In 2011, renewable energy was responsible for meeting 4 percent of world energy demands. By 2030 this will increase to 13 percent, and the Middle East has a vast potential to meet these renewable energy needs.
Renewable energy generation with wind energy and solar energy
To combat climate change, renewable energy sources like wind power and solar energy are highly important. But if an increasing amount of power is to come from these sources, green energy will have to become more competitive. This can be achieved through wind energy in particular. The innovations that Siemens is currently developing are expected to make electricity generation from wind power a lot more economical.
Our Environmental Portfolio encompasses not only high-efficiency combined cycle power plants but also solutions for wind power and solar energy, power storage units for renewable energy, solutions for smart grids, and high-voltage direct-current (HVDC) transmission.
The Desertec initiative provides renewable energy from the Middle East and North Africa to Europe. The concept encompasses wind power farms, solar thermal power plants, and transnational power highways to efficiently carry the renewable energy to Europe’s load centers.
Renewable energy transmission and distribution
Energy from renewable sources like wind and solar fluctuates depending on the season and the time of day, and smart grids are needed to accommodate these fluctuating power feeds. Smart grids will become increasingly important for stabilizing power networks and ensuring a reliable power transmission and power supply. In the first phase of the visionary Masdar City project, an innovative power grid, combined with advanced and energy-efficient building technologies, will be implemented.
The HVDC transmission system is an efficient, sustainable means of transmitting both conventionally generated and renewable energy over great distances with minimal losses. HVDC minimizes both line costs and losses, thereby lowering the impact on the environment. And it is the only way to interconnect technically incompatible power grids. The Siemens systems are characterized by enhanced reliability, lower energy consumption, and reduced space requirements thanks to laser-pulsed power converters and 80 percent fewer components in the electronic control system. In Saudi Arabia, Siemens will supply technology for the stabilization of the high-voltage transmission network at the Hiteen, Quassim and Afif substations.
Small footprint against climate change
Gas-insulated switchgear (GIS) is another solution that helps to reduce losses in power transmission and save energy. The highly reliable GIS has a small CO2 footprint, short installation times, high resistance to contamination, and minimal maintenance requirements. In the United Arab Emirates, Siemens supplied gas-insulated high-voltage switchgear for an air separation plant in Abu Dhabi. And the Abu Dhabi Transmission & Dispatch Company (Transco) has chosen Siemens equipment for the expansion of the emirate’s electricity grid.
