How did Nel ASA's origins at Norsk Hydro shape its journey to a hydrogen pioneer?
Nel ASA began as Norsk Hydro's internal hydrogen unit and scaled into a global pure-play on hydrogen. Its history matters because it shows deliberate industrial scaling amid volatile 2025 results and rising 2026 commercial launches.
Nel ASA's shift from captive utility to GW-scale manufacturer drove focus on cutting LCOH; losses in 2025 contrast with a May 2026 pressurized alkaline product launch. See NEL SWOT Analysis for product context.
How Did NEL Get Started?
Nel ASA started in 1927 in Notodden, Norway, as an electrolysis unit inside Norsk Hydro to supply hydrogen for ammonia production, leveraging abundant hydroelectric power to avoid coal gasification. The pragmatic need for large-scale hydrogen shaped an engineering-centred firm focused on alkaline water electrolysis.
Nel ASA: origins as an electrolysis unit for Norsk Hydro
Norsk Hydro established a dedicated electrolysis unit in 1927 to produce hydrogen for ammonia fertilizer, using cheap Norwegian hydroelectricity. Early focus on alkaline electrolysers set the technical base that later enabled Nel ASA hydrogen leadership.
- Founding period: 1927
- Founders: Norsk Hydro engineering team in Notodden, Norway
- Original idea/need: scalable hydrogen supply for ammonia/fertilizer production via water electrolysis
- What shaped the launch: abundant hydroelectric power and avoidance of coal gasification
Key early milestone: construction in 1940 of the Rjukan plant, then the world's largest water electrolysis facility, producing over 30,000 Nm3/hour, which entrenched Nel electrolyser company expertise decades before modern green hydrogen markets emerged.
Between 1927 and the 2000s, the organization evolved from an internal Norsk Hydro unit into an independent industrial entity focused on alkaline electrolysis technology, laying groundwork for later NEL company milestones in commercial electrolysers, global project deployments, and strategic partnerships.
Technical legacy drove later business growth strategy: IP and operational experience from the Rjukan installation enabled product commercialization, scaling to industrial electrolyser manufacturing and exports throughout Europe by late 20th century.
Financial and corporate turning points included IPO-era moves and restructuring that positioned Nel for rapid expansion into PEM (proton exchange membrane) and alkaline markets; see a concise company profile at Who Owns NEL Company.
Relevant metrics and context for 2025: Nel ASA hydrogen product backlog and order pipeline reflected multi – GW project opportunities worldwide, and the firm reported multi – year revenue growth driven by large electrolyser contracts and government-supported hydrogen tenders across Europe and North America (refer to audited 2025 filings for exact figures).

How Did NEL Become What It Is Today?
Nel ASA became a global hydrogen-electrolyser leader by shifting from a Norsk Hydro division to an independent vendor in 2011, listing via a 2014 reverse takeover, then scaling technology and manufacturing through targeted acquisitions and gigafactory expansion.
Privatization and Market Entry
In 2011 private investors acquired the Norsk Hydro hydrogen unit and rebranded it as Nel Hydrogen, marking the start of independent commercialization. The firm accessed public capital by reverse-taking over Diagenic ASA in 2014 to list on the Oslo Stock Exchange, enabling rapid fundraising for growth.
Product and Technology Expansion
Nel expanded beyond alkaline electrolysers by acquiring Proton OnSite in 2017, adding Proton Exchange Membrane (PEM) technology to its portfolio. This dual-track approach positioned Nel ASA hydrogen offerings to serve both low-cost alkaline and high-purity PEM markets worldwide.
Industrial Scale and Global Reach
To close the scale gap Nel adopted a Gigafactory model, doubling Herøya capacity to 1 GW and scaling Wallingford to 500 MW, enabling supply of containerized electrolyzers and large industrial stacks across about 80 countries by 2024. Revenue and orderbook growth accelerated as utility, industrial, and transport contracts multiplied.
Defining Strategic Moves
The defining evolution combined capital-market access, the 2017 Proton OnSite acquisition, and factory industrialization-turning NEL electrolyser company know-how into mass-manufacturing capability. Strategic partnerships and government-supported projects amplified adoption and shortened time-to-contract.

The Moments That Changed NEL Everything?
Several decisive pivots reshaped NEL company history: the 2011 spin-out from Norsk Hydro, the 2017 Proton OnSite acquisition, the June 2024 fueling spin – off to Cavendish Hydrogen, Samsung E&A becoming largest shareholder in March 2025, and the December 12, 2025 FID to industrialize 1 GW Next – Gen Pressurized Alkaline at Herøya with EU Innovation Fund support.
| Year | Turning Point | Why It Mattered |
| 2011 | Spin – out from Norsk Hydro | Granted autonomy to sell electrolyser technology externally and pursue commercial contracts beyond internal projects. |
| 2017 | Acquisition of Proton OnSite | Secured PEM (proton exchange membrane) capabilities, preventing sidelining as PEM demand rose and broadening product mix. |
| June 2024 | Fueling division spun off to Cavendish Hydrogen | Refocused capital and management on core NEL electrolyser R&D and manufacturing; converted NEL into a pure – play electrolyser company. |
| Mar 2025 | Samsung E&A largest shareholder | Provided strategic industrial backing, supply – chain and project execution leverage for scale – up and EPC partnerships. |
| Dec 12, 2025 | FID for 1 GW Next – Gen Pressurized Alkaline at Herøya | Industrialization commitment supported by EU Innovation Fund; underpins 1 GW capacity build and moves NEL to volume manufacture. |
Key innovations, pivots, crises, and strategic decisions that changed path include technology diversification (alkaline and PEM), de – risking via acquisitions, structural refocus by spinning off downstream fueling, and securing industrial and public capital to scale manufacturing.
Next – Generation Pressurized Alkaline Scale – Up
The Dec 12, 2025 FID greenlit industrial production of the Next – Gen Pressurized Alkaline platform with 1 GW planned at Herøya, reducing unit costs and enabling competitive large – scale electrolyser supply.
