Ohmium and Hynfra sign master cooperation agreement for green hydrogen in MENA - news and statistics. Jun 22, 2026 Ohmium International Inc. and Hynfra P.S.A. have signed a master cooperation agreement to advance green hydrogen projects in Mauritania, Jordan, and Oman, as announced in a joint statement. The source of this information is a business wire release published on June 22, 2026. Scope of the agreement. The cooperation agreement covers the Front-End Engineering and Design (FEED) stage for the three projects and establishes a framework for ongoing collaboration. Ohmium will provide technical support and expertise related to its modular Proton Exchange Membrane (PEM) electrolyzers during the FEED and development stages. The projects are designed to produce green hydrogen for green ammonia applications, aiming to enhance energy security and long-term resilience in the host countries by building domestically sourced clean energy capacity and reducing reliance on imported fossil fuels. The output is also intended to supply RFNBO-compliant green ammonia for export, including to European markets. Executive perspectives. Dr. Markus Tacke, CEO of Ohmium International, described the agreement as an exciting milestone as the company expands into the Middle East and Africa. He noted that Hynfra brings deep expertise and a bold vision for large-scale green hydrogen development, and that the partnership will advance these projects to unlock production at scale. He added that the agreement reflects growing global momentum for green hydrogen development and Ohmium's commitment to playing a pivotal role in that growth. Tomoho Umeda, CEO of Hynfra, stated that the company works with multiple technology partners across its green hydrogen and ammonia projects and maintains at least two qualified suppliers for each technology category. He characterized this as a deliberate choice reflecting the complexity of what is being built, and confirmed that Ohmium is one of Hynfra's PEM electrolyzer partners. Strategic context. The Middle East and Africa are emerging as key hubs for green hydrogen, benefiting from abundant renewable resources and proximity to global demand centers. For Mauritania, Jordan, and Oman, developing domestic green hydrogen and green ammonia capacity offers a pathway to energy independence, economic diversification, and greater resilience to global energy price volatility. Ohmium's modular PEM electrolyzer technology is noted for enabling rapid deployment and capacity flexibility. The cooperation agreement between Hynfra and Ohmium reflects accelerating global momentum behind green hydrogen as a cornerstone of the energy transition and a critical tool for national energy security. By combining Ohmium's advanced PEM electrolyzer technology with Hynfra's project development expertise and regional relationships, the companies are positioned to deliver large-scale green hydrogen and green ammonia solutions that strengthen energy independence across the MENA region.
Ohmium and Hynfra target MENA green hydrogen growth with new ammonia projects in mauritania, jordan, and oman. A new cooperation agreement between Ohmium International and Hynfra aims to advance green hydrogen and green ammonia projects across Mauritania, Jordan, and Oman, targeting both domestic energy resilience and international fuel markets. The agreement covers the Front End Engineering and Design (FEED) phase of three projects and establishes a framework for collaboration throughout development. Ohmium will provide technical expertise related to its proton exchange membrane (PEM) electrolyzer technology, while Hynfra will contribute project development capabilities and regional experience. The partnership reflects a broader industry trend toward integrating electrolyzer suppliers with developers earlier in project lifecycles. As hydrogen projects move from conceptual stages toward commercial deployment, FEED studies have become increasingly important for assessing technical feasibility, infrastructure requirements, renewable energy integration, and cost competitiveness. Green ammonia is expected to be a primary application for the projects. Converting hydrogen into ammonia provides advantages for storage and transportation because ammonia can be handled using existing industrial infrastructure and has established global trade routes. It is also being considered as a potential low carbon fuel for sectors such as shipping, fertilizer production, and heavy industry. The three target countries illustrate the growing role of the Middle East and Africa in the emerging hydrogen economy. Mauritania has attracted attention due to its combination of large land availability, strong solar and wind resources, and proximity to European markets. Jordan is exploring hydrogen development as part of efforts to strengthen energy security in a country that relies heavily on imported energy. Oman is positioning itself as a regional hydrogen hub by leveraging renewable resources and existing industrial and port infrastructure. However, the competitiveness of these projects will depend on more than renewable energy availability. Large scale green hydrogen production requires significant investments in electricity generation, water supply, electrolyzers, storage, transportation infrastructure, and export facilities. The cost of renewable electricity remains one of the most important factors determining whether green hydrogen can compete with conventional hydrogen produced from natural gas. Ohmium's PEM electrolyzer technology is designed for flexible operation, allowing systems to respond more effectively to variable renewable power generation. PEM electrolyzers can adjust output rapidly, making them suitable for projects connected to intermittent solar and wind resources. However, long term commercial viability will depend on achieving high utilization rates and reducing capital costs across the hydrogen production chain. The companies also intend to target European markets through renewable fuel exports. Green ammonia produced under the projects is expected to align with the European Union's Renewable Fuels of Non Biological Origin (RFNBO) requirements, which establish criteria for renewable hydrogen and hydrogen derived fuels entering European markets. Demand for compliant renewable fuels is expected to increase as European industries face tighter emissions requirements. Shipping is one potential demand sector, with international regulations encouraging operators to reduce carbon intensity and explore alternatives to conventional marine fuels. The partnership also highlights a shift in hydrogen project development strategies, where developers are increasingly avoiding reliance on single technology providers. Hynfra stated that it works with multiple qualified suppliers across technology categories, reflecting the complexity and scale of hydrogen and ammonia infrastructure projects.
