Hydrogen is emerging as an energy carrier to better manage and store excess electricity generated through sustainable solar and wind systems. The development of hydrogen fuel cells for mobility applications is gaining traction, and with the various public and private sector initiatives to propel hydrogen mobility come immense growth opportunities for fuel cell trucks. Incentives are available for fleets, especially during the initial transition period, to offset high vehicle prices, infrastructure installation, and hydrogen costs.

One of the major challenges in promoting fuel cell trucks is onboard hydrogen storage, especially in high quantity for long-haul transport. Unlike diesel tanks, hydrogen tanks need to maintain a specific pressure for supply to the fuel cell stacks. Hydrogen is generally stored in the gaseous state at either 350 bar or 750 bar, and in liquid state at cryogenic temperature of -253°C. Manufacturers of hydrogen storage tanks traditionally supply products for stationary and aerospace use, but some companies are aggressively establishing themselves with options to suit different vehicle platforms.

Carbon composite is the prevalent material used for lightweight, high-strength hydrogen storage tanks. Companies with expertise in materials and the manufacture of carbon composites are exploring hydrogen mobility business opportunities.
