Arbon

New York, NY, USA

Humidity Swing Direct Air Capture

Arbon uses a ‘humidity-swing’ process to capture CO₂ from the air. The sorbent binds CO₂ when dry and releases it when wet. This process uses less energy than approaches that rely on changing temperature and pressure to release CO₂. The sorbent’s ability to bind CO₂ has been shown to remain stable over thousands of cycles. Both of these innovations could reduce the cost of DAC.

Loam

Mildura VIC, Australia

Harnessing the power of microbes into sustainable solutions.

Loam works with 4.5 billion years of evolution to solve the climate crisis. Microbes have changed the composition of our atmosphere through earth’s history. At Loam, we are ensuring these organisms can do it again. Through a better understanding of how microbes influence the carbon cycle, we can create new planetary-scale opportunities for carbon sequestration and improve agricultural productivity.
