In addition to decreasing emissions, we need to remove CO2 that we’ve already emitted, to prevent climate change from continuing to harm our planet. And we need to do it now.
Direct Air Capture (DAC) is one of the most promising technologies to remove CO2 due to its ability to verifiably and permanently sequester CO2 for millennia. DAC is also highly scalable to remove multi-millions of tonnes of carbon without significant land use.
But there’s a catch – many DAC technologies are too expensive, electricity-intensive and need many more deployments to reach their scale potential.
Our technology was designed to operate with today’s resources and fundamental chemistry to secure our future.
We combine the natural properties of limestone with proven industrial technology to permanently remove CO2 from the atmosphere.
Green lime kiln for DAC – we use a proprietary design to drive CO2 out of limestone. Fuel flexible (e.g. ability to be low electricity-demand) with TRL 9 components.
Low-intensity contactor – we let nature do its work with simple mechanical structures that facilitate natural chemistry of the calcium-carbon loop for passive CO2 capture
High performance lime – we engineered calcium oxide, also known as lime, specifically for DAC and use Origen's breakthrough proprietary processing to maximize its ability to remove CO2 from the air
Core elements of limestone-based DAC are a kiln and contactor. We own both and are focused on their integration to come down the cost curve.
Enabled by our optimized lime production and processing, the contactor avoids significant energy use.
Origen's fuel-flexible kiln can use natural gas or biomethane with zero emissions, meaning an overall low-electricity DAC solution that is more deployable today. Limestone feedstock is highly abundant.
Scientifically proven to lock away CO2 for over 1,000 years
