The review of world trends over 2009 - 2012 years in the field of clear energy is presented. Advantages and disadvantages of the developed and commercial sodium batteries, direct methanol fuel cells and aluminum-air batteries with replaceable electrodes are discussed. We describe the main advantages of methanol energy in comparison with hydrogen. Basic advantages of methanol economics over hydrogen were described. New results of experimental investigations of beta-alumina ceramics with proton conductivity are presented. Two new methods of post processing of sintered membranes providing the value of ionic conductivity at the best world level along with negligible electronic conductivity are proposed. A room direct methanol fuel cell based on the beta-alumina membrane and the planar model of aluminum-air battery with the ceramic separator between anode and cathode sections were assembled and tested.
