[Gasification] what does PO stand for?

[ktwu at itri.org.tw]

Dear List

In Dr Richard L. Bain's presentation "Biomass Gasification R&D Activities in North America" at IEA Task 33 Meeting, Pitea, Sweden (Oct 19, 2011),

http://128.131.132.12/app/webroot/files/file/minutes_and_presentations/Pitea_Oct2011/Workshop/R_Bain_Gasification_in_N_America.pdf

there is a table about "U.S. Biomass Gasifier Developers" (p. 13). In the table, what does the "PO" stand for in "Status" coulmn? Could anyone tell me the meaning? Thanks.

Thank you very much for your kind assistance indeed.

Best wishes

KT
