You can apply to Statens Kunstfond's funding pool, Ophold på Udenlandske Residencies, if you have been accepted into a residency program that is not fully funded (ie where you have to pay for your own travel and other expenses).
Creative Europe recently launched a mobility fund for individual artists and creative professionals. The fund supports a range of activities and includes allowances for green travel, per diems, accessibility, and childcare. Applications are processed on a rolling basis until May 31, 2023.
