CO2 Transport R&D Project Launched by EU COCATE

Posted by on Monday, 1 March, 2010

The project brings together eight other research and industrial partners: the Le Havre Region Development Agency (France), Geogreen (France), Accoat (Denmark), SINTEF Energy Research (Norway), DNV (Norway), TNO (Netherlands), Port of Rotterdam NV (Netherlands) and SANERI (South Africa).

COCATE’s objective is to analyze the conditions for transporting the flue gases emitted from several CO2-emitting industrial facilities with a view to pooling the capture process, and for exporting large quantities of captured CO2 to storage areas. While major industrial facilities can be fitted with their own CO2 capture and transport installations, this does not apply to units that emit less CO2 – from a few tens of thousands to several hundred thousand metric tons – and for which the investment required would be uneconomic. They must pool the CO2 capture and transportation system in order to cut costs and to make CCS an affordable technology.

So far, all the R&D projects in the CO2 transportation field have been exclusively focused on the CO2 emitted by the major emitting industries, in particular power stations. As the first project dedicated to the issue of pooled CO2 treatment, COCATE should allow medium-sized production sites located in the same geographic area to cut their CO2 emissions in the same way as major industrial facilities.

Interesting. I have not heard of pooling the flue gases for CO2 treatment so far. Am not sure if the economics works out better this way. Which will cost less? Individual capture infrastructure at multiple locations but transporting only CO2 or a single capture mechanism that involves transporting the entire flue gas. Well, thinking about it again, it appears that there is a chance that the latter could indeed cost less. Let’s hope for good results from this experiment.

CO2 Solution Joint Development with Codexis with Enzymatic Method

Posted by on Monday, 1 March, 2010

Under the collaboration, CO2 Solution’s proprietary enzymatic method for CO2 capture from coal-fired power plants and other large sources of emissions will be combined with Codexis’ directed enzyme evolution technology.

CO2 Solution’s technology uses the natural enzyme carbonic anhydrase to enhance CO2 absorption efficiency from power plant emissions, at lower cost than conventional technology.
Codexis’ technology will be used to improve this enzyme’s ability to function in harsh industrial conditions. Carbonic anhydrase is found in humans and other mammals and is critical in the efficient management of CO2 during respiration.

CO2 Solution and Codexis will also cooperate on Canadian and U.S. government funding opportunities for the technology as well as customer and adopter opportunities.

Cryogenic CO2 Capture Using Cold Energy from LNG

Posted by on Monday, 1 March, 2010

Cryogenic CO2 capture using cold energy from LNG : innovative synergies between LNG terminals and nearby industries.

Within the R&D activities on CO2 capture, transport and storage, GDF SUEZ Innovation & Research Department is conducting a series of studies on the three main options for capture (i.e. oxyfuel/chemical looping, pre-combustion and post-combustion), the two options for CO2 transport (i.e. pipelines and ships) and CO2 storage in partnership with universities, R&D centers, industries and the French National Research Agency (ANR).

Innovative options for capture :
As part of GDF SUEZ Innovation & Research Department, CRIGEN was also involved in an innovative CO2 capture technology using cold, through the ANR Project CO2Sublim built around a partnership with ARMINES1 , which has developed a process for CO2 capture by frosting (“antisublimation” in French). A laboratory mock-up has already been built by ARMINES in order to validate the concept feasibility. The project was proceeded between November 2006 and end of February 2008.

As a next step, CRIGEN and its partners are developing an improvement of this CO2 cryogenic capture system – allowing energy consumption decrease – using free cold from LNG available on LNG terminals.

This technology uses the cold energy released during LNG re-gasification process to freeze out and then liquefy the CO2 from industrial flue gases (power plant, steel or cement industry …). The high-pressure liquid CO2 could be easily transported by ships for Enhanced Gas or Oil Recovery application or for geological storage.
By using potential synergies between a CO2 source and a LNG terminal, this technology will significantly reduce the cost of carbon dioxide capture. Thus, this technology process could be a good alternative to CO2 solvent technologies and presents many advantages such as :
-> Atmospheric capture of diluted flue gases (like solvents processes),
-> High purity of captured CO2,
-> Integrated removal system of common pollutants in the flue gases,
-> Liquefied and pressurized CO2 ready for shipping or pipeline transportation,
-> Less energy consumption than amines technologies,
-> Thermal and physical process instead of chemical process (solvents),
-> Reduced impact of CO2 capture on global efficiency.

Purenergy CCS 1000 – Prefab CO2 Capture Equipment

Posted by on Monday, 1 March, 2010

Purenergy CCS 1000 is a standalone carbon capture system that will capture CO2 from the flue gas exhaust of power plants and large industrial emitters. It will be capable of capturing 1000 tons per day of CO2.

The system is pre-engineered, pre-built and modularly constructed in Saskatchewan by HTC’s strategic partner Pinnacle Industrial Services of Regina using technologies developed and validated at the University of Regina.

The company believes, because of its modular design, that it will be able to be manufactured, shipped and erected at the emitter sight at a much lower cost than other systems that have to be custom built on site.

HTC Purenergy is globally commercialising this product through its head office in Regina (Canada), and commercial offices in Sydney (Australia), Beijing (China), and Vermont (USA).

Large Scale Carbon Capture Farming to Rebuild Soils

Posted by on Monday, 1 March, 2010

USGS, California and UC Davis begin large-scale Delta “carbon farm” Project will study best ways to capture atmospheric CO2, reverse island subsidence

The U.S. Geological Survey (USGS), the California Department of Water Resources (DWR) and the University of California, Davis plan to make it happen.

DWR has awarded USGS and UC Davis a three-year, $12.3 million research grant to take the concept of carbon-capture farming to full-scale in a scientifically and environmentally sound way.

Long-standing farming practices in the Delta expose fragile peat soils to wind, rain and cultivation, emit carbon dioxide (CO2) and cause land subsidence. To capture or contain the carbon, farmers would “grow” wetlands. In doing so, they would begin to rebuild the Delta’s unique peat soils, take CO2 out of the atmosphere, ease pressure on the Delta’s aging levees and infuse the region with new economic potential.

Carbon-capture farming works as CO2 is taken out of the air by plants such as tules and cattails. As the plants die and decompose, they create new peat soil, building the land surface over time.

Construction on the new wetlands, covering up to 400 acres on Twitchell Island, is scheduled to start in the spring of 2009.

Throughout the Delta, oxidation of the soils from farming practices has resulted in land-surface subsidence – a steady loss of elevation. As a result, most of the farmed Delta islands are more than 20 feet below the surrounding waterways and are permanently protected by levees.

The falling land surface threatens the stability of the region’s levees, which in turn protect the Delta’s rich agricultural lands and the conveyance of much of California’s water supplies. Water flowing through the Delta’s levee-protected farmland provides fresh water to more than 25 million Californians and millions of acres of farmland in the Central Valley.

Plastic Membranes for CO2 Separation and Capture

Posted by on Monday, 1 March, 2010

A polypropylene membrane carbon dioxide separation system has been developed by the University of Melbourne, Australia, which could be used in power plants, according to an article published in Australian business / environmental magazine ECOS.

Teflon membranes have already been used in pilot carbon capture systems, but polypropylene is much cheaper.Polypropylene was previously rejected as a potential membrane material because it could be wet by the aqueous solvents used to absorb carbon dioxide from gas.

Canada’s Regina University, the University of Trondheim, Twente University in the Netherlands, and the University of Texas are collaborating on the project.A pilot project will be built next year to process 25 tonnes of carbon dioxide a day.

CarbonSaver Technology from Atlantic Hydrogen Tests Carbon Removal

Posted by on Monday, 1 March, 2010

CarbonSaver technology involves subjecting natural gas to an electrical charge, causing the carbon and the hydrogen molecules to split. The hydrogen is then mixed back with natural gas to produce HENG with around 20% hydrogen, reducing CO2 emissions when it is burned, while the carbon is removed as a solid.

The CarbonSaver Demonstration Project, which will be located in Fredericton, New Brunswick, is expected to take three years to complete, starting in the summer of 2008. It will involve building a plant capable of generating HENG at volumes greater than 1,000 cubic metres per hour and at pressures between 50 and 150 psi.

Low-Cost CO2 Mitigation in Electricity, Oil, and Cement Production

Posted by on Monday, 1 March, 2010

Abstract

Several low-cost opportunities exist for scrubbing CO2 from waste gas streams, utilizing spontaneous chemical reactions in the presence of water and inexpensive or waste alkaline compounds. These reactions convert CO2 to bicarbonate or carbonate in dissolved or solid form,
thus providing CO2 capture and low-risk CO2 storage underground, in the ocean, or in some cases on land. Useful by-products and co-benefits can also be generated by these processes. In certain
settings this approach will be significantly less energy intensive, less costly, and less risky than “conventional” molecular CO2 capture and geologic storage.
