'Mechanical Trees' passive carbon capture

Direct air capture is the process of capturing CO₂ from atmospheric air. Once captured, the CO₂ can be released and concentrated for sequestration or utilisation. Several companies are developing technologies to capture carbon dioxide from the air using mechanical energy to force air across a media.

A world first

MechanicalTrees™ is the world’s first passive carbon capture technology. It acts like a tree, needing only the wind to move air into the system. It is thousands of times more efficient than a tree at removing CO₂ from the atmosphere.

Silicon Kingdom Holdings (SKH) is the company responsible for MechanicalTrees™. Utilising this passive approach, they intend to make the cost of CO₂ capture economically viable and impactful towards reducing global warming at scale. The technology will be developed and deployed as full scale CO₂ farms in multiple locations, with each farm capable of removing up to 3.8 million metric tons of CO₂ annually.

PM Group has been supporting SKH in the design of a commercial scale pilot plant with services including process modelling, process design and vendor management.
“It is exciting and rewarding to collaborate with Dr Klaus Lackner, a scientific leader in direct air capture, and the teams at SKH, Arizona State University and IPEC on the design and deployment of the MechanicalTrees™,” said Tyler Underhill, Process Engineer with PM Group.

The importance of removing CO₂ from the atmosphere to meet the targets committed to by governments in the Paris Agreement cannot be understated. Knowing that every step forward is a contribution to addressing global warming is ample motivation to overcome the challenges encountered.
