The European Union has unveiled its first law addressing methane emissions, known as the EU Methane Regulation, to combat global warming. Methane, a potent greenhouse gas, is a key component of natural gas with a heating potential 84 times greater than carbon dioxide over 20 years. The energy sector is a major contributor to methane emissions. Traditional gas leak detection methods have limitations in sensitivity and accuracy. ABB's new high-sensitivity gas analyzer technology, based on the OA-ICOS principle, offers rapid and precise methane and ethane detection. By employing tunable laser sources and telecommunications-grade near-infrared diode lasers, this technology can detect methane emissions at parts per billion levels with high accuracy. The technology's robustness allows for various deployment methods, including on foot, vehicles, or drones. The availability of such advanced methane detection technologies is crucial in reducing methane emissions and ensuring a healthier environment.
