What is White Hydrogen

About White Hydrogen

• White hydrogen is also referred to as “natural,” “gold” or “geologic” hydrogen.
• It is naturally produced in the Earth’s crust and is considered a potential source of clean energy.
• It generally exists combined with other molecules.
• White hydrogen has several advantages over other types of hydrogen
  • It causes no CO2 emissions when used as a fuel.
  • It is compatible with existing infrastructure and technologies for hydrogen production and utilisation.
  • It is cheaper and more efficient than steam reforming or electrolysis.
  • It is abundant and renewable.
• Its deposits have been found across the world, including in the US, Eastern Europe, Russia, Australia, France, and other countries.
• It is estimated that globally, there could be tens of billions of tonnes of white hydrogen.

Types of Hydrogen:

• Grey Hydrogen: It is produced via coal or lignite gasification(black or brown), or via a process called steam methane reformation (SMR) of natural gas or methane (grey). These tend to be mostly carbon-intensive processes.
• Blue Hydrogen: It is produced via natural gas or coal gasification combined with carbon capture storage (CCS) or carbon capture use (CCU) technologies to reduce carbon emissions.
• Green Hydrogen: It is produced using electrolysis of water with electricity generated by renewable energy.
