It is shown that the LCOS decreases up to 28.8% when decreasing the discount rate from 8% to 6%. Whereas a discount rate of 4% results in a decrease of up to 47.5% reduction in the LCOS of the investigated systems. For example, The LCOS for Gravity Storage would fall from 111 US$/MWh to 87 and 66 US$/MWh.

Underwater gravity energy storage has received small attention, with no commercial-scale BEST systems developed to date [28].The work thus far is mostly theoretical and with small lab-scale experiments [29].. Alami et al. [30], [31], [32] tested an array of conical-shaped buoys that were allowed to rotate. ...
Mechanical energy storage systems, such as pumped hydro storage [28], and electrochemical energy storage technologies [29] hold great significance in the progression of renewable energy. Currently, pumped hydro energy storage (PHES) dominates ES technologies, with ∼95 % of the global storage capacity [ 30 ].
plants include tower gravity energy storage [26-28], well-type gravity ener gy storage [29-32], mine car gravity energy storage [ 33-35], with cable car gravity ener gy storage [36].
Low-carbon energy transitions taking place worldwide are primarily driven by the integration of renewable energy sources such as wind and solar power. These variable renewable energy (VRE) sources require energy storage options to match energy demand reliably at different time scales. This article suggests using a gravitational-based …
