Unless the CO2 is pumped back into the ground to stay, it's going to wind up in the atmosphere. However, if the CO2 can be used multiple times before it winds up in the atmosphere, that's definitely an improvement. One rather reasonable way to transition to an electrically-powered transportation system would be to generate electricity with coal to power EVs, capture the CO2 released from the coal at the smokestack, and then use solar and wind power to turn that CO2 into hydrocarbon fuels for vehicles with internal combustion engines. The overall result is to significantly extend the number of road miles per ton of CO2 we currently get. And, in the process, it builds out the carbon-free generating infrastructure that will eventually replace fossil fuels entirely. Also, if you have a plant that can turn compressed CO2 into liquid fuels...if you have surplus energy, as one would have after building enough solar generating capacity, you can extract the CO2 from the atmosphere and pump the liquid fuels you make back under ground. It's not unreasonable to suggest that, a couple centuries from now, if we were serious about it, we could thereby have returned atmospheric CO2 levels to those before the Industrial Revolution. I don't like coal...but I'm careful to not let the perfect be the enemy of the good. If significant progress is made in the right direction, it's a good idea to at least not object excessively vigorously. b& -------------- next part -------------- A non-text attachment was scrubbed...
