The Green Hydrogen Standard (GH2) defines green ammonia and establishes global rules for its production, trade, and use. The standard includes the following requirements:
Greenhouse gas emissions
Green ammonia must have greenhouse gas emissions of less than or equal to 0.3 kg CO2e per kg NH3 over a 12-month period.
Renewable energy
The entire production process, including hydrogen production and the synthesis of ammonia, must be powered by renewable energy.
Beneficial ownership transparency
Project operators must disclose legal and beneficial ownership, including the identity of the beneficial owner(s), the level of ownership, and how ownership or control is exerted.
The GH2 Standard also includes requirements for project overview, stakeholder engagement, project location and design, and social impact.
Green ammonia is produced using green hydrogen, which is hydrogen produced through the electrolysis of water using renewable energy. Green ammonia has several advantages, including:
Low emissions
Green ammonia combustion produces only nitrogen and water as byproducts, eliminating the release of harmful pollutants.
High energy density
Green ammonia has a high energy density, making it suitable for powering large vessels.
Easy to transport
Green ammonia is relatively easy to transport compared to compressed or liquid hydrogen.
