Energy storage connector rusted

Could iron rusting help Xcel Energy's transition to cleaner energy?

Xcel Energy is planning to install a 10-megawatt battery system in Becker, Minn. where it’s building a large solar project. In central Minnesota, a first-of-its kind pilot project will test whether new battery storage technology that uses a common process — iron rusting — could play a key role in the nation's transition to cleaner energy.

How does a battery rust?

It uses an electro-chemical process called oxidation, or rusting. The battery takes in oxygen from the air and converts the iron to rust. Applying an electrical current converts the rust back to iron. Repeating the rusting and unrusting process allows the cell to charge and release electricity.

What is a reversible rust battery?

It works as a “reversible rust battery,” which means that while discharging, the battery breathes in oxygen from the air and converts metallic iron to rust. While charging, with the application of an electrical current, the battery converts “rust” back into metallic iron and breathes out oxygen. Here’s a deeper look at the battery cycle.

How do air electrodes convert rust to iron?

This turns the coating of the metal into rust (iron oxide). Then to recharge, the air electrode consumes hydroxide ions to form fizzy oxygen bubbles on charge, when the direction is reversed. Then the rust is converted back to iron metal.

Why do we need a special connection technology for storage systems?

They therefore make a significant contribution to alleviating the load on power grids and support the integration of renewable energy into the power grid. Special connection technology optimized for use in storage systems is required in order to connect these storage systems quickly, safely, and efficiently.

How do I connect my energy storage system?

Install your energy storage systems quickly, safely, and cost-effectively for applications up to 1,500 V – with pluggable battery connections via busbar connection or via battery pole connector. Benefit from the advantages of both connection technologies for front or rear connection.
