An inexhaustible source
Concentrated solar thermal power is worldwide becoming a more and more important source for power generation. The reasons for this are obvious: The sun is an inexhaustible source for power production. And it is not only a free fuel source but also a complete emissions-free source. Steam turbine generator sets convert solar energy into electricity. Instrumentation and controlls help to make optimal use of every single sun beam. We equipped more than 70 CSP plants all over the world and we are the market leader in that field.
DEWA builds region's first solar-driven hydrogen electrolysis facility
Seeking to place its energy system and its national economy on a more sustainable footing, the government of Dubai and its state utility DEWA have decided to push ahead with the integration of H2 technology and accelerate the use of renewables in the region. To this end, DEWA and Siemens Energy are building the region’s first solar-driven hydrogen electrolysis facility at Mohammed bin Rashid Al Maktoum (MBR) Solar Park in Dubai.
The right equipment for every CSP technology
Since the solar boom of the eighties in USA, solar thermal energy has been a proven technology. The most common type of plant is the parabolic trough collector, but alternative technologies are rapidly coming to the fore, such as Linear Fresnel collector plants with flat mirrors and central tower plants with slightly curved mirrors or heliostats.The basic principle is the same for all three plant technologies: Mirrors concentrate the incident solar radiation onto a receiver where it is converted into heat that is used to produce steam to drive a steam turbine. Heat storage systems like molten salt tanks provide for power supply even during unfavorable weather conditions or at night. They significantly increase the number of full-load operation hours with optimal steam turbine efficiency.
Turbines for all main CSP technologies
With our broad steam turbine portfolio,we offer a range of turbines for different types of solar plants and all power outputs. The turbine technology fits all three common concentrated solar power concepts. We were the first steam turbine supplier to re-enter the CSP market in the 21st century, pioneering commercial solutions in the US and Spain. Today, we are the world market leader in steam turbines for CSP plants, and have more than 20 years of experience with steam turbines for daily cycling.
Typical regimes of operation
The number of concentrated solar power plants has increased tremendously in the past ten years. Today we see many different regimes of operations, each of which poses a different challenge to power generation equipment. The design of each steam turbine is adapted to these challenges.Examples for the regimes of operation for a solarthermal power plant, with a power output of 50 MW:
Dispatchability with instrumentation and controls
We provide optimal instrumentation and controls (I&C) design for CSP & Hybrid-PV plants for achieving the full dispatchability of solar energy power plants. With start-up and shut-down 365 days a year, high demands are placed on your plant even on the sunniest of days. Thanks to our I&C’s integration expertise in steam turbine controls, balance-of-plant, and solar fields the plant’s performance is optimized and long-term reliability is maintained.
With the Digital Enterprise solution portfolio, we offer all the controller and drive components necessary for turning good ideas into even better system solutions under one roof – for the entire range of solar production machines and solar trackers.
Industrial steam turbines – tailor-made and flexible
As a market leader for industrial steam turbines, we offer a comprehensive range of reliable and versatile steam turbines for the power output range from 2 to 250 MW. Our industrial steam turbines are designed for easy constructability, fast start-up and economical operation.
