Abstract: In this work, we present a complete cross sections set that describe the interaction between H₂⁺ ions and H₂ molecules. Based on these cross sections, we have calculated the transport properties of H₂⁺ ions in H₂ gas, depending on the reduced electric field. Ionic charge exchange reactions with molecules are indispensable elementary processes in the modeling of kinetics in terrestrial, industrial and astrophysical plasma in the detection of dark matter. A Monte Carlo simulation method is applied to accurately calculate transport parameters in hydrodynamic regime. We discuss new data for H₂⁺ ions in H₂ gas where the mean energy the flux and bulk values of reduced mobility and other transport coefficients, are given as a function of low and moderate reduced electric fields.
