Astep Project

ASTEP M30 Physical General Assembly

From October 19th to 21st, 2022, a series of events related to the European project ASTEP (Application of Solar Thermal Energy to Processes) has taken place at the Escuelas Pías building of the UNED’s associate centre in Madrid, Spain.

This project is funded by the European Commission, coordinated by Professor Antonio Rovira from the ETSII of the UNED and involves 15 partners from 8 different countries (Spain, United Kingdom, Cyprus, Italy, Greece, Romania, Poland, and Ireland).

On October 19th, the progress meeting corresponding to the month 30th of project implementation took place where all partners reviewed the progress made and discussed technical and project related matters.

This gave the way to a day of technical workshops and the establishment of networks and collaborations throughout the 20th, which was opened to experts in the field of solar heat generation in the industry.

On the 21st there was a visit to the experimental facilities where the two prototypes are built.

The project began on May 1st, 2020 and aims to adapt the use of the SunDial rotating solar collector (Spanish patent submitted by UNED and Polytechnic University of Madrid) to cover a significant proportion of the demand for heat and cold of the process industry, in locations where the solar resources are easily exploitable and in others where its exploitation is more limited, due to greater latitude and lower temperatures.

SUNDIAL collector designs

The ASTEP project is aligned with the objectives of the European Union established in the Green Deal, zero net balance of CO2 emissions by 2050. Therefore, the consortium faces a series of challenges:

  • Supply heat above current design temperatures and at higher latitudes.
  • Get 24-hour coverage of energy demand.
  • Integrate this design by making minimal changes in the industry and with reduced maintenance requirements.

Two prototypes will be installed in industrial environments, a pasteurization process, generating heat at 175 ºC in Mandrekas, a dairy factory located in Corinth, Greece, and a tube heating process above 220 ºC in ArcelorMittal, a steel factory in Iasi, Romania.


The ASTEP project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 884411.
