Technical design of gravity storage. The energy production of gravity storage is defined as: (1) E = m r g z μ. where E is the storage energy production in (J), m r is the mass of the piston relative to the water, g is the gravitational acceleration (m/s 2 ), z is the water height (m), and μ is the storage efficiency.
Based upon these models, pumped hydro has a LCOS of $0.17/kWh; our Energy Vault solution is below $0.05/kWh.". Equally, Energy Vault''s system is around 50% cheaper than battery storage technology, in particular lithium-ion batteries, which can have an LCOS of around $0.25/kWh-$0.35/kWh.
