Study finds GHG methane offsets its warming ~30% and precipitation increase ~60% by short-wave absorption

Green Car Congress

(Robert Allen/UCR) Both types of energy—longwave (from Earth) and shortwave (from sun)—escape from the atmosphere more than they are absorbed into it. The atmosphere needs compensation for the escaped energy, which it gets from heat created as water vapor condenses into rain, snow, sleet, or hail. Randles, C.A.

BP awards Colorado State University $5M to research technology for oil recovery from watered-out wells

Green Car Congress

Colorado State University has obtained a 5-year, $5-million grant from BP to study mechanisms involved with technology for oil recovery from “watered-out” wells. Upward of 70% of the petroleum can remain in the rock formations of many watered-out wells. 2000) Water Control. Bill Bailey et al. Oilfield Review.

New study confirms extensive gas leaks in the North Sea; recommends stricter guidelines for handling of abandoned wells

Green Car Congress

Researchers from the GEOMAR Helmholtz Center for Ocean Research Kiel have found that considerable quantities of the greenhouse gas methane escape uncontrolled into the water from abandoned oil and gas wells in the North Sea. On the basis of investigations directly on the seafloor it was possible to determine the amount of escaping gas.

Study finds methane emissions from coal mines ~50% higher than previously thought

Green Car Congress

Kholod said that when a closed mine is flooded, water stops methane from leaking almost completely within about seven years. The study is the first to attempt to account for methane escaping from abandoned mines. Under the same conditions, the amount of methane escaping from working mines would be cut in half.

Duke researchers boost electrolyzer productivity with microfibrous flow-through electrode; 12.5- to 50-times greater than conventional

Green Car Congress

Ben Wiley, a professor of chemistry at Duke University and his team are investigating how nano- and microstructured porous electrodes can improve the productivity of hydrogen generation in a zero-gap, flow-through alkaline water electrolyzer. The water electrolysis performance of the Ni MF felt as a function of the cell potential.

But excess nitrogen is emitted from soils, seeps into groundwater and runs off into surface waters. University of California, Davis researchers will receive $2.8 Wastes from cattle, chickens and other livestock include nitrogen.

MIT Researchers Elucidate Model for Escape of Underground Methane in Frozen Regions; Current Rate of Escape May be Much Faster Than Earlier Believed

gas hydrate accumulations in ocean sediments and permafrost—escapes. Their findings, published online 29 August in the AGU Journal of Geophysical Research , also suggest that methane trapped under the ocean may already be escaping through vents in the sea floor at a much faster rate than previously believed.
