Construction has begun on a unique refinery project that will convert Canadian bitumen into ultralow-sulfur diesel while producing high-purity CO2 for enhanced oil recovery (EOR) and subsequent carbon capture and sequestration (CCS). The project, located near Edmonton, Alta. and run by the North West Redwater Partnership (Calgary, Alta., Canada;, combines a set of proven...

AkzoNobel N.V. ( has partnered with Dutch start-up company Photanol (both Amsterdam, the Netherlands; to manufacture specialty chemicals using a photosynthesis-like process that combines sugar production with fermentation in a single organism. Photanol has developed genetically engineered cyanobacteria that are capable of consuming carbon dioxide and sunlight to make...

Last month, NET Power, LLC (Durham, N.C.; announced the completion of major project agreements for its first-of-a-kind power plant — a 50-MWth demonstration plant that will validate the world’s first natural-gas power generation system that produces no air emissions, and includes full CO2 capture without requiring expensive, efficiency-reducing carbon-capture equipment. The...

Last month, the first commercial-scale, post-combustion carbon capture and storage (CCS) plant started up in Saskatchewan, Canada. The SaskPower facility at the Boundary Dam Power Station is expected to capture around 1 million m.t./yr of CO2, which is up to 90% of CO2 emissions from...

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; 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; 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, 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; 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; 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; the Dept. of Chemical Engineering, Monash University ( and the School of Chemistry, University of Sydney...

Researchers from Newcastle University (U.K.; 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;

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; 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...

Advanced Algal Technologies (Sydney, Australia; has signed a $100-million deal with Fuzhou Xiangli Enterprise Management Consulting (Fuzhou, China) — an LED-lighting manufacturer — for a license to build 500 algal-farming-conveyor modular units per year. These units will be used to reduce carbon dioxide emissions in manufacturing plants in China. Traditionally, algae have...

Electrochemical and chemical-precipitation technology from New Sky Energy (Boulder, Colo.; allows the conversion of salty wastewater and CO2 from fluegas into valuable process chemicals, such as soda ash, calcium carbonate, sulfuric acid, bleach and other chemicals. New Sky’s customizable system is designed to be installed onsite at a processing facility to work with the...

At Achema 2012 (June 18–22; Frankfurt am Main, Germany), Union Engineering A/S (Fredericia, Denmark; will be presenting its patented FlashCO2 process — both at the exhibition (Hall 9.1, Stand E29) and in a congress lecture (Monday, June 18th at 11:30 in the room Illusion 2). FlashCO2 enables liquid CO2 to be produced from H2 plants at a direct operating cost of around...

Construction of a 1-hectare (ha) carbon-capture and recycling “synthesizer” demonstration plant has started at Tarong Power Station near the town of Nanango in southeast Queensland, Australia. Tarong Power Station comprises four coal-fired units with a gross generating capacity of 1,400 MW. The plant — a joint initiative between MBD Energy Ltd. (Melbourne, Australia;
