Nel ASA and Samsung E&A Debut Modular 100 MW Electrolyser, Shares Hit 52-Week High

Modular 100MW alkaline system cuts space by 50% and introduces single-performance-wrap guarantee, driving Nel stock to 52-week high amid EU hydrogen funding.

The green hydrogen industry's perennial struggle to finance large-scale projects may have found a new answer. On the floor of the World Hydrogen Summit in Rotterdam, Nel ASA and South Korea's Samsung E&A unveiled the CompassH2-A+, a modular 100-megawatt alkaline electrolysis system designed to collapse the barriers that have kept big industrial plants in the planning stage. Investors quickly rewarded the move: Nel stock touched a fresh 52-week high of €0.33 on Friday, closing up 13.37% and extending a rally that has lifted the shares by roughly 73% since the start of the year. In Oslo trading on Thursday, the first day of the summit, the stock had already gained 4.5% while the broader OBX index edged lower.

The platform, built around Nel's pressurised alkaline technology, strings together 25-MW containerised units into a 100-MW package that needs about 7,500 square metres of space — roughly 50% less than competing solutions. The system produces some 40 tonnes of green hydrogen daily at a purity of 99.999%, with an energy consumption of 48.8 kilowatt-hours per kilogram. A key engineering advantage is the output pressure of 15 barg, which reduces the need for downstream compression and lowers overall project capital expenditure.

The real innovation, however, lies in the financing structure. Samsung E&A is offering a single-performance-wrap guarantee that consolidates liability for electrolyser stacks, balance-of-plant equipment, and utility systems under one counterparty. Until now, fragmented warranty arrangements have often spooked banks and institutional investors, delaying or derailing final investment decisions. A long-term service contract covering operational support and scheduled stack replacements is bundled in, a move that Nel expects will accelerate project timelines significantly.

"Heading into heavy industry — steel, cement, chemicals — you need solutions that are scalable, bankable and competitive," said CEO Håkon Volldal. The partnership with Samsung addresses exactly that mix. Nel had already launched its own next-generation pressurised alkaline platform earlier in May, targeting a turnkey price below $1,450 per kilowatt for 25-MW systems.

The stock's surge is not an isolated event. European hydrogen names rallied broadly on Friday, with Ceres Power and ITM Power both posting double-digit gains (Ceres was helped by speculation of a tie?up with Doosan). Broader policy support is also gathering steam: the European Commission approved €1.3 billion in German state aid for green hydrogen, with tenders expected to begin in 2026. Gasunie, the Dutch infrastructure operator, has commissioned a 32-kilometre hydrogen pipeline in the port of Rotterdam.

Nel's first-quarter figures, released the same day as the platform launch, showed revenue slipping 5% to 148 million Norwegian kroner. The market largely shrugged off the decline, focusing instead on the technology roadmap. A separate bright spot came from Cavendish Hydrogen, Nel's spin?off, which lifted quarterly revenue by 47% to €2.8 million and secured a €4.8 million capital increase from BHDT GmbH.

On the project front, Nel's WAL initiative in Germany has already secured capacity in GASCADE's hydrogen core network, with plans to scale from 100 megawatts to 600 megawatts. That target aligns neatly with the modular design of the CompassH2-A+: add another 25-MW block, scale up, and keep the same guaranteed performance.

Green hydrogen remains a cost-intensive bet. But by packaging technology with a wrap guarantee that addresses the industry's biggest financing headache, Nel and Samsung have given heavy-industry buyers and their lenders a structure that might finally move the needle. The modular approach — and the political momentum behind Europe's hydrogen backbone — ensures the coming months will be a critical test of whether the platform can convert pipeline talk into steel?in?the?ground reality.
