Origen Secures Funding to Advance Limestone-Based Direct Air Capture Technology

CARBON CAPTURE

Origen, a pioneering climate technology firm with operations in both the United Kingdom and the United States, has made significant strides in its mission to combat climate change through innovative carbon capture solutions. Recently, the company secured a substantial funding round for its limestone-based direct air capture (DAC) system, an investment led by Barclays Climate Ventures, with notable contributions from Shell Ventures, Exascale Fund, Elemental Impact, and Hatch. This influx of capital is strategically directed towards accelerating the development and deployment of Origen's cutting-edge DAC technology.

At the heart of Origen's system lies a unique process that utilizes limestone to effectively extract carbon dioxide from the atmosphere. The technology involves treating limestone to produce lime, which possesses the remarkable ability to passively absorb CO2 through a natural chemical process. Once captured, the carbon is carefully separated and permanently stored underground, contributing to long-term climate solutions.

Origen's commitment to advancing its limestone-based DAC technology is further evidenced by its collaborative projects. The firm has announced an ambitious facility in North Dakota, aiming to capture 1,000 tons of CO2 annually.

Additionally, plans are underway for a larger project on the Gulf Coast, which has the potential to capture an impressive 50,000 tons of CO2 per year. These initiatives not only showcase Origen’s innovative approach but also highlight the growing importance of scalable carbon capture solutions in the fight against climate change.
