Renewable Natural Gas (RNG), also known as biomethane, biogas, or renewable methane, is an increasingly important part of the U.S. clean energy future. When it comes to sampling, RNG comes with complex challenges. The biogas experts at Alliance Technical Group are not only here to help you understand your RNG sampling and analysis requirements, but to also help you develop solutions.
What are the challenges?
The biogas must meet gas tariff requirements to be considered pipeline quality.
To meet the pipeline’s specifications, the product gas and other sample points are routinely sampled and analyzed.
Initial testing requirements for the biomethane can be rigorous and complex.
Moisture can cause serious issues—onsite testing requires specialized equipment.

How Alliance’s experts can help
We work with the waste facility and pipeline company to help interpret the sampling and analysis requirements.
Our analysis capabilities can meet specialized, onsite needs-for example water dew point, hydrocarbon dew point, and moisture content (lbs/MMscf).
We can help determine if a comprehensive baseline test is required or if a less expensive and demanding test plan will satisfy the gas company.
Our experts will handle all the sampling needs efficiently in 1-2 days.
We can oversee the entire process from start to finish including the sampling, laboratory analysis, and interpretation of results.
Subsequent testing may be required after the first baseline test comes back. Alliance can help develop a regular test plan and sampling event calendar, so the client doesn’t have to.
