Static method and TempData, what is another alternative?

I'm trying to find  a way to pass  a TempData from a static method to another method but I'm having some issue finding the correct answer to this problem bellow, since I can't use a TempData in a static field..

   
 public static XtraReport BuildReportObject(DailyEmployeeRecapSearchCriteria searchCriteria)
        {
           var resultsContainer = GetReportResults(searchCriteria)
           TempData['"value"] = resultsContainer;  I can't do this, since its a static field.
          ........

          return SetDefaultsForReportObject(mainReport, .....
        }

why I wanted to use a TempData so that I could use it into another method.

 public FileResult ExportCsvFormat(string dataSource)
        {
  foreach (var x in (List<GroupBillingCustomerDetails>)TempData["GroupBillingdata"])  > Then here I can use my TempData ...
                {

}.....
