Tower of power: gravity-based storage evolves beyond pumped hydro

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.

Energy-based control of double pendulum cranes

In this paper, we present a new energy-based saturated control law for underactuated cranes with double pendulum payload dynamics. Specifically, we construct a new energy storage function to enhance the internal state coupling and then design a saturated output feedback controller. After that, rigorous theoretical analysis is provided to prove that the …

Energy coupled–dissipation control for 3-dimensional overhead cranes …

Handling loads with small swings is difficult for a 3-dimensional overhead crane due to its hard nonlinearity. Moreover, the nonlinear dynamics increases the complexity of the required feedback, thus making the closed-loop system sensitive to a variation in the cable length that negatively influences the damping feature. To address …
