AB - The diffusion coefficients of CO2 and H2 in aqueous solutions are important in numerous processes including carbon capture, geological carbon storage, and reservoir storage of hydrogen. As CO2 is reactive in some aqueous solutions, especially aqueous amine solvents for carbon capture, N2O is frequently studied as a surrogate. In this work, the Taylor dispersion technique was used to determine the diffusion coefficients of N2O and H2 at high dilution in water at temperatures between 298.15 and 423.15 K and at pressures up to 30 MPa, with a standard relative uncertainty of 1.6%. The new data are intended to resolve significant discrepancies in the literature. The results confirm that temperature is the most important controlling factor and that the diffusion coefficients are nearly independent of pressure in the region studied. The experimental data were correlated using the Stokes–Einstein equation, with average absolute relative deviations of 0.5% for both systems.
