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

Green Car Congress

Lead author Aniruddh Mohan and colleagues wanted to develop a method that evaluated the life-cycle costs and benefits for two battery-powered ridesource fleets and a gasoline-powered one. The analysis indicated that electrified fleets had 40-45% lower greenhouse gas costs per trip compared to the gasoline-powered version.

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.

PNNL study outlines requirements for grid storage, reviews four electrochemical energy storage systems: vanadium redox flow, Na-beta, Li-ion and lead-carbon

Green Car Congress

The future grid will face significant challenges by providing clean power from intermittent resources to a much more dynamic load. EES has been considered as a key enabler of the smart grid or future grid, which is expected to integrate a significant amount of renewable energy resources while providing fuel (i.e.,

A critical issue in decarbonization will also be the role of the electrical grid itself. Wind and solar farms are alternatives to fossil fuel-fired power plants. With current technology, these new forms of power plants require a great deal of land along with adequate transmission lines. We need off-grid and on-grid solutions.

Fraunhofer IAF develops first monolithically integrated GaN half bridge for voltage converters for e-mobility

Green Car Congress

In power electronics components, this is the standard volt class for grid-connected electrical devices, ranging from tablets and washing machines to e-bikes and electric cars. Monolithic integration combines several components on a single GaN chip, enabling extremely small, powerful systems to be created.

ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

The WTW analysis focused solely on the fuel-motive power cycle, disregarding the vehicle cycle—i.e., the associated energy and emissions for the battery, power electronics, and auxiliary systems found only on battery EVs and for the CNG tank and auxiliary systems only found on natural gas vehicles.
