Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

They used the model and the data to estimate the life cycle air pollution, greenhouse gas, and traffic externality benefits and costs of serving rides based on Chicago TNC trip data from 2019 to 2022 with fully electric vehicles. A paper on their work is published in the ACS journal Environmental Science & Technology. —Mohan et al.

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. Vehicle-to-building works much the same way but on a larger scale.

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.
