“…However, currently the net efficiency of CSP with CaL thermochemical energy storage system from process modelling is from 38% to 46% [64,66], which is slightly lower than that of the commercial CSP with molten salts (40% to 49%) [67]. The auxiliary energy consumption of CO2 compressors account for the major energy penalty of CSP-CaL processes, around 10-14% reduction of the energy efficiency [64,66,68].…”

Energy storage is one of the most critical factors for maximising the availability of renewable energy systems whilst delivering firm capacity on an as-and-when required basis, thus improving the balance of grid energy. Chemical and calcium looping are two technologies which are promising from both the point of view of minimising greenhouse gas emissions and because of their suitability for integrating with energy storage. A particularly promising route is to combine these technologies with solar heating, thus minimising the use of fossil fuels during the materials regeneration steps. For chemical looping, the development of mixed oxide carrier systems remains the highest impact research and development goal, and for calcium looping, minimising the decay in CO2 carrying capacity with natural sorbents appears to be the most economical option. In particular, sorbent stabilisers such as those based on Mg are particularly promising.In both cases, energy can be stored thermally as hot solids or chemically as unreacted materials, but there is a need to build suitable pilot plant demonstration units if the technology is to advance. Highlights Calcium and chemical looping can potentially be deployed at commercial scale within the next two decades. Both technologies have the potential for energy storage, either by means of sensible heat stored in solids or as chemical energy. A critical requirement for such development is construction and testing of suitable pilot and demonstration plants. Both technologies can be combined with solar power to offer particularly attractive systems with thermochemical energy storage.

“…For smallerscale applications, the receiver is integrated with a parabolic trough, enclosed troughs, or Fresnel plants (Al-Juboori and Al-Shawwreh 2018). For larger-scale applications where the receiver is stand-alone, such as a solar tower, CSP plants have shown the most promise for grid-scale applications compared to other systems (Reilly and Kolb 2001;Alnaimat and Rashid 2019;Bielecki et al 2019). At the receiver, the solar energy is either used to create steam to drive a turbine for energy generation or stored as specific heat in a transfer medium to generate energy at a later time.…”

“…At the receiver, the solar energy is either used to create steam to drive a turbine for energy generation or stored as specific heat in a transfer medium to generate energy at a later time. Energy storage allows for smooth power output as well as continuity in energy supply when solar energy is not available (e.g., overnight) (Bielecki et al 2019). In the 1990s, Sandia National Laboratory developed technology that utilized molten salt as the heat-transfer medium (Reilly and Kolb 2001).…”

Electrical energy storage (EES) has emerged as a key enabler for access to electricity in remote environments and in those environments where other external factors challenge access to reliable electricity. In cold climates, energy storage technologies face challenging conditions that can inhibit their performance and utility to provide electricity. Use of available energy storage technologies has the potential to improve Army installation resilience by providing more consistent and reliable power to critical infrastructure and, potentially, to broader infrastructure and operations. Sustainable power, whether for long durations under normal operating conditions or for enhancing operational resilience, improves an installation’s ability to maintain continuity of operations for both on- and off-installation missions. Therefore, this work assesses the maturity of energy storage technologies to provide energy stability for Army installations in cold regions, especially to meet critical power demands. The information summarized in this technical report provides a reference for considering various energy storage technologies to support specific applications at Army installations, especially those installations in cold regions.
