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.

Harvard team finds large-scale US wind power would cause warming that would take roughly a century to offset

Green Car Congress

Extracting energy from the wind causes climatic impacts that are small compared to current projections of 21 st century warming, but large compared to the effect of reducing US electricity emissions to zero with solar. They find that large-scale wind power generation would warm the Continental United States 0.24

ICCT LCA study finds only battery and hydrogen fuel-cell EVs have potential to be very low-GHG passenger vehicle pathways

Green Car Congress

In addition to its regional and temporal scope, this study is distinct from earlier LCA literature in four key aspects: This study considers the lifetime average carbon intensity of the fuel and electricity mixes, including biofuels and biogas. This results in significantly lower battery production emissions than in earlier studies.

NREL researchers use adversarial training to super-resolve climate data; up to 50X higher resolution data

Green Car Congress

Researchers at the US Department of Energy’s (DOE’s) National Renewable Energy Laboratory (NREL) have developed a novel machine learning approach quickly to enhance the resolution of wind velocity data by 50 times and solar irradiance data by 25 times—an enhancement that had yet to be achieved with climate data.

IIASA study proposes solid air hydrogen liquefaction as efficient addition to hydrogen liquefaction supply chain

Green Car Congress

The world is undergoing an energy transition to reduce CO 2 emissions and mitigate climate change. The possibility of selling hydrogen could result in a further expansion of solar and wind power in developing countries, contributing to their economies.

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. C, or 1.8 ?F,

Stanford study finds current carbon capture technology inefficient & increases air pollution

Green Car Congress

A study by Mark Z. Even if you have 100 percent capture from the capture equipment, it is still worse, from a social cost perspective, than replacing a coal or gas plant with a wind farm because carbon capture never reduces air pollution and always has a capture equipment cost. You can’t just ignore health costs or climate costs.
