Design eines Luftenergiespeichersystems
To improve the continuous storage capacity and economic viability of LAES, this paper proposes two enhanced processes, dual-compression LAES and medium-pressure
Which energy storage technologies are suitable for grid-scale energy storage?
Currently, two technologies – Pumped Hydro Energy Storage (PHES) and Compressed Air Energy Storage (CAES) can be considered adequately developed for grid-scale energy storage [1, 2].
What is a liquid air energy storage system?
Further analysis of dynamic conditions should be done, with the aim of identifying any potential design implications. Liquid Air Energy Storage (LAES) systems are thermal energy storage systems which take electrical and thermal energy as inputs, create a thermal energy reservoir, and regenerate electrical and thermal energy output on demand.
What are the different types of energy storage technologies?
Energy storage technologies can be classified into four main categories – mechanical energy storage (e.g. compressed air energy storage, pumped hydro energy storage), electrical energy storage (e.g. capacitors), thermal energy storage (e.g. liquid air energy storage), and chemical energy storage (e.g. lithium batteries, fuel cells).
Can LAEs be a competitive energy storage technology?
LAES systems have the potential to be a competitive local and grid scale energy storage technology. LAES systems can facilitate the penetration of renewable energy technologies. Further analysis of dynamic conditions should be done, with the aim of identifying any potential design implications.
Which thermal energy storage materials are suitable for LAEs?
Thermal energy stores and storage media Numerous studies can be found in the literature on thermal energy storage materials, devices, and system integration, but not all are suitable for LAES. Compression heat store and storage media Water, thermal oil and solid particulate are among the main TES materials for storing compression heat.
What is the exergy efficiency of LAEs system?
The exergy efficiency of the LAES system is also improved by approximately 28%. Lee et al. analysed systems where power is produced by direct and indirect methods of LNG direct expansion and organic Rankine cycle, claiming an LNG-ORC-LAES RTE of 122.8% and an LNG-LAES RTE of 105.6%.
