Electrochemical hydrogen production: sustainable hydrogen …

2. Electrochemical production of hydrogen. As the most prevalent element in the universe, hydrogen is easily accessible in the form of biomass from plants, water, hydrocarbons, and other organic substances. Hydrogen is currently produced more for use as a chemical or reducing agent than as a fuel.

What is green hydrogen and why do we need it? An expert explains

Grey hydrogen is traditionally produced from methane (CH4), split with steam into CO2 – the main culprit for climate change – and H2, hydrogen. Grey hydrogen has increasingly been produced also from coal, with significantly higher CO2 emissions per unit of hydrogen produced, so much that is often called brown or black hydrogen …

Executive summary – Global Hydrogen Review 2022 – Analysis

Much of the increase in hydrogen demand in 2021 was met by hydrogen produced from unabated fossil fuels, meaning there was no benefit for mitigating climate change. The production of low-emission hydrogen was less than 1 Mt in 2021, practically all of it coming from plants using fossil fuels with carbon capture, utilisation and storage (CCUS).
