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

Green Car Congress

The amount of methane released into the atmosphere as a result of coal mining is likely approximately 50% higher than previously estimated, according to research presented at the recent annual meeting of the American Geophysical Union. The authors point out that less coal production doesn’t translate to less methane.

8 Rivers announces 8RH2 CO2 Convective Reformer for ultra-low carbon hydrogen production from natural gas

Green Car Congress

8 Rivers Capital announced the development of the 8RH2 CO 2 Convective Reformer—a technology for the production of ultra-low carbon hydrogen from natural gas. The only by-products are liquid water and a stream of high-purity, pipeline-ready CO 2. Clean Power: transformative zero-emissions power cycles.

ANL: life-cycle water consumption of fuel cell vehicles can be cut in half compared to that of conventional ICE vehicles

Green Car Congress

The life-cycle water consumption of fuel cell electric vehicles using hydrogen produced from natural gas with steam methane reforming is almost 50% less than the life-cycle water consumption of conventional internal combustion engine vehicles using gasoline, according to a study by researchers at Argonne National Laboratory (ANL).

Study projects thermoelectric power in Europe and US vulnerable to climate change due to lower summer river flows and higher river water temperatures

Green Car Congress

A study published in Nature Climate Change suggests that thermoelectric power plants (i.e., nuclear and fossil-fueled generating units) in Europe and the United States are vulnerable to climate change due to the combined impacts of lower summer river flows and higher river water temperatures.

Conservation group opposing Thacker Pass lithium mine seeks endangered status for Kings River pyrg (snail)

Green Car Congress

In 2018, Lithium Americas completed a pre-feasibility study (PFS) on a two-phase project with a production capacity designed to reach 60,000 tpa of battery- quality lithium carbonate (Li 2 CO 3 ) and 46-year mine life. The sedimentary-clay deposit at Thacker Pass will use similar mining techniques to many coal deposits.

HYBRIT produces hydrogen-reduced sponge iron on pilot scale

Green Car Congress

The technological breakthrough within the HYBRIT ( earlier post ) initiative cuts about 90% of the emissions in connection with steel production and is a decisive step on the road to fossil-free steel. The production has taken place continuously and with good quality. The potential cannot be underestimated.
