We trained at big engineering companies so secrecy is our M.O.! For better or worse... We can & must show more to the community as we get to pilot scale. We know that people/society needs to see more physical examples CO2 removal t

We'd rather not speak to anyone else's technology, except to say that we support anyone working on CO2 removal & have only gratitude & respect to pioneers in this ecosystem, including Climeworks, who paved the way for CO2

Right now, there is an ongoing discussion between a huge variety of stakeholders -- CO2 removal startups/companies, academics, regulators, 3rd-party verification standard-setting bodies, etc. -- to figure out what kind of life cycle an

You are absolutely correct that desorption is the energy-intensive step in many CO2 capture systems that have been publicly proposed. I can't get into the specifics, but keeping the desorption energy as low as possible is a major focus

Great question. Point source capture & removal/conversion solutions from flue emissions are desperately needed, as are tech/policy solutions to help eliminate emissions to begin with! For now, we are focusing on CO2 removal fr

Great question. We'd love to capture point-source CO2 from factory flue gas where it is orders of magnitude more concentrated (often >10%) than in air (~400ppm). And fundamentally, there is no reason our process cannot be applied fo

Right now, it's >5MWh/ton using lab scale equipment. At 1 million ton per year scale, we expect closer to 1-2MWh/ton.

Thank you - we appreciate it!

Today at lab scale it is quite high at >$1000 ton. At the 1 million ton per year scale, we expect our process to come in at <$100/ton.
