Going underground – why Gravitricity energy storage makes sense
But whether we build future systems in existing or purpose-built shafts, the only way to build cost-effective long-term gravity energy storage is to go underground. The principles which have led us to our design are laws of physics, applicable equally in all parts of the world, in all seasons, and in all conditions.
Life-cycle assessment of gravity energy storage systems for large-scale application …
Depending on the considered scenarios and assumptions, the levelized cost of storage of GES varies between 7.5 €ct/kWh and 15 €ct/kWh, while it is between 3.8 €ct/kWh and 7.3 €ct/kWh for gravity energy storage with wire hoisting system (GESH). The LCOS of GES and GESH were then compared to other energy storage systems.
