(December 12, 2025 - Oslo, Norway) Nel ASA (Nel, OSE: NEL) is pleased to
announce that following a seven-year development program, and now a successful
start-up and production of clean hydrogen on the Next Generation Pressurized
Alkaline prototype, the Board of Directors has taken the final investment
decision to begin construction on up to 1 GW of production capacity for this
technology platform in the Herøya facility, Norway. The project is supported by
the EU Innovation Fund.

Development of the Next Generation Pressurized Alkaline system was initiated in
2018 and after rigorous testing of various smaller stacks, Nel has now completed
full-scale testing of the prototype at Herøya Industripark, Norway, validating
market-leading system efficiency. The company expects to launch the system
commercially in the first half of 2026 and be able to deliver at scale in 2027.

Building on 100 years of technology experience, Nel's Next Generation
Pressurized Alkaline platform delivers a breakthrough in clean hydrogen
economics, dramatically reducing system CAPEX and improving energy efficiency,
driving down levelized cost of hydrogen (LCOH). This leap is expected to improve
overall hydrogen production economics, and bridge critical funding gaps for
hydrogen installations.

"Our new solution is extremely important for Nel as a company, but also for the
clean hydrogen industry as a whole. A significantly improved levelized cost of
hydrogen is expected to unlock business cases that were previously not viable
without significant subsidies," says Håkon Volldal, President and CEO of Nel.

The platform is based on a fully modularized, skid-based design where every
module is pre-fabricated and factory-tested before shipment in standard
container skids. This approach dramatically simplifies engineering, logistics,
and installation and is expected to transform complex projects into streamlined
product deliveries. The system is designed to operate reliably outdoors, where
costs and deployment complexity are further reduced as no dedicated building
construction is required.

Nel has been granted up to EUR 135 million in support from the EU Innovation
Fund to industrialize the Next Generation Pressurized Alkaline platform,
enabling a total annual production output of 4 GW. This funding covers up to 60%
of relevant CAPEX and operational costs related to industrialization.

The initial 1 GW of production capacity is estimated at an investment of about
NOK 300 million before grants. The EU grant is milestone based and this
investment decision is expected to unlock in excess of EUR 10 million as a first
payment. The CAPEX is expected to be incurred throughout 2026 and 2027. Overall,
the CAPEX for this platform is significantly lower than for atmospheric alkaline
production lines.

Following the commercialization and industrialization of the pressurized
alkaline solution the company is looking into the book values of the two 500 MW
atmospheric alkaline production lines currently idling at Herøya.
