Special Issue Information

Dear Colleagues,

In 2020, electricity generation from renewable sources rose ~7%, with wind and solar technologies together accounting for almost 60% of this increase. The share of renewables in global electricity generation reached almost 29% in 2020. Renewable power deployment still needs to expand significantly, as it is the only practical path towards meeting the Net Zero Emissions by 2050 Scenario. The intermittent and non-dispatchable nature of these renewable sources presents a major challenge to power network stability and reliability. The drop in electricity demand caused by the COVID-19 slowdown in economic activity and mobility has further highlighted the need for energy storage technology with longer duration, higher capacity and better cost-effectiveness. Thermo-Mechanical Energy Storage (TMES) systems are based on transformations between mechanical and thermal energy and are particularly well suited to fill in the large capacity, long duration storage gap. Internally, the storage components are combined with components such as heat exchangers, compressors, pumps, or turbines. However, the unique nature of the requirements and operating conditions found in thermomechanical systems often require such commonly used devices to be re-engineered under new performance criteria. Numerous innovative system arrangements and co-generation are also paramount to achieving sufficient grid stability and reliability, as there will not be a “one size fits all” solution to the energy storage challenge. The basic technologies for thermo-mechanical energy storage include: Compressed Air Energy Storage (CAES), Liquid Air Energy Storage (LAES), Power to Heat to Power (PHP) and Carnot battery including Pumped Thermal Energy Storage (PTES).

This Special Issue aims to present and disseminate the most recent advances related to the theory, design, modelling, application, control, economic feasibility and environmental impact of CAES, LEAS, PHP and PTES systems.

Topics of interest for publication include, but are not limited to:

  • Design and optimization of TMES systems and components including, storage devices and technologies, heat exchangers, compressors, and expanders.
  • Low temperature waste heat recovery and integration within TMES systems
  • New designs and strategies for small-scale (kW) applications
  • New designs and strategies for grid scale (MW–GW) applications
  • Integration of TMES systems with renewable sources
  • Fundamental experimental and modelling studies of TMES processes
  • Thermodynamic and techno-economic analyses of TMES
  • Economic, cost, management, and policy assessments regarding TMES

Adiabatic Compressed Air Energy Storage (ACAES) is regarded as a promising, grid scale, medium-to-long duration energy storage technology. In ACAES, the air storage may be isochoric (constant volume) or isobaric (constant pressure). Isochoric storage, wherein the internal pressure cycles between an upper and lower limit as the system charges and discharges is mechanically simpler, however, it leads to undesirable thermodynamic consequences which are detrimental to the ACAES overall performance. Isobaric storage can be a valuable alternative: the storage volume varies to offset the pressure and temperature changes that would otherwise occur as air mass enters or leaves the high-pressure storage. In this paper we develop a thermodynamic model based on expected ACAES and existing CAES system features to compare the effects of isochoric and isobaric storage. Importantly, off-design compressor performance due to the sliding storage pressure is included by using a second degree polynomial fit for the isentropic compressor efficiency. For our modelled systems, the isobaric system round-trip efficiency (RTE) reaches 61.5%. The isochoric system achieves 57.8% even when no compressor off-design performance decrease is taken into account. This fact is associated to inherent losses due to throttling and mixing of heat stored at different temperatures. In our base-case scenario where the isentropic compressor efficiency varies between 55% and 85%, the isochoric system RTE is approximately 10% lower than the isobaric. These results indicate that isobaric storage for CAES is worth further development. We suggest that subsequent work investigate the exergy flows as well as the scalability challenges with isobaric storage mechanisms. Full article

Electrical energy storage systems have a fundamental role in the energy transition process supporting the penetration of renewable energy sources into the energy mix. Compressed air energy storage (CAES) is a promising energy storage technology, mainly proposed for large-scale applications, that uses compressed air as an energy vector. Although the first document in literature on CAES appeared in 1976 and the first commercial plant was installed in 1978, this technology started to gain attention only in the decade 2000–2010, with remarkable scientific production output and the realization of other pre-commercial demonstrators and commercial plants. This study applies bibliometric techniques to draw a picture of the current status of the scientific progress and analyze the trend of the research on CAES and identify research gaps that can support researchers and manufacturers involved in this entering technology. Recent trends of research include aspects related to the off-design, the development of thermal energy storage for adiabatic CAES, and the integration of CAES with combined heating and cooling systems.
