From trains that crisscross the country to the chargers that power your electric car, cables play an essential role in moving electricity—and you—from point A to point B. In fact, materials that conduct electricity are fundamental to nearly all energy applications, including smartphones, heat pumps, and power tools.

To connect all these devices alongside new, renewable power sources, the International Energy Agency estimates that we will need 10 million miles of new transmission cable, enough to travel to the moon and back 21 times. By improving conductors, we have the potential to make electricity more affordable, make the grid more resilient, and pave the way for the increasingly electrified industries of tomorrow.

To supercharge the effort, the U.S. Department of Energy’s (DOE’s) Advanced Manufacturing Office launched the Conductivity-enhanced materials for Affordable, Breakthrough Leapfrog Electric and thermal applications (CABLE) Conductor Manufacturing Prize.

The $4.5-million, three-stage prize, administered by the National Renewable Energy Laboratory (NREL), will help boost leading U.S. industries by developing new conductors with significantly enhanced conductivity, manufacturability, and affordability.

Cutting-Edge Conductor Materials

In Stage 1 of the prize, competitors will submit their concepts to develop and manufacture conductors—with an electric conductivity enhancement an unprecedented 7–8 times larger than that of today’s best copper- and aluminum-based conductors.

“These cutting-edge materials could be the answer to vastly improving the efficiency of motors, which account for 85% of electricity consumption in the U.S. manufacturing sector,” said Matt Ringer, NREL’s Advanced Manufacturing Office Laboratory Program Manager.

Stage 1 of the prize is geared toward attracting and introducing conductivity manufacturing communities to each other and identifying unfamiliar aspects of the challenge. An informational webinar is being held on March 30 to provide participants with additional information about the prize, and all Stage 1 competitors are invited to the April CABLE Big Idea Workshop.

With an end goal of garnering innovative concepts from a wide range of competitors, including those not traditionally involved in conductors, Stage 1 accepts submissions that either substantially improve upon existing combinations of materials and processes or are an entirely new type of conductor material enhancement.

Stage 1 concludes in June 2021, with as many as 10 winners each awarded $25,000 in cash prizes.

Scaling Up for Success

In Stage 2, competitors evaluate lab-scale samples of their material for conductivity. Stage 2 remains open to all innovators, with competitors invited to move their ideas from concept to actually fabricating conductor samples. DOE anticipates awarding up to $250,000 to as many as six winning teams.

The conductivity champs from Stage 2 advance to the third and final stage of the prize. In Stage 3, competitors fabricate manufacturing-scale samples for American-Made Network testing of conductivity and other characteristics. Teams will also be evaluated on their documented manufacturing process, scale-up plans, and cost. DOE anticipates that up to four winners will split a prize pool of at least $2 million.

In addition to the cash prizes, competitors in Stage 3 will be eligible for vouchers that will enable them to obtain services, resources, and CABLE Conductor assessments from DOE national laboratories and other American-Made Challenges Network providers.

“Concepts emerging from this prize have the potential to fundamentally change the grid, electric vehicles (including cars, trains, and planes), cables, motors, generators, and renewable power technologies,” said Ringer.
