      It is a shame they are allowed to burn off so much Natural Gas at the Bakken oil fields. The sat photo shows it compared to major cities at night.

        They have so much of it that they don't know what to do with it all. They've run out of room to store it.

          Why don't they run generators and put it on the grid? Better than just burning it off!

            A lot of our utility power in the US is generated by burning natural gas. Coal is used more though, and they should use more natural gas instead.

              Sewage to methane process to undergo full scale testing in 2017 and will be ready to scale up for putting methane back at pipeline quality according to testing at Argonne.

                  I attended a bio-fuels meeting at the UW Green Bay last Monday. At the meeting the final speaker approached the EPA regulations. There are so many restrictions laid forth by the EPA with the RFS and RINs it is taking several projects over a year to get permits. The speaker stated that she was only brushing the surface of the regulations to keep the topic within the time frame. (1 hour)

                    University of California Riverside now hosts a center for applied research into renewable natural gas. It is funded in part by SoCalGas with a matching donation from the South Coast Air Quality Management District (SCAQMD) and the National Center for Sustainable Transportation (NCST):

                      Stahlbush Island Farms, Corvallis, OR, is an environmentally friendly farm and food processor recognized nationally for its sustainable production of fruits, vegetables, grains and legumes.

                      Stahlbush operates a first-of-its-kind (in North America) Biogas Plant that turns all of the farm agricultural byproducts (corn husks, silage, waste fruits and vegetables, etc.) into electricity. Begun in 2008, the $10M project took 14 months to complete before becoming operational in 2009. Methane from the process powers a 20-cylinder, 2,200hp Caterpillar engine that generates twice as much electricity as Stahlbush Island can consume.

                      It took several growing seasons to completely optimize the digester, explained John Bailey, who says there is a steep learning curve early on for anaerobic digestion (AD). Our digester consumes everything from our corn stalks to blueberries. The continual variations in feedstock create a myriad of challenges for the operators who strive to maximize daily kW output. The engine coolant provides the heat for blanching vegetables before they are frozen. And the engine exhaust passes through a heat exchanger for use in the facility. In the long term, the methane may eventually find a use for farm equipment and trucks.
