To provide an offshore energy storage device which enables effective utilization of renewable energy.SOLUTION: An offshore energy storage device comprises: a platform provided on a sea surface of an ocean in a floating state; and a plurality of energy storage devices provided in a distributed manner below the platform. Each of the plurality of energy storage devices generates buoyancy force in the ocean and causes the platform to float in a vertically stabilized state. Each of the plurality of energy storage devices includes: a first water tank; a second water tank; one or more communication passages connecting the first water tank with the second water tank; an electric water pump for pumping water from the second water tank to the first water tank through the communication passages; and a power generator that generates electric power from downward flow of water from the first water tank to the second water tank through the communication passages.SELECTED DRAWING: Figure 1

    【課題】再生可能エネルギーの有効利用を可能とする洋上エネルギー貯留装置を提供する。【解決手段】洋上エネルギー貯留装置は、浮遊状態で海洋の海面に設けられるプラットフォームと、このプラットフォームの下部に分布して設けられた複数のエネルギー貯留装置と、を備える。複数のエネルギー貯留装置それぞれは海洋中で浮力を発生させ、プラットフォームを上下方向に安定させた状態で浮遊させる。複数のエネルギー貯留装置それぞれは、第1水槽と、第2水槽と、第1水槽と第2水槽とを連通する単一又は複数の連通路と、第2水槽から第1水槽へ連通路を通って揚水する電動揚水機と、記第1水槽から第2水槽へ連通路を通って流れる落水によって発電する発電機とを有する。【選択図】図1
