The Masdar Institute of Science and Technology and Norwegian company NEST AS yesterday announced that the Middle East's first large-scale high-temperature thermal energy storage is now completed at Masdar Institute.

The 1 MWhth demonstration-scale prototype at the Masdar Institute Solar Platform (MISP) is a collaborative project with NEST and other industrial partners. It successfully demonstrates low-cost storage technology for concentrated solar power (CSP) and is considered significant, as solar energy can now be stored in solid state at temperatures up to 400 Celsius at Masdar Institute.

The NEST thermal energy storage (TES) technology is being tested in real solar radiation conditions at the MISP, using hot-oil – the same heat transfer fluid currently used in parabolic trough CSP plants such as Shams-1 in the UAE - to transfer heat to the storage media. This technology allows solar energy to be stored thermally for later use.

Dr. Fred Moavenzadeh, President, Masdar Institute, said, "Thermal energy storage technology is a key part of the renewable energy challenge, particularly in countries like the UAE, where solar energy is plentiful in the day but needs to be stored for use in the night. The TES technology being demonstrated at the Masdar Institute Solar Platform will help contribute to the UAE's renewable energy goals by providing a solution to solar intermittency."

The Norwegian firm NEST is commercialising the system globally. Masdar Institute and NEST are keen to validate this technology and provide proof of concept at demonstration scale. Versatile and scalable, the system is currently testing four solid state thermal energy storage modules. The commercial system is expected to comprise several hundred modules, depending on storage needs, but similar to the ones being tested at Masdar Institute.

Christian Thiel, CEO of NEST, said, "We are delighted by the success of our collaboration with Masdar Institute. We are currently looking at new ways to adapt our TES technology to new renewable energy applications in conjunction with Masdar Clean Energy. Our TES system could also be coupled with CSP for the benefit of sustainable desalination of seawater, which in the UAE currently mainly performed by burning hydrocarbons as part of thermal power and water cogeneration."

Dr. Nicolas Calvet, Assistant Professor, Mechanical and Materials Engineering, is the TES research group leader, and Chair of MISP.
