Wind-to-Hydrogen Tech Goes to Sea

Cars That Think

Wind and solar parks produce a large portion of their energy. Then, as now, wind farms are operating off the world’s coasts—but not all of these offshore sites are connected to the mainland via underwater power cables. Some of the wind farms instead sit in clusters more than 100 kilometers out at sea.

Highview Power and Encore Renewable Energy to co-develop the first long-duration, liquid-air energy storage system in US

Green Car Congress

When electricity is in high demand and more valuable, the pressurized gas is allowed to warm, turning a turbine as it expands and thus generating energy that can be used at peak times when the sun is not shining and the wind is not blowing.

Proposed California Bill SB-233 Mandates Bidirectional Charging for EVs to Advance Grid and Climate Protection

Driivz

The bill, SB-233 , aims to advance grid resilience and protect the climate by using EVs as “batteries on wheels,” tapping their stored energy to balance electricity supply and demand rather than bringing high-polluting peak generators online. SB-233 covers school buses as well so they can power V2B and fleet depots use cases.

A123 Systems to supply 1MW Li-ion grid storage system to Maui Electric Company; 2MW system for NSTAR demonstration

Green Car Congress

Li-ion battery maker A123 Systems will supply a Grid Battery System (GBS) to Maui Electric Company (MECO), a utility serving residents and businesses on the islands of Maui, Lanai and Molokai in Hawaii. The system, NSTAR’s first battery energy storage project, is proposed for installation at a substation in Medway, Mass.

New lithium polysulfide flow battery for large-scale energy storage

Green Car Congress

The work is some of the earliest supported by the DOE’s new Joint Center for Energy Storage Research battery hub (JCESR). For solar and wind power to be used in a significant way, we need a battery made of economical materials that are easy to scale and still efficient. Batteries Power Generation Smart Grid'

CMU study finds controlled EV charging can reduce generation cost, but at greater health and environmental costs depending upon the generation mix

Green Car Congress

Results from the study also suggest that with sufficient coal plant retirement and sufficient wind power, controlled charging could result in positive net benefits instead of negative. Reduction in annual generation cost and external emissions costs due to controlled charging compared to uncontrolled charging ($2010).
