Water Electrolysis and Green Hydrogen Production

The Engineer's H2 Handbook is the third book in the Hydrogen Futures series by W. David Jollymore, CEO of Green Electric Power Corporation, written by a practitioner with more than 20 years in hydrogen systems and water treatment operations.

This is the technical deep-dive that engineers have been waiting for. Rather than treating electrolysis as an abstract concept, this handbook examines the real electrochemical science of water splitting — thermodynamics, Faraday's Laws, overpotential, and efficiency losses — then moves into comparative engineering analysis of Alkaline (AEL) and Proton Exchange Membrane (PEM) electrolysis systems, including component design, balance of plant, and real-world system integration. It explains not just what the technology does, but why it behaves the way it does under actual operating conditions.

Designed for engineers, energy professionals, and advanced students entering the green hydrogen production sector who need to understand how to design, evaluate, and specify electrolyzer systems.

Covers: Hydrogen color spectrum, electrochemical fundamentals, thermodynamics of water splitting, Faraday's Laws, overpotential and efficiency losses, Alkaline electrolysis deep dive, PEM electrolysis deep dive, comparative engineering analysis, balance of plant, and real-world system integration.

Prerequisites: Chemistry, basic electrochemistry, and engineering fundamentals. Readers of Books 1 and 2 will have strong preparation.
