So, for each heat source the following specifications are needed: Annual heat input for storage Heat input profiles (monthly, weekly, daily, hourly) Heat input temperature profiles (monthly, weekly, daily, hourly) Note: Heat source (store input) might depend on the weather – e.g. input from a solar collector field
In Bakema & Drijver it is further highlighted that a rule of thumb for the demand side is a required thermal input of at least 5 MW in order to reach an acceptable storage efficiency. Compared with low-temperature ATES systems (LT-ATES) the capacity ranges between 0.1 and 0.3 MW for small-scale and between 5 and 30 MW for large-scale systems27.
heat, which varies over time. As a result, the flow rate and the pump direction of the heat storage system also varies over time. Due to the fluctuating pump regime (mainly pumped back and forth in the mid-season) the average storage period will in reality be somewhat shorter than half a year.
In order to meet economical requirements, a MTES needs to be operative in the range of 40 to 50 years. Depending on the utilized heat source and its application, different heat capacities, mass flows and temperature levels would be encountered within the mine thermal energy storage.
The main objectives of the HEATSTORE project are to lower the cost, reduce risks, improve the performance of high temperature (~25°C to ~90°C) underground thermal energy storage (HT- UTES) technologies and to optimize heat network demand side management (DSM).
Low carbon heat sources (e.g. geothermal, biomass, solar and waste-heat) need to be deployed and heat storage plays a pivotal role in this development. Storage provides the flexibility to manage the variations in supply and demand of heat at different scales, but especially the seasonal dips and peaks in heat demand.
