As long as the CO2 comes from coal the only green thing about it is that it delays the time before the CO2 is released to the atmosphere.

I which they would develop this technology so that the algae could use CO2 from the atmosphere instead. Alternatively why don’t they use an ethanol plant? They also produce CO2 in large volume and it is much closer to be CO2 neutral than coal.

One problem with underground coal gasification is that you have to move the operation when you have utilised the coal from a particular location. You basically gasify the coal in situ. If it can be made economically viable you can however drill horizontally out to sea so opening up more reserves.
My prefered option with the C02 captured by algae would be to dry it and transport it to a coal carbon capture and sequestration power plant, there it could be co-fired with coal and the C02 would be stored permanently underground.
Does anyone have any idea as to what area would be required, to capture the C02 from say a 500MW coal fired power plant?
Another interesting point about this approach is that it would make C02 capture more viable in isolated locations for instance in regions of China.

I Understand from this report that the intention is to attempt to sequest some CO2 via a solidified lignin process as yet undescribed. I dont know that that process could be particularly relevent to or the best utilization of the product stream. I Recall a conversation with a fellow decades ago re the use of a paper like product tha was applied as a road sufacing anothe ruse may lie in the area of high grade paper, or even the mainstrem paper making industry. That would make consevationists and environmentalists happy. Offsetting tree pulping. One would have to think that carbon storage in wood already produces a quality storge mechanism, depending on species and end use. Useful Life Expectancy 'ULE'. Not much storage if the product life is less than hundreds of years. Logically the longer life the better the outcome. Ideally , and the way nature has (one should assume for good reason) been at this Sequestration model is to store carbon in the form of sinks like coal or oil. We too easily dismiss nature as a Dumb mechanism and that certainly goes against our understanding of climate science and modification in The natural environment. Lets face it planetary life forms have always altered the composition of earths atmosphere and it is
through these processes that the current life forms have evolved.
You cant blame them for trying, But I thought it was already established hat a near 0 carbon future is the only viable option. It's a shame that buisness think a little spin will keep us in the dark.
In fact the balance of comments here should serve as a warning to unethical companies that they bare simply raising our awareness while sinking heir own ship.
The military AND OTHER Backroom dealers might get away wih this attitude for a while yet. But I stress only a little while.
Previous posts are indeed revealing.

This article is about producing algae from CO2, which is green. What ever the CO2 source.

Then there is the question of coal which is a separate issue. Sure coal is the worst at MJ/CO2 but it is still being used. We should look at ways to clean it up because it is not going away.

I meant environmentally friendly in that there is no open cast mine. What's the problem about Fisher-T? That it's energy inefficient? Or that people use it to make transport fuels? Because the second it not really a problem with FT, just with what it's used for.

Talking of clean technologies do you know of ESI www.ectltd.com.au and GHT, www.geothermal-resources.com.au these technologies are not getting the investment interest they need but you watch, when they reach paydirt i.e. geothermal hot rock for power generation, their share prices will go throught the roof and pollies will undoubtedly take credit. ESI by the way almost whent into bankruptcy, a technology that produces a cleaner coal (sounds like an oxymoron) and unless we pay carbon tax these technologies may not get through, check em out.

Hi, RM I'm sure you wont mind me posting your reply.
By way of introduction.
The state of play so far.
Mysteriosly Linc energy and "Professor" now 'doctor' Andrew Lowe an apparently reputable horrticulturalist involved in numerous projects including a 5 Million Euro project. Have both seen fit to pull the references from their web sites.Linc energy have pulled 12 months of dodgy press releases. And now no mention of the "green" coal so loudly trumpeted on this site. and numerous media releases over the last few weeks in particular. Good work at cleaning up the sites boys but like I say you picked the wrong crew.
How do I know? . I got the copy.

This co and readers be sure that there are other scammers out there trying to cash in on the clean green
thats a given . No brainer.
I'll be writing more on this matter in greencarcongress.com as I can
Meanwhile I suggest readers go to the sites indicated in the article above and get an Idea how the world works.

I take that point on board.
Iam not in a position to critisize the proposed technnology the way you put it.
Blind freddy though can see that algae will have nothing to do with it other than as a vehicle to make any operation sound green.
The plant if you can believe anything is "on fire as we speak. Oxyfuel process.
The clean undoubtably refers to the high quality of the finished product.
I just object to being conned.

CO2 capture by algae is a way of using solar energy to convert fossil-derrived CO2 back into fuel. If you have enough solar energy (collector area, greenhouse area, whatever) to convert most of the CO2 back to a fuel, then you have enough solar energy to avoid using the coal in the first place. If you don't have enough solar energy for this, then the technology is "greenwash".

This company is creating a power plant that burns coal, and using a bioreactor, turns the CO2 into 02 and burns the remaining smaller amount of carbon left. If it works it would definitely slow down carbon emissions. Another company is also working on an algae based system that would permanently remove carbon dioxide from the atmosphere through photosynthesis. These are great projects and need to be promoted.
