The Zero Emissions Engine is Here

Critical Insight Into Next-Generation Hydrogen Engine Development

The clean energy revolution is no longer on the horizon — it is already here. In The Zero-Emissions Engine Is Here, hydrogen industry veteran W. David Jollymore cuts through two decades of marketing noise to deliver an authoritative, experience-grounded examination of what hydrogen engine technology can actually do, where it genuinely works, and where the industry continues to mislead itself and the public.

Drawing on more than twenty years at the leading edge of hydrogen technology — beginning with electrolyzer development in Aurora, Ontario, and continuing through his role at The Canadian Hydrogen Energy Company — Jollymore brings a scientist's precision and a practitioner's candor to one of the most important technological conversations of our time.

Inside this book you will find:

• A clear-eyed comparison of hydrogen combustion engines and fuel cell technology versus traditional internal combustion engines, including realistic efficiency and emissions data

• A plain-language breakdown of hydrogen production methods — steam methane reforming, electrolysis, and biomass gasification — with honest assessment of their environmental trade-offs

• The real story on HHO combustion enhancement: where it works, where it does not, and why the automotive and trucking sectors are not viable markets despite widespread claims to the contrary

• Comprehensive coverage of hydrogen storage and distribution, including compressed, liquid, and solid-state methods

• An examination of hybrid hydrogen systems and their role in bridging today's infrastructure with tomorrow's clean energy grid

• A forward-looking analysis of the policy, economic, and technical barriers standing between current hydrogen technology and net-zero goals

This book is essential reading for energy students, engineering professionals, technology developers, and investors who need reliable, fact-based insight — not hype — to make sound decisions in the rapidly evolving hydrogen economy.

The zero-emissions engine is not a promise. It is already here. The question is whether you understand it well enough to use it.
