Techno-economic Assessment of Storage Technologies
The techno-economic assessment of hydrogen storage technologies reveals significant cost variations across different methods. Conventional compressed hydrogen storage systems currently offer the lowest capital expenditure at approximately $500-800/kg H₂, but their operational costs increase due to energy-intensive compression processes requiring 10-15% of the hydrogen's energy content. Liquid hydrogen storage presents higher initial investment costs ($1,200-1,800/kg H₂) with substantial operational expenses due to liquefaction consuming 30-40% of hydrogen's energy value.
Metal hydride storage systems demonstrate promising economics for specific applications, with capital costs ranging from $1,500-3,000/kg H₂. While these systems have higher upfront costs, they offer reduced operational expenses through lower pressure requirements and potential heat integration opportunities. For catalyst and anode optimization applications, the total cost of ownership analysis indicates that metal hydrides may provide better long-term value despite higher initial investments.
Advanced materials such as complex hydrides and metal-organic frameworks (MOFs) currently show higher costs ($3,000-5,000/kg H₂) due to limited commercial scale production, but projections suggest potential cost reductions of 40-60% within the next decade as manufacturing processes mature. The levelized cost of hydrogen storage (LCHS) analysis indicates that material-based storage systems could achieve cost parity with compressed hydrogen by 2030 if current R&D trajectories continue.
Energy efficiency considerations significantly impact the economic assessment, with material-based storage systems potentially offering 15-25% higher round-trip efficiency compared to conventional methods when optimized for catalyst and anode applications. This efficiency advantage translates to approximately $0.50-0.80/kg H₂ in operational savings over the system lifetime.
Infrastructure requirements present another critical economic factor. Compressed and liquid hydrogen storage necessitate substantial investments in specialized equipment, while material-based systems may leverage existing infrastructure with modifications. The capital expenditure for infrastructure adaptation ranges from $50-200/kg H₂ annual capacity, depending on the specific storage technology and scale of implementation.
Market analysis indicates that early adoption of advanced storage materials for catalyst and anode applications will likely occur in high-value sectors where performance advantages outweigh cost premiums, such as electronics manufacturing and specialized industrial processes, before expanding to broader energy storage applications as economies of scale develop.
