Fossil fuels and renewable energy in sustainable energy generation
The future of sustainable energy generation lies with a balanced power mix of increased renewable energy generation combined with using fossil fuels more efficiently.
Sustainable energy mix of fossil fuels and renewable energy
Our world still relies heavily on the Middle East’s fossil fuels. Over the next twenty years, fossil fuels will meet two thirds of global power demand. However, with diminishing fossil fuel resources, it is important to establish a supply of alternative energy. And while renewable energy sources like wind energy are important for sustainable energy generation, oil and gas will still be required to ensure the reliability of smart grids, in order to compensate for the fluctuations of renewable energy.
While Siemens offers a range of renewable energy solutions, including wind energy generation, it also offers solutions for highly-efficient combined cycle power plants, to boost the efficiency and reliability of the oil and gas industry, as well as solutions for smart grids, and high-voltage direct-current (HVDC) transmission.
Efficiency in the oil and gas industries
As a leader in climate protection technologies, Siemens offers cutting-edge solutions to help make power generated from fossil fuels like oil and gas more efficient and sustainable. We provide onshore and offshore applications in the oil and gas industries. Our energy-efficient products and solutions help our customers improve their business performance, reduce lifecycle costs, and cut CO2 emissions. In 2011, Siemens and Aramco agreed to strengthen their long lasting cooperation for the efficient use of fossil fuels in Saudi Arabia. The cooperation covers low-emission gas turbines and high-efficiency steam turbines, granting Saudi Aramco improved access to Siemens Oil & Gas Division’s rotating equipment and services.
Combined cycle power plants and more efficient power generation methods
A combined cycle power plant (CCPP) is among the most efficient power generators fired with fossil fuels. They combine a gas turbine with a steam turbine to produce twice the energy yield from the fossil fuels they consume, enhancing overall energy efficiency by up to 60 percent. Siemens has built two combined cycle power plants in Oman. Since May 2012, Barka III and Sohar II have been in operation in simple cycle mode, with the extension to combined cycle to follow. In Kuwait, the Az-Zour combined cycle power plant from Siemens helps to ensure the reliability of the country’s power supply. And in Saudi Arabia, Siemens will supply the key components for a major combined-cycle power plant. It is designed to deliver electricity to the Jazan industrial area in the southwest of the country and to the refinery of Jazan, which will additionally be supplied with process steam. The plant will be fueled with gasified refinery residues, which contributes greatly to the preservation of the country’s energy resources. With an installed capacity of 4,000 megawatts, Jazan will be the largest gasification-based power plant site in the world.
Shuweihat combined cycle power and desalination plant
In Abu Dhabi, Siemens erected Shuweihat, the most efficient combined cycle power plant and desalination facility in the world. The turnkey project can generate approximately 5,000 megawatts of electricity and 1.4 million cubic meters of drinking water daily – an important amount in a country where water is very scarce. As a follow-up order, Siemens is building the turnkey combined cycle power plant Shuweihat S3. The scheduled start of operation is in 2014.
Combined heat and power (CHP) plants offer even greater energy efficiency. They convert fossil fuels into electrical energy and heat at the same time. These plants can achieve efficiency levels of more than 90 percent. The number of CHP plants in the Middle East is set to increase, with a further 11 percent of power to be generated by CHP plants by 2030, up from 29 percent at present. Projects like this are particularly important, with the region’s rapidly increasing population levels. Siemens technology is able to improve power station efficiency and help the Middle East meet targets with its comprehensive portfolio of sustainable energy solutions, including sustainable power transmission.
