Founded in 2018 to commercialize a radical new technology developed at Houston's Rice University, Syzygy builds reactors that use light instead of combustion to electrify chemical manufacturing and power a cleaner, safer world. When powered with renewable electricity, this tunable technology is designed to reduce both cost and emissions associated with many different chemical reactions.

Syzygy's solutions enable manufacturers to produce zero-emissions hydrogen from ammonia and low-emissions hydrogen from a combustion-free form of steam methane reforming. They also provide efficient means for converting methane and captured CO2 into sustainable fuels and methanol.

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. 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.
