Ohmium International Inc. (green hydrogen company) and Hynfra P.S.A. (renewable energy company) have signed a master cooperation agreement targeting large-scale green hydrogen and green ammonia development across three countries in the Middle East and Africa, the companies announced on June 17, 2026.

Scope of the Agreement

The partnership between Ohmium, a manufacturer of Proton Exchange Membrane electrolyzers headquartered in Newark, California, and Hynfra, a Warsaw-based green hydrogen and green ammonia project developer, covers the Front-End Engineering and Design stage for projects in Mauritania, Jordan, and Oman.

Under the terms of the agreement, Ohmium will also provide technical support and PEM electrolyzer expertise throughout the FEED and development stages for all three projects.

The cooperation agreement establishes a framework for ongoing collaboration between the two companies as the projects advance through development. Ohmium's role centers on contributing its modular PEM electrolyzer technology, which the company says enables rapid deployment and capacity flexibility at scale.

Green Ammonia as the End Product

All three projects are designed to produce green hydrogen for use in green ammonia applications. According to the announcement, the projects are intended to serve dual purposes: building domestically sourced clean energy capacity in the host countries to reduce dependence on imported fossil fuels, and producing RFNBO-compliant green ammonia for export, including to European markets.

RFNBO refers to Renewable Fuels of Non-Biological Origin, a classification used within European Union regulatory frameworks to certify the renewable credentials of hydrogen-derived fuels. The explicit targeting of RFNBO compliance signals that the projects are being structured from an early stage with European import requirements in mind.

Strategic Rationale for the Target Markets

The Middle East and Africa are described in the announcement as emerging hubs for green hydrogen development, with the companies citing the regions' abundant renewable resources and geographic proximity to global demand centers as key advantages.

For Mauritania, Jordan, and Oman specifically, developing domestic green hydrogen and green ammonia capacity is framed as a pathway to energy independence, economic diversification, and insulation from global energy price volatility.

Ohmium CEO Dr. Markus Tacke characterized the agreement as a significant step in the company's expansion into the Middle East and Africa. "Hynfra brings deep expertise and a bold vision for large-scale green hydrogen development, and together we will advance these projects to unlock green hydrogen and green ammonia production at scale," Tacke said in the announcement.

He added that the deal reflects what he described as growing global momentum for green hydrogen development.

Hynfra's Multi-Supplier Approach

Hynfra CEO Tomoho Umeda was direct in characterizing Ohmium's position within the company's broader technology strategy. Umeda said the company works with multiple technology partners across its green hydrogen and ammonia projects and deliberately maintains at least two qualified suppliers for each technology category.

"Ohmium is one of our PEM electrolyzer partners," Umeda stated, framing the arrangement as one component of a more complex, multi-partner development structure rather than an exclusive relationship.

Hynfra was founded by Umeda and draws on expertise rooted in Poland's conventional ammonia and fertilizer sector, including experience associated with Grupa Azoty, described as one of Europe's largest chemical groups. The company has a growing division in Hamburg, Germany, and maintains active project pipelines across Europe, the Middle East, Asia, and Africa.

Ohmium's Technology and Market Position

Ohmium designs and manufactures modular, scalable PEM electrolyzers, with the company describing its products as enabling cost-competitive green hydrogen production for industrial, transportation, and energy applications. The company is headquartered in the United States and operates manufacturing facilities in India, with operations described as worldwide.

Ohmium states that its global green hydrogen project pipeline exceeds 2 gigawatts across three continents. In 2023, the company raised $250 million in Series C financing, a round led by TPG Rise Climate.

The modular nature of Ohmium's electrolyzer technology is cited in the announcement as particularly suited to the demands of large-scale project development in regions where deployment speed and the ability to scale capacity incrementally are operationally important.

Industry Context

The agreement comes as green hydrogen continues to attract significant investment and policy attention, particularly in Europe where import frameworks for renewable fuels are becoming increasingly formalized.

The RFNBO compliance focus embedded in the Mauritania, Jordan, and Oman projects reflects a broader trend of developers structuring projects in Africa and the Middle East specifically to meet European certification standards, positioning those regions as upstream suppliers to anticipated European demand.

Hynfra's deliberate multi-supplier policy across technology categories also reflects a risk management philosophy common among large-scale project developers, who frequently maintain competitive tension among equipment vendors through parallel qualification processes, particularly at early development stages such as FEED.

Tracking the Middle East's Hydrogen Ambitions Before the Competition Does

The Middle East is moving fast on hydrogen, and the window to position your organization ahead of major procurement cycles is narrowing with every passing month. Are you confident you have full visibility into where the region's green and blue hydrogen projects are heading next?

The Global Project Tracking (GPT) platform by Blackridge Research gives hydrogen industry professionals a structured, continuously updated view of project activity across the Middle East, from early development pipelines through to completed infrastructure. Whether you are tracking export terminal developments, electrolyzer deployments, or ammonia conversion facilities, the platform surfaces the intelligence your team needs to act decisively.

Rather than piecing together fragmented news sources and delayed government announcements, the GPT platform consolidates hydrogen project data into a single, searchable environment built for strategic decision-making in fast-moving markets like the Middle East.
