GSP was joined for the announcement in Seoul as part of an International Leadership Mission where more 60 delegates from Greater Seattle are strengthening and advancing the region’s ties with South Korea in both the public and private sectors including aerospace, bio/life sciences, clean tech, education, maritime, and technology such as quantum computing, data, and artificial intelligence. 

GSP first engaged CTNS in 2023 as part of SelectUSA program and has since extensively toured the region across King, Pierce and Snohomish County engaging with the Clean Energy Test Beds at the University of Washington, K-Startup Center, Pacific Northwest Aerospace Alliance (PNAA), Washington Maritime Blue, and the Washington State Department of Commerce. CTNS will also participate in the Greater Seattle Export Accelerator Cohort 2 program. 

With the recently signed contract to supply EV battery pack production facilities and initial production volume worth more than $10 million with Aptera Motors, a ‘first-of-its-kind’ solar electric vehicle maker, CTNS aims not only to successfully complete the first phase of the project, but also to sign a mass production contract by 2025. Upon achieving this goal, orders are expected to reach $100 million annually. 

CTNS will initially be located in the K-Startup Center in downtown Seattle. Development plans include growing its North American HQ in the Greater Seattle region and opening a manufacturing center.
