Monash study on solar-driven electrolysis for green hydrogen production cautions on life-cycle emissions and EROI

Green Car Congress

Researchers at Monash University in Australia have conducted a lifecycle analysis and net energy analysis (LCA/NEA) of a hypothetical large-scale solar-electrolysis plant for the production of green hydrogen. The open-access paper on the study is published in the RSC journal Energy & Environmental Science. Palmer et al.

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

Green Car Congress

A new study by researchers from the University of California, Riverside and colleagues in the US and Europe has now found that methane short-wave absorption counteracts ~30% of the surface warming associated with its long-wave radiative effects. This in turn reduces the amount of water that evaporates.

Study finds climate impact of hydropower varies widely

Green Car Congress

earlier post ), a new study by a team at Environmental Defense Fund finds that the climate impact of hydropower facilities varies widely throughout the world and over time, with some facilities emitting more greenhouse gases than those burning fossil fuels. They also estimated emissions caused by flooding the reservoir.

A New Energy-Efficient Hydrogel Pulls Water From Air

Cars That Think

Using a new kind of hydrogel material, researchers at the University of Texas at Austin have pulled water out of thin air at temperatures low enough to be achieved with sunlight. Atmospheric water harvesting draws water from humidity in the air. The material is a hydrogel, a polymer network that naturally retains a lot of water.

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 measures the effect of regional change in clouds caused by ships’ emissions; masking GHG warming

Green Car Congress

Satellite data over a shipping lane in the south Atlantic show that the ships modify clouds to block an additional 2 Watts of solar energy, on average, from reaching each square meter of ocean surface near the shipping lane. The open-access study was published in AGU Advances, a journal of the American Geophysical Union.

Study Finds Stratospheric Water Vapor Is An Important Driver of Decadal Global Surface Climate Change

Green Car Congress

Decadal warming rates arising from (i) greenhouse gases and aerosols alone (black); (ii) that obtained including the stratospheric water decline after 2000 (red); and (iii) including both the stratospheric water vapor decline after 2000 and the increase in the 1980s and 1990s (cyan).
