What Verdox, Inc. does

Verdox, Inc. is a privately held Massachusetts-based MIT spinoff founded in 2020 that develops electrochemical systems for carbon capture from industrial emissions and ambient air. The company's core product is an Electro-Swing Adsorption (ESA) platform that uses an electrochemically active quinone molecule which binds CO2 when reduced to its active state and releases CO2 when oxidized, eliminating the heating and cooling cycles required by conventional thermal swing adsorption. Verdox reports energy consumption of 1.5 GJ per ton of CO2 captured, which is approximately 70% lower than conventional technologies, and the system operates at all CO2 concentrations from ambient air at ~400 ppm to industrial flue gas above 10%, with its largest cost advantage at ultra-dilute streams below 2% where traditional capture is economically unviable. The technology is modular and compact, leveraging commercially available equipment, with a stated footprint of approximately 0.01 m2 per ton of CO2 capacity and resilience to industrial contaminants.

Verdox targets large industrial emitters via an enterprise field sales motion, with named segments spanning metals and smelting, chemical production, power and utilities, oil and gas, and industrial manufacturing, alongside direct air capture. The business model centers on hardware sales of capture systems deployed at customer sites, with likely long-term service and consumables revenue, and pricing is custom-quoted per deployment rather than publicly disclosed. The company has built strategic investor and pilot relationships with Norsk Hydro for aluminum smelting decarbonization, with Carbfix as the CO2 mineralization partner for the XPRIZE Carbon Removal Award, and has assembled an investor base including Breakthrough Energy Ventures, Lowercarbon Capital, Prime Coalition (now Azolla Ventures), and Bill Gates. The technology is protected by more than 20 granted patents combining MIT-originated invention with proprietary advancements.

The company has raised approximately $81M in total disclosed funding through a February 2022 $80M Series A and an April 2022 $1M XPRIZE award, and has received external recognition including TIME World's Top Greentech Companies of 2025, 2023 Global Cleantech 100, BNEF Pioneer 2022, and Massachusetts Climate Tech Leader 2024. Leadership combines MIT-originator scientific founders Sahag Voskian and T. Alan Hatton, chairman and serial entrepreneur Brian Baynes, and commercial CEO Friedrich von Gottberg, whose prior experience at Cabot Corporation and Voxel8 indicates the company's pivot from laboratory research toward industrial commercialization.

Core offering

Verdox develops and deploys a fully electric, modular electrochemical carbon capture system based on its proprietary Electro-Swing Adsorption (ESA) technology. The system captures and releases CO2 using electrical energy alone, eliminating the need for heat or water, and operates across all CO2 concentrations from dilute ambient air (~400 ppm) to concentrated industrial flue gas (>10% CO2). It is targeted at industrial point-source emitters and direct air capture applications, with pilot demonstrations on aluminum smelter off-gas at 1% CO2.

Product overview

Verdox offers a single unified core product: its electrochemical carbon capture system based on Electro-Swing Adsorption (ESA) technology. The system captures CO2 using an electrochemical process where quinone molecules are activated, bind with CO2, and then release it through electrical energy alone. This technology is designed for industrial point-source applications and direct air capture (DAC), with a modular architecture enabling deployment at any scale.
