Phase 4: Noor Energy 1 and CSP Technology

The fourth phase of the Mohammed bin Rashid Al Maktoum Solar Park represents a significant technological expansion, introducing concentrated solar power (CSP) alongside traditional photovoltaic (PV) installations. This phase is divided into two primary components: Noor Energy 1, a 700 MW CSP plant, and a 250 MW PV plant. The integration of these technologies aims to enhance grid stability and extend power generation into the evening hours through thermal storage capabilities.

Noor Energy 1: Concentrated Solar Power

Noor Energy 1 is the world’s largest single-site CSP plant, with an installed capacity of 700 MW. The facility utilizes solar power tower technology, which employs thousands of heliostats to reflect and concentrate sunlight onto a central receiver located at the top of a tower. This concentrated solar energy heats a working fluid, typically molten salt, which stores thermal energy. The use of molten-salt storage allows the plant to generate electricity even after sunset, providing a dispatchable power source that complements the variable output of PV panels. The CSP plant is designed to operate for approximately 15 hours a day, significantly extending the solar park's daily generation profile.

Photovoltaic Component

In addition to the CSP facility, Phase 4 includes a 250 MW photovoltaic plant. This PV installation uses standard solar panels to convert sunlight directly into electricity. The combination of 700 MW of CSP and 250 MW of PV in this phase brings the total capacity of Phase 4 to 950 MW. This hybrid approach leverages the strengths of both technologies: the high capacity factor and storage capability of CSP, and the lower levelized cost of energy associated with PV. The phase is a critical step toward the solar park’s ultimate goal of reaching a total capacity of 5,000 MW, contributing substantially to the United Arab Emirates' renewable energy targets.

How does the CSP technology work?

Concentrated solar power (CSP) technology converts sunlight into electricity through thermal energy storage and mechanical generation, distinct from the photovoltaic (PV) panels that dominate earlier phases of the Mohammed bin Rashid Al Maktoum Solar Park. The system relies on mirrors to focus solar radiation onto a receiver, heating a fluid that drives a turbine. This approach allows for dispatchable power generation, enabling the plant to produce electricity even after sunset, a critical feature for grid stability in the United Arab Emirates.

Parabolic Trough Systems

One of the primary CSP technologies employed involves parabolic troughs. These systems consist of long, curved mirrors arranged in parallel rows. Each mirror is shaped like a parabola, designed to reflect and concentrate sunlight onto a receiver tube positioned along the focal line of the curve. The receiver tube contains a heat transfer fluid, typically synthetic oil or molten salt, which absorbs the concentrated solar energy. As the sun moves across the sky, the troughs rotate on a single axis to maintain optimal alignment with the solar radiation.

The heated fluid is then pumped through a heat exchanger to produce steam. This high-pressure steam drives a conventional steam turbine connected to a generator, producing electricity. The thermal inertia of the fluid allows for some degree of energy storage, meaning the system can continue generating power for several hours after the sun sets, depending on the capacity of the thermal storage system. This technology is well-suited for the vast, flat terrain of Saih Al-Dahal, maximizing land use efficiency within the 77 km2 area of the solar park.

Solar Power Towers

The solar power tower technology represents a more complex approach to concentrated solar power. In this configuration, a large field of flat or slightly curved mirrors, known as heliostats, tracks the sun in two axes. Each heliostat reflects sunlight toward a central receiver located at the top of a tall tower. This concentration of solar flux can achieve significantly higher temperatures compared to parabolic troughs, often exceeding 500°C to 600°C.

The receiver absorbs the concentrated solar energy and transfers it to a heat transfer medium, frequently molten salt due to its high thermal capacity and stability at high temperatures. The heated molten salt is stored in insulated tanks, providing substantial thermal energy storage. When electricity is needed, the hot salt is pumped through a steam generator to produce steam, which drives a turbine-generator set. This technology offers high efficiency and excellent storage capabilities, making it a key component in achieving the park’s goal of providing consistent, baseload renewable energy to Dubai’s grid.
