As the Des Plaines, Ill.-association notes, integrating renewable gas from non-traditional sources can provide benefits to processors, including cost-effectively reducing greenhouse gas emissions and increasing available resources.
An initiative launched by GTI establishes 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 ensure 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, these projects add to industry's understanding of the chemical and biological composition of renewable gas.
The 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. 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.
Says Kristine Wiley, project manager, “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.”
