Abstract
In this paper the overall performance of an advanced combined cycle (CC) and of a new advanced mixed cycle (AMC), fed by hydrogen-rich fuel gas, has been evaluated. Obviously, hydrogen must be produced and here we have chosen the partial oxidation of natural gas for its production, quantifying all the thermal and electric requirements. At first, a simple combination between hydrogen production section and power section is performed. In fact, the heat loads of the first section can be satisfied (nearly completely) by using the various raw syngas cooling, but in this case it is not possible to use any part of this heat in the power section. The final result is an overall efficiency of about 44%. Then, by using the Pinch Technology, a more efficient, even if more complex, solution can be conceived; in this case the overall efficiency becomes very interesting especially for the AMC (efficiency is over 50%). This result is very important with the view of a transition toward a "clean energy" economy, based on an energy carrier such as hydrogen.
