Clean energy startup to expand to Houston with $40M facility

coming soon to Hou

Brooklyn, New York-based clean energy startup Amogy, which specializes in turning ammonia into power, is spending more than $40 million to convert a Houston building into a manufacturing facility.

Amogy says the 54,000-square-foot, four-acre plant, set to open in 2024, “signifies a pivotal step in [our] journey toward commercialization and its commitment to accelerating the global energy transition.”

Amogy’s ammonia-to-energy system will be assembled at the facility, located at 12221 N. Houston Rosslyn Road. So far, the system has been piloted in a drone, tractor, and semi-trailer truck. Amogy is retrofitting a tugboat to be the world’s first ammonia-powered vessel.

The startup’s product, known as a powerpack, is designed to enable carbon-free mobility in sectors such as shipping, transportation, and power generation.

“Amogy believes the adoption of ammonia as a renewable fuel will play a pivotal role in diversifying the landscape of clean energy solutions, thereby ensuring global energy security,” the company says.

Amogy plans to hire about 200 people for the Houston facility, including manufacturing workers, mechanical technicians, welders, health and safety specialists, operations professionals, and sales professionals.

“The Amogy Houston site will be a state-of-the-art facility able to manufacture our clean energy solution at scale,” says Daniel MacCrindle, chief operations officer at Amogy. “We are working quickly to hire and equip the facility so we can begin production.”

Seonghoon Woo, co-founder and CEO of Amogy, says the startup picked Houston for the facility to be close to customers, suppliers, and prospective employees.

Since being founded in 2020, Amogy has collected nearly $220 million in funding. Investors include Amazon’s Climate Pledge Fund, AP Ventures, SK Innovation, Aramco Ventures, and Mitsubishi.

Houston company closes $76M series C round to fuel its mission of reducing carbon emissions

MONEY + MATTER

A Houston-based company that is electrifying chemical manufacturing has closed its largest round of funding to date.

Syzygy Plasmonics closed a $76 million series C financing round led by New York-based Carbon Direct Capital. The round included participation from Aramco Ventures, Chevron Technology Ventures, LOTTE CHEMICAL, and Toyota Ventures. The company's existing investors joining the round included EVOK Innovations, The Engine, Equinor Ventures, Goose Capital, Horizons Ventures, Pan American Energy, and Sumitomo Corporation of Americas. According to a news release, Carbon Direct Capital will join Syzygy's board and serve as the series C director.

"We were very attracted to the multiple use cases for the Syzygy reactor and the lifetime-value of each Syzygy customer," says Jonathan Goldberg, Carbon Direct Capital's CEO, in the release. "Emissions from hydrogen production total more than 900 million metric tons of carbon dioxide per year. Syzygy's photocatalysis technology is a key solution to decarbonize hydrogen production as well as other critical industries."

Syzygy Plasmonics has a technology that harnesses the power of light to energize chemical reactions — rather than the traditional process that is fueled by heat. The Syzygy approach reduces feedstock waste and produces fewer emissions when powered by renewable electricity. According to the release, some series C participants have also formed commercial agreements to deploy Syzygy's technology to meet their decarbonization goals.

The investment funding raised will help the company to "further development and delivery of all-electric reactor systems that eliminate fossil-based combustion from chemical manufacturing and reduce the carbon intensity of hydrogen, methanol, and fuel," per the release.

"Our mission is to decarbonize chemical and fuel production," says Syzygy Plasmonics CEO and Co-Founder Trevor Best in the release. "Syzygy's aim is to achieve 1 gigaton of carbon emissions reductions by 2040, and the series C financing is a key milestone in building towards that goal.

"Closing this fundraising round with such strong support from financial and strategic investors and with commercial agreements in hand is a signal to the market," he continues. "Forward-thinking companies have moved beyond setting decarbonization goals to executing on them. Syzygy is unique in that we are developing low-cost, low-carbon solutions to offer across multiple industries."

Syzygy was founded based off a breakthrough discover out of Rice University from co-founders and professors Naomi Halas and Peter Nordlander, who invented high-performance photocatalysts. The company's collaborators then engineered a novel reactor that uses easy-to-find low-cost materials like glass, aluminum, and LEDs instead of high-cost metal alloys. After several field trials of the scalable, universal chemical reactor platform, Syzygy expects commercial units scheduled to ship in 2023.

"Syzygy is hyper-focused on aligning energy, technology, and sustainability," says Suman Khatiwada, CTO and co-founder of Syzygy, in the release. "The projects we are delivering are targeting zero-emissions hydrogen from green ammonia, low-emissions hydrogen from combustion-free steam methane reforming, and sustainable fuels made from carbon dioxide and methane. This technology is the future of chemical manufacturing."

Syzygy has raised a $23 million series B round last year following its $5.8 series A in 2019.
