Problems with Algae-based Carbon Capture Posted by Parkavi on Mon May 10 2010 05:32:30 AM 26

Hello all!

I am researching on the problems faced by companies implementing algae based carbon capture technology. Although there are several advantages with algae as a biological carbon sequestration agent, the real problem could be the technology behind the cultivation of algae for the same.

I want to understand the problems with implementation and scaling up of algae based carbon capture technology for carbon capture in power plants or other CO2 emitting industries.

I understand one major problem could be the availability of land near the industry. Please provide similar inputs which you think could be a problem for with the algae-based carbon capture technology.

Thank you!!

Algae-based Carbon Capture Technology - Status and Trends Posted by Parkavi on Fri April 16 2010 03:23:51 AM 7

Atmospheric CO2 levels have risen due to fossil fuel combustion, and are the major reason for global warming. This has made every single country to put some considerable efforts to reduce carbon emissions, and is the driving force behind the new technologies that are emerging for carbon capture and storage. The conventional CO2 sequestration processes like geological sequestration are highly power-intensive and as a result, expensive. Algae-based CO2 capture offers a cost effective carbon capture system and also solves another major problem for many countries: Imported fuel dependency; algae-based CO2 mitigation strategy has the potential to obtain valuable products at the end of the process, one of which is biofuels.

Several researches have been attempted in recent years to grow algae using CO2 from power plant emissions, cement plant emissions and distilleries emissions. But all these efforts are in pilot stages. All these efforts face a number of challenges such as cost, technical feasibility etc. Another major challenge is the land availability for algae-based CO2 capture system near a power plant. A 300 MW power plant could require as much as 8,000 acres of cultivation area to capture the CO2 emitted. There are other significant challenges as well. Unless we decipher ways to grow more algae in less space at a much lower cost, algae-based CO2 capture cannot be commercialized.

Currently, there are a number of research efforts and few major collaborations working to commercialize algae-based carbon capture technology. Large companies such as Duke Energy, the third largest electric power holding company in the United States are working on this carbon capture technology. A number of universities have started taking a special interest in biological forms of carbon capture, including using algae as the bioremediation agent. Government policies, especially in the US and Europe, have also started supporting the growth of algae-based carbon capture technology.

If the challenges associated with Algae-based carbon capture technology are addressed sucessfully, the technology will present a solution not only to the global warming issue but also to the fuel demand.

Microalgae Biofixation Network Posted by Parkavi on Sat April 03 2010 04:12:16 AM 3

When I was browsing through IEA Greenhouse Gas R&D Programme website (http://www.co2captureandstorage.info/networks/Biofixation.htm), I came to know that the organization has a separate wing for Microalgae-based carbon capture: International Network on Biofixation of CO2 and Greenhouse Gas Abatement with Microalgae.

The Microalgae Biofixation Network was started in June 2002. The Microalgae Biofixation Network provides a structure and mechanism by which expertise can be shared, critical mass reached and research projects co-ordinated to help focus R&D efforts on the most promising approaches towards practical applications.
The objective of the Microalgae Biofixation Network is to promote the research and development of microalgae-based greenhouse gas abatement technologies over a ten year time horizon. These objectives will be accomplished through:

## Information sharing and co-ordination of R&D projects carried out by Network members
## Development of bi- and/or multi-lateral R&D projects among members
## Technical assistance provided by technical advisers in the evaluation of proposed processes and R&D projects
## Supporting techno-economic analysis and resource assessments
## Organisation of technical meetings and technical resources
## Develop a periodic updating of a 'Roadmap' that details feasible processes and R&D approaches

A study conducted by biofixation network evaluated the applications and potential contributions, on a regional and global scale, of microalgae biofixation processes mainly in conjunction with the treatment of municipal and agricultural wastewater. This report can be obtained by sending an e-mail with the company's name and address to Dr. John Benemann, The Biofixation Chairman @ JBenemann@aol.com.

This report was carried out by TNO for the International Network on Biofixation of CO2 and Greenhouse Gas Abatement with Microalgae and was sponsored by EniTecnologie S.p.A., the R&D arm of the Italian oil & gas company Eni. It is intended as a strategic tool for R&D personnel and managers, policy makers, and others who are interested in evaluating the various technology options, including biological, for GHG abatement as well as related environmental and sustainability issues.

I will send a request mail right away for the report, and will update the status soon.
