The colours correspond to the GHG emission profile of the energy source or process used to extract hydrogen. The brighter colours (e.g. green, blue, even turquoise and pink!) have lower emissions, while the gloomier colours (grey, brown and black) have higher emissions and a gloomier outlook for global warming.
From green to pink hydrogen, we reveal the rainbow of hydrogen colours and the different types of technology used to produce each. Here''s our guide to unlocking the current hydrogen colour code.
So, what exactly is the meaning behind each color of hydrogen? Today, we''ll talk about the twelve colors of hydrogen, including their production methods, use cases, and our predictions for the future of hydrogen energy. Table of Contents. Traditional Hydrogen Production Methods: Gray hydrogen; Black hydrogen; Brown hydrogen
Hydrogen has many colours, and we frequently refer to green, turquoise, blue and grey hydrogen. Since this versatile energy carrier is actually a colourless gas, one might well ask what these colours actually mean.
Only a tiny percentage of hydrogen produced today is green; in fact, all low-carbon types of hydrogen (that includes blue, pink, yellow, turquoise, and aqua) account for less than 1% of global
5 · Depending on production methods, hydrogen can be grey, blue or green – and sometimes even pink, yellow or turquoise – although naming conventions can vary across countries and over time.
The colour discussion is currently dominated by grey, blue and green hydrogen, though there are eight colours formally acknowledged, including pink and turquoise. Hydrogen has emerged as the energy technology that could help nations like Australia to decarbonise their economies.
This video explains what each "color" of hydrogen refers to and why it makes a difference in terms of how good it is as a substitute for climate-warming fossil fuels. Black or brown hydrogen comes from coal, which is a fossil fuel. The first step to get that H 2 is gasification (see video below).
When talking about hydrogen as a fuel, it is assigned different colors, such as green, blue, and gray based on how clean it is. Yes, hydrogen is a colorless gas. We may use blue or green when visualizing hydrogen molecules, but that''s for the sake of aesthetics more than anything.
Hydrogen itself is a colourless gas but there are around nine colour codes to identify hydrogen. The colours codes of hydrogen refer to the source or the process used to make hydrogen. These codes are: green, blue, grey, brown
