A new plastic made from CO2 and butadiene has been synthesized by Kyoko Nozaki and her research group at the University of Tokyo (Tokyo, Japan; www.chembio.t.u-tokyo.ac.jp/labs/nozaki). Although butadiene is already produced on a large scale for making synthetic rubber, it has previously been impossible to copolymerize CO2 and butadiene in a single-step reaction, because the...

The first phase of a study on the feasibility of producing methane from CO2 has been completed by Hitachi Zosen Corp. (Tokyo; www.hitachizosen.co.jp) and Daiki Ataka Engineering Co. (Daiki Ataka) a subsidy of Hitachi Zosen, in collaboration with PTT Exploring and Production Public Co. (Thailand). The companies have been collaborating since 2012 to develop a methanation process to convert CO2, which is generated...

Professor Susumu Kitagawa’s group at Kyoto University (Kyoto, www.sbchem.kyoto-u.ac.jp/kitagawa-lab/index-e.html) has developed a new soft nanoporous material that selectively adsorbs carbon monoxide from gas mixtures. The researchers believe their achievement will enable the separation and recycling of CO from the emissions of many large-scale industrial...

A pilot plant will be established at the University of Newcastle (Newcastle, Australia; www.newcastle.edu.au) to test a new technology for the sequestration of CO2 through mineral carbonation — the reaction with magnesium silicate minerals, such as serpentine, to form mineral carbonates. Mineral carbonation mimics and accelerates the Earth’s natural carbon-sink mechanism by combining CO2 with...

Researchers at the University of California Irvine (UCI, Irvine CA; www.chem.uci.edu) have taken a cue from nature in devising a way to remove carbon dioxide from fluegas. They are developing a synthetic membrane based on the design and function of birds’ lungs. “Birds’ lungs are the most efficient mass exchangers in nature and have one of the highest specific surface areas known,”...

Cement manufacturing is a major source of greenhouse gas emissions due to two factors: carbon dioxide is released when calcium carbonate calcines to lime (CaO) in the cement manufacturing process; and cement kilns are operated at temperatures of 1,500°C, which requires significant fuel consumption. Cement is the agent that binds sand and crushed rock together to form concrete. Solidia Technologies...

Ammonia is a promising candidate for scrubbing carbon dioxide from fluegas, since each ammonia molecule can absorb one molecule of CO2, whereas amine absorbers require two molecules to do the same job. However, because ammonia is volatile, the fluegas must be cooled to about 10°C. This requires a lot of electrical energy, points out Indira Jayaweera, a senior staff scientist with SRI International...

An Australian team has developed a structure made of a metal organic framework (MOF) that captures and then releases CO2 using natural sunlight. The team includes researchers from: CSIRO Division of Materials Science and Engineering, (Clayton South, Victoria; www.csiro.au) the Dept. of Chemical Engineering, Monash University (www.monash.edu.au) and the School of Chemistry, University of Sydney...

Researchers from Newcastle University (U.K.; www.ncl.ac.uk) have discovered that, in the presence of a nickel catalyst, CO2 can be rapidly and cheaply converted into solid carbonate salts. The discovery could lead to a simpler and less-expensive alternative for carbon capture and storage (CCS). Led by Lidija Šiller, a physicist and Reader in Nanoscale Technology, the researchers were investigating...

An Australian team has developed a new molecular sieve that allows carbon dioxide molecules to be trapped and stored. Contrary to the way molecular sieves usually work, allowing smaller molecules through, the new sieve acts like a trapdoor, and allows larger molecules through, blocking smaller ones. The team, led by professor Paul A. Webley of the University of Melbourne (Australia; www.unimelb.edu.au)...

An electrochemical process that could cut the energy and cost requirements for stripping carbon dioxide from stack gases by half is being developed at Arizona State University (ASU, Tempe; www.asu.edu). At present the only commercially viable technology is CO2 absorption by monoethanolamine (MEA), says Dan Buttry, chair of ASU’s Department of Chemistry and Biochemistry. However, he notes that a...

Plans are underway to field-test a process that removes more than 90 % of the carbon dioxide from power-plant flue gas, while reducing both the energy input and operating costs by 50 % compared to conventional amine-based CO2-scrubbing technology. The so-called carbonate-looping process has undergone four years of testing in a 1 MWth pilot plant at the Technical University of Darmstadt (Germany...

A rapid pressure-swing-adsorption (rPSA) system to separate carbon dioxide from fluegas is being developed by W.R. Grace & Co. (Columbus, Md.; www.grace.com) and three partners under a $3 million grant from the U.S. Dept. of Energy (DOE; Washington, D.C.; www.energy.gov). The goal is to develop a process that costs half as much as current amine systems, whose cost is $50–70 per ton...

A project aimed at using geothermal heat to power an electricity-producing turbine with supercritical carbon dioxide has received a $5 million grant from the U.S. Dept. of Energy (DOE; Washington, D.C.; www.energy.gov). The project also incorporates an element of CO2 sequestration in sedimentary rock, whereby a portion of the CO2 injected into the hot sedimentary layer remains there, so that the process...

Scaleup is set for two technologies that facilitate the capture of carbon dioxide from fluegas by substituting oxygen for combustion air. Oxycombustion, as it is called, results in a much smaller fluegas stream, containing up to 90% CO2; part of that is recycled to dilute the O2 and control the combustion temperature. The O2 is entrained in the CO2 stream for injection into the furnace. The companies...
