Reducing carbon emissions is a subject that Paul Comet, Houston scientist, is passionate about. He has spent much time researching the topic, following the latest developments, and coming up with his own ideas for reversing climate change. According to a recent article on Phys.org, researchers may have come up with a more effective method to “scrub” carbon dioxide from fossil fuel emissions. This new method is more easily implemented into current power plant facilities.
The current methods of removing carbon dioxide from emissions involve installing a complex plumbing system to divert steam, which is not practical at many power plants. Amines, a chemical compound that binds with CO2, release gas when heated. Right now this happens in a separate chamber and requires the diversion of approximately half of the low-pressure steam generated by the plant.
The new system, developed by researchers at MIT, utilizes an electrochemical system as opposed to using steam. Rather than using steam to separate amines and CO2, it uses electricity. The amines are introduced at the top of the absorption column and then are collected in liquid form at the bottom. An electrochemical process would then release the CO2 and make the amine reusable. It would also only use approximately 25 percent of a plant’s power output compared to the 40 percent used by conventional CO2-capture processes.
According to Paul Comet, Houston scientist, “This is an excellent new technology which solves many earlier problems. However, the main problem – what to do with the recovered CO2 – has not been solved and essentially the CO2 tin can has just been kicked down the road. Various suggestions for CO2 sequestration have been proposed: reinjected CO2 used for rejuvenation of old oil reservoirs has the problem of leakage. The CO2 is highly fugitive and would tend to escape from old repressurized onshore depleted oil fields. This can potentially form a lethal heavy blanket which stays close to the ground when the wind drops off. In offshore fields, natural oil and gas seepage is exhibited showing that leakage is commonplace and can be easily seen by observing the bacteria and animals that feed off natural gas. It is possible, however, that the loss of CO2 from a depleted offshore field undergoing secondary recovery will occur slowly enough to be useful. Nevertheless, this approach would be costly.”
A second option according to Dr. Comet is, “If the CO2 is converted into blocks of dry ice and thrown into the ocean, it would sink and be partially removed from the carbon cycle. However, the CO2 would dissolve in the ocean, and if implemented on a commercial scale, would tend to acidify the oceans further. This might drastically change worldwide marine ecosystems. A third option is using the CO2 for industrial purposes. Carbonated beverages, plastics and other things would not cope with the enormous amounts of CO2 suddenly available.”
Paul Comet, Houston scientist, offers his own insight what might help. “It might be better to absorb the diluted CO2 directly out of the air using a non-point source strategy,” he says, “such as tree planting or ecological restoration and maintenance, particularly wetlands restoration. Biochar deposition from agricultural waste is another option.” Scientist Paul Comet, Houston, continues to come up with potential ideas for reversing climate change.
