Marcegaglia for the world’s largest solar concentration plant

Marcegaglia Specialties contributes to the construction of the largest single site CSP (Concentrating Solar Power) plant in the world.
This is the Noor Energy 1 Project, the fourth phase of development of the Mohammed Bin Rashid Al Maktoum Solar park in Dubai, United Arab Emirates.
The project, with a total cost of $3.9 billion, includes 700 MW from CSP technologies and 250 MW of photovoltaic power generation. Once completed, it will provide clean energy to more than 320,000 homes in Dubai, reducing carbon emissions by 1.6 million tons per year.
Developed by Acwa Power in close cooperation with DEWA (Dubai Electricity & Water Authority), Shanghai Electric Group Corporation as EPC and Abengoa Energía as solar field technology provider, the system will use Rioglass Solar technology with linear parabolic collectors that concentrate sunbeams in receiving tubes linearly developed and positioned in its focus. The collectors are designed to follow the motion of the sun along an axis, which moves in a north-south direction.
Through the collaboration with Metaltubi (Eusider group), Marcegaglia Specialties supplies a share of the 6,000 tons of stainless steel tubes used to make the plant’s collectors.
The tubes are supplied to Rioglass Solar, which reworks and covers them with several layers of materials that absorb solar radiation, then they are encapsulated within other larger glass tubes. Inside the stainless steel tubes flows the thermo-vector fluid, which produces steam at high temperatures, through a series of heat exchangers. The steam is then converted into electricity by a turbine.
Thanks to the experience acquired in the Noor 2 CSP complex in Ouarzazate (Morocco) and in the Kathu Solar Park plant, located near Kathu (Northern Cape, South Africa), Marcegaglia confirms itself as a world-class partner for the solar thermodynamic sector.
