Innovative hydrogen compression

CSIRO, in collaboration with Griffith University, are developing metal-hydride (MH) based H2 compression technologies.

MH-based H2 compression utilises a reversible heat-driven interaction of a hydride-forming metal alloy or intermetallic compound with hydrogen gas. Metal hydride-based compressors have various advantages including safety, absence of moving parts, compactness, low operational and maintenance costs, and the ability to use waste heat instead of electricity to achieve compression.

The project aims to design, build, and demonstrate a MH compressor able to compress H2 from 10 to 350 bar.
