China’s push to develop a hydrogen business appears to be extending from the domestic to the export market, signified by a landmark long-term green ammonia purchase agreement between China’s Envision and Japanese trading house Marubeni earlier this month.

This is still building up to scale but aims to produce some 1.5 million tons per year on full completion.
