Competitive SolAr Power Towers – CAPTure


Developed model library (Modelica modelling language)

The necessary models that allow the performance evaluation of the plant configuration object of this project, will be developed among the partners based on already existing knowledge and model libraries using Modelica language.

Policy workshop

The main objective of this task is to organize a project policy workshop in order to promote the Project’s results towards relevant policy makers at European and national level. Such a workshop will take place towards the end of the Project, once the main results are known, and will take place in Brussels, in order to reach the relevant audience.

System 1-D dynamic model report and open-source model library

A one-dimensional dynamic model of the regenerative system will be developed to simulate its periodic steady state and transient behavior.

CAPTure concept specifications and optimization

One of the aims of the work package related to this deliverable is clearly the optimization of the DSCC plant configuration, in terms of operating strategies, thermal energy storage, field layout, etc. In order to answer the questions above, CEN and EDF will build upon already developed and well proven model libraries and simulation software, and the results of the plant optimization will be written in this report.

Report on ray-tracing algorithm, model development and dynamic aiming strategies

Different dynamic heliostat aiming strategies will be elaborated and evaluated in detail, specifically tailored for the proposed downsized single-facet heliostats, being able to dynamically adapt solar flux distribution smoothing the effect of transient and steady-state conditions on receiver thermal gradients while keeping peak flux on its nominal values, minimizing the spillage and maximizing receiver efficiency. The results will be written in this report.

DSCC concept sustainability (socio-economic and environmental) assessment results and comparisons

Socio-Economic evaluation: Based on the prototype investment as well as operation & maintenance cost data provided by all partners and assuming a large scale deployment of the technology, a socio-economic impact assessment will be conducted. Environmental assessment: sustainability assessments by means of Life Cycle Assessment studies will be carried out. CO2 and other local emissions will be estimated considering system operation and construction (PSA). The results will be presented in a report.

Calibration algorithm report and implementation

The calibration algorithm will be developed and implemented in a chosen programming environment, giving emphasis on an easy implementation at control systems usually applied at real plants. Results will be published in the form of a report and open access articles.

Report on final evaluation of lab-scale and array test results

The solar receiver concepts will be tested on the one hand on module level (e.g. at a solar furnace having a focal spot of 22 cm) and on the other hand on module-array level (at an experimental tower). The analysis and final evaluation of results will be written in this report.

DSCC concept market analysis and business plan report

Today, the DSCC concept has no direct equivalent on the electricity market. The range of levelized cost of electricity for the DSCC concept in different configuration and situation cases will be estimated. In accordance with all contributors, targets for performances and cost will also be defined in order to give a reasonable evolution in the mid-term. Those results will be compared with main technologies or combination of technologies in competition. Standardization activities will be taken into account. All investigation results will be summarized in a comprehensive public report.

Report on model development including detailed model validation

The crucial part of the theoretical consideration of the DSCC concept will be the development of numerical simulation models that allow the performance evaluation of such a plant configuration for typical meteorological input data. The necessary models will be developed and validated among the partners based on already existing knowledge and model libraries, and the results will be written in this report.

Communication material production: website, project visual material, leaflets

This task will be focused on developing the visual identity of the project, which will be discussed during the Kick-off meeting: Refine existing logo, communication templates, website that will be designed in month 1(design, navigation, static content, SEO/SEM strategies), flyer, poster, standard presentations with key messages and one page project description for use by all. Communication material production: website, project visual material, leaflets. M1, M6, M18, M48
