In this episode of Earthlings 2.0, we chat with Rob Alexander, CEO of AlumaPower, about a new way to generate clean, on-demand electricity using recycled aluminum. AlumaPower’s galvanic aluminum-air generator releases the energy already contained within aluminum through a chemical reaction with air and water — producing zero-emission power at the point of use and a reusable byproduct. We discuss how the company overcame the chemistry hurdles that held back aluminum-air systems for decades, the path to commercialization, and why aluminum could emerge as a global, circular energy carrier.
Key Points:
- Recycled aluminum as fuel – The system extracts stored energy from low-purity scrap aluminum, avoiding landfill and turning waste metal into a clean power source.
- Backup power focus – Early deployments target data centers and other critical infrastructure where reliability, quiet operation, and reduced emissions replace diesel generators.
- Modular scalability – Each cell generates 150 watts, stacking into containerized systems for megawatt-scale power; commercial launch planned for 2026.
