable to store onboard a truck.

To offload, the driver attaches a hose, which connects to an offloading tank, and the CO2 is pumped from the tank inside our device to the much larger offloading tank. We liquefy the CO2 as it comes off the truck for storage in the tank. Luckily, the pump doesn't use much energy, and our early partners are using renewable energy to power the pump! We plan to continue using

Is this likely to go on container ships and help them become more eco friendly?
potentially yes that could be a market we expand to. We want to capture all the engine exhaust CO2 we can! So maybe trains as well.

There are different exhaust compositions for the engines on these different vehicles, in part because they use slightly different fuels. So there will be some research and work to do before jumping into the next market, but we love developing technology that has never existed before, we are so excited!!

Does the weight of the CO2 negatively impact the fuel efficiency of the truck in any appreciable way?
We think the impact to fuel efficiency will be < 3%, but we'll be doing more testing over the next couple months to get an exact figure. We'll capture those extra carbon emissions, and we'll more than pay for the extra fuel cost by sharing the revenue from selling the carbon dioxide.
