A Houston-based company that's created a photocatalytic reactor that uses light instead of heat to cleanly manufacture chemicals has announced its latest investor.

Syzygy Plasmonics announced a strategic investment agreement with Mitsubishi Heavy Industries Ltd., executed through Mitsubishi Heavy Industries America Inc. The terms of the deal were not disclosed, but Syzygy reports that the funding will go toward commercialization and development of its products.

"MHIA has been making moves to establish themselves as one of the leaders in the energy transition," Syzygy CEO Trevor Best says in a news release. "Formalizing our relationship with them shows their commitment to helping scale cutting edge technology and opens up new avenues for Syzygy and MHIA to work together as we commercialize our industrial decarbonization platform."

Currently, Rigel, the commercial-scale photoreactor, is being tested in Syzygy's Pearland facility. Founded based off a breakthrough discovery out of Rice University from co-founders and professors Naomi Halas and Peter Nordlander, Syzygy closed a $76 million series C financing round last year, a $23 million series B round in 2021, and its $5.8 series A in 2019.

The funding will support advancement and commercialization of the technology and is a part of Mitsubishi Heavy Industries Group's commitment to decarbonization.

"By collaborating with and investing in partners with innovative technologies, MHI Group is working to build a hydrogen ecosystem and a CO₂ ecosystem that can contribute to the realization of a decarbonized society," the company writes in a statement. "Through this investment, Mitsubishi Heavy Industries will support Syzygy's efforts to develop innovative alternative technologies that will lead to the diversification of both ecosystems."
