Yama

Up to 10 Gts of CO2 removal will be needed each year by 2050, with Direct Air Capture (DAC) playing an essential role to help us stay below 1.5°C. However, no DAC technology has cracked the Gt scale yet due to high energy requirements, water consumption, land usage, and material availability.

Yama solves DAC scalability by integrating low-grade heat sources into a hybrid electrochemical / thermal desorption process to reduce energy consumption by 30% and Capex by 10% compared with standalone electrochemical systems. Yama uses low-temperature heat pumps and ambient heat to achieve desorption at temperatures <100°C, and integrates an absorption fan to cut water consumption by 50%. By using high TRL components from existing supply chains, Yama targets 550 kWh/tCO2 and $70/tCO2 at scale.
