Cypress, Calif., September 9, 2025 — Sapphire Technologies, a manufacturer of power generation equipment, has announced the close of its Series C financing round, raising $18 million.

The company's technology has been deployed in assets like high-pressure wells and natural gas pipelines since 2021, adding reliable and clean generation capacity to the global electric grid.

Freddie Sarhan, CEO of Sapphire Technologies, commented on the funding and the company's commitment to Japan: "Japan is one of the most important global markets for Sapphire. This partnership will accelerate the deployment of waste pressure power generation equipment across natural gas infrastructure, supporting the world's surging energy demand."

Ricky Sakai, Senior Vice President, Investment & Business Development, Mitsubishi Heavy Industries America, Inc., highlighted the potential of FreeSpin® in the energy transition: "Technologies such as FreeSpin® have the potential to play a meaningful role in the energy transition by converting existing pressure into electricity without additional fuel or direct emissions. Our investment supports the next phase of field deployments in key markets intending to add dependable capacity where demand is growing and lowering carbon intensity."

The funding will be used to increase capacity at Sapphire Technologies' new Cypress, California manufacturing facility, continue to grow the installed base of FreeSpin® In-line Turboexpanders in key geographies such as Japan, and expand market reach into new applications.
