“Hydrogen-based Autonomous Power Systems” analyses the introduction of hydrogen energy technologies in autonomous power systems based on renewable energy sources (RES). The book contains a review of hydrogen technologies suitable for RES-based autonomous power systems, presents already-existing demonstration hydrogen-based power systems, and provides concrete examples for the integration of hydrogen technologies into existing autonomous power systems. Technical and economic analyses of hydrogen-based power systems are included, with illustrations and graphs, which are a useful tool for conducting pre-feasibility analyses of such power systems. The book is a valuable resource for researchers and students in the fields of hydrogen energy technologies, renewable energy power systems, and distributed generation.
