Simulative comparison between ship and airship for the transport of waste natural gas from oil wells

This paper proposes an innovative system for transporting natural gas from a site of extraction to a site of consumption, through the employ of drone airships. The airships contain slightly compressed methane within the hull volume and employ hydrogen as lift gas. In the paper the authors carry out a comparison between the proposed solution and a solution involving the employ of CNG ships. The comparison produced interesting results, from which emerged that the airship solution is advantageous in terms of transport costs, due to the absence of the gas compression phase.
