US company Plug Power has agreed to supply 3GW of electrolyser capacity to Australia's Allied Green Ammonia (AGA) for their hydrogen-to-ammonia plant in the Northern Territory. This 'mega project' will utilize a 4.5GW solar plant for power and aims to produce 2,700 metric tonnes per day of green ammonia to meet the demand from European and Asian markets. The partnership highlights the importance of strong alliances for successful ventures in green energy. Plug Power's electrolysers, based on Proton Exchange Membrane (PEM) stack technology, offer adjustable output based on electrical input, complementing renewable energy sources effectively. The Final Investment Decision for this project is expected by Q2 2025, with deliveries commencing in Q1 2027. CEO Andy Marsh sees a growing interest among ammonia producers in electrolyser-produced hydrogen for cost and emission reductions. The Australian government's support for the green hydrogen sector, through the Future Made in Australia strategy, includes a significant allocation to promote local green hydrogen production. Market analysis suggests that ammonia production, particularly using green hydrogen, will play a pivotal role in the growth of the sector. Ammonia, a key compound in fertilizers and industrial chemicals, shows promising market growth potential, with an estimated increase from 191.97 million tonnes in 2025 to 210.81 million tonnes by 2030.
