MITEI study finds hydrogen-generated electricity is a cost-competitive candidate for backing up wind and solar

Green Car Congress

A team at MITEI (MIT Energy Initiative) has found that hydrogen-generated electricity can be a cost-competitive option for backing up wind and solar. California draws more than 20% of its electricity from solar and approximately 7% from wind, with more VRE coming online rapidly.

Coal is losing the price war to wind and solar faster than anticipated

Electrek

The costs of most existing coal-fired power plants in the US are now more expensive than the total costs of wind and solar as a result of their plunging costs, according to a new study. more… The post Coal is losing the price war to wind and solar faster than anticipated appeared first on Electrek.

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 degrees Celsius.

Study finds GWP of electrolyzed hydrogen to meet ORD’s fuel needs would be 2.5x that of fossil fuels with 2020 grid mix

Green Car Congress

As a part of the study, Ansell assumed the adoption of one of the NREL zero emissions electric grids—one that has heavy concentrations of solar, wind, and other renewable energy sources. These might be a combination of solar arrays or wind turbines.

Argonne study shows range of GHG reductions for electrofuel Fischer-Tropsch; up to 108% reduction

Green Car Congress

In a paper in the ACS journal Environmental Science & Technology , they report that using nuclear or solar/wind electricity, the stand-alone FT fuel production (Naphtha, jet, diesel) from various plant designs can reduce WTW GHG emissions by 90–108%, relative to petroleum fuels. Zang et al.
