Renewable energy generation and mobile applications depend on innovative technologies for energy storage. The ACHEMA Special Show 2012 presents the latest technological trends and concepts. In combination with the scientific congress and closely interlinked with the whole range of process technologies on display, it offers a unique setting for the discussion of integrated and innovative solutions. The Special Show at ACHEMA 2012 from 18 – 22 June 2012, in Frankfurt puts the latest developments in energy storage and transfer at display. Chemical energy storage, fuel cells, photovoltaics and solarchemical processes are covered as well as concepts for e-mobility, innovative battery technologies and the use of hydrogen as an energy carrier. These topics are discussed in the wider context of ACHEMA showing all aspects of chemical processing and biotechnology. This creates an outstanding opportunity to develop integrated concepts and discuss potential synergies. Energy saving is an integral part of concepts for energy use. Issues regarding process intensification and energy efficiency are discussed intensively and are also a focus topic of ACHEMA 2012. The congress programme takes up the topics of the Special Show in lecture sessions on process intensification, energy efficiency and materials for energy. Plenary lectures and panel discussions round off the programme centered on the ACHEMA Special Show „Innovative Energy Carriers and Storage“ (07/2011).
