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

Green Car Congress

To provide 50%—or more—of power from clean energy sources, power grids will have to be able to leverage distributed energy sources, and reliably manage dynamic changes, while minimizing impact on customer quality of service. We will be replicating the entire California power grid on one campus.

Baker Institute report: China has positioned itself as a gatekeeper to the energy transition; nickel case study

Green Car Congress

Widely ignored, although gaining attention, is China’s strategic positioning as a crucial gatekeeper to several key “green” technologies, including battery energy storage to support electric vehicles (EVs)—specifically, battery electric vehicles (BEVs)—along with stationary storage for power grids.

How is New Zealand disposing of EV batteries?

Drive Electric

However, as the number of EVs on our roads continues to grow, so too does the number of old EV batteries requiring responsible disposal. According to estimates from EECA, an EV battery is expected to last 10 to 20 years (and more than 350,000km!) So, what happens to EV batteries once they have done their dash?

CMU researchers find controlled charging of PHEVs can cut cost of integration into electricity system by 54-73%; higher benefits with wind power

Green Car Congress

The magnitude of these savings is ~5% to 15% higher in a system with 20% wind penetration compared to a system with no wind power, and the savings are 50–60% higher in a system that requires capacity expansion. —Weis et al.

NREL researchers evaluating blockchain for transactive energy applications

Green Car Congress

The Congressional Research Service last year noted increasing interest among producers of distributed energy resources (DERs)—such as rooftop solar—to sell electricity to neighbors. Electricity generated from renewable resources such as solar and wind that customers cannot use can be diverted to the grid, but there are limits.
