Developed detailed economic models, for mass storage of electricity in European markets

WP3 was aimed at establishing the thermo-economic requirements for AA-CAES. As part of that work, detailed economic models were prepared with the following characteristics: - The GEMS model - is an investment and dispatch model of the German power generation system. It covers cost-minimising techniques applicable to both long-term investment decisions, and short-term operation. - The GEMS-CHP model - is an adaptation of the GEMS model for the Dutch power generation system. It particularly excludes power generation from lignite plant and from pumped hydro storage, but notably includes combined heat and power generation. - The DIMEX model - is a linear optimization model which maximizes the yearly profit contribution of plant operation taking into account both technical constraints and economic parameters. The model delivers the optimum plant dispatch and the resulting obtainable revenues. The models currently address particular markets. However, the fundamental approach of these models can be applied to any power generation mix, and therefore any market.

Established improved measurements of thermophysical properties of humid air, made available (together with literature results) via on online database

WP4 was aimed at establishing an extensive and reliable database of experimental data, and calibrated models on the thermodynamic and transport properties of humid air. The following issues have been addressed: - Generation of Experimental Reference Data - generation of reference thermodynamic data at homogeneous and saturated states. Generation of reference transport data, viscosity and the thermal conductivity of humid air at high pressures. - Development of a Data Base - established a database of experimental literature data. - Development of Models - established models calibrated with the experimental reference data for thermodynamic and transport properties of humid air. Whilst it is expected to exploit the experimental data within international standardisation activities (IAPWS), the experimental facilities and modelling capabilities of each contractor are expected to be of interest to other organisations (principally gas turbine, steam turbine manufacturers) requiring the properties of humid air.
