Biomethane Gas Production

Over 70% of the energy value in a biogas is lost when converting biogas to electrical power. As a result, biomethane has three times the value of electricity selling for $100 per megawatt hour when sold as a renewable transportation fuel,. However current processes used to convert biogas to clean methane gas (biomethane), such as water scrubbing or pressure swing absorption (PSA) are expensive and do not justify cleaning biogas to produce renewable methane gas.

E3's process for producing biomethane utilizes the digester effluent to produce pipeline quality gas economically without the use of any chemical reagents. A low BTU tail gas is not produced and as a result the conversion rates are higher.
