                                        REPORT

                                        [To accompany S. 1563]

                           [Including cost estimate of the Congressional Budget Office]
                    The Committee on Energy and Natural Resources, to which was
                  referred the bill (S. 1563) to authorize the Office of Fossil Energy
                  to develop advanced separation technologies for the extraction and
                  recovery of rare earth elements and minerals from coal and coal by-
                  products, and for other purposes, having considered the same, re-
                  ports favorably thereon without amendment and recommends that
                  the bill do pass.
                                            PURPOSE
                    The purpose of S. 1563 is to authorize the Department of Ener-
                  gy's Office of Fossil Energy to develop advanced separation tech-
                  nologies for the extraction and recovery of rare earth elements and
                  minerals from coal and coal byproducts.
                                      BACKGROUND AND NEED
                    Rare earth elements (REEs) are a group of 17 chemical elements
                  (the so-called lanthanides, the elements numbered 57 to 71 in the
                  periodic table, plus elements 21 and 39, which tend to occur with
                  the lanthanides in ore bodies). Their economic importance and de-
                  mand for them is increasing because their electrochemical prop-
                  erties make them useful in a wide range of consumer products, in-
                  cluding: cell phones, computer drives, and GPS devices; clean en-
                  ergy technologies, including electric motors for hybrid vehicles and
                  wind turbines; and numerous industrial, medical, and defense ap-
