OFFSHORE WIND TURBINE ARRANGEMENT AND METHOD FOR COOLING A HYDROGEN PRODUCTION APPARATUS OF AN OFFSHORE WIND TURBINE ARRANGEMENT

An offshore wind turbine arrangement (1), comprising
a wind turbine (2) for generating electrical energy by wind power,
a hydrogen production apparatus (12) for producing hydrogen gas (13) by means of the generated electrical energy, and
a cooling system (20) for cooling the hydrogen production apparatus (12),
wherein the cooling system (20) includes a subsea heat exchanger (21) for cooling a cooling liquid (22), and a pipe arrangement (23) forming a closed loop (25) for guiding the cooling liquid (22) from the subsea heat exchanger (21) to the hydrogen production apparatus (12) and back.

Having a closed loop cooling cycling and a subsea heat exchanger, an energy efficiency of the cooling system can be increased.
