We anaerobic digestion capacity increases slowly

There are two state programs to encourage farmers to install methane digesters, which capture methane gas that can be converted into electricity. Despite these efforts, farmers in Minnesota have been slow to adopt this technology.

This reluctance may be due largely to high initial costs and low electricity purchase rates offered by utilities. Technical limitations of biogas can also be a factor. Studies have indicated that the biogas production profitable in Minnesota using the technology during digestion may be limited to large dairy farms (at least 300 cows) that collect by scraping manure rather that rinsing. methane production cost, it takes a significant amount of manure gernated farm, and cows have been shown to have a greater potential for gas production as pigs or poultry (measured in units of ft.3/animal / day).

A methane digester is reported the new project from Green Meadow Farms. They produce methane and sell methane gas to a company called North American Biofuels LLC They take the gas and convert it to electricity. The manure will now be diverted into the digester before it enters Mill. By doing this, they must also be able to reduce the cost of ferric chloride they use in the treatment process.

Straus Creamery expects to generate up to 600,000 kilowatt hours per year, saving an estimated 6,000 in energy costs per month. A digester is a sealed container that uses bacteria to decompose the manure. As part of this process, methane is produced and used to fuel electric generators.

Progress is underway, but more dynamic is needed for the sector will make a significant contribution to emissions of greenhouse gases in the next 10 years. biogas digesters will not appeal to everyone. Biogas is one of questions where the results do not come immediately. It may take several weeks to process changes to take effect, if the changes are more difficult to control in the processing plant other, but they do come.

A large and still barely exploited in the United States, is the use Biogas is replacing natural gas in our gas systems in the world. Biogas must be clean before it can be pumped into this system to achieve demanding distribution of natural gas pipeline quality standards. It takes good composition calorific value for the network of local distribution accept. Carbon dioxide, water, hydrogen sulfide and particulates must all be removed if it is present.

The biogas is a mature technology, well established in many European countries. Experience in Sweden has shown that biogas upgraded to be used as transport fuel, while a relatively new technology that can be done with high reliability and at a reasonable cost. Same the mud that comes at the end makes an excellent fertilizer.

In the United States concerns still exist on the production of biogas during the winter expensive means of collecting manure, manure handling systems failure and the absence of external financial assistance. This is even some of the constraints identified in the promotion of the program. About the Author
