Hydrogen: Properties, Thermodynamics and Electrochemistry Presentation

This presentation explores the key properties of hydrogen and how these relate to its potential as a fuel and its role in the transition to net zero. It introduces hydrogen’s physical and chemical properties, including its low density, high reactivity and flammability, before examining its thermal and energy characteristics. The presentation also considers the differences between gaseous and liquid hydrogen, explaining how liquid hydrogen is produced and why it can be advantageous for certain applications, such as rocket fuel.

The presentation then introduces key concepts in thermodynamics and electrochemistry through hydrogen-based examples. Learners explore Hess’s Law and enthalpy changes, Gibbs free energy and spontaneous reactions, and how energy input enables non-spontaneous reactions such as water electrolysis. By connecting these concepts to hydrogen production and use, the presentation builds an understanding of the scientific principles underpinning hydrogen technologies and their importance in a future low-carbon energy system.
