Realistic comparison of fossil fuelled power plant processes

Simulation model for gas- and coal-fired power plants developed

Gas- and, in particular, coal-fired power plants will have to become more efficient and produce fewer emissions in order to compete in the future energy mix. They will be needed to ensure the stability of the electricity grid for several years by balancing out the electricity generated from renewable energies, which fluctuates according to the time of day and season. The recently published BINE-Projektinfo brochure "Comparison of electricity production from fossil fuels" (05/2011) presents simulation models for making realistic and standardised comparisons of modern, fossil-fuelled power plant processes. The research work was conducted at the Hamburg-Harburg University of Technology.

Various technological development approaches are competing within fossil fuelled power plant processes to achieve the best values in regard to energy efficiency and carbon dioxide emissions (CO2). Power plants based on lignite, hard coal and natural gas can be combined with one of three processes for capturing and storing CO2 (CCS technologies). These enable the CO2 emissions released into the atmosphere by fossil-fuelled power plants to be dramatically reduced. Higher temperatures and greater pressure also help to increase the efficiency of power plants, as do new materials and optimised gas turbines. The simulation models developed in Hamburg are based on a standard of 1,100 MW for steam power plants with 72 defined parameters. 30 parameters had to be specified for gas turbines.

The ability to realistically compare the efficiencies and emission figures for the various power plant processes will help determine the roles to be played by natural gas and coal in the future energy mix.
