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....

Methane emissions are responsible for about 25% of current global warming and the oil and gas sector is one of the largest anthropogenic sources of methane. The IPCC, in its “Special Report on Global Warming of 1.5 degrees”, noted that emissions of Short-Lived Climate Pollutants like methane and black carbon need to be reduced by 35% or more by 2050 to stay below the 1.5 degrees target, while the International Energy Agency identified upstream methane emissions as one of the most importan...

If you're looking for professional advice on methane analysis by means of open-path laser analysers or a mid-infrared tunable-diode laser spectroscope, follow the links for the relevant e-Learnings. Similarly, if you're in need of an overview of new sensor technologies for methane analysis, watch a presentation on the topic delivered by Professor Daniel Zimmerle of Colorado State University. Numerous applications from defense to geology use thermal infrared (TIR) hyperspectral sens...

With growing concerns regarding climate change in the scientific, political and public spheres, there is mounting pressure on businesses to provide accountability for their impacts on the environment. The recently published IPCC report highlighted reductions in methane emissions as a central factor in keeping global warming below the critical threshold of 1.5 oC above pre-industrial temperatures. Hence, industrial activities associated with fugitive emissions of methane may well be under incr...

It is of increasing importance to fully validate the performance of methane detection and measurement technologies that are to be used in Leak Detection and Repair (LDAR) programs and for the traceable accounting of methane emissions. Subjecting technologies to trials involving controlled gas releases can yield key data supporting a particular methods ability to detect and quantify emissions, but only if the evaluation is carried out with an appreciation of the limits of the test method itsel...

Optical gas imaging (OGI) has traditionally been a qualitative technology. Recent advancements in the technology are moving OGI towards quantitative methods. New quantitative features in the FLIR GF series cameras and QL320 tablet provide a much more efficient user experience and remove much of the uncertainty related to OGI surveys and resulting quantification of emissions. FLIR's new Q-mode captures radiometric OGI data, along with meta data provided by the user, into a single file forma...

Similarly, for a broader perspective on the identification and validation of methane sources, follow the link. Methane escape from natural gas distribution systems results not only in global warming, but also in economic loss. An estimate from the Boston region implies a financial damage of $90 million as about 15 billion cubic feet of natural gas escape from the distribution...

As known European natural gas resources is declining and the EU is depending increasingly on imported natural gas. Consequently, diversification of the European natural gas supply has become necessary and this is being implemented as required by the Renewable Energy Directive 2009/28/EC. Under mandate M/475, CEN/PC 408 developed specifications for biomethane (i.e. EN16723-1 for injection into natural gas grids and EN16723-2 for transport fuel). Currently, the test methods cited in EN16723 are...

Biomethane is an important source of green and renewable energy. To allow injection of biomethane into the natural gas grid or the use as a vehicle fuel, it should meets the quality standards for natural gas. The timely and accurate measurement of the biomethane energy is of fundamental importance for users and distributors. The MicroGC technology supply features ideal for fast and accurate on-line analysis of biomethane and calorific value measurements. Minor organic contaminants like hyd...
