The Colours of Hydrogen - White Hydrogen

The Colours of Hydrogen

Discover how White Hydrogen leads the way in sustainable, carbon-negative energy production.

The Hydrogen Colour Spectrum

The hydrogen industry uses colours to categorize production methods based on their environmental impact and energy sources. White Hydrogen, produced with H2-XERONOX® technology, stands out for its carbon-negative potential and use of waste feedstocks.

Why Colours Matter

Sustainability in Hydrogen Production

Most hydrogen today is produced from fossil fuels, contributing to significant CO₂ emissions. The colour of hydrogen indicates its environmental footprint, helping industries choose cleaner options for a net-zero future.

White Hydrogen offers a sustainable alternative by converting waste into clean energy with minimal emissions.

Hydrogen Types Explained

White Hydrogen

Produced with H2-XERONOX® converts biodiesel glycerol waste thermochemically, enabling a scalable, carbon-negative solution for decentralised, local energy and clean hydrogen production.

🌱
Green Hydrogen

Generated through electrolysis powered by renewable energy (solar or wind). Clean but costly, requiring significant water and land resources.

Black/Brown Hydrogen

Derived from coal gasification (black = bituminous, brown = lignite). Highly polluting with substantial CO₂ emissions.

🌫️
Grey Hydrogen

Produced from natural gas via steam methane reforming (SMR) without carbon capture. Common but emits significant CO₂.

🔵
Blue Hydrogen

Similar to grey hydrogen but uses carbon capture and storage (CCS). Reduces emissions but still produces 10–20% CO₂ and requires CCS infrastructure.

🟦
Turquoise Hydrogen

Created through methane pyrolysis, producing solid carbon as a byproduct. Emerging technology with limited commercial application.

🎀
Pink/Purple Hydrogen

Generated via electrolysis powered by nuclear energy. Low-carbon but dependent on nuclear infrastructure.

🟨
Yellow Hydrogen

Produced via electrolysis using a mixed energy grid, often including fossil fuels. Less sustainable due to variable carbon footprint.

The Future of White Hydrogen

White Hydrogen, powered by H2-XERONOX®, offers a scalable, carbon-negative solution for decarbonizing industries.

Waste-to-Energy

Converts agricultural and plastic waste into clean hydrogen.

Carbon-Negative

Reduces emissions by avoiding landfill waste.

No CCS Required

Eliminates the need for costly carbon storage systems.

Scalable Design

Modular systems deployable in 20ft containers.
