DOE releases analysis of potential impacts of hyperloop technology on the grid

Green Car Congress

Hyperloop technology, initially proposed by Elon Musk in 2013 as an innovative means for intermediate-range or intercity travel, is now being developed by several companies. Because the system is powered by electricity, there is also potential for integrating a hyperloop system’s energy storage technologies with variable energy resources.

EDF-commissioned GNA study finds current and emerging electric heavy-duty trucks and charging systems capable of meeting most fleet needs

Green Car Congress

GNA modeled the impact of electrification on those fleets under a series of scenarios including managed charging and deployment of on-site solar and storage. However, despite those long-term savings, charging infrastructure investments required for Class 8 fleets are significant and can vary dramatically.

NREL study finds most depot charging could accomodate short-haul heavy-duty electric trucks without upgrades

Green Car Congress

In most cases the existing technology grid can accommodate truck charging at depots. That perception is shifting, and our research suggests that certain short-haul operations can be electrified today with relatively low-power depot charging that won’t overwhelm the grid. 100 kW/vehicle) for the fleets studied.

SwRI develops first ERCOT-qualified vehicle-to-grid aggregation system

Green Car Congress

SwRI’s V2G aggregation system allows electric delivery truck fleet owners to make money by using normal vehicle charge times to assist in managing grid frequency. The SwRI system suspends vehicle charging when the electric grid frequency drops too far below 60 Hertz, the normal operating frequency. Click to enlarge.
