Metal Hydride Hydrogen Compressors for Industrial-Scale Green Hydrogen: A Techno-Economic Analysis and Market Readiness Assessment

The emerging hydrogen economy requires cost-effective compression solutions to enable industrial-scale adoption. The paper presents a comprehensive techno-economic analysis and market readiness assessment of metal hydride hydrogen compressors (MHHCs) for 60 tons per day (TPD) green hydrogen production facilities. Unlike conventional mechanical compressors, MHHCs offer non-mechanical, thermally-driven compression with potential operational advantages including reduced maintenance, elimination of lubricant contamination, and silent operation. Through systematic analysis of capital expenditure (CAPEX), operational expenditure (OPEX), total cost of ownership (TCO), and comparative evaluation against mechanical alternatives, this study quantifies the economic viability of MHHC technology. Market analysis reveals growing interest among hydrogen producers, with 73% of surveyed stakeholders acknowledging technical advantages but expressing concerns about initial costs and material availability. The analysis demonstrates that while MHHC systems require 47-52% higher initial investment compared to mechanical compressors, they offer 23-31% lower operational costs over a 10-year lifecycle. Technology readiness level (TRL) assessment indicates MHHCs are at TRL 6-7, requiring targeted policy support and demonstration projects to accelerate commercialization. This research provides decision-making frameworks for investors, policymakers, and hydrogen project developers evaluating compression technology choices in emerging markets.
