Independent Peer-Reviewed Study Validates iQ LOOP's Aluminium Energy Storage Thesis

2026

A new peer-reviewed paper published in Advanced Energy Materials — authored by researchers at the University of Perugia, AIT Austria, and the Karlsruhe Institute of Technology's Helmholtz Institute Ulm — provides independent scientific validation of the core mechanism behind iQ LOOP's platform: using aluminium as a circular carrier to store off-peak renewable electricity and release heat and hydrogen on demand.

The paper highlights aluminium's exceptional volumetric energy density — 23.5 kWh per litre, roughly sixteen times that of compressed hydrogen and an order of magnitude above liquid hydrogen — and finds that Europe's projected 1,300 TWh of seasonal storage need could be met with a fraction of the physical volume required by hydrogen alone. For iQ LOOP, the study offers a citable, third-party foundation for conversations with government, investors, and infrastructure partners.
