The Grantham Double 100 Challenge: A new collaboration

Grantham Double 100 Challenge launches to advance capture and storage of atmospheric CO2.

In a new collaboration between the Grantham Centre and the Grantham Foundation, we’re looking for novel research. This research must have the potential to remove 100 million tonnes of carbon out of the atmosphere at US$100 or less per tonne. The successful project must also be ready for commercialisation in the near future.

Applicants in 2022 had the opportunity to work with a net zero expert from global consultancy firm McKinsey & Company to develop their proposal.

2022 winners to harness photosynthesis

The winning project for 2022 was submitted by PhD Emily Harrison and Professor Julie Gray, who proposed a biological solution.

Their project aims to harness nature’s greatest carbon capture technology: photosynthesis. Emily and Julie will explore ways of producing plants with enhanced carbon drawdown.
