Sesport, "syngas" from coal will used to generate power at the location where the syngas is being generated. This is being considered by coal interests in an attempt to retain their share of the power generation market by sequestraing the CO2 and lowering greenhouse gas emissions. Due to the high cost and other limitations, the technology will be difficult to impliment on a wide scale.

Note - It is really synthetic gas rather than synthetic natural gas.

Thanks, Les, I kind of wondered. It was the first I'd heard of it and will continue to do some reading. I did get the gist about retaining share of power generating market. Looks rather expensive, but do you think that as this is applied and cost factors decrease, that other other plants may adopt this method? Kind of likke having one's own generator for the generator, huh?

Sesport, these type facilities are purpose built and cannot be added to existing power plants. Plus you have to find an underground reservoir to inject the CO2 extracted from the process. I think the cost is going to remain high and will only fly with heavy subsidies. I attached a diagram one example of the process.

Thanks for the diagram, it's printing and I will take a look. (It was difficult to read while balancing the laptop sideways. lol)

So, if the costs are to remain high, it needs heavy subsidies, it can't be added to existing power plants, why are they building it? Seems money could be better spent on new technologies that will have broader application in the future. Or is this the test project for future applications in other countries? I just don't get spending that kind of money if it's application isn't pending for us. I'm going to try to find more, thanks again.

Sesport, construction of these type power plants will be driven my new climate change regulations. The goal is to allow continued use of coal for power generation while greatly reducing the CO2 emissions. This high cost power will be paid by the public thru either higher electricity bills or tax subsidies.

So, I gather that more of them are to be built here in the US? Replacing old plants, I assume, since the technology can't be applied to existing power plants. What will then happen to old plants ... go offline? Thanks for your patience.

Sesport, phased out and scrap metal.

Les - I think I remember reading a discussion you were having re. CO2 injection. I'm having a hard time retracing steps to find it. Could you please point me in the right direction by giving me the discussion title? Thanks, sesport

Sesport, I assume you are referring to the following:

Les - I've looked & looked for that olk topic or related posts (CO2 injection) but can't find it. And I'm sure it's application & impact for LA was mentioned.

I found this, but can't find a publish date. I see dates for references. Do you have any idea what the date of publication is for this link?

Anyway, I'm assuming this is the project & study that is now coming to fruition?

Thanks - sesport

Sesport, I am not sure the date of publication. There are tons of information regarding the CO2 injection and/or sequestration topics. Typically the information falls into the following categories:

1) Power generation with syngas from coal
2) Identification and cost associated with CO2 sequestration in subsurface reservoirs
3) Injection of CO2 for enhanced oil recovery

Okay, Les, I've been going back & forth between this topic and the other, and looking at what I've pulled up, along with EPA information. I don't think we have a power generating facility in this immediate (HS) area, I understand (from other topic) that CO2 injection is being applied in NE LA. Am I correct in concluding, given the cost factor and other information, that there should be no injection sites here in NW LA, in your opinion? Tnanks in advance - sesport
