CYPRESS, Calif., Sept. 09, 2025 (GLOBE NEWSWIRE) -- Sapphire Technologies, manufacturer of power generation equipment, today announced the close of its Series C financing, including investment from Mitsubishi Heavy Industries, Ltd. (MHI) and alongside existing investors Equinor Ventures, Cooper and Company, and Energy Capital Ventures®. The capital 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.
Turboexpanders convert the energy wasted by pressure reduction processes into clean electric power. Assets in the energy sector often contain ready-to-develop pressure resources, like natural gas wells that must be choked prior to processing and transmission pipelines that must be let down before interconnecting with local distribution pipelines. Turboexpanders can be introduced into these processes to generate carbon-free electricity.
“Japan is one of the most important global markets for Sapphire,” said Freddie Sarhan, CEO of Sapphire Technologies. “We are deepening our commitment to our Japanese clients. This partnership will accelerate the deployment of waste pressure power generation equipment across natural gas infrastructure, supporting the world’s surging energy demand.”
“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,” said Ricky Sakai, Senior Vice President, Investment & Business Development, Mitsubishi Heavy Industries America, Inc. “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.”
