With an increasing share of wind and solar energy in electricity supply, the aspect of load flexibility is gaining importance, i.e., there is an increasing need for buffer capacities and / or power plants must be able to react more flexibly to varying demands. Currently, one option is seen in the construction of new peak-load power plants, e.g. pump storage systems or gas power plants.

Another option could be to use load flexible dust burner technologies to make the supply of, e.g., solar power plants more flexible, i.e. to make them less dependent from solar radiation. By this means, the power supply could be adjusted more effectively to the time-wise varying demand for electricity. With additional employment of locally available regenerative energy carriers, the flexibility of fuel stock could be increased. Hereby, the overall environmental benefit could be increased.

The aim of the project is to develop a hybrid solar / flexible-burner steam turbine power plant.

The goal of the research carried out by ITAS is to identify and quantify the environmental impacts as well as the market potentials of different forms of the concept compared to established technologies. Research will adapt the various instruments common in systems analysis like life cycle assessment (LCA) and life cycle costing (LCC). Based on the results, robust indicators for a successful market entry under the secondary condition of an acceptable environmental balance will be identified.
