High-rise buildings could soon use gravity energy storage, say researchers

Researchers in Canada have proposed using gravity-based energy storage in high-rise buildings, in combination with photovoltaic facades, small wind turbines, and lithium-ion batteries. Their modeling indicated that this hybrid system could achieve a levelized cost of energy ranging from $0.051/kWh to $0.111/kWh.Researchers at the University of Waterloo in Canada have designed a solid gravity energy storage system that could be used to store renewable energy in high-rise urban buildings. The rope-hoist-based system is designed to operate in combination with photovoltaic facades installed on the ...
