Microgy, which makes and runs facilities that turn manure into natural gas, has started to ship gas from its Huckabay Ridge facility over pipelines.

Six of the eight digesters–large silos that effectively employ heat and microbes to transform the manure into gas–are up and running. When the facility is fully operational, it is expected to be capable of producing 650,000 million cubic feet of gas, or BTUs of heat, a year. That’s the equivalent of 4.6 million gallons of heating oil. (About 1,000 cubic feet of natural gas can produce 1 million BTUs.)

The gas is being bought by the Lower Colorado River Authority, which will also get carbon-trading credits in the transaction.

The shipment, which was delayed, marks another milestone in the pursuit of making alternative sources of energy more mainstream.
