Totally. Definitely could be cool to explore down the line.

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 fue

1. The regeneration process actually requires very little energy because we're able to use waste heat from the truck's exhaust to power the process. 2. The tank requires 8 ft x 8 ft (on a 16 ft x 16 ft pad). The pump and refrigera

Absolutely. One of our first pilot offloading stations is actually about 6 miles from a concrete producer. The other piece is that we'll add our technology to the tanker trucks that are transporting the CO2. It'll take us a few mo

We haven't explored that, but carbon capture technology would work for residential chimneys. The challenge would be figuring out how to pick up the captured CO2 from so many different locations. One of the reason we're initially t

Lowercarbon Capital is amazing! You should definitely drop them a line.

There are 230 million tons of demand for CO2 worldwide every year, and all the semi trucks in the US produce 340 million tons of CO2. Medium term, though, we're actually planning to start sequestering the CO2 deep underground in deplet

Exactly. The challenge with hydrogen that we've seen is that it's extremely flammable (even when mixed with a small amount of air) so it requires thousands of pounds of reinforcement to make it safe to carry on a truck, which dram

The device does not affect the aerodynamics of the truck or the power of the truck. It creates essentially no back pressure on the engine. In our beta testing, our device currently increases back pressure < 0.5 psi, which is nearly negli

Exactly. We still need to do more dyno testing to get an exact figure, but we think the impact to fuel efficiency will be < 3%. We'll capture those extra carbon emissions, and we'll more than pay for the extra fuel cost by shar

Yes, that's exactly the proposal!

This is a crucial question! To our surprise, our beta testing of our prototype has actually shown that this is creating < 0.5 psi back pressure on the engine (negligible) and we believe we can get it down to essentially 0 by the time we

Agreed. The concrete producers inject it into their concrete, which is widely thought to be one of the most permanent forms of CO2 storage in existence. We will only work with end users that are using the CO2 in a way that permanently takes

Thanks so much for the interest! Feel free to email us at hello@remoracarbon.com.

Exactly. We want this to be as simple as possible for folks to add to their existing trucks, so it's easiest for us to store the captured CO2 inside our device on the back of the cab.

Right now, we're probably at around 60-70% lifetime reduction (we're doing a comprehensive lifecycle analysis during our first pilots this summer). Over time, as the capture rate of our device approaches 100%, we think we can get

We've definitely got a lot of work to do to prove that this solution can truly be carbon negative (we're actually partnering with the University of Michigan to test this over the next couple months), but many scientists agree that

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 ju

We're starting with large companies that own their own fleets and have made aggressive climate commitments. We share the revenue from the carbon dioxide with them, so they have two incentives to install these devices: meet their climat

Our adsorbent actually captures the CO, NOx, and SOx in vehicle exhaust, so we'll be taking those out of the air in addition to CO2! Any particulate matter that makes it through the diesel particulate filter will cake onto our adsorben
