Grant timeline

The application process will follow these steps and timeline. We will be in touch if we need anything further from you and to let you know if you have been invited to pitch. If you do not hear from us by the first week of June this means, unfortunately, your application has not been successful. Please note that due to the volume of applications, we will not be able to provide tailored feedback to applicants who are not invited to the pitching stage. We will publish general insights from the applications once the grants have been awarded.


  • Effectiveness - reduction relative to a typical industrial baseline
  • Reach -  breadth of the supply chain the solution can affect at scale
  • Scale – is the solution already at a mature state of commercialization and what is the potential for accelerated deployment by 2030?

Yes, the application automatically saves and you can come back to it as needed until you are ready to submit.

Please follow the link the Submittable website for guidance if you are having difficulty with your application.
