According to ESG Today, Arbor's carbon-removal technology relies on capturing emissions via bioenergy, while also generating around 5MW of energy per year, enough to power 4.000 households. The system, which uses existing organic waste to generate the power, is modular, meaning it can be deployed across multiple sites.

The system that converts biomass into energy is similar to that used by rockets, being developed by former SpaceX employees, so it's quite literally rocket science. Arbor will be able to use the system to capture and permanently store 75.000 tons of CO2 per year at first, the equivalent of removing 16.000 cars from the roads.

Once the company will scale the system to 100MW sometime in 2030, it will be able to remove the equivalent of 2 million tons of carbon emissions per year.

Brad Hartwig, CEO of Arbor, said that "Microsoft’s commitment to draw down their historical emissions by 2050 perfectly aligns with our mission to bring the planet back into balance with carbon-negative electricity and permanent carbon removal. This agreement underlines the promise of our technology and is another critical step in getting this project off the ground."

Brian Marrs, Senior Director for Carbon Removal and Energy at Microsoft, added that "the technical promise and modularity of Arbor’s system makes it a very compelling climate solution. Arbor has established a clear, actionable blueprint for simultaneously removing CO2 while producing clean electricity."
