The electric system of Canada’s remote off-grid communities faces several challenges, including high generation costs, limited access to fuel, cold climate, aging diesel generators, high variance of electric demand, environmental risk, limited generation capacity. A variety of solutions exist: each community should leverage on its strengths to develop the most appropriate. In this work a hybrid stand-alone system including hydrogen as energy storage is studied. Such system is applied to two Canadian case studies to see the effect on the levelized cost of energy. The current thesis is divided into five sections. Section one outlines the framework where this work collocates, describes the goal of it and presents a literature review of similar systems.
