Dutch energy supplier Budget Thuis has agreed to install a long-duration energy storage system developed by Ore Energy, marking a significant step in the deployment of iron-air battery technology for the national grid.

The installation is designed to store green electricity for extended periods, addressing the intermittency challenges inherent in renewable energy generation.

The partnership highlights a growing interest in alternative storage chemistries beyond traditional lithium-ion batteries.

Iron-air technology, often referred to as a "rust battery," offers lower material costs and longer discharge times, making it suitable for storing excess renewable energy generated during peak production hours for use during periods of low generation.

This development aligns with broader European efforts to diversify energy storage portfolios and reduce reliance on critical raw materials.

Budget Thuis, a major player in the Dutch residential energy market, aims to enhance grid stability and support the transition to a fully renewable energy mix.
