RWE Innogy Announces Biogas Plant Project to Feed Into Natural Gas Network
the following Anaerobic Digestion Plant is among several announced by RWE, most of which are biomass power type plants.
By Anna Austin
RWE Innogy UK, an energy company which plans, builds and operates renewable power generation facilities in the United Kingdom and Continental Europe, recently announced two separate European power plant ventures.
On Sept. 25, RWE Innogy released plans to build a 6.5 megawatt thermal capacity biogas power plant in the municipality of Güterglück at Saxony-Anhalt, Germany. Contracted by Gelsenkirchen, Germany-based Hese Biogas GmbH, a Schmack Biogas group company, the plant will run on feedstock acquired through regional farmers.
Construction is planned to commence in October and completion is expected to be achieved in the summer of 2009. Fritz Vahrenholt, chief executive officer of RWE Innogy, said the company’s goal is to increase biogas activities in Germany, and build another 10 similar plants by 2012.
The plant’s biogas product, which will be fed into the local natural gas network upon meeting natural gas specifications, will be marketed by RWE’s sales subsidiary, RWE Energy.

I'm in the process of reviewing several different Anaerobic Technologies and would like for you to review the statement figures I'm putting in this blog and from the artical Biomethane Gas is very valuable.
1000 ton mixed waste/day x 60% *biosolids = 600 ton vs/day x 2000 **= 1,200,000 lb vs/day
X 18*** x 0.6**** = 12,964,000 ft3 CH4/day x 960 Btu/ft3 = 12,500,000,000 Btu/day
- Process Heat (2,000,000 lb x 35***** x 9/5****** x 30%******* = 37,800,000 Btu/day) =12,462,000,000 Btu/day Net
BIOMETHANE Sells for $10/million Btu = $124,620/day
*This is an educated estimate that is based upon what we know and what other people have reported.
**Here I am using English not metric tons which would be 2200 pounds/ton.
***18 cubic feet of biogas generated per pound of volatile solids (VS) destroyed. This is the high end figure. Another educated guess. You will see that we use 12 for the worst case. This is the big bugaboo of the industry, i.e., everyone has a different claim and it is very hard to measure on a macro scale.
****60 to 65% of biogas is methane.
*****Asuming that our feedstock comes in at a temperature of 20 degrees Celcius and must be raised 35 degrees to 55 degrees C for thermophillic operation.
******9/5 is the ratio of Fahrenheit to Celsius. And we know that it takes One Btu to raise one pound of water one degree F.
*******There is 70% heat recovery in the VRAD(c) Process.
$124,620 per day sales at the 18 ft3 production rate.
Therefore $124,620/18 x 12 = $83,079 sales per day worst case. Remember what I said about the bugaboo of the industry.
Now, I haven't the slightest idea what electricity is worth in Korea but if you go to your CRC you will find that there are 3413 Btu per kWh. So going back to our Btu figures 12,462,000,000/3413 = 3,651,333 kWh/day x 70% nominal conversion loss = 2,555,933 kWh per day net.

Globalhome - It is good to receive comments on this blog.
However, I would suggest that this may receive a better opportunity of a reply from an expert if you would post it to our Forum at the Anaerobic Digestion Forum.
Another one, possibly even better, for getting good response from AD experts is Friends of Biogas.
