Carbon dioxide (CO) in competition to combat climate change2) Emissions are advertised as an easy way to reach net zero emissions by 2050. The science behind carbon capture is sound, but current technology is expensive and not optimized for all configurations.Cover story Chemistry & Engineering NewsThe American Chemical Society’s weekly news magazine focuses on the work being done to improve the current state and process of carbon capture.


Improving efficiency and renewable energy sources can help, but they are often expensive and not enough to compete with billions of tonnes of CO.2 Every year it is sent to the atmosphere, writes Deputy Editor-in-Chief Craig Bettenhausen. Carbon capture technology implemented at CO sources2 Emissions such as Power plant, These emissions can be significantly nullified. Despite that promise, only one commercial power plant is using this technology today.Interestingly, with oil Gas company— Major producers of CO2 Emissions — Inspired by competition for cheap renewables and consumer demand for low-carbon options, it is unlikely to become an ally of those developing capture methods.

Currently, the most common form of carbon capture uses solvents to absorb CO.2 Allows other less harmful gases to pass through. This method is well understood, but it is not a particularly “green” solution as it requires up to 50% of the plant’s energy output. Scientists are working on the development of next-generation carbon capture technology, where solid adsorbents and membranes are promising.These materials require less energy and are already used at some CO-intensive sites2 Emissions. The immediacy of this issue has led companies to begin developing other methods, such as cryogenics and the use of organometallic frameworks to absorb gas.While the U.S. government works with businesses to provide subsidies Carbon captureCritics say it distracts from investment in renewable energy and polluter regulation. Progress has been made, but experts warn that the next decade will be the crucial time to find a CO solution.2 Emissions.
