The GT26 and GT24 gas turbines offer greater flexibility to suit today's dynamic power markets like the UK. Improved fuel flexibility, flexible operation modes, and unique low load operation capability are achieved through sequential combustion, says Alexander Bill, service manager at Alstom's Power Division.
Deployment of carbon capture storage (CCS) technology will allow for more coal and gas to be used than without CCS, Sean McCoy, analyst at the International Energy Agency (IEA) told Gas to Power Journal.
"More than two thirds of today's fossil fuel reserves would have to remain un-burnt and in the ground in the absence of CCS," he said referring to the IEA's World Energy Outlook 2012.
Norwegian oil and gas major Statoil has selected Siemens' PostCap process for phase-3 in the technology qualification program for the carbon capture and storage (CCS) plant at the combined-heat and power plant at the refinery in Mongstad. The final phase of the qualification process will come to an end in April 2013.
The F-class turbine fleet is now mature and of the right size to interest third party part and service providers, says Intergen manager for project development engineering, Kevin Baker. Intergen has terminated a maintenance support contract with an original equipment manufacturer (OEM) and tendered for a third party provider to service one of its power plants.
Carbon capture reduces the efficiency of the combined-cycle gas turbine power plant (CCGT) by 11%-point, a study by Sari Siitonen, Gasum Oy and Leena Pirhonen ÅF-Consult shows. The study analyses how the integration of pre-combustion carbon capture technology in the gas-fired combined heat and power (CHP) plant affects the efficiency, power-to-heat ratio, CO2 emissions and costs of the power plant.
Future gas turbine research and development (R&D) needs to focus on a 'big is beautiful' approach to developing smaller, flexible units that can run efficiently at part-load, OEM representatives from Alstom, GE, Mitsubishi HI, Siemens and Pratt & Whitney Power Systems agreed at a conference in Brussels today.
Singapore is building three new large combined cycle plants to cater for the city state's growing electricity demand.
"The selection of combined cycle plants based on GT26 advanced gas turbines for all three of these projects indicates the importance of high plant flexibility while maintaining high efficiency and low emissions in many of today's electricity markets," says Pascal Radue, regional vice president, Alstom Gas Business, Asia.
GE will supply eight gas turbine-generators for the expansion of Saudi Electricity Company's (SEC) Riyadh Power Plant 12 (PP12). Once operational in 2015, the combined-cycle plant will be the first application of GE's 7F-5 series gas turbine technology in Saudi Arabia, adding nearly 2,000 megawatts of electricity to help meet the Kingdom's future energy demand.
RWE's decision as to which gas turbine vendor to use for its newly opened Pembroke Power Station has been largely driven by Alstom's service agreement, according to Andy Smith, project development manager at RWE.
"In the UK, the market for building new combined-cycle plants is EPC-based and we were therefore exposed to the equipment choices that the different turbine manufacturers have on offer," he told Gas to Power Journal at a conference organised by the publication in London.
