What I typed at the first go in my post in anyway irrelevant since they are using fermentation of biomass (as quoted by the mentioned website).
But hey, your photo again brings the first part of my post to relevance!
If you read what is written under "Blue crude", it says: CO, H2 and H2O is created from CO2 and H2; syngas (consisting of CO and H2) reacts to form liquid energy carrier (blue crude) comparable with crude oil.
This is exactly what happens in a gas to liquid plant.
You know, I get a feeling that this is all hokum/sham for funding and marketing purpose. Some places they are talking about converting biomass to butane. Other places they are basically re-inventing the wheel by citing Gas to liquid technology.
The only thing different from normal GTL is that they are invoking the politically correct nuances of environment friendly terms like "ecological power generation" for hydrogen production (in GTL process this happens via steam reforming of carbon/hydrocarbon fuel http://en.wikipedia.org/wiki/Steam_reforming), and "direct air capturing" (not required in GTL, since you anyway get CO, CO2 from steam reforming).

Besides fermentation, there is one more biological process (culture based) to extract the methane from the pressmud (the residue in the filters, after filtering the sugarcane juice). This methabe is hence called bio CNG. This too is a slow process; the process parameters and dynamics are not yet fully understood AFAIK. |
That's what even I suspect. The process will be very slow.
If I am not wrong, what you are talking about as bioCNG is nothing but the same ol' biogas (Gobar gas in India) but purified and compressed?
