Nevadanano Mps Methane Gas Sensor

NevadaNano’s MPSTM Extended Range and Extended Range Low Power Methane Gas Sensor is designed and optimized for open-air detection of methane and natural gas plumes over a full range of concentrations, from 50 to 1,000,000 ppm. In field testing, the sensor has detected methane emitted at a rate of 2 standard cubic feet per hour (SCFH) or 0.1 kg/hr at distances up to 10 meters with nominal false positive readings over weeks of outdoor operation.

The smart sensor is intrinsically safe (FM class 1, div 1 / ATEX zone 0), robust, and extremely poison-resistant. It has built-in environmental compensation and performs constant self-testing for fail-safe operation. Sensor readings are output on a standard digital bus— no added electronics are required. With no field calibration required, the MPS Extended Range Low Power Methane Gas Sensor delivers industry-leading performance and a low cost of ownership.

    Methane Leak Detection

    Natural Gas

    The production of natural gas is at all-time highs since 2005. While the burning of natural gas for power and heat produces fewer carbon emissions than coal, the natural gas supply chain is prone to leaks. A massive 2018 study* coordinated by the Environmental Defense Fund (EDF) and published in the journal, Science, estimates that natural gas operations leak 2.3% of the total gas extracted. For every hundred cubic feet of natural gas that comes from underground reservoirs, consequently 2.3 cubic feet is put into the atmosphere. The leaks vary in severity and are widespread.

    This is a serious problem that IoT infrastructure companies have been trying to solve. Natural gas consists almost entirely of methane, a highly potent greenhouse gas. It has more than 80 times the climate-warming impact of carbon dioxide in the 20 years following its release. Methane emissions account for about 25% of the warming experienced today.

    The Solution to Methane Gas Leaks

    People often overlook the climate benefits of cleaner-burning natural gas because so much of it leaks.

    Leaks also mean lost product—to the tune of at least $30 billion each year. The only way to mitigate these leaks is to detect them. Current ‘fence-line’ methane gas detection systems, like open-path lasers, are bulky and prohibitively expensive to deploy. Such technologies do not lend themselves to leak localization. (Using them as such is akin to determining which room in a massive apartment building is on fire by measuring how much smoke blows across the property line.)

    To truly locate methane leaks across the entire supply chain, there needs to be a new sensing paradigm: low-cost, real-time sensor networks. The MPS Methane Gas Sensor utilizes cloud-based, 24/7 monitoring with an array of sensors mounted near potential leak points can enable early methane leak detection and rapid localization. Infrastructure companies have noticed that IoT connected, cloud enabled sensor networks are the best way to achieve fast mitigation times, thus reducing the amount of methane lost into the atmosphere (and from the bottom line).

    Methane Gas Detection 

    NevadaNano’s new MPS Methane Gas Sensor is the first completely innovative technology for methane gas leak detection in over 40 years. The key shortcomings of existing sensing technologies are no longer a worry due to the NevadaNano sensors. The MPS is a robust Microelectromechanical-system (MEMS) platform that is inherently low-power, poison and drift-resistant to enable calibration intervals that can be measured in years. Built-in environmental compensation is crucial because it delivers reliable, accurate performance across a range of harsh conditions, from -40C to 75C and 5% to 95% relative humidity.
