We make modular, renewable energy-powered direct air capture (DAC) machines that can be connected in large arrays to remove massive amounts of CO2 from the atmosphere.
In order to achieve climate targets, we need to do everything we can to reduce emissions. Unfortunately, mitigation alone won’t get us to net zero; negative emissions technologies like DAC are critical to reaching the Paris Agreement goals. To keep global warming to under 1.5°C by 2100, leading studies show that negative emissions technologies will need to remove in the order of 10-15 gigatons a year by 2050.
CarbonCapture’s direct air capture machines draw in large amounts of air using powerful fans. The air is first dehumidified before entering a reactor that containing zeolites, which capture CO2 as well as any remaining water (“adsorption”). After the zeolites reach their capacity, a vacuum is pulled and the reactor temperature is raised, releasing concentrated CO2 and water into collectors (“desorption”). The reactor is cooled, and a new cycle begins.
CarbonCapture has developed a set of technical innovations that enable, for the first time, the use of zeolites for capturing CO2 as part of a commercial direct air capture system. A class of molecular sieves, zeolites are inorganic, inexpensive, long-lasting, and non-toxic. Moreover, they are already manufactured in very large quantities for multiple industrial applications, eliminating a major barrier to economically scaling direct air capture facilities to gigaton levels.
