[Digestion] High costs of biogass plants in Norway

Fri Dec 3 13:49:56 CST 2010

HI Harold,

I wanted to mention that Europe is dominated by insulated tank digesters,
common in Germany, that come at a very high cost.  We have presented
proposals for lagoon digesters that have come in literally 10 times less
expensive than competitive bids for Euro-style systems.  I have done work
with RCM-Digesters International, who specialize in these lagoon digesters,
and have installed them in areas of extreme cold weather.  I am confident
that these will always come in less expensive than the tank-type systems.
The benefit of the tanks often includes the use of less space (more of an
issue in Europe than the U.S.), but that may not be an issue in Norway.  RCM
would be willing to examine a project of this nature if it were more than
just one system.  Let me know if you want me to facilitate.

Best,

Alex
