Arbor’s team of world-class engineers and scientists are developing a scalable, low-cost approach to Bioenergy with Carbon Capture and Storage (BECCS) based on modern rocket engine technology. BECCS is a carbon dioxide removal (CDR) approach that uses biomass to produce energy and remove CO₂ from the atmosphere and store it permanently underground, while ensuring food security, rural livelihoods, and biodiversity are not affected. Our modular technology leverages the power density of supercritical CO2 to enable compact gasification, oxy-combustion, and high-pressure turbo-expansion to convert abundant waste biomass into clean electricity, water, and high-purity CO2, capturing and sequestering all emissions from the process.
