"Controlled release studies are used to develop and qualify measurement methods, however these studies are often performed in an open environment using a single, steady emission source operated across a limited span of flowrates. The Colorado State University (CSU) Methane Emission Technology Evaluation Center (METEC) and the Total Transverse Anomaly Detection Infrastructure (TADI) are industrial measurement platforms which expand the capabilities of controlled release studies. METEC was d...

"Deploying unmanned aerial vehicles (UAV) for methane sensing can provide valuable information on the spatial and temporal variability of methane sources at a level of detail that is not attainable with measurements from traditional stationary monitoring networks. We report on the development of a lightweight, open-path absorption spectrometer for the measurement of atmospheric methane concentration. The spectrometer is based on a single-mode quantum cascade laser (DFB-QCL). The absorption...

"Mitigation of climate change as targeted in the 2015 United Nations Climate Change Conference in Paris (COP21) requires massive reductions of greenhouse gas emissions, far beyond the Intended Nationally Determined Contributions. Natural gas is one of Europe's most important sources of energy, and CH4 emissions are a major contributor to Europe's global warming impact. With a rather short lifetime of 10 years, methane (CH4) is an attractive target for short- and medium-term climate change mit...

"The annual rate of CH4 emissions around the world are significantly smaller than CO2 emissions. The CH4 concentrations in the atmosphere are about 200 times lower than those of CO2, however, methane accounts for more than 25% of global warming. It is important to apply representative measurements that will lead to responsible worldwide estimations of CH4 emissions. The Three main anthropogenic sectors of CH4 emissions (agriculture, energy production and waste) are all characterized by:...

TOTAL and CNRS (1) through the AUSEA (2) project, developed a CO2 & CH4 sensor embarked on drone in the aim at measuring GHG (3) emissions of TOTAL's industrial operation. The sensor is a high-performance multi-gas spectrometer developed by GSMA (4) for monitoring of atmospheric concentration of GHG. Tough challenges are overcome to made it embarked on a drone: weight reduction, perturbation management, soil/air communication. For emission calculation, advanced algorithms have been developed...

Methane emissions are increasingly meaningful in public debates for political, administrative, and public stakeholders and can have significant impact on the future of natural gas. The different approaches for emission estimation in place cause difficulties to identify the methane emissions in the countries correctly and put the gas industry in a difficult situation. The GERG project MEEM (finished in July 2018) developed a methane emission estimation method for the gas distribution grid whic...

Methane is produced during anaerobic digestion in biogas plants. As methane is a very effective greenhouse gas, emissions should be avoided as far as possible, in order to ensure a clean and environmentally friendly operation. The project ""EvEmBi - Evaluation and reduction of methane emission from different biogas plant concepts"" (funded within the 11th ERA-NET bioenergy call) started in April 2018. The project is based on the findings from the previous project ""MetHarmo - European harm...

"Biogas from anaerobic digestion facilities may provide several greenhouse gas mitigation effects including fossil fuel substitution, possible balancing energy source in a supply system with a high proportion of wind and solar power, and reduction of methane emissions from manure management. However, methane losses from biogas plants are problematic, since methane emitted into the atmosphere contributes to global warming, and any losses may thus reduce the environmental benefits of biogas pro...

Atmospheric methane (CH4) has a strong short-term global warming impact and is emitted from a variety of natural and anthropogenic sources. Methane sources include wetlands, landfills, oil / gas / coal extraction activities, and urban emissions from traffic and the natural gas distribution system. Characterizing the magnitude and the origin of these fugitive emissions spatially and temporally is critical to reduce natural gas leakage and to understand their present and future climate impacts....
