Abstract

The world is phasing out fossil fuels and implementing policies that quickly increase their share of renewable energy, especially in electricity production. However, intermittent renewable energy sources have limited capacity for regulation of energy balancing due to lacking technologies for energy storage and efficient way of energy exploitation. The presentation includes a new way of computational investigation for sensible heat storage in sandstone and energy capacity estimation for a fluid bearing geothermal reservoir using the Finite Element Energy Simulator.

The specific attention on

• Future energy solution test set-up for wind energy storage

• In-situ laboratory at Groß Sch¨onebeck geothermal reservoir

Future energy solution promises an extremely low-cost set-up and will set a standard in efficiency for energy storage technologies. The test set-up reviews how to make charging the storage particularly efficient with respect to arrangements of sandstone in rock fills. Present investigation showed that sandstone size and airflow play a crucial role in heat storage. Modeling for well-doublet water circulation at the Groß Sch¨onebeck geothermal reservoir, prior to the experiment, suggests the thermal breakthrough has occurred after 18 years of power production and the life time of the reservoir is 50 years. Despite a successful completion of the well-doublet experiment, permeability has not been enhanced and CO2 -based heat mining operation is a recommendation that came out to enhance the power production.
