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

Green Car Congress

Today’s power distribution networks are primarily powered by alternating current (AC) electricity, but DC can provide lower distribution losses and higher power carrying capacity. Georgia Tech Research Corporation, EDISON – Efficient DC Interrupter with Surge Protection – $3,000,000. Georgia Tech is proposing a novel hybrid direct-current (DC) circuit breaker technology that will enable multi- terminal DC power systems.

ARPA-E awards $130M to 66 “OPEN 2012” transformational energy technology projects

Green Car Congress

ARPA-E’s previously selected projects have already made major progress, by demonstrating a 400 Wh/kg lithium-ion battery; building a wind turbine, inspired by the design of jet engines, that could deliver 300% more power than existing turbines of the same size and cost; and engineering a high power laser drilling system that can penetrate hard rock formations over long distances and is ten times more economical than conventional drilling technologies. Today’s separation methods are energy.
