The examination of the transportation of gases that can be used as fuel is important in terms of energy efficiency. In particular, determining how much energy is required to transport a specific gas through a pipeline at a specific pipe diameter and flow rate helps to fully utilise the energy of that gas. To address this need, the primary objective of this study is to develop the theoretical horizontal energy distance (THED) approach, which compares the energy expended during the transport of major gas fuels, which can also be used in the future, in pipelines with the calorific value of the fuel. This approach shows how much pipeline length corresponds to the chemical energy contained in the fuel at the selected pipe diameter and flow velocity. In this context, the THED values of 22 gaseous fuels existing at 1-5 bar pressure range at 25 °C ambient temperature were determined, compared and interpreted at different pressures, pipe diameters and flow velocities. Among all cases in the study, carbon monoxide gas at 1 bar pressure, 0.01 m pipe diameter, and 100 m/s velocity yielded the lowest THED values at 1.0157 km, while hydrogen gas was calculated to have the highest THED value at 736,490,717 km at a pressure of 5 bar, a diameter of 1 m, and a flow velocity of 0.01 m/s. In general, hydrogen was found to be the gas fuel with the highest THED value in most cases, while carbon monoxide was the gas fuel with the lowest THED value in all cases. Consequently, the proposed THED metric provides a critical benchmark for evaluating the transport efficiency of future energy carriers, highlighting Hydrogen's superior potential for long-distance pipeline networks compared to other gaseous fuels.
