The U.S. Department of Energy's mission is to "ensure America's security and prosperity by addressing its energy, environmental and nuclear challenges through transformative science and technology solutions."
The DOE's Office of Science provides research funding for energy and physical sciences to academic institutions across the U.S.
To see currently funded research grants on a state by state level, see Office of Science Interactive Grants Map.
The Department of Energy Public Access Plan requires investigators receiving DOE funding to "submit metadata and a link to the full-text accepted manuscript (or the full text itself)" to the DOE's Office of Scientific and Technical Information.
The policy applies to award agreements issued or renewed after October 1, 2014.
Final, peer-reviewed manuscripts can be submitted using the E-Link system to complete the AN 241.3 form.
Instructions for completing the AN 241.3 can be found here.
A tool specifically for submitting accepted manuscripts is also available.
The manuscript version required is the final, peer-reviewed manuscript version. The DOE also refers to this as an accepted manuscript. This manuscript is the version of the article that has been accepted for publication and includes all changes made by the author during the peer-review process. It does not include the publisher's formatting.
The time before an article will be freely available to the public is typically called the embargo period.
For the DOE, there is a 12-month embargo from date of publication. Please note that the DOE refers to this as an "administrative interval".
The DOE repository is Public Access Gateway for Energy and Science (PAGES).
