Nel Pressurized Alkaline PA-Series Electrolyser

Nel ASA is an Oslo Stock Exchange-listed hydrogen technology company whose site traces its history to 1927, when a small electrolyser was installed at Norsk Hydro in Notodden, Norway. It supplies alkaline and PEM electrolysers and reports 7,000+ stacks delivered in 80+ countries.

On 6 May 2026 Nel launched a next-generation pressurized alkaline platform. It is a modular, skid-based, factory-tested design operating at 15 bar, intended for outdoor installation with minimal civil works, with production capacity of up to 1 GW per year at Herøya, Norway.

• Modular skids: factory-assembled and tested units sold as standardized products.
• Pressurized operation: 15 bar configuration reduces downstream compression.
• Outdoor design: minimal civil works at site.
• Hydrogen quality: 99.99% purity at 30 bar delivered hydrogen in the cost basis.
• Industrial scale-up: up to 1 GW per year at Herøya with a roadmap to 4 GW.

Utility-scale green hydrogen or ammonia plants in southern Vietnam. Steel and chemicals plants replacing fossil hydrogen. Export-oriented hydrogen projects in Southeast Asia.

Company estimates a turnkey full-scope cost below USD 1,450/kW for a 25 MW plant. Nel states system CAPEX is 40-60% lower than current market offerings. Factory-assembled skids aim to shorten project timelines and lower execution risk. These figures are company claims, not independently verified.

Buyers of green hydrogen projects are pressing electrolyzer vendors for lower installed cost and standardized products. Vietnam and Southeast Asia are developing hydrogen strategies, which may create demand for standardized large-scale systems.
