Yeah, that's the core of it. Climeworks absorbs CO2 on their amine solid sorbent surface before releasing it by heating up the sorbent to prepare it for a new round of CO2. That CO2 then needs to be stored somewhere. I'm not familiar with the inner workings of Climeworks, but if I were there that would be what concerned me the most. I know they're testing a mineralization solutipn with Carbfix in Iceland that could be promising, but expensive. We're not at sufficient scale to offer credits to consumers. but this could be on the agenda in a few months. As for cost per tonne this depends a lot on the commercial arrangements we have in place. More meaningful is the energy consumption per tonne which is <4 MWh/ tonne. This will be reduced to 3MWh/tonne. Based on current commercial conversations we're expecting a CO2 price below $50/t for our first plant
- Aachen 5y ago$50/t sounds amazing! That would be a price point where I could offset 100% of unavoidable CO2e emissions quite easily. Too bad it won't initially be available for consumers, but I'm very much looking forward to seeing where this goes :)
