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

Green Car Congress

Researchers led by the Department of Energy’s Pacific Northwest National Laboratory (PNNL) have extended the capacity and duration of sodium-aluminum batteries. The new sodium-based molten salt battery uses two distinct reactions. The team previously reported a neutral molten salt reaction. of peak charge capacity. —Weller et al.

NSF awards UCSD team $39M to improve integration of distributed energy resources into grid; EV batteries also

Green Car Congress

The major driver for the project is the need to decarbonize the electrical grid, protect it from cybersecurity attacks and make it more resilient. We will be replicating the entire California power grid on one campus. The goal is to make the testbed available to outside research teams and industry by 2025.

CoBank report finds that troubled US grid may need to use EVs for grid balancing

Green Car Congress

Since its inception, the US electric grid has mostly operated smoothly as one synchronous machine with a one-directional flow of electricity to meet the nation’s predictable power needs. The US electric grid is experiencing something of a mid-life crisis. US power outages are up 64% this decade compared to the previous decade.
