Aquifer Thermal Energy Storage
EFFSYS EXPAND is a research program where industry, academia and government Energy Agency collaborate on research, development and innovation in resource-efficient refrigeration and heat pump systems, refrigeration and heat storage. The total budget amounts to 96 million kronor Energy Agency is contributing SEK 48 million. The program runs over the period 2014-09-01 to 2018-09-01.
EFFSYS EXPAND is a continuation of the previous programs "Alternative refrigerants", "Air 21", "eff-Sys", "Effsys2" and EFFSYS + which together running since 1994. The overall aim of the program is research, development and innovation in refrigeration and heat pump systems as well as cooling and heating bearings contribute to society and the outside world's transition to a more resource-efficient and sustainable energy use and the reduction of environmentally harmful substances in thermal storage and heat pump systems.
The purpose of this project is, through field measurements, test of equipment, calculation and analysis, to quantify the performance and environmental impact of large scale aquifer thermal energy storage, as well as point at recommendations for operating and estimating the environmental footprint of future systems. The following aspects are covered:
-Thermal, chemical and microbiological influence: measurement and evaluation of real conditions and the influence of at least one system in operation.
-Follow up of energy extraction from aquifer as compared to projected values, recommendations for improvements.
-Evaluation of the most used thermal modeling tool for design and calculation of groundwater temperatures. Calculations with MODFLOW.
-Test and evaluation of optical fiber cables as a way to measure temperatures in aquifer thermal energy storages
