In this paper we study the clustering of SZ-selected galaxy clusters on apast light-cone, particularly paying attention to the possibility ofconstraining properties of dark energy. The prospects of detecting baryonicfeatures in the cluster power spectrum for a wide and shallow survey likePLANCK, and for an SPT-like narrow and deep survey are discussed. It isdemonstrated that these future blank sky SZ surveys will have capability toimprove significantly over the recently announced detection of baryonicoscillations based on the SDSS Luminous Red Galaxy (LRG) sample. We carry outparameter estimation using Fisher matrix approach taking into account theanisotropic nature of the power spectrum due to redshift space and cosmologicaldistortions. The clustering signal which is not too sensitive to systematicuncertainties serves as a valuable piece of information that in combinationwith other sources of data helps in breaking degeneracies between thecosmological parameters.Comment: 18 pages, 17 figures, version accepted in A&
