First definition of what constitutes 'green ammonia' will allow it to become a tradeable commodity
All production processes will need to be powered by renewable energy — and use green hydrogen — with an upper limit of allowable greenhouse gas emissions
Hydrogen: hype, hope and the hard truths around its role in the energy transition
This means that every step of the production process — including the separation of nitrogen from the air, the production of hydrogen, and the synthesis of the two elements in the century-old Haber-Bosch process — must all be powered by renewable energy.
However, emissions from the construction of green ammonia production facilities and storage, conversion and delivery infrastructure will not count towards the total.
“The majority of early export-oriented green hydrogen projects plan to ship ammonia,” explained GH2 CEO Jonas Moberg.
“We are delighted that the Green Hydrogen Standard now defines green ammonia which is key to decarbonising our food and energy system,” Moberg adds. “This Standard is essential to establishing the global rules for the production, trade and use of sustainable zero-carbon fuels like green hydrogen and green ammonia.”
That definition was issued in May last year after a lengthy industry-wide consultation, giving some leeway for producers to use non-renewable electricity for back-up systems and for associated processes such as water treatment and desalination.
The scheme is entirely voluntary, but allows accredited projects to obtain and trade GH2 certificates of origin for green hydrogen and ammonia.
