What is green hydrogen? An expert explains its benefits | World ...
网页2021年12月21日 · Green hydrogen is defined as hydrogen produced by splitting water into hydrogen and oxygen using renewable electricity. This is a very different pathway compared to both grey and blue. Grey hydrogen is traditionally produced from methane (CH4), split with steam into CO2 – the main culprit for climate change – and H2, hydrogen.
Hydrogen is a key fuel for our sustainable future
网页2023年12月7日 · Hydrogen, the simplest and most abundant element in the universe, has the potential to be the fuel of the future. It's an energy carrier that can store and deliver energy in a usable form. In its pure form, hydrogen is a colourless, odourless and non-toxic gas. It's high in energy, yet an engine that burns pure hydrogen produces almost no ...

Grey, blue, green – why are there so many colours of hydrogen?
网页2021年7月27日 · Black, brown and grey hydrogen. Grey hydrogen is the most common form and is generated from natural gas, or methane, through a process called “steam reforming”. This process generates just a smaller amount of emissions than black or brown hydrogen, which uses black (bituminous) or brown (lignite) coal in the hydrogen-making process.
Hydrogen is developing fast in Japan, closer to societal use
网页2024年4月10日 · In June 2023, the Japanese government revised its Basic Hydrogen Strategy to support such corporate initiatives. This strategy identifies nine key technologies, including fuel cells and water electrolysis devices and has decided to invest over JPY 15 trillion ($98.8 billion) over the next 15 years. It also aims to increase hydrogen usage to 12 ...
