    Powerful Mechanical Trees Can Remove CO2 From
    the Air to Combat Global Warming at Scale

    TEMPE, Ariz. & DUBLIN–(BUSINESS WIRE)–Arizona State University (ASU) and Silicon Kingdom Holdings (SKH)
    announce an agreement to deploy carbon capture technology developed by
    Professor Klaus Lackner, director of ASU’s Center for Negative Carbon
    Emissions (CNCE).

    The proprietary technology acts like a tree that is thousands of times
    more efficient at removing CO2 from the air. The “mechanical
    trees” allow the captured gas to be sequestered or sold for re-use in a
    variety of applications, such as synthetic fuels, enhanced oil recovery
    or in food, beverage and agriculture industries.

    Unlike other carbon capture technologies, SKH’s technology can remove CO2
    from the atmosphere without the need to draw air through the system
    mechanically, using energy intensive devices. Instead, the technology
    uses the wind to blow air through the system. This makes it a passive,
    relatively low-cost and scalable solution that is commercially viable.
    If deployed at scale, the technology could lead to significant
    reductions in the levels of CO2 in Earth’s atmosphere,
    helping to combat global warming.

    CO₂ is an odorless, colorless gas that is a byproduct of burning fossil
    fuels and other natural processes. Humans release more than 36 billion
    metric tons of CO2 into the atmosphere annually,
    significantly changing Earth’s natural carbon cycle. The excess carbon
    traps heat and causes global warming.

    The situation has gotten to the point where we need to stop talking
    about it and start doing something about it,” said Lackner, an ASU
    engineering professor in the School of Sustainable Engineering and the
    Built Environment. “Carbon dioxide is a waste product we produce every
    time we drive our cars or turn on the lights in our homes. Our device
    can recycle it, bringing it out of the atmosphere and either bury it or
    use it as an industrial gas,” added Lackner, who will serve as the chief
    scientific adviser to SKH.

    The “mechanical tree” is a novel geometry which is agnostic to the wind
    direction. Each one contains a stack of sorbent filled disks. When the
    tree-like column is fully extended and the disks spread apart, air flow
    makes contact with the surfaces and the CO₂ gets bound up. During
    regeneration, the disks are lowered inside the bottom container. Inside
    the chamber, the CO2 is released from the sorbent. The
    released gas is then collected, purified, processed and put to other
    uses, while the disks are redeployed to capture more CO2.

    Until now, technologies being developed to capture CO2 from
    the air have been constrained by the cost of capture and the ability to
    harvest the gas at scale. The technology to be deployed by SKH addresses
    both issues, bringing the cost of capture comfortably below $100 per
    metric ton at scale – the lowest in the industry – making it both
    commercial and impactful towards reducing global warming.

    SKH plans to deploy clusters of column shaped devices, or “mechanical
    trees.” A cluster comprises 12 columns and can remove 1 metric ton of CO2
    per day. SKH will deploy the technology in a pilot CO2 farm
    targeting 100 metric tons per day of CO2. The technology will
    then be deployed to full scale CO2 farms in multiple
    locations, each capable of removing up to 3.8 million metric tons of CO₂
    annually.

    SKH holds the exclusive rights to the technology and comprises a group
    of leading individuals from business and science, including Lackner.
    Through the relationship with ASU, SKH will support ASU research and ASU
    owns an interest in the shares of SKH.

    Our goal is to accelerate the global climate effort set out in the
    Paris Agreement to contribute to reversing global carbon emissions in
    the next 10 to 15 years,” said Pól Ó Móráin, CEO of SKH. “Our passive
    process is the evolution of carbon capture technology which has the
    ability to be both economically and technologically viable at scale in a
    reasonably short time frame,” added Ó Móráin.

    The development of Klaus Lackner’s carbon capture device is but one
    example of how ASU is developing novel technologies and business
    opportunities to improve the environment and ensure a healthy Earth for
    all well into the future,” said Peter Schlosser, vice president and vice
    provost for Global Futures at ASU. “We are excited to be working with
    SKH to bring this important technology for limiting global warming to
    market.”
