Under the agreement, Siemens will test Aquion’s aqueous hybrid ion (AHI) batteries with its Sinamics S120 drive technology.

Siemens new technologies director Razvan Panati said that the company wants to explore the Aqueous AHI technology proposed by Aquion, validate its capabilities and potential for offering cost effective grid-scale deployments and energy efficient microgrid and renewables support functions.

"Our intention is to support the Aquion team in developing fully integrated AHI-based energy storage systems using our scalable, industry proven, off-the-shelf inverter technology," Panati added.

Currently, Siemens’ Sinamics S120 inverter solution and Aquion’s AE12 microgrid and grid batteries are undergoing tests at Aquion’s R&D facility in Pittsburgh.

Aquion CEO Scott Pearson said that the company’s work with Siemens is a key step in the validation of its technology at commercial scale as it significantly ramps its production capacity.

"We look forward to showing that AHI batteries can be integrated with Siemens inverters to deliver cutting-edge storage solutions that are reliable, safe, cost-effective and environmentally benign to customers on a global scale," Pearson added.
