![]() ![]() “It shows that the path we’ve chosen is the right one.” “While our core technology has been validated by the significant improvement of performance metrics, this external recognition further verifies our vision,” says Sahag Voskian, co-founder and chief technology officer at Verdox. This was the first round in the Musk Foundation’s four-year, $100 million-competition, the largest prize offered in history. Then, in April - after recognition as one of the year’s top energy pioneers by Bloomberg New Energy Finance - the company and partner Carbfix won a $1 million XPRIZE Carbon Removal milestone award. The carbon capture and removal startup, launched in 2019, announced $80 million in funding in February from a group of investors that included Bill Gates’ Breakthrough Energy Ventures. By Leda Zimmerman, MIT Newsīy most measures, MIT chemical engineering spinoff Verdox has been enjoying an exceptional year. Founded by MIT chemical engineers and winner of an XPRIZE Carbon Removal milestone award, Verdox is working to move the needle on climate change. Does Verdox’s electrochemical solution provide an answer? The IPCC estimates the world must remove 10 gigatons of CO2 per year by 2050 in order to keep the global temperature rise under 2☌. Today’s infant carbon capture start-ups are criticised for their slow progress towards commercialisation and scale. Verdox has its first commercial client, Norwegian aluminium company Hydro, which wants to eliminate CO2 from the exhaust of its smelters. Launched in 2019, Verdox received $80m in funding in February, along with a string of high-profile prizes. The small charge required means the system’s energy consumption is very low compared to other technologies. The technology works in a wide range of CO2 concentrations, from the 20% or higher found in cement and steel industry exhaust streams, down to the very diffuse 0.04% in air itself. When it’s time to store it away, the charge is reversed and the gas is expelled as a pure stream of CO2. ![]() Electrodes are coated with polyanthraquinone. Leda Zimmerman at MIT describes a method of removing CO2 electrochemically, now being taken forward by MIT spin-off company Verdox. ![]()
