From the HRA Launch Announcement:
HRA Open is an HRA-sponsored web-based service that promotes open science by providing a space for awardees to upload and share other materials related to funded projects, including figures, datasets, presentations, and other funder-approved research outputs.
In addition to being able to deposit publications into PubMed Central (PMC), awardees can search the database of grants and awards for their awarded funding and submit their research outputs under that grant.
