Syzygy Plasmonics

Syzygy Plasmonics is a deep-decarbonization company that is electrifying chemical manufacturing.

Syzygy is commercializing a deep-decarbonization platform dedicated to cleaning up the emissions-heavy chemical industry. 

Syzygy was founded in 2017 at Rice University by Trevor Best, Suman Khatiwada, Naomi Halas and Peter Nordlander. The company is headquartered in Houston, Texas.


Syzygy technology combines two major recent breakthroughs, the first was the invention of high-performance photocatalysts. The second was the engineering of a novel reactor that uses common low-cost materials like glass, aluminum, and LEDs instead of high-cost metal alloys.


Syzygy's photoreactor reactor technology, dubbed Rigel, has the potential to help eliminate combustion from the chemical industry. This provides a clear path forward for combatting the greenhouse gas emissions produced during the manufacturing process for products we use every day.


Syzygy's technology is capable of performing multiple different chemical reactions and plan to enter the market with photocatalytic steam methane reforming to generate hydrogen gas.


Syzygy is backed by Horizons Ventures, The Engine, Carbon Direct Capital, Equinor Ventures, Aramco Ventures, Chevron Technology Ventures, Toyota Ventures, Pan American Energy, LOTTE CHEMICAL, GOOSE Capital, and others. The company raised $76M in Series C round on Nov 16, 2022. This brings Syzygy's total funding to $104.8M to date.
