Dr. Nicolas Calvet is an assistant professor at Khalifa University of Science and Technology in Abu Dhabi, United Arab Emirates (UAE) since 2013.  He is the founder and chair of the Masdar Institute Solar Platform, the first R&D platform in the UAE entirely dedicated to concentrated solar power (CSP) and thermal energy storage (TES).  Finally he is representing the UAE at the SolarPACES Executive Committee, a technology collaborative program from the International Energy Agency (IEA).

Dr. Calvet has a BS in Physics, and a M.S. in Solar Energy from the Université de Perpignan Via Domitia (UPVD) in France.  Then he obtained his Ph.D. in Engineering Science (Energy and Environment) in 2010 at the PROMES CNRS Laboratory in France.  In 2011, he joined the National Renewable Energy Laboratory (NREL) in USA working in the CSP group.  In 2012, he worked at the CIC Energigune Energy Cooperative Research Centre in Spain in the TES group before moving to Abu Dhabi.

Recent Research Projects

  • The Masdar Institute Solar Platform (MISP), Sponsor Khalifa University , 2013-now.

First platform in the UAE dedicated to Concentrated Solar Power & Thermal Energy Storage Research & Development.  The objective is to attract local & international collaborations and test sytems or components in harsh desert environment.

  • ASC-10 Project” (Sponsor: Wahaj Solar (Wahaj Investment LLC, Dubai), Principal Investigator: Dr. Nicolas Calvet, 2019-2020.

Development of a new type of “Beam through” solar concentrator. ASC-10 is a metallic reflectors based Fresnel Lens of 10 meters in diamter that can achieve high flux (1000 suns) and high temperature (1000 °C) with a focal point fixed to the ground.  Applications are numerous: 24/7 off-grid solar power, solar process heat, solar desalination, or solar fuels production, etc.


  • “Stirling engine with integrated thermal energy storage” (Sponsor: Azelio AB (Sweden), Principal Investigator: Dr. Nicolas Calvet, 2019-2021.

The objective of this project is to demonstrate Azelio’s thermal energy storage technology in Masdar City (50 kWe 24/7).  The system is using a phase change material (PCM) to store thermal energy as latent heat.  It can be used for renewable energy (PV, wind, or CSP) or as a Carnot Battery for excess grid electricity or in conventional power plants.
