EPFL team develops low-cost catalyst for splitting CO2

Green Car Congress

EPFL scientists have developed an Earth-abundant and low-cost catalytic system for splitting CO 2 into CO and oxygen—an important step towards achieving the conversion of renewable energy into hydrocarbon fuels. Using only Earth-abundant materials to catalyze both reactions, this design keeps the cost of the system low.

Discharge mode is shown; the arrows are reversed for electrolytic/charge mode. Wide-scale utilization of flow batteries is, however, limited by the abundance and cost of these materials, particularly those using redox-active metals and precious-metal electrocatalysts.

Xcel Energy wants 1.5M EVs in its service areas by 2030; 30x increase from today

Green Car Congress

Electric vehicles are the next frontier in the clean energy transition, and we are committed to making charging EVs easy, convenient and affordable for customers. Electric vehicles charged on the increasingly clean Xcel Energy system will have about 80% lower carbon emissions than gas-powered cars by 2030.

Convert Oil Wells to Solve the Solar Storage Problem

Cars That Think

The idea, says Daniel Codd , a researcher in renewable energy systems at the University of California, San Diego, is to store solar-produced heat in rock formations below the surface, creating a solar-charged geothermal resource in which heat is stored for meaningful durations. But we can still reduce the carbon [cost] of that oil.”

FedEx adds 1,900 new lightweight composite Reach vans to fleet; 35% fuel efficiency improvement

Green Car Congress

FedEx is also working with XL Hybrids, a developer of low-cost hybrid electric powertrain system, to convert ten conventionally-powered panel vans into more fuel-efficient, hybrid vehicles. Argonne will collect the electric energy consumption of the vehicles to help determine the total cost of operating an electric vehicle fleet.

TeraWatt Infrastructure aims to address the massive energy capacity needs of EV fleet charging depots

Charged EVs

As more fleets of medium- and heavy-duty vehicles go electric, there’s a growing awareness that building the necessary charging infrastructure will be a complex proposition, requiring specialized expertise and considerable capital. TeraWatt has only recently come out of stealth mode, and has yet to announce any major customers.
