Abstract
Lighter-than-air airships were once a promising mode of transportation but declined in use due to early material limitations, safety failures, and competition from heavier-than-air aircraft. Despite this historical setback, advancements in material science, photovoltaics, and hydrogen risk modeling warrant a renewed investigation into the feasibility of airships as a method of shipping. This study evaluates the technical and environmental viability of modern thermally-powered, hydrogen-lift airships designed for overland freight transport. Emphasis is placed on disaster relief applications and cargo delivery in regions lacking conventional infrastructure. Drawing on contemporary hydrogen safety assessments and current shipping rates, this research evaluates whether or not the systems in question can be not only viable, but also competitive as a method of transportation. Additionally, the near-zero operational carbon output is assessed in comparison to alternative methods of freight transport. The findings of the research argue that thermally-powered lighter-than-air hydrogen airships may be a viable alternative to modern freight systems.
