- Comments Off on Siloxanes from Household Products can be a Bane or a Boon for Landfill Gas Producers
Synthetic man-made compounds that are used to manufacture common household products such as motor oil and shampoo are ending up on landfills where they supercharge natural gas produced by those landfills, a new study has found. While this currently poses a problem, it could present an opportunity to make landfill gas more energy-rich in […]

- Comments Off on Environmental & Economic Impacts of Compressing RNG for use as CNG Vehicle Fuel
Biogas can have impurities removed and upgraded to render it suitable for use as a vehicle fuel. This analysis examines the environmental and economic costs associated with cleaning, upgrading, and compressing RNG for use as compressed natural gas (CNG) used to power vehicles, using a Unisons Solutions biogas CNG (BioCNG) upgrading system and fueling […]

- Comments Off on Upgrading Biogas for Pipeline Injection: What are the Environmental and Economic Costs?
Biogas can be cleaned to improve the quality, and once upgraded, it can be injected into a natural gas pipeline. In order for the raw biogas to meet quality standards required by pipeline operators contaminants such as sulfur, siloxane, and water vapor need to be removed. The methane component is then separated from the […]

- Comments Off on Energy Conversion via a Biogas Fuel Cell: What are the environmental & economic costs?
A biogas fuel cell produces direct current electricity via an electrochemical process as opposed to combustion that drives a mechanical process that drives an electrical generator to produce power. This electrochemical process produces much lower criteria pollutant emissions, and even no emissions in some cases. Stationary biogas fuel cells are typically the high-temperature internal […]

- Comments Off on Environmental & Economic Impacts of Combusting Biogas in Microturbine Engines
Microturbine engines are smaller versions of gas turbine engines ranging from 30 kilowatt to 333 kilowatt for individual engines to several megawatts when multiple engines are combined. The efficiency of converting biogas to electricity ranges from around 22-27%. Nitrogen oxide emissions from microturbine engines powered by biogas fuel typically tend to be less than […]
