Are the open access related rules that apply to ERC grantee any different from those that apply to researchers funded under the rest of Horizon 2020? | ERC: European Research Council

"An overview of the open access related rules for ERC funded researchers can be found on the ERC website. Note that Article 29.2 of the ERC Model Grant Agreement is slightly different from the corresponding article in the general Horizon 2020 Model Grant Agreement. Details on the application of the article to ERC grants can be found in the ERC specific part of the Annotated Model Grant Agreement."
