Problem
The intermittent nature of renewable energy sources like solar and wind creates challenges in ensuring a consistent and reliable energy supply. Existing energy storage solutions often lack the capacity for long-duration storage and cost-effective transportation of renewable electricity, hindering widespread adoption.
Solution
Altiro Energy is developing an iron-based energy storage system designed for long-duration storage and transport of renewable energy. The technology utilizes a reversible process where iron powder is cycled through charging and discharging phases. During charging, iron and oxygen are separated, storing energy. When energy is needed, the iron and oxygen recombine, releasing heat that can be used for power generation. The resulting iron oxide (rust) can then be recharged, creating a closed-loop, zero-emission system. This approach enables renewable energy producers to store excess energy and distribute it to consumers on demand, regardless of duration or distance.
Target Audience
The primary target audience includes large renewable energy producers seeking solutions for energy storage and distribution, as well as consumers with limited access to consistent renewable energy sources.
