Geneva-based non-profit the Green Hydrogen Organisation (GH2) has updated its green hydrogen standard, published in May last year, with a protocol for defining green ammonia.

To qualify for certification, ammonia must be manufactured by green hydrogen produced per GH2’s standard with solely—or “near 100pc”—renewable energy and close to zero greenhouse gas emissions, with an average emissions intensity of 0.3kg CO₂e per kg of ammonia over a 12-month period.

GH2’s standard was set up to bridge the gap between countries and regions setting up their own regulations. Producers can opt in to obtain and trade GH2 certificates of origin for green hydrogen and its derivatives, including ammonia.

“The standard provides certainty and transparency to investors and other stakeholders that green hydrogen is exactly that: hydrogen made with renewable electricity which conforms to the highest standards on emissions, ESG and the sustainable development goals,” says GH2 chair and former Australian prime minister Malcolm Turnbull.

Six green hydrogen projects—developed by Australia’s Fortescue Future Industries, China’s Envision, and US-based Hy Stor Energy—are being assessed for compliance with GH2’s standard by risk management company DNV.
