Prediction of vortex-induced vibration effects on a subsea gravity energy storage module

Subsea buoyancy gravity energy storage systems (SBGESS) could take advantage of large water depth to store energy in the form of potential energy. In the proposed system, drum hoists mounted on a semisubmerged support structure simultaneously lift concrete cylinders with hundreds of tonnes and lower floaters with equivalent buoyancy force,...

System model development and numerical simulation of low-head pumped hydro storage

To tackle the growing demand for grid-scale energy storage, the ALPHEUS project proposes a novel low-head pumped hydro storage system aimed for coastal application in countries where the topography does not allow for traditional high-head storage. This system consists of a reversible pump-turbine technology with two contra-rotating runners...

A control-oriented wind turbine dynamic simulation framework which resolves local atmospheric conditions

Wind turbines may experience local weather perturbation, which is not taken into account by the commonly-used wind turbine simulation packages. Without this information, it is extremely challenging to evaluate the controller performance with regard to the effect of the variation of local atmospheric conditions. On the other side, it is too...

Multi-criteria analysis to rank offshore renewable technologies to support deep-water oil and gas production

Around 5% of the global offshore oil and gas production is consumed as fuel to power the platforms emitting around 200 million tons of CO2 per year. Adopting renewable energy can increase the oil and gas available for export by reducing internal consumption and opening space for the processing plant. This work presents an improvement to the...

Simulation of a horizontal axis tidal turbine for direct driven reverse-osmosis desalination

Desalination of seawater from renewable energy sources is without doubt an appealing solution to face water scarcity issues in coastal areas. In particular, tidal energy technologies offer high potential to be integrated with existing desalination technologies. This paper contributes to the idea of using a horizontal axis tidal turbine for...
