- NOS Nova AS is a Norwegian technology and engineering company that provides carbon capture and storage infrastructure solutions, proprietary carbon management technologies, and specialized engineering services. The company offers multidisciplinary engineering and technological consulting services, including mechanical design, fabrication support, and specialized equipment manufacturing for aerospace and offshore energy applications; midstream carbon dioxide transport and terminal infrastructure solutions; proprietary carbontech intellectual property and patented system designs for carbon storage; and technical, environmental, and commercial advisory studies for industrial emitters, terminal operators, and storage developers. Headquartered in Sandnes, Norway, the company was founded in 2019 and operates primarily through subsidiaries including NOS Technology AS, which delivers high-precision engineering services to the aerospace, industrial, and energy sectors, and NOS CarbonGrid AS, which oversees midstream carbon infrastructure development and commercialization studies for European and Norwegian markets. In recent developments, the company underwent a major strategic restructuring following NOS Group acquiring a majority ownership stake in August 2025. In November 2025, the company acquired NOS Technology AS for NOK 27.5 million to integrate dedicated engineering capabilities and expand commercial contracts, including aerospace tooling and equipment projects. In December 2025, the company changed its corporate name from Horisont Energi AS to NOS Nova AS, trading under the ticker symbol NOSN on Euronext Growth Oslo. As part of its operational realignment toward high-margin engineering services and intellectual property monetization, the company spun off its Barents Blue clean ammonia asset and expanded its international patent portfolio covering large-scale carbon dioxide transport and injection technologies.
