Gas Technology Institute (GTI), Des Plaines, Ill., is publicizing a report titled Guidance Document for the Introduction of Landfill-Derived Renewable Gas into Natural Gas Pipelines.

According to the report, the integration of renewable gas from non-traditional sources can provide significant benefits, including cost-effectively reducing greenhouse gas emissions and increasing available resources. An initiative launched by GTI is establishing parameters for evaluating the suitability of biomethane products—derived from dairy waste and landfills—for safe and proper introduction into existing natural gas pipelines and to assure compatibility with existing supplies.

Sponsored by the natural gas industry, the U.S. Department of Transportation (DOT) and members of the Solid Waste Association of North America (SWANA), these projects have been adding to the industry's understanding of the chemical and biological composition of renewable gas.

The newly released Landfill Guidance Document provides analytical and other key information to pipeline companies and natural gas local distribution companies (LDCs) so that parameters specific to clean biomethane can be identified to support a productive discussion between these parties and the suppliers for contract development.

The document includes a list of constituents and methodology for testing, as well as statistical analysis of the acquired data. It provides information about specific instrumentation for identifying and monitoring trace constituents, and cleanup technologies for removing them.

Previously, under the sponsorship of a consortium of gas companies, including Operations Technology Development (OTD)—and working with a number of universities and dairy farms throughout the United States —GTI scientists developed the first national biogas guidance document for introducing methane from dairy waste into existing pipelines, entitled Pipeline Quality Biomethane: North American Guidance Document for Interchangeability of Dairy Waste Derived Biomethane.

Says Kristine Wiley, project manager says, "GTI is exploring alternative and renewable energy resources that can integrate with the U.S. energy distribution network and support the expansion of the nation's energy supply. Evaluating and mitigating the effects of new fuels on the delivery infrastructure is a critical aspect to enable the use of this renewable resource."
