Book excerpt: Power to Fuel: How to Speed Up a Hydrogen Economy highlights how the surplus of electricity from renewable sources can be usefully accumulated thanks to hydrogen overcoming the obstacles that can prevent the final use of hydrogen on a large scale. The book includes an introduction and sections on the production of hydrogen, conversion of hydrogen into synthetic fuel, the power-to-fuel concept, and renewable energy source descriptions. The second and third levels are structured identically with a standalone approach that covers established and commercial pathways, emerging pathways, and cost analysis sections within each subject specific chapter, making the content easily referenced and applied.Readers will find details on the state-of-the-art and emerging technologies of various power to fuels options suitable for different final uses of the stored energy, as well as figures and diagrams that illustrate and compare the different processes. The book contains examples of existing plants and pilot projects that will be useful for academics dealing with renewable energies and energy storage. - Discusses possible applications of synthetic fuels, describing existing plants for fuel production - Contains opinions on opportunities offered by the power to fuel concept and by single technologies - Presents power to fuel techno-economic models and calculations down to system level
