Hyliion Holdings Corp. (NYSE: HYLN) (“Hyliion”), a developer of sustainable electricity-producing technology, is proud to announce the successful commencement of manufacturing of additive parts for the KARNO generator at its headquarters in Austin, Texas. This significant achievement will assist with scaling capacity as the company moves towards delivering generators to customers later this year.

Between Hyliion’s headquarters in Austin, Texas, and its R&D facility in Milford, Ohio, the company currently owns over a dozen additive printing machines, with the intent to markedly grow its manufacturing capacity in the years ahead. The new additions to the manufacturing capabilities will include cutting-edge Colibrium Additive (formerly GE Additive) M Line printers that offer the latest in production speed and efficiency improvements.

Thomas Healy, Founder and CEO of Hyliion, commented, "Initiating additive production in Austin greatly enhances our manufacturing capacity as we gear up to deliver our first KARNO units to customers this year. By leveraging additive manufacturing, we can produce complex components while also scaling production economically for the KARNO generator."

The KARNO generator’s efficiency is significantly enhanced by the precision and innovation enabled through this advanced 3D printing process. Additive manufacturing allows for enhanced design flexibility, reduced material waste, and robust durability, setting a new standard for high-performance component production in the power generation industry.

The initial parts printed in Austin were aluminum cooling jackets used in the KARNO generator to remove the heat generated by the linear electric machine. In the coming months, the company will start producing additional additive components for the generator in Austin, scaling up production alongside its existing facility in Ohio.

The first KARNO generators are expected to be delivered to early adopter customers in the second half of 2024. These initial deployments will provide valuable real-world data and feedback, further refining the technology and solidifying Hyliion’s position as a pioneer in the power generation sector.
