Swiss engineering firm Casale announced on September 24, 2026 that it has signed a contract with Norwegian green ammonia developer Neptun Glomfjord Green Ammonia AS (NGGA) to supply a 100-tonnes-per-day modular green ammonia plant in Glomfjord, Norway.
Casale is a Swiss-headquartered ammonia and fertilizer process technology licensor, long regarded as a traditional leader in the industry, having supplied its process technology to large-scale ammonia and urea plants worldwide. The contract applies Casale’s proprietary SMART-N™ process technology and will be delivered under an EPF (Engineering-Procurement-Fabrication) model, according to the report. The SMART-N™ technology involves fabricating the plant in modular skid units at a factory before assembling them on-site, a method reported to significantly reduce the footprint compared with conventional large-scale ammonia plants while allowing flexible operation across 10-100% of nominal capacity. The client, Neptun Glomfjord Green Ammonia AS, is reported to be a developer pursuing renewable-based green ammonia production locally in Norway.
The plant being supplied has a production capacity of 100 tonnes per day (tpd) of green ammonia, and the specific contract value has not been disclosed.
The contract is understood as an example of small-scale, distributed modular green ammonia production facilities establishing themselves as a new alternative in a market that had previously been centered on large-scale ammonia plants.
Modular green ammonia plants are seen as well-suited to distributed locations near renewable power generation sites or demand centers, given their lower upfront investment burden and shorter construction timelines compared with large-scale plants. A design like this one, capable of flexible operation across 10-100% of nominal capacity, is cited as a technological trend addressing the common challenge faced by renewable-linked chemical plants of having to flexibly adjust electrolysis-based green hydrogen and green ammonia output in line with variable renewable power generation. Traditional ammonia and fertilizer process technology licensors such as Casale actively entering the modular small-plant market suggests that the green ammonia market is broadening from being centered on large projects to encompassing projects of various scales. It is also notable that such small-scale green ammonia facilities are being pursued in succession in a country like Norway, which has a high share of renewable power generation. The EPF approach, in which modules are pre-fabricated at a factory and then assembled on-site, is seen as an alternative that lowers construction risk and shortens schedules, making it possible to build large chemical facilities even in regions with relatively limited labor or infrastructure. It is also anticipated that a growing number of small-scale green ammonia facilities could enable tailored production suited to a range of end uses, such as fertilizer and marine fuel, going forward.
When this plant will break ground and its actual completion and startup schedule are of interest. How the end demand and sales contracts for the green ammonia produced will be structured is also a matter of interest. Whether Casale’s SMART-N™ technology will lead to additional orders in other regions following this project is also worth watching. How Norway’s government support policies for renewable energy and green ammonia could affect this project’s economics is also of interest.
