MULTISTOR: Design of multifunctional redox systems based on mesoporous transition metal oxides for thermochemical energy storage

Research project corresponding to the call 2012 and reference: ENE2012-36937, within of the Subprogram of fundamental not-oriented research of the National Plan of Scientific Research, Development and Technological Innovation 2008-2011.

The future of the energy systems will surely include the extensive deployment of different renewable sources, which according to mandate of the European Commission should constitute at least 20 % of the generated power by 2020. In order to achieve this objective, significant improvements of the currently available technologies are warranted. In this scenario, it is particularly relevant the development of system for energy storage in order to account for the intermittency of the renewable sources. In particular there is a clear demand of new efficient and reliable systems for thermal storage at high temperature (500-1000 ºC range) in order to fully exploit the potential of concentrating solar plants (CSP). Besides there is also a need of more efficient systems for using abundant renewables resources such as biogas and taking full advantage of their capacity for reducing CO2 emissions. In this context, the present proposal is intended to develop thermochemical storage systems based on mesoporous transition metal oxides (CuO, Co3O4, Mn2O3, Fe2O3…) either in bulk form or supported on thermally stable supports(SiC,, ZrO2…) with ability for storing energy as either heat or chemical carriers. For this goal the use of advanced synthetic routes such as nano-template fabrication techniques it is proposed.

The main objective of the project would be to develop a stable and economically viable system with ability to operate efficiently in both processes, providing a flexible alternative for thermochemical storage that could be adapted to the production of heat or CO2-free hydrogen.
