PNNL study finds 2028 grid resource adequacy likely sufficient for high EV penetration; managed charging strategies can double adequacy

Green Car Congress

A new study of the impact of high EV adoption on the Western US power grid by a team from Pacific Northwest National Laboratory (PNNL) has found that 2028 grid resource adequacy—from generation through transmission—is likely to be sufficient for high EV penetration. Source: PNNL.

U-M researchers challenge USPS EV environmental study

Green Car Congress

A new University of Michigan study finds that making the switch to all-electric mail-delivery vehicles would lead to far greater reductions in greenhouse gas emissions than previously estimated by the US Postal Service (USPS). The Postal Service has not commented on the U-M study. Earlier post.). The USPS estimate was 10.3

Ford, U Mich study finds greater greenhouse gas reductions for pickup truck electrification than for other light-duty vehicles

Green Car Congress

. … there is substantial variation in emissions based on where and when a vehicle is charged and operated, due to the impact of ambient temperature on fuel economy and the spatiotemporal variability in grid carbon intensity across the United States. This is an important study to inform and encourage climate action. —Woody et al.

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

Green Car Congress

The open-access paper on the study is published in the RSC journal Energy & Environmental Science. The solar-grid scenario assumed that the hydrogen site is connected to the regional grid—the North West Interconnected System (NWIS) of Western Australia. Process flow diagram and construction phase boundary. Palmer et al.

NREL study finds most depot charging could accomodate short-haul heavy-duty electric trucks without upgrades

Green Car Congress

In most cases the existing technology grid can accommodate truck charging at depots. That perception is shifting, and our research suggests that certain short-haul operations can be electrified today with relatively low-power depot charging that won’t overwhelm the grid. 100 kW/vehicle) for the fleets studied.

NREL study finds that uncoordinated plug-in vehicle charging could prove challenging to the grid

Green Car Congress

An influx of plug-in electric vehicles (PEVs) charging without coordination could prove challenging to the nation’s electric grid, according to research conducted by the US Department of Energy’s National Renewable Energy Laboratory (NREL). Muratori noted that might be true in the future, but not necessarily.

New long-duration, extended capacity Na-Al battery design for grid storage

Green Car Congress

The new battery design could help ease integration of renewable energy into the electrical grid at lower cost, using Earth-abundant metals, according to a study just published in Energy Storage Materials. The new sodium-based molten salt battery uses two distinct reactions. The team previously reported a neutral molten salt reaction.
