As the world increasingly seeks to move away from fossil fuels amid the climate crisis, new innovative technologies have emerged to harness clean energy.
While renewable energy has been gaining momentum, it faces a challenge in providing energy reliably when demand is most required. For example, offshore wind farms not operating when it is not a windy day or when it continues to operate despite already meeting with the energy demand for the day poses a dilemma for the energy providers.
Thus, technologies or systems which can aid in clean energy storage are going to be key to addressing this issue.
Ocean Grazer, a Dutch-based startup company, presented its ‘ocean battery’ technology at the ongoing CES 2022 event on Thursday to highlight how it can address this dilemma faced by the renewable energy sector.
The ocean battery technology uses flexible and enormous bladders located on ocean floors, in which wind farms fill seawater. During the times when energy is required, the ocean’s pressure helps push water via the turbine, thus leading to electricity generation.
