Hybrid fuel cell and geothermal resources for air-conditioning using an absorption chiller in Algeria

摘要

This Hybrid Energy System (HES) is mainly based on proton exchange membrane fuel cell (PEMFC) technology, which is supplied by a fuel reforming process for hydrogen production, starting from natural gas. The aim of this paper is to analyse the feasibility study of a process by combining a low-temperature geothermal source with a PEMFC subsystem (PEMFCS). This analysis allows the development of an onsite independent Hybrid Energy System used for air-conditioning, and especially the use of hot water for space cooling. PEMFC technology with an LiBr/H2O absorption system has been introduced to provide fresh air by a cooling process in a school canteen for 240 students, located in the western region of Algeria. The feasibility study shows that combining geothermal sources and PEMFC technology for air-conditioning production constitutes a promising solution.
