GREEN14

GREEN14 produces premium spherical metal powders from circular feedstock such as out-of-spec powder and industrial scrap, using a hydrogen plasma reactor steered by its own AI control stack. Titanium Ti64 is presented as the validated material, with tungsten and silicon reduction described as in development. The company also offers its reactor as a license, with customers asked to share a powder spec and feedstock.

The website names aerospace and additive manufacturing as target uses for the powder, and defence and energy for tungsten. It describes a business model of powder supply plus reactor licensing, and lists partners including INGKA Group, GKN Aerospace, Oerlikon Metco, KTH, Tata Steel and the Swedish Energy Agency. The website does not state customer counts or revenue.

The site states that the team has backgrounds at NASA, KTH Royal Institute of Technology, Northvolt, Imperial College London, Elkem Technology and COMSOL, and that the pilot reactor operates at KTH in Stockholm. Four open positions are listed, all in Stockholm: three in simulation and one Junior Process Technician. The website does not give a founding year or funding details.
