Skip Technology raised $5 million to help the grid-scale battery startup begin deploying prototypes for field testing. The Portland, OR based company is building long-duration batteries that use hydrogen bromine rather than the more common lithium-ion chemistry. Skip Tech’s batteries hold power for a longer time, are less flammable, and require components that are easy to source domestically.

According to the CEO Brennan Ganter, the company’s smaller batteries will be able to power offline operations like food trucks, while a collection of about 10 shipping container-sized batteries could provide enough power for a large data center.

The new investment round is being led by Puyallup Tribal Enterprises, which also invested in a previous round. Skip Tech and the Washington-based tribal organization are additionally partnering in production of the batteries. Puyallup Tribal Enterprises is building a manufacturing facility south of Seattle to make the devices.
