Abstract

In order to pursue the goals of de-carbonization and renewable sources exploitation, an efficient, cost-effective and environmental friendly employment of energy systems is mandatory. In this context, the ERA-Net funded Project ZEHTC (Zero Emission Hydrogen Turbine Center) has been developed, aimed at the realization of a pilot plant consisting in the world first gas turbine test facility making use of the power produced during turbine tests – along with renewables (solar in particular) – for hydrogen production and batteries storage. The produced hydrogen will be locally used to run the gas turbine, thus reducing its environmental impact. The aim of this paper is to present the results of the first steps of the project, consisting in the definition of an optimized grid and in the development of a calculation model for the optimal energy systems design. To this respect, the typology of energy systems to be included into the grid (in addition to the current set-up of the existing turbine test center) will be presented. In addition, the mathematical models specifically developed for each component, as well as the developed operational logic of the entire grid, will be presented and discussed in order to set the optimal size of each systems.

Summary

Introduction

The current European Energy Roadmap aims at decreasing the continent’s greenhouse gas emissions of a value ranging from 80 % to 95 % by 2050 [1]. In order to increase the contribution of renewables, the hydrogen storage can be considered a solution, being one of the leading options to store energy and looking promising as low-cost option to store electricity over days, weeks or even months [5]. In this context, the aim of this paper is to present the ERA-Net funded Project entitled Zero Emission Hydrogen Turbine Center (ZEHTC) [6], developed by the University of Bologna in collaboration with Siemens. In this paper, the first results of the carried-out analysis will be presented and discussed
