Client European Commission, 7th FP

Overall Cost 0.786M€

POP 2014-2017

Project Description

Project Summary

The project focusses on the loop involving conversion from high flux solar to thermal energy, including the storage system needed to optimize dispatch on demand for further use of energy in the production of electricity, solar fuels or chemicals. This intermediate system, located in between the solar field and the power block, encompasses the solar receiver, the heat transfer fluid with thermal loop and the thermal energy storage:.

REELCOOP
Research Cooperation in Renewable Energy Technologies for Electricity

Client European Commission, 7th FP

Overall Cost 7.476 M€

POP 2013-2017

Project Description

Project Summary

The overall aim of REELCOOP will be to significantly enhance research cooperation and knowledge creation on renewable electricity generation, involving Mediterranean partner countries (MPC), while at the same time developing and testing new renewable electricity generation systems. REELCOOP will develop decentralized (distributed) building integrated PV systems and Solar Thermal /biomass micro-cogeneration systems, as well as centralized generation of electricity in hybrid concentrating solar & biomass power plants.

Thermal Storage Group’s Role

CIEMAT is developing its new patent for a latent storage module for low-k PCM and spiral-based geometry. This spiral-based latent storage is expected to be an alternative to fin-configuration for medium-low storage capacities

Technical Approach and Resources Used

The research team is engaged in

  • Analysis, modeling and simulation of the new latent storage geometry.
  • Design and construction of a prototype module based on spiral concept.
  • Testing and evaluation of this prototype.
  • Design optimization.
  • Analysis and optimization of control strategies of this TES prototype with a parabolic trough field and an organic Rankine cycle.

Project Results (including any commercial outcomes)

Three novel prototype systems will be developed and tested, which will be representative of both micro (distributed) and large (centralized) scale approaches to electricity generation. The environmental sustainability and economics of the prototype systems will be assessed, and the results obtained will be disseminated to industry and research, as proof-of-concept
of renewable electricity generation solutions. Grid integration will also be assessed.
