How should a large floating flywheel be operated to store offshore renewable energy profitably?
The authors show that, when accounting for hydrodynamic drag, wind forcing and fluctuating electricity prices, optimal operation typically reduces to a simple rule: maintain an almost constant rotational speed and switch between charging and discharging at a critical electricity price.
A fascinating example of how mathematical modelling can help optimise renewable energy storage and support the transition to more sustainable energy systems.

Large-scale energy storage is increasingly required to support offshore renewable generation, motivating interest in floating mechanical storage systems. Here we study the large-scale storage of kinetic energy via a floating offshore flywheel. We develop a simple mathematical model for the flywheel....
