I'm confused, isn't the price of co2 very low? I would guess the oil and gas industry have a lot of co2 to spare. Have you tested this process and mixture?

- jsantos511 6y agoGreat question - the oil and gas industry is definitely responsible for a huge chunk of CO2 emissions, but they are not the ones that produce CO2 used commercially. Most CO2 that is used at breweries, restaurants, etc comes from ethanol plants: https://www.attisbiofuels.com/by-products/carbon-dioxide https://www.attisbiofuels.com/by-products/carbon-dioxide From conversations we've had with CO2 buyers, the price for CO2 ranges from between $150-5,000 / ton depending on things like how much is being bought, length of time committed in a contract, etc. We have tested this mixture out with the industrial prototype in our office, yes! We've shown our cooling tower is able to capture CO2 from the air, and we are able to regenerate and pressurize that CO2 into cylinders.
- jokoon 6y agoCant edit. Also, would it be effective to build new cooling towers? Our doors it work only where there's a source of co2?
- jsantos511 6y agoBuilding new cooling towers would drive our costs up as we would have to pay for the capex of the towers in addition to the rest of the process. For now, we are trying to keep everything as low-cost as possible. Cooling towers typically run outside since they sometimes have water evaporating out the top of them, but even if cooling towers were inside, this would still be a great solution. CO2 concentrations indoors are sometimes even higher than the ones outdoors, which may allow for even higher carbon capture amounts than outdoor systems would.
