This is an interesting idea - great to see people trying out new innovative ideas. I would have a couple questions:
1. How much energy is required to extract and regenerated the adsorbent?
2. How much energy to store CO2 and how much space on-site?
(First two questions are trying to discern if it is truly a net negative product or if the remainder of the process diminish the carbon balance significantly)
3. How much are you anticipating selling CO2 and what is the level of purity (we use it for one of input gases at our company)?
4. What is the reload time for the trucks CO2 wise - and how much of an operational hurdle is the implementation/execution? Truck fleets are notorious for not wanting to change their systems, especially for new untested tech. (It is a thin margin business - risk tolerance is low)
5. Unfortunately you can't claim CO2 credits unless you sequester the CO2 - however selling to cement or other industrials you can lower their carbon abatement costs! Therefore for pricing you would price above typically CO2, but low enough that you are saving them abatement costs.

The tank requires 8 ft x 8 ft (on a 16 ft x 16 ft pad). The pump and refrigeration unit are small and are mostly off, so they don't use a lot of energy. Our early partners are also powering them using renewable energy, to further help our lifecycle emissions reduction. 3. Our understanding is that the price of CO2 varies geographically, so it will depend on where in the country we're capturing CO2. We're still testing the exact purity of our CO2, but it's definitely > 95% and we believe we can get it to > 99%. What purity does your company use? 4. It only takes trucks a few minutes to offload the CO2. They don't have to unload or reload anything - they just have to attach a hose and the device pumps the CO2 into the offload tank. We want to make this as easy as possible for drivers. Our first partners are actually very large companies that own private fleets of semi trucks and have aggressive climate commitments, so they have a little bit more wiggle room to test new technology! 5. That's exactly our plan. In the short term, we'll be earning revenue by selling to the concrete producers or other industrials. In the medium term, we'll be mainly be earning revenue by permanently sequestering our CO2 deep underground. Let me know if I missed anything!
- boringg 6y agoSounds like you have a good roadmap. That offtaker piece is a tricky one and the long term storage piece is policy dependent. Hopefully other CO2 markets materialize. Our process is 99% purity.
