Study concludes that NG leakage higher than reflected in inventories; transportation fuel climate benefits questioned

Green Car Congress

A review of 20 years of technical literature on natural gas (NG) emissions in the United States and Canada comprising more than 200 papers has concluded that official inventories consistently underestimate actual CH 4 emissions due to leakage from the natural gas system. number of devices). number of devices).

Report finds Coal-to-Liquids and Oil Shale pose significant financial and environmental risks to investors

Green Car Congress

Ceres recently released a new report concluding that coal-to-liquid (CTL) and oil shale technologies face significant environmental and financial obstacles—from water constraints, to technological uncertainties to regulatory and market risks—that pose substantial financial risks for investors involved in such projects.

Study finds methane leaks from three large US natural gas fields in line with EPA estimates

Green Car Congress

We are beginning to get a sense of regional variation in methane emissions from natural gas production. If leak rates are too high, natural gas does not compare favorably with one alternative, coal, in terms of climate impact. CIRES is a partnership of NOAA and the University of Colorado Boulder. 0.41% of production.

2022—The Year the Hydrogen Economy Launched?

Cars That Think

Hydrogen produced from renewable energy or nuclear power, with minimal greenhouse-gas emissions, could be piped or transported pretty much anywhere, using mostly existing infrastructure. In short, it could do anything fossil fuels do now, but with substantially reduced climate impact. At the lowest emission rate—0.45

Upper atmosphere facilitates changes that let mercury enter food chain

Green Car Congress

Seth Lyman, now with Utah State University’s Energy Dynamics Laboratory, is lead author of a paper documenting the research published in the journal Nature Geoscience. For example, mercury from coal burning in Asia could rise into the atmosphere and circle the globe several times before it is oxidized, then could come to the surface anywhere.

Stanford launches major new natural gas research initiative

Green Car Congress

US emissions of CO 2 have declined to the level of the mid-1990s. Compared with burning coal, natural gas emits about half the carbon dioxide and substantially less soot, mercury and sulfur. Such fuels could lower greenhouse gas emissions from transportation compared with gasoline and diesel fuel.
