NREL modeling power requirements for regional air mobility

Green Car Congress

The project includes evaluating how smaller airports could supply clean power to both the aircraft and the region. How that happens exactly—whether from on-site renewables or grid supplied—is a site-by-site discussion. Regional air mobility continues the conversation to include electrified (and maybe automated) aircraft.

Georgia Tech team develops high-performance intermediate-temperature sold-oxide fuel cell

Green Car Congress

A team from Georgia Tech, with colleagues at the university of Kansas, has designed a high-performance solid-oxide fuel cell that operates directly on nearly dry (only ~3.5 vol% H 2 O) methane at 500 °C, demonstrating a peak power density of 0.37 C (achieving a peak power density of 0.37?W?cm d , A top-down view of the ARL.

ARPA-E awards $35M to 12 new projects to support medium-voltage devices for grid, industry and transportation

Green Car Congress

The US Department of Energy announced $35 million in awards for 12 projects that find new ways to harness medium-voltage electricity for applications in industry, transportation, on the grid and beyond. BREAKERS projects will develop DC devices that prevent electric arcing, a safety hazard, while handling large amounts of power and voltage.

The EV Transition Explained: Can the Grid Cope?

Cars That Think

There have been vigorous debates pro and con in the United States and elsewhere over whether electric grids can support EVs at scale. Further, the system was designed for one-way power, not for distributed renewable-energy devices sending power back into the system. The answer is a nuanced “perhaps.”

ARPA-E awards $30M to 21 projects advance new class of high-performance power converters

Green Car Congress

CIRCUITS project teams will accelerate the development and deployment of a new class of efficient, lightweight, and reliable power converters, based on wide-bandgap (WBG) semiconductors. If successful, the team will construct a 500 kW building block for a DC fast charger that is at least four times the power density of todays installed units.

The Energy Transition Requires a Holistic Approach

Cars That Think

Deepak Divan We start at a place where science lagged technology and the market by a significant amount in the early years of the power industry. When the electricity grid was established, it was the Wild West, with every entrepreneur trying to get ahead of the others with their own proprietary solutions. Unless U.S.
