GridScale – A Cost-effective Large-scale Power to Power Storage
The purpose of the project is to optimise a full-scale design of the GridScale storage technology achieving cost-effective large-scale power to power storage, covering both the 8-18 h duration required for day-to-day smoothing of solar PV, and the 3 to 7 days duration required for smoothing of wind power over gaps caused by low wind periods.
The aim is to optimise a full-scale design of the GridScale storage technology for the Danish and European energy system. Based on the GridScale technology, two energy system analyses will be carried out: one focusing on Lolland and one focusing on Europe.
Based on these, the optimal requirement specification for a full-scale plant will be developed for various applications, including energy islands.
A charge/discharge decision model will be developed. Turbomachinery tailored for charging and discharging the system will be optimized with consideration to both performance and cost by use of advanced models. Detailed numerical models for the storage units will be developed to optimize their design. The aim is to obtain a significant specific cost reduction for the whole system. Devel-opment work will, when possible, be validated on a pilot plant under construction in parallel with the EUDP project. The output of the project will be one or more optimized full-scale designs, ready for construction on the energy islands and in many other locations where energy storage is required.
