Please correct me if I get the numbers wrong but if that is the price, that means the price of 1 ton Gallium is $300,000 per ton
From [another comment](https://news.ycombinator.com/item?id=29990056 https://news.ycombinator.com/item?id=29990056) I got that the ratio of CO2 to Ga would be 1 to 2. So in order to reduce 1 ton of CO2 you'll need to spend $600,000. That seems insane. Especially when the damage done per ton of CO2 is usually valued at ~$200.
- gumby 5y agoThe Ga is a catalyst, so it’s a cap ex not op ex. I’m dubious but open to try anything halfway plausible at this point.
- laci37 5y agoThe abstract says the process produces gallium oxide. We would need to recycle that into gallium, which is probably energy intensive.
- spartanatreyu 5y agoPretty sure the Gallium can be recycled.
