The rise of metal fuels
Richard Wang, co-founder and CEO of Voya Energy, explains how his company is replacing diesel generators with electrochemical generators powered by aluminum pellets. Wang details why diesel remains dominant due to its high energy density and low cost, but highlights its issues with emissions, noise, and permitting, particularly for data centers. He describes Voya's metal-air cell technology, which offers superior power quality, compact footprint, and zero air emissions, while leveraging low-grade scrap aluminum as a cost-competitive fuel source.
