An Essential Guide to Fuel Cells, Water Electrolysis, and the Clean Future of Power
Hydrogen is no longer a technology of the future. It is being deployed right now — in industrial plants, transportation fleets, and power grids around the world. The engineers, policy makers, and students who understand it will shape the energy economy of the next fifty years. The Engineers H2 Handbook cuts through the noise and delivers the technical foundation you need to work confidently with hydrogen systems.
Written by W. David Jollymore — CEO of GreenElectric Power Corp and a veteran of more than 25 years in hydrogen research, fuel cell development, and environmental technology — this handbook bridges the gap between classroom theory and real engineering decisions.
Inside You’ll Find
A clear explanation of the Hydrogen Colour Spectrum — Grey, Blue, and Green — and why it matters for project economics and environmental impact. The complete science of water electrolysis, including thermodynamics, electrochemistry, Faraday’s Laws, and efficiency calculations explained in plain engineering language.
A deep dive into Alkaline Electrolysis (AEL) — operating principles, component breakdown, balance of plant, performance characteristics, and real limitations — alongside Proton Exchange Membrane (PEM) Electrolysis, including the critical iridium supply chain risk every project engineer needs to understand. A head-to-head comparative analysis of AEL vs. PEM, with a practical decision framework for choosing the right technology for a specific project.
Real-world application case studies, including industrial ammonia production and a hydrogen-powered forklift fleet deployment. Next-generation technologies — Anion Exchange Membrane (AEM) and Solid Oxide Electrolysis Cells (SOEC) — explained clearly, plus a full glossary of hydrogen engineering terms.
Who This Book Is For
Engineers designing or evaluating electrolysis-based hydrogen systems. Policy makers who need technical literacy to make sound energy decisions. University students in energy, chemical, and mechanical engineering programs.
Whether you’re designing your first electrolyzer system or evaluating hydrogen as part of a national energy strategy, this handbook gives you the engineering judgement to make the right decisions. This is not a book about the future of hydrogen. It is a guide to building it.
