In recent years, facilities that generate large amounts of carbon dioxide, such as fossil-fuel-burning power plants, have begun capturing their death gas output at-source. Called "carbon capture and storage," or CSS, plants use a variety of fancy filters to catch the carbon before it can float away, and then transport it to facilities where they pump it as deep underground as they can. It's the bizarro lava game; all we have to do is keep the gas touching the ground, and we're safe. And if that means dooming all the mole people down below to a smoggy genocide, that's a price we'll gladly pay for being able to drive to the corner store without the guilt trip.
The crazy thing, however, is that it's working, for the most part. While it is claimed CSS can grab up to 90 percent of emissions for storage, there are concerns that we're pumping it into geological bedrocks that are porous enough to eventually allow the gas to escape, making this whole endeavor a complete waste of time. We're getting better and better at figuring out the process, though, and one team has already devised a solution to the solution: turning the gas into rock.
In an experiment carried out in Iceland, tons of carbon dioxide were dissolved into a veritable pond of acid. This carbonic acid was then injected into a volcanic rock called basalt, which makes up most of the island, and over time combines with other elements to form minerals like limestone. The results were staggering. Not only did the process take months instead of years, but when they analyzed the results, they found that a whopping 95 percent of the carbon they'd bukkaked into the void had been converted into rock. This massive success has led to further experiments in other basalt-rich areas of the world, and even the building of the first "negative emissions" power plant in Hellisheidi, Iceland. This bad mamma-jamma shoots its noxious emissions straight into the Earth to be turned into stone, ready to be excavated in several years' time and used to build a giant middle finger aimed in whatever direction Scott Pruitt's house is.
