2023年1月17日 · Avoiding the worst impacts of climate change may require removing methane from industrial emissions streams and the atmosphere — but researchers are so far stymied on how to capture the potent...

2023年11月28日 · We already have strategies for cutting methane emissions — fixing natural gas leaks (methane is the main component of natural gas), phasing out coal (mining operations release methane),...

3 天之前 · Last year was the hottest on record, and scientists are clear that the world is on track to exceed 1.5 degrees C (2.7 degrees F) of global warming. Methane, a potent greenhouse gas (GHG), is a significant and growing part of this problem. It is the second-most impactful GHG after carbon dioxide (CO2) and, even though there is much less methane than CO2 in the …

Methane can strongly absorb infra-red radiation at 3.3 and 7.7 µm wavelengths, generating a higher radiative forcing (Dean et al., 2018). Thus, a potential way for reducing the effect of global warming is to capture methane from biogenic sources like anaerobic digestion plants and landfills and use it as a fuel (Dlugokencky Edward et al., 2011 ...

2023年10月20日 · Oil producers burn excess methane to convert it to less potent carbon dioxide in a process known as flaring. Malfunctioning flares can allow excess methane to seep into the atmosphere.

2021年9月30日 · But first, we need effective methane capture technologies. Researchers have developed a handful of techniques, such as the use of special catalysts or microbes to oxidize methane and convert it into CO 2 or methanol for industrial use.

2022年4月12日 · Methane accounts for 16−20% of global greenhouse-gas emissions, and is more potent at trapping heat in the atmosphere than carbon dioxide (see Nature 596, 461; 2021). More than half of methane...
