The company formerly known as Fluidic has two things that no other alternative battery startup has achieved: thousands of systems deployed and financial security.

The company chugged along, quietly churning out zinc-air batteries for remote deployments overseas, while those making flow batteries, saltwater batteries and miniaturized compressed air batteries ran out of money.

Over the last six years, it has installed 3,000 zinc-air battery systems in nine different countries, where they performed a cumulative 1.2 million cycles, Krishnan said.

Totaling 200,000 people, get 100 percent renewable-based electricity with microgrids backed by NantEnergy batteries, he added.

Duke Energy chose NantEnergy for its remote microgrid to power an outpost in the Great Smoky Mountains National Park, and NantEnergy has also delivered a telecom application in California, Krishnan said.

Flow batteries hold the potential for cheap, long lasting storage, but they haven’t reached large-scale commercial deployment.

Now in its fourth year, GTM’s Energy Storage Summit will bring together utilities, financiers, regulators, technology innovators and storage practitioners for two full days of data-intensive presentations, analyst-led panel sessions with industry leaders, and extensive, high-level networking.
