The third, and most vexing, problem has to do with scale. In 2009, carbon dioxide emissions in the United States totaled 5.4 billion tons. Let’s assume that policymakers want to use carbon capture to get rid of half of those emissions – say, 3 billion tons per year. That works out to about 8.2 million tons of carbon dioxide per day, which would have to be collected and compressed to about 1,000 pounds per square inch (that compressed volume of carbon dioxide would be roughly equivalent to the volume of daily global oil production).
In other words, we would need to find an underground location (or locations) able to swallow a volume equal to the contents of 41 oil supertankers each day, 365 days a year.
There will also be considerable public resistance to carbon dioxide pipelines and sequestration projects – local outcry has already stalled proposed carbon capture projects in Germany and Denmark. The fact is, few landowners are eager to have pipelines built across their property. And because of the possibility of deadly leaks, few people will to want to live near a pipeline or an underground storage cavern. This leads to the obvious question: which members of the House and Senate are going to volunteer their states to be dumping grounds for all that carbon dioxide?
