One nice thing about this is that you could pull carbon out of the atmosphere from remote locations, in particular hydro electricity could provide abundant, inexpensive, and clean power.
- njarboe 8y agoJust what I was thinking. Like west Texas with wind where electricity prices go negative quite often in the middle of the night.
- DoctorOetker 8y agoguys, capturing CO2 or not releasing it at a power plant are the easy and cheap part. It's what you do with the voluminous CO2 gas. Converting to fuel will be very expensive (although if the conversion process can be throttled quickly, which I highly doubt, we could use peak solar and wind, and treat fuel as a battery). The figures you calculate is meaningless, factories could always have been fitted with carbon capture for a relatively low energy cost. The reason this is not done at scale is there is zero demand for CO2! (unless you pay someone carbon credits to pretend to need CO2!!!)
- linkregister 8y agoYes, at that scale, the price of CO2 approaches zero, especially with the caveat that it shouldn't be reintroduced (as with carbonated beverages and pressurized machinery). Carbon dioxide sequestration or transformation is the next step. Getting the first step to be economical is also nice.
- njarboe 8y agoCO2 injection is already done in many oil fields for enhanced oil recovery. People already know how to pump it down into the earth and track where it goes. Put a decent price on removing CO2 from the atmosphere and people will quickly figure out how to do it for a nice profit. Lots of old oil wells in west Texas also.
