Who Are Origen?

Origen is a climate tech company specialising in developing innovative solutions to abate and remove carbon dioxide from the atmosphere.

Founded in 2013 following ground-breaking research at the University of Oxford, Origen’s ZerCaL™ technology decarbonises carbon-intensive minerals processing such as calcium oxide, commonly known as lime.

It is the production of zero-carbon lime — along with lime’s natural CO2 absorbing properties — that is elemental to Origen’s carbon removal ambitions.

Not only is Origen exploring new ways to decarbonise the lime industry and those sectors that rely on this essential mineral, but this zero-carbon lime can also be used in innovative carbon dioxide removal (CDR) projects to permanently remove CO2 from the atmosphere.

Leveraging the core ZerCaL™ technology, Origen is developing new innovative methods to enable multiple ways to achieve giga-scale low-cost CDR from the atmosphere.

Indeed, CDR is recognised by the IPCC as being essential if we are to achieve net zero, something that is crucial if we are to achieve the 1.5-degree climate target and avoid the worst impacts of climate change.

Headquartered in the UK, Origen also has a presence in the US, with plans to expand its strategic partnerships to accelerate its production of zero-carbon lime.
