A new study led by researchers from NASA's Jet Propulsion Laboratory (JPL) and San Diego State University (SDSU) has examined the amount of methane gas escaping from the Arctic – a key component of global warming. The results go against conventional theory, finding that a much larger amount of the gas escapes during the Arctic winter than previously thought.
Although methane is one of the most potent of the greenhouses gases, scientists still aren't entirely clear on all of its ground-based sources. That's why researchers from Sweden's Linköping and Stockholm universities have created a camera that's capable of imaging methane in real time. They say that it could find use in monitoring sources such as sludge deposits, combustion processes, farms and lakes.
Natural gas accounts for over 28 percent of US energy consumption. Its main component, methane, is a widely-used fossil fuel but also a major contributor to rising CO2 levels, and thus climate change. To address this issue, researchers from the Institute of Advanced Sustainability Studies (IASS) and Karlsruhe Institute of Technology (KIT) have developed a process that extracts the energy content of methane, in the form hydrogen, without producing carbon dioxide.
Coffee grounds are not exactly noxious despoilers of the environment,
but many millions of tons of them are generated every year and simply
disposed of with other vegetable matter and food waste. Now, researchers
have devised a way to utilize this innocuous waste product to get rid of a much
more dangerous one. By modifying used coffee grounds into a
carbon capture material, the new product may provide a simple, inexpensive way to
remove a prolific
and harmful greenhouse gas from the atmosphere.
Not content with using hybrid artificial photosynthesis to turn CO2 emissions into plastics and biofuel, researchers at the Lawrence Berkeley National Laboratory (Berkeley Lab) now claim to have produced an enhanced system that uses water and solar energy to generate hydrogen, which is in turn used to produce methane, the main element of natural gas, from carbon dioxide. Generating such gases from a renewable resource may one day help bolster, or even replace, fossil fuel resources extracted from dwindling sub-surface deposits.
