Validated model of thermochemical energy storage based on cobalt oxides

摘要: Abstract Thermal Energy Storage (TES) can play a critical role through provision of reliable energy supply and increase the market penetration renewable sources. Thermochemical (TCES) based on reversible reactions offers distinguished advantages in comparison with sensible latent heat storage: higher density, temperature range possibility seasonal storage. TCES systems redox cycle metallic oxides shows significant potential for integration Concentrated Solar Power (CSP) plants using air as transfer fluid, which also acts reactant reaction. A pilot scale thermochemical storage reactor designed CSP plant has been developed tested framework collaborative European funded project “RESTRUCTURE” at Tower Julich (STJ). system is proposed aim achieving capacity temperature. Numerical modeling prototype presented this study contribution towards effort. The present work focused innovative one-dimensional cobalt (Co3O4/CoO), coated ceramics honeycomb structures. numerical model involved balance reaction kinetics describing oxides, to simulate phenomena simulation results were profiles different positions inside vessel they validated against experimental data published literature by other groups. This validation proved that overall process reasonable accuracy. tool was used perform parametric analysis module, provides guidance optimize performance system. Moreover, due its good compromise between reliability computational time, established 1-D be integrated dynamic whole system, study.
