A hydro-pneumatic wave and heave power station for converting wave and heave energy, whereby for utilizing the hydrostatic pressure difference of the amplitudes of wave tops and wave valleys with a continually shifting phase, two or more mutually co-operating but mechanically not coupled pistons (2, 19) with a relatively large diameter are used, which, during downward movement, use the pressure difference for directly driving hydraulic cylinders (10, 21), which by means of a hydraulic rectifying circuit (14) transfer their kinetic energy to a hydraulic motor (18) coupled with an electrical generator, which pistons are returned again towards their highest position by means of a gas (4) compressed during the downward stroke, which gas, after expansion, is still in equilibrium with the water column above the piston, the generated electrical current being transferred by means of cables towards a utilization or distribution point on the mainland.
