Three major challenges facing hydrogen as an energy carrier in terms of storage and logistics?

• A. High compression or liquefaction energy demands; leakage and embrittlement risks; developing dedicated infrastructure and high costs.
• B. Lack of demand and no regulatory hurdles.
• C. Insufficient energy density compared to batteries.
• D. Easy transport with existing natural gas pipelines.

Answer: (A)

Storage and logistics of hydrogen as an energy carrier are hindered by the energy needed to compress or liquefy it to usable storage densities, by leakage risks and material embrittlement that affect pipes and tanks, and by the requirement to build dedicated infrastructure—tanks, compressors, pipelines, and fueling networks—at high cost. This combination captures the main barriers: the substantial energy input to reach practical storage forms, safety and materials challenges from hydrogen’s properties, and the capital and logistical setup required to move and deliver hydrogen at scale. The other options gloss over real constraints: demand and regulatory hurdles do exist, energy density comparisons to batteries don’t fully reflect storage and transport challenges, and existing natural gas pipelines aren’t readily usable for pure hydrogen without significant upgrades.
