Project CAPTure “Competitive SolAr Power Towers”. (H2020-LCE-2014-1. Grant Agreement Nº: 640905) (2015-2019)

  • Main objective: The main objective of this project is to significantly reduce costs of concentrated solar power, in order to pave the way for its deserved competitiveness on the power market. The global objective of this project is to increase plant efficiencies and reduce levelized cost of electricity (LCOE) by developing all relevant components that allow implementing an innovative plant configuration. This plant configurations is based on a multi-tower decoupled advanced solar combined cycle approach that not only increases cycle efficiencies but also avoids frequent transients and inefficient partial loads, thus maximizing overall efficiency, reliability as well as dispatchability, all of which are important factors directly related to cost competitiveness on the power market .CENER is the coordinator of this European project. The main activities which will be carried out within this project are the following:
    • WP 1: DSCC – The modular multi-tower decoupled solar combined cycle concept.
    • WP2: Solar receiver
    • WP 3: Regenerativeheatexchangesystem
    • WP 4: The solar-driven Brayton cycle
    • WP 5: Solar field
    • WP 6: System integration and testing in the relevant environment
    • WP 7: Riskanalysis
    • WP 8: Dissemination of results and communication
    • WP 9: Exploitation of results
    • WP 10: Project management and coordination

Tonatiuh Project

The Tonatiuh project aims to create an open source, cutting-edge, accurate, and easy to use Monte Carlo ray tracer for the optical simulation of solar concentrating systems. It intends to advance the state-of-the-art of the simulation tools available for the design and analysis of solar concentrating systems, and to make those tools freely available to anyone interested in using and improving them. Some of the most relevant design goals of Tonatiuh are:

  • To develop a robust theoretical foundation that will facilitate the optical simulation of almost any type of solar concentrating systems.
  • To exhibit a clean and flexible software architecture, that will allow the user to adapt, expand, increase, and modify its functionalities with ease.
  • To achieve operating system independence at source level, and run on all major platforms with none, or minor, modifications to its source code.
  • To provide the users with an advanced and easy-of-use Graphic User Interface (GUI).
