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)...
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,...
A gas turbine engine (also known as a combustion turbine engine) operates on the Brayton Cycle, which is the same thermodynamic cycle that a microturbine engine operates on, but the capacity of a gas turbine engine is larger, ranging...
Burning off biogas produced as a byproduct of activities (e.g. on landfills) by flaring it rather than recovering the biogas for use as a source of energy is one way of getting rid of methane and volatile organic carbons...
Environmental & Economic Impacts of Biogas Combustion in Piston/Reciprocating Engines Reciprocating internal combustion engines, or piston engines, are used worldwide as a low-cost method of generating power. Reciprocating combustion engines have also been widely used to generate power from...
Biogas produced from the anaerobic digestion of organic waste offers a valuable source of renewable energy. Considering the abundance of organic waste produced by various human activities, this could provide a significant source of renewable energy that is completely sustainable...
While incentives and policies that promote the use of renewable natural gas for thermal applications by end-users are currently limited, some local and state voluntary programs are beginning to emerge. Additionally, the demand for renewable natural gas is increasing as...
While the price of electricity is currently relatively low and is expected to stay that way in the foreseeable future, some renewable portfolio standard (RPS) programs issue renewable energy certificates that promote the use of renewable natural gas derived from...
A change in policy that can help RNG project developers overcome some of the common challenges faced when new projects are being developed is the introduction of incentives for pipeline interconnection together with clear quality guidelines required for biogas that...
