You may be able to freeze them and use them later although I think egg whites freeze better than yolks. I have some cookie recipes that use just the yolks. I’ll often save up the whites from a cookie recipe in the ice cube tray in the freezer and when I get enough, make angel food cake with it. Was surprised, but frozen egg whites fluff/rise very well in angel food recipes. Cold egg whites can easily be whipped and they don’t need to be at room temperature. They just need to be defrosted You can also use yolks in omelette or crepe recipes.
