8 Rivers’ Calcite and Origen Carbon Solutions announce joint project in the UK, selection by Frontier

The project has received backing from Stripe Climate’s Spring 2022 Carbon Removal Purchase cycle to the value of $1.5 million

8 Rivers Capital, LLC, and Origen Carbon Solutions, Inc., today announced a direct air capture joint project to pull a thousand tons of CO2 per annum directly from the air.

This ground-breaking project has today entered into an initial carbon removal purchase contract facilitated by Frontier, an advanced market commitment to accelerate carbon removal founded by Stripe, Alphabet, Shopify, Meta, and McKinsey earlier this year.

The project will pilot Origen’s ZerCaLTM zero-carbon lime manufacturing process and 8 Rivers’ Calcite Carbon Removal technology (“Calcite”) to demonstrate an innovative method of direct air capture – a technology that the IPCC has declared essential if the world is to achieve its net zero climate goals. The project has been selected for $1.5 million in carbon removal purchases from Stripe, a financial infrastructure company.

The ground-breaking UK/US joint project to create zero-carbon lime and use it to remove CO2 from the atmosphere has the potential to be a scalable and affordable approach to carbon removal.

Frontier’s members have committed to buy an initial $925 million of permanent carbon removal between 2022 and 2030. The goal is to send a strong demand signal that there is a growing market for carbon dioxide removal (CDR) technologies, and to then deploy these funds in a way that fast-tracks carbon removal projects and help remove billions of tonnes of carbon from the atmosphere.

Origen is an international CO₂ removal company, with ambitious plans to use its patented zero-carbon lime technology to accelerate global decarbonisation. Origen’s technology utilises limestone, a highly abundant and accessible natural resource which accounts for 10% of the total volume of all sedimentary rock on Earth. Using a new lime kiln based on novel oxy-fuel flash calciner technology, Origen can deliver CO₂ separation efficiency close to 100% to create zero-carbon lime (ZerCaLTM) with enhanced CO₂ absorption capabilities perfectly suited to carbon removal.

8 Rivers’ Calcite technology would then use this lime to pull CO₂ from the air, reducing global atmospheric carbon content. 8 Rivers, a world-leading developer of innovative decarbonization technologies, invented Calcite in 2019 and has been advancing the technology with funding from the US Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) FLECCS program. The Calcite process captures CO2 directly from air and sequesters it underground, aiming to support the world’s climate targets by removing CO2 for less than $100 per ton of CO2 at scale.

In April 2022, 8 Rivers’ Calcite Carbon Removal technology, Calcite, was named as one of fifteen milestone winners of the XPRIZE Carbon Removal funded by The Musk Foundation – with its approach to direct air capture receiving an initial $1million-dollar award.

The joint project selected by Frontier involves collaborating on a carbon dioxide removal plant in the UK to remove a thousand tonnes of CO2 from the air while piloting the scaled-up integration to enable larger-scale commercial direct air capture plants.

Ben Turner, CEO at Origen Carbon Solutions, said: “To receive this endorsement from Stripe Climate for the work we’re doing with 8 Rivers shows what can be achieved when you collaborate for good.

“Working with our partners, we know our innovative technology can build a cleaner future by removing the CO2 emissions of our past. Restoring the earth’s atmosphere isn’t just about blue-sky thinking, it’s about radical blue-sky doing. The award and recognition for this collaborative project will help us achieve the goal of reversing climate change,” he said.

In a statement, Cam Hosie, CEO at 8 Rivers said: “Scalable, economic, and rapidly deployable direct air capture is vital to help achieve our collective Net Zero goals.

“We are tremendously excited by the partnership between Calcite and Origen, aligning our complementary technologies to accelerate the removal at-scale of atmospheric CO2 while creating the market-leading pathway to meaningful direct air capture.  Stripe’s leadership is accelerating progress in direct air capture, and the Stripe Award will meaningfully shorten the path to market for these vital energy transition technologies.”

Nan Ransohoff, who leads Frontier, said: “Carbon removal is essential to achieving our climate goals, and we’re way behind schedule. But scalable, low-cost technologies like Calcite-Origen are grounds for optimism. We’re particularly excited about the diversity of approaches we’re seeing to Direct Air Capture, which likely has an important role to play in getting permanent carbon removal to gigaton-scale by 2050.”

About Origen Carbon Solutions

Origen is answering humanity’s ‘unavoidable need’ to remove CO2 from the Earth’s atmosphere. Driven by a robust and credible roadmap Origen is on a mission to achieve giga-scale carbon removal at <$100/ton by the mid-2030’s in support of its vision of the atmosphere, restored.

Today Origen is aggressively focusing on the commercial application of its ZERCAL zero-carbon lime in direct air capture (DAC) but the extreme versatility and scalability of ZERCAL has the potential to be applied to many kinds of carbon removal approaches in the future.
