Technical and Economic Aspects of Electric Energy Storage in a Mine Shaft—Budryk Case Study

The transformation of the energy sector towards an increased share of renewable energy sources in the energy mix requires attention in the area of electricity storage. Renewable energy sources (photovoltaics or wind energy) are marked by the intermittency of electricity production and require the co...
