Manmade methane emissions cause 25% of global heating but also present a golden opportunity to decisively act on the climate crisis. About 40% of these emissions come from leaks from fossil fuel exploration, production and transportation so the measures to plug these leaks could pay for themselves by selling the extra gas captured. To do this however it i...

Our project, Nonlinear Upconversion Technique for Monitoring Environmental Gases (NUTMEG), will develop, construct and test a portable greenhouse-gas sensor for environmental monitoring applications. We will demonstrate a platform approach targeting CO2, Methane, NOx and Ammonia monitoring. Our innovative approach uses laser upconversion in nonlinear (PPL...

Reducing human contributions to global warming and the journey to net-zero is a major problem for society to tackle. Technology developments will be a large part of the process to reduce greenhouse gas emissions. The simplest way to reduce is emissions is to reduce gas leaks, requiring very sensitive leak detection equipment. Natural gas (largely consisti...

For the UK to reach a net-zero carbon economy, the regulation and limitation of greenhouse gas (GHG) emissions needs to rapidly expand. Natural gas is fast becoming our most dominant fossil fuel and industrial leaks are now a leading source of GHG emissions. Industry majors have committed to expanding emissions monitoring, but the technologies currently a...

For the UK to reach a zero-carbon economy, the measurement, regulation, and enforcement of greenhouse gases (GHG) emissions needs to rapidly expand. Natural gas (primarily CH4 methane) remains the dominant fossil fuel and industrial leaks are a leading source of GHGs. Currently there are a lack of surveying methods and equipment for the European Union's (...

To address climate change, attention on greenhouse gases has recently expanded from an overwhelming focus on carbon dioxide to include methane. Methane is the second most important greenhouse gas, because for 20 years after release, it is 84 times more potent than carbon dioxide. Methane is a major constituent of natural gas, which has experienced increas...

The QuEOD project brings together academic and industrial partners to break through the technology barriers for novel types of time-resolved SWIR detectors and pave the way forwards for UK sovereign supply and leadership. It will to develop a unique supply chain and engage in commercial exploitation for both CMT and GaSb detector technologies for next gen...

As natural gas becomes the leading fossil fuel, industrial gas leaks are becoming a major source of climate changing carbon emissions. The SPLICE project assembles a world-leading scientific and industrial consortium to develop and industrialise gas (methane) imagers based on time-correlated single photon counting, one of the early applications of quantum...

"QLM is developing compact, high-sensitivity, low-power, Tuneable Diode Lidar (TDLidar) gas detection and imaging systems based on novel semiconductor infrared lasers and detectors and quantum technology developed by researchers at the University of Bristol. By providing far more cost effective and practical methods to identify and quantify leaks in gas p...

Natural gas is expected to continue to increase its role as a major global energy source for decades to come. But, while natural gas combustion is cleaner and more efficient than other fossil fuels, methane, the primary constituent of natural gas, is 30 times more potent than CO2 as a greenhouse gas, so leakage in production and transportation can overwri...
