Renewable Natural Gas – A Clean Energy Resource
Reducing our Country’s Reliance on Fossil Fuels
Moving us closer to Energy Independence
Although Carbon Dioxide is a widely recognized greenhouse gas, Methane is a considerably more potent heat-trapping gas. According to the Environmental Protection Agency’s (EPA) Landfill Methane Outreach program (LMOP), landfills are the third largest human-made source of methane. Over 630 landfills in 48 states are using landfill methane to generate electricity instead of flaring the landfill gas, which greatly reduces atmospheric emissions. This same renewable landfill biomethane can also be cleaned of its moisture, carbon dioxide, nitrogen, hydrogen sulfide, siloxanes and other trace impurities and injected into a local or interstate gas pipeline.
Renewable Natural Gas (RNG) is an ultra-clean, low-carbon natural gas alternative. As organic waste biologically decomposes, it emits methane gas or biogas, which is primarily a mixture of methane gas and carbon dioxide. RNG or biomethane that is upgraded (cleaned) to pipeline-quality natural gas may be blended, or substituted for, geological natural gas.
Today’s rapidly growing just-in-time products and goods delivery market has propelled heavy-duty vehicles into the fasting growing segment of the United States transportation sector in terms of energy use and vehicle emissions. According to NGV America (Natural Gas Vehicles of America), although heavy-duty vehicles total only 7% of vehicles on America’s roadways, they account for 50% of all smog-precursor emissions, 20% of all transportation-related greenhouse gases and consume over 25 billion gallons of fuel per year. Additionally, over 35% of Americans reside in areas of exceedingly poor air quality and 40% of our population is regularly exposed to unhealthy levels of ozone and particulate matter. This situation has resulted in the migration of transport vehicles to cleaner-burning fuels, which has been gaining widespread support in North America at both the federal and state levels. The California Air Resource Board (CARB) has published that a natural gas vehicle fueled with fossil natural gas emits 27% less greenhouse gas than a comparable gasoline or diesel-fueled vehicle and costs less per mile to operate. Wen RNG is used instead of fossil natural gas, emissions are reduced 70% in standard transport vehicles and up to 90% in new, high-performance heavy-duty truck engines.
WRH Biogas™, part of WRH Group™, is dedicated to the research, development, construction, ownership, and operation of landfill and anaerobic digester renewable natural gas (RNG) plants in the Western United States. WRH Biogas’™ research and development efforts are focused on Landfill Gas Optimization and Digester Gas Boost Control, to significantly increase RNG yield, while also stabilizing long-term production.
WRH Biogas™ and WRH Power Systems™ work together during project planning, design, engineering and construction often exploiting the optionality at the Landfill and Digester sites. Frequently land is available for blending other renewables such as solar, wind, battery and storage with conventional thermal generation for continuous, dispatchable renewable-based power generation at or near our RNG sites.
