Shares of Plug Power Inc. (PLUG), a supplier of hydrogen fuel cells and electrolyzers, climbed close to 5% in premarket trading on Tuesday after the company announced a supply agreement tied to Europe's growing clean aviation fuel market.

Under the deal, Plug will supply 280 megawatts of electrolyzers to Arcadia eFuels for Project ENDOR, a planned production facility in Denmark. The plant will be sited at the Port of Vordingborg on Denmark's south coast and will run Plug's GenEco electrolyzers on renewable grid power. The GenEco line uses proton-exchange membrane technology, which can ramp production up and down to track variable renewable output. Once operational, it is expected to produce around 110 tons of renewable hydrogen every day.

That hydrogen is the starting point for the fuel Arcadia intends to make. The company plans to combine it with captured carbon dioxide to produce e-SAF, a synthetic jet fuel that works in standard aircraft without any engine modifications. That drop-in compatibility is significant for aviation, a sector where long-haul routes have no near-term battery alternative and remain dependent on liquid fuel. It also sets e-SAF apart from most sustainable aviation fuel produced today, which is refined from feedstocks such as used cooking oil and waste fats; because e-SAF is built from hydrogen and captured carbon, its production is not tied to the availability of those feedstocks.

A Larger Pipeline Behind the Deal

The ENDOR agreement is only one part of a broader arrangement. Plug and Arcadia also signed a strategic cooperation agreement covering four additional projects, which together represent more than 1 gigawatt of potential electrolyzer capacity spread across Europe and the Americas. The cooperation agreement makes Plug the preferred supplier for that future pipeline.

As part of the framework, Arcadia receives priority access to Plug's manufacturing capacity, a provision that becomes relevant as each of the additional projects moves forward. The agreement is the product of roughly three years of joint engineering work between the two companies. Plug described the supply deal as one of several project documents Arcadia needs before making a final decision on ENDOR.

What Still Needs to Happen

While the agreements are signed, the timeline remains open. Equipment deliveries have not started, and shipments for the 280 MW ENDOR project will begin only after Arcadia issues a formal notice to proceed. Project ENDOR has also not yet reached a final investment decision, the milestone that typically determines whether a project actually gets built and financed.

The four additional projects covered by the cooperation agreement represent potential business rather than confirmed orders. Financing and construction decisions on those projects remain the milestones to watch.

Regulatory Push Behind e-SAF

Demand for e-SAF is being driven largely by regulation. The European Union's ReFuelEU Aviation rules, part of the EU's broader Fit for 55 climate package, require a growing share of sustainable fuel at European airports, starting at 2% in 2025 and rising over time, and include a specific carve-out for synthetic aviation fuels beginning at 1.2% in 2030 and climbing to 35% by 2050. The obligation applies to fuel supplied at EU airports regardless of where that fuel is produced. That mandate is the segment Arcadia and Plug are targeting with the Danish project.

Plug already has an established presence in the European hydrogen market. The company is working on multiple hydrogen projects across Denmark, the United Kingdom, Spain, and Portugal. One example is a 100 MW GenEco installation at Galp's Sines refinery in Portugal, which is already underway as Plug builds out its European electrolyzer business.

The Arcadia agreement adds another potential customer to that roster, contingent on financing and construction milestones still to come. Plug Power stock was trading up close to 5% in premarket action following the announcement.
