By combining the concepts of pycnonuclear reactions at low temperatures and their enhancement due to strong internuclear Coulomb correlations, we predict the possibilities of a novel scheme for fusion in ultrahigh-pressure liquid-metallic hydrogen near the freezing conditions, for the reactions ^2H(p, γ)^3He, ^3H(d, n)^4He, and ^7Li(p, α)^4He. Time evolution is followed for p-d reaction after a pulsed compression with 1 kJ input and the initial conditions of mass density ≈ 20 g/cm^3, temperature ≈ 1400 K, pressure ≈ 490 Mbar, and radius ≈ 0.017 cm; an energy yield of 33 kJ in 0.03 fs is thus predicted.
