The economic feasibility of energy storage systems strongly depends on the political decisions that will be made in the near future. The strength and ideal compatibility of one or many combination possibilities play a decisive role in the evaluation of an economic analysis.
Alternative energy storage concepts, like the pumped storage capacities in Central Europe, often require increased transmission capacities which lead to a costly expansion of the transmission and distribution network. The decentralized use of floating hydraulic energy storage devices directly at the site of energy production or consumption could prevent a large proportion of said network expansion costs, while the transmission losses would be minimized. Coastal cities, offshore wind energy or photovoltaic parks are locations that would be ideal for preventing excess costs and minimizing transmission losses.
