Abstract: Hydrogen's immense potential as a future fuel is undeniable, but its low volumetric energy density poses a critical challenge to the development of a hydrogen economy. Hydrogen compression offers a promising solution, with methods broadly classified into mechanical and non-mechanical compressors. While mechanical compressors are widely used in stationary and automotive applications, they suffer from high energy consumption, noise, vibration, and frequent maintenance needs. This has driven global efforts to develop non-mechanical hydrogen compressors as promising alternatives. This review provides a comprehensive overview of state-of-the-art non-mechanical compressors, including metal hydride, electrochemical, adsorption, and cryogenic systems. Each technology is examined in terms of operating principles, design challenges, and potential solutions, covering prototypes to large-scale systems developed worldwide. Key findings from experimental demonstrations are summarized, and the performance of these compressors is compared based on efficiency, compression rates, and economic viability. The assessment finishes by noting important research gaps and technological hurdles for the advancement of non-mechanical hydrogen compression technologies. It also emphasizes how well-suited these technologies are for hydrogen refuelling stations. • Role of hydrogen compression in the hydrogen economy. • Overview of key challenges faced by mechanical hydrogen compressor. • Comprehensive review of different types of non-mechanical hydrogen compressor. • Emphasis on significant research gaps being investigated. • Critical comparison and future perspective for holistic development.
