UrduWhile peatlands have historically stored massive amounts of soil carbon, warming is expected to enhance decomposition, leading to a positive climate change feedback effect. This study experimentally warmed peatlands in northern Minnesota and observed increased methane production relative to carbon dioxide release. This methane release process is likely to amplify global climate warming.

The study was headed by Professor Claudia Kemfert from the German Institute for Economic Research (DIW) and Leuphana University Lüneburg in collaboration with Franziska Hoffart from Ruhr-Universität Bochum, Fabian Präger from Technische Universität Berlin and Isabell Braunger and Hanna Brauers from the University of Flensburg.
Converting Methane to Methanol—With and Without Water
Adding water to the catalytic reaction that converts methane into useful methanol makes the process more effective, but it creates challenges for industry due to steam from the water. Now scientists have identified a common industrial catalyst, copper-zinc oxide, that completes the conversion along different pathways depending on whether water is present or not. This could potentially keep methane, a potent greenhouse gas, out of Earth’s atmosphere and instead turn it into useful products.
Converting Methane to Methanol — With and Without Water
UPTON, NY — Chemists have been searching for efficient catalysts to convert methane — a major component of abundant natural gas — into methanol, an easily transported liquid fuel and building block for making other valuable chemicals. Adding water to the reaction can address certain challenges, but it also complicates the process.

Mapping methane sources in Paris
Researchers reporting in ACS’ Environmental Science & Technology have conducted mobile measurements of methane and its sources throughout Paris. Their findings suggest that the natural gas distribution network, the sewage system and furnaces of buildings are ideal targets for methane reduction efforts.
Solar energy from the deep repository
During the winter months, renewable energy is in short supply throughout Europe. An international project is now considering an unconventional solution: Renewable hydrogen and carbon dioxide are pumped into the ground together, where naturally occurring microorganisms convert the two substances into methane, the main component of natural gas.
Saving the climate with solar fuel
Produced in a sustainable way, synthetic fuels contribute to switching mobility to renewable energy and to achieving the climate goals in road traffic. In the mobility demonstrator “move” Empa researchers are investigating the production of synthetic methane from an energy, technical and economic perspective – a project with global potential.
Mitigating emissions in the livestock production sector
A new study shows that emission intensity per unit of animal protein produced has decreased globally over the past two decades due to greater production efficiency, raising questions around the extent to which methane emissions will change in the future and how we can better manage their negative impacts.
Finding fire and ice: Modeling the probability of methane hydrate deposits on the seafloor
A team of researchers from Sandia National Laboratories and the U.S. Naval Research Laboratory have developed a new system to model the likelihood of finding methane hydrate and methane gas that was tested in a region of seafloor off the coast of North Carolina. This test was published on March 14 in the scientific journal Geochemistry, Geophysics, Geosystems.

Researchers at the University of Illinois Chicago have discovered a way to convert the methane in natural gas into liquid methanol at room temperature.
Methane Emissions from Coal Mines Are Higher Than Previously Thought
Methane emissions from coal mining are likely much higher than previously calculated, according to new research. That’s due mainly to emissions from abandoned mines and higher methane content in deep coal seams.
Rutgers Legal Expert Available to Discuss Environmental, Climate Change Priorities
New Brunswick, N.J. (Jan. 21, 2021) – Rutgers University Professor Cymie R. Payne, an expert on United States and international environmental laws, is available for interviews on how the administration of President Biden can strengthen laws and regulations and efforts to…
Symbionts of Methane Eating Microbes Fix Nitrogen
Sediments on the ocean floor contain large amounts of methane. Two groups of microbes work together in symbiosis to break down this methane in oxygen-deprived sediments. New research shows that both groups can fix nitrogen to satisfy their need for nutrients from methane. This helps the microbes hedge against changes in their environment.

‘Blinking” Crystals May Convert CO2 into Fuels
Imagine tiny crystals that “blink” like fireflies and can convert carbon dioxide, a key cause of climate change, into fuels. A Rutgers-led team has created ultra-small titanium dioxide crystals that exhibit unusual “blinking” behavior and may help to produce methane and other fuels, according to a study in the journal Angewandte Chemie. The crystals, also known as nanoparticles, stay charged for a long time and could benefit efforts to develop quantum computers.
