[Gasification] Gasification and Water Injection into producergas

[Jesse Klinkhamer]

Hi All,
 
I would be keen to learn some more myself actually. I know bit and bobs
worth of info on the algae Biodiesel program but nothing substantial. I too
would like to know more about the economics and viability and so on. So far
everything I have heard though sounds very promising.
 
Jesse

Unfortunately I don't. I run a very small scale biodiesel operation myself,
so I contacted the company out of interest to find out more, only I haven't
received any replies. I imagine that they are keeping everything quiet until
they get their plant going on a commercial basis.

Dear Jesse and/or Peter

Very interesting!!

As I understand it, some algae can contain as much as about 30% fats. 
However, it costs a lot to recover and dry the algae.

Would you have some approximate idea of the cost of biodiesel produced from
algae?

Best wishes,

Kevin
