Cost, meaning what does the equipment cost to buy and operate? The cost of equipment will be coming down fast. It needs, anyway, a supply of hydrogen and carbon. As hydrogen gets more valuable for other processes, its price might even go up. Extracting carbon from the atmosphere costs a few hundred dollars a ton; that cost might go down. The oxygen has to be stripped off, which costs energy you will hope to get back.
