PART 1Executive Overview
1Definition

Green Hydrogen is produced by electrolysis using renewable electricity to split water molecules into hydrogen and oxygen, emitting only water as a byproduct.

2Problem It Solves

It addresses the need for clean energy solutions, particularly for sectors that are difficult to electrify such as heavy industry, long-haul transportation (shipping and aviation), and certain chemical manufacturing processes.

PART 2Technical & Manufacturing
4How It Works

Electrolysers apply an electric current from renewable sources (such as wind or solar) through water, splitting it into hydrogen and oxygen via the electrolysis process. The reaction is: 2H₂O → 2H₂ + O₂. The produced hydrogen can be stored and used for various applications including fuel cells in vehicles or industrial processes.

5Materials Used
6Manufacturing / Creation Process

The production of green hydrogen involves large-scale electrolyser plants which can be standalone or integrated into existing renewable energy infrastructure. The components include electrodes, membranes, and the overall system design for efficiency and durability.

7Build Process

Construction begins with site selection, followed by detailed engineering, procurement, construction (EPC) phase, and commissioning. Key factors in the build process are the availability of renewable energy sources, water supply, and local regulations regarding emissions and safety standards.
