We present Atacama Large Millimeter/submillimeter Array (ALMA) observations of the quadruply lensed z = 1.51 quasar HS 0810+2554 which provide useful insight on the kinematics and morphology of the CO molecular gas and the ∼ 2 mm-continuum emission in the quasar host galaxy. Lens modelling of the mm-continuum and the spectrally integrated CO(J = 3-2) images indicates that the source of the mm-continuum has an eccentricity of e ∼ 0.9 with a size of ∼1.6 kpc and the source of line emission has an eccentricity of e ∼ 0.7 with a size of ∼1 kpc. The spatially integrated emission of the CO(J = 2-1) and CO(J = 3-2) lines shows a triple peak structure with the outer peaks separated by Δv₂₁ = 220 ± 19 km s^–1 and Δv₃₂ = 245 ± 28 km s^–1, respectively, suggesting the presence of rotating molecular CO line emitting gas. Lensing inversion of the high spatial resolution images confirms the presence of rotation of the line emitting gas. Assuming a conversion factor of α_CO = 0.8 M_☉ (K km s^–1 pc²)^–1 we find the molecular gas mass of HS 0810+2554 to be M_Mol = (5.2 ± 1.5)/µ₃₂ x 10¹⁰ M_☉, where µ₃₂ is the magnification of the CO(J = 3-2) emission. We report the possible detection, at the 3.0-4.7σ confidence level, of shifted CO(J = 3-2) emission lines of high-velocity clumps of CO emission with velocities up to 1702 km s^–1. We find that the momentum boost of the large-scale molecular wind is below the value predicted for an energy-conserving outflow given the momentum flux observed in the small-scale ultrafast outflow.
