While the German market for the upgrade and feed-in of biogas<br />

is relatively young, the technologies for this special gas application<br />

have been in use already for decades in other European<br />

countries. according to recent research by the Fraunhofer<br />

Institute for Wind Energy and Energy system Technology, more<br />

than 90 biomethane plants ore operating all over Europe. out<br />

of these, according to the information available to the German<br />

Energy agency, 53 feed biogas upgraded to local natural gas<br />

quality into the grid by mid 2010.<br />

regarding the total number of projects realized so far, pressure<br />

swing adsorption and pressurized water scrubbing technologies<br />

are dominating the European market [see figure]. In<br />

full-scale applications, physical adsorption technologies (with<br />

organic dissolvers) so far have been installed only in Germany<br />

and switzerland. Chemical adsorption technologies (with<br />

organic dissolvers) have been applied only in Germany, sweden<br />

and switzerland. Membrane applications so far have been used<br />

only in austria and the netherlands.
