Thermochemical heat storage at high temperature
2021Implementation of cost-effective thermal energy storage systems is one of the signature advantages of concentrating solar power (CSP) plants. Currently these components are based on sensible heat storage in molten salts, but those compounds start to decompose below 600 °C.

Thermochemical heat storage materials – Performance of mixed salt hydrates
Solar Energy, 2016Abstract Thermochemical heat storage is highly promising, in particularly with a view to long-term heat storage. For the implementation of heat storage in households, thermochemical reactions in the low temperature range below 120 °C are important. Especially salt hydrates such as MgCl2, CaCl2 or MgSO4 were tested with micro gravimetric methods for ...

Topology optimization for heat transfer enhancement in thermochemical heat storage
International Journal of Heat and Mass Transfer, 2020Abstract Thermochemical heat storage has a promising application prospect due to its high energy density and ability of seasonal energy storage with little heat loss. However, most of thermochemical heat storage systems suffer from very poor thermal conductivity that limit the heat transfer rate and hinder the implementation of this technology.

Thermochemical heat recuperation for compressed air energy storage
Energy Conversion and Management, 2021Abstract Compressed Air Energy Storage (CAES) suffers from low energy and exergy conversion efficiencies (ca. 50% or less) inherent in compression, heat loss during storage, and the commonly employed natural gas-fired reheat prior to expansion. Previously, isothermal, and adiabatic (or ‘advanced’ adiabatic) compressed air energy storage have been ...

Residual Heat Utilisation in Vehicles by Thermochemical Energy Storage
MTZ worldwide, 2015Climate protection projects of the European Union provide a gradually reduction of CO2 emissions from new cars in the next years. The targets caused so far numerous measures which resulted in an improved efficiency of new vehicles. As part of the search for further improvements the utilization of residual heat gets increased into focus. For this reason

Non-equilibrium thermochemical heat storage in porous media: Part 1 – Conceptual model
Energy, 2013Abstract Thermochemical energy storage can play an important role in the establishment of a reliable renewable energy supply and can increase the efficiency of industrial processes. The application of directly permeated reactive beds leads to strongly coupled mass and heat transport processes that also determine reaction kinetics.
