Plug Power announced the signing of a memorandum of understanding (MoU) with Allied Green Ammonia (AGA) to supply up to 3 gigawatts (GW) of Plug electrolyzer capacity for AGA’s upcoming H₂ to ammonia facility proposed for the Northern Territory of Australia.

Following the MoU, Plug and AGA plan to enter an agreement, as outlined in the MoU, to initiate a basic engineering and design package (BEDP) for the 3-GW capacity project. The BEDP is expected to advance mid-May of this year, with final investment decision (FID) planned for Q4 2025 and the progressive delivery of the 3-GW electrolyzer supply slated to begin in Q1, 2027.

“Ammonia producers have recognized the substantial advantages of cost and carbon reduction through electrolysis-based H₂,” said Plug CEO Andy Marsh. “We’re thrilled to sign this MoU and partner with AGA. Our expertise in constructing and operating large-scale H₂ production facilities and our PEM electrolyzer manufacturing capability to support their 3-GW project position us as the ideal partner for this endeavor.”

Alfred Benedict, Founder & Managing Director of AGA said, “Our MoU with Plug builds on a long list of leading global firms who are joining us on our journey to build one of the largest green ammonia production facilities in the world, in a strategically located part of Australia given its proximity to Asia. This agreement, in light of Plug’s unrivalled expertise and complementary technologies, is a strong vote of confidence in our capabilities and a significant milestone in the planned delivery of Allied Green’s facility, which will be one of the most energy efficient green H₂ and green ammonia projects globally. Given our respective track records in delivering clean energy infrastructure, this agreement is a critical first step and a testament to the alignment of our respective visions to provide tangible solutions that enable the world to achieve net-zero.”

Green H₂ produced by Plug’s electrolyzers can help decarbonize the ammonia production process by displacing steam methane reforming (SMR) techniques. In addition to its environmental advantages, Plug's pressurized (40 bar) electrolyzer decreases downstream compression requirements and the extracted oxygen from electrolysis-based H₂ can enhance efficiency in industrial power plants and furnaces due to its high-temperature combustion capability.

AGA’s production facility will operate a 2,500 metric tpd green ammonia process. It taps into abundant renewable energy resources and strong energy infrastructure, the proposed location Gove Peninsula strategically aligning with Asia's trading partnerships. The facility is geographically positioned to meet AGA’s intended customers’ growing needs, providing them with a reliable and secure supply of green ammonia from the region.
